HIGH PERFORMANCE POWERTRAIN
Under the rakish hood of the 2003 3.2 TL and TL Type-S are two variants of Acura's 3.2-liter, 24-valve, VTEC V-6 powerplant. The 3.2 TL's engine delivers 225 horsepower at 5600 rpm and a broad torque curve with peak output of 216 lb-ft. at 4700 rpm. The high-performance TL Type-S engine uses a dual-stage induction system and numerous other performance enhancements to boost horsepower to 260 at 6100 rpm. The Type-S engine's maximum 232 lb-ft. of torque is available between 3500 rpm and 5500 rpm.

Both engines in the 2003 TL feed their power to an electronically controlled 5-speed automatic transmission equipped with the Sequential SportShift' system. Similar to the transmission first unveiled in the exotic Acura NSX sports car, the Sequential SportShift system allows the driver to shift gears semi-manually simply by moving the shift lever fore or aft in a special SportShift gate. If the driver prefers, the transmission also offers the shifting convenience of a conventional automatic. Additionally, the transmission is equipped with Grade Logic Control programming for enhanced shifting smoothness and reduced gear "hunting" when climbing or descending steep grades.

The 3.2 TL powertrain's impressive power output does not come at the expense of vehicle emissions. Both the 3.2 TL and TL Type-S meet stringent Low Emission Vehicle (LEV) standards, while California models (3.2 TL only) comply with Ultra Low Emission Vehicle (ULEV) standards.

GLOBAL MIDSIZE PLATFORM
The unit-body of the '03 TL is based on the Global Midsize Platform (also shared with the Acura CL coupe), which positions the front-drive powertrain in a transverse orientation for maximum cabin volume and optimum weight distribution. To reduce Noise, Vibration, and Harshness (NVH), the front and rear suspensions are carried on isolated subframes - resulting in exceedingly low interior noise levels. Insulation material in the doors provides additional noise isolation. Gap-filling foam in the side pillars helps seal the pillar cavities from further noise intrusions. Computer-designed cabin reinforcements and specially designed crumple zones in the front and rear help protect the passenger cabin in the event of an impact. The TL's fully independent, double-wishbone suspension system includes large wheels and tires (16-inch on the TL; 17-inch on the TL Type-S) for reassuringly secure handling. The compact, multi-link, double-wishbone rear suspension contributes to the exceptional spaciousness of the TL cabin and trunk.

ABUNDANT STANDARD LUXURIES AND CONVENIENCES
The automotive press and the public have praised the TL for its long list of standard luxury equipment, and the 2003 edition continues in this class-leading tradition. From a leather-trimmed interior with heated front seats to a power moonroof, keyless entry system, and an Acura/Bose® Music System with an in-dash, 6-disc CD changer, the TL is designed to provide a truly comprehensive array of fine amenities as standard equipment.

The TL also offers the optional Acura Navigation System, which provides satellite-linked nationwide coverage through a DVD on-board database that lists information on 3.7 million points of interest. New for 2003, all TL models equipped with the Acura Navigation System also feature the OnStar® communications and assistance service as standard equipment. The OnStar® service offers Acura drivers access to a wide range of services including route guidance, vehicle assistance from a live OnStar® advisor, Internet access and personal phone calling.

SLEEK AND ELEGANT EXTERIOR DESIGN
The sporty, athletic lines of the TL were designed to accentuate the car's aggressive demeanor. Graceful, athletic proportions reflect the TL's focus on delivering personal driving satisfaction. Distinctive and refined in its lines, the TL's exterior makes a strong statement, echoed by the cockpit feel of its leather-trimmed interior.

The TL is available in an array of colors including White Diamond Pearl, Satin Silver Metallic, Naples Gold Metallic, Firepepper Red Pearl, Aegean Blue Pearl, Eternal Blue Pearl, Noble Green Pearl, Anthracite Metallic, and Nighthawk Black Pearl.

In fall of 2002, the TL will receive two new exterior colors with Desert Mist replacing Naples Gold and Royal Ruby replacing Firepepper Red.

SPORTY AND SPACIOUS INTERIOR
The 2003 Acura 3.2 TL provides ample room for both passengers and cargo, thanks in part to a generous 108.1-inch wheelbase. With an interior totaling 110.5 cubic feet in volume, the TL is officially classified by the EPA in the midsize class. Most of the TL's competitors, in contrast, are classified as compact cars.

Large analog gauges and important switches are grouped around the steering wheel for intuitive operation. A generous greenhouse provides superb visibility. Rich, hand-selected leather graces the seats and interior trim, while the cabin is further refined with elegant wood-patterned accents. Befitting its sportier role, the 3.2 TL Type-S cockpit is equipped with racy perforated-leather sport seats, a perforated-leather steering wheel and shifter, a Type-S emblem on the shift knob, and metallic-face gauges.

2003 Acura 3.2 TL - Powertrain

OVERVIEW
The 3.2 TL is powered by an all-aluminum, 3.2-liter V-6 that uses 24 valves and Acura's innovative VTEC system to deliver 225 horsepower and 216 lb-ft. of torque. The V-6 in the high-performance TL Type-S model builds upon this potent foundation by adding a high-flow, dual-stage induction system and a free-flowing exhaust - which help boost output to 260 horsepower and 232 lb-ft of torque.

In each engine, Acura's patented VTEC system - first unveiled on the NSX exotic sports car - helps provide an exceptionally flat torque curve, enhanced engine breathing, and superb responsiveness at all engine speeds.

Both the TL and the TL Type-S are equipped with an electronically controlled, 5-speed Sequential SportShift transmission. Inspired by the transmissions used on modern Formula One race cars, Sequential SportShift allows the driver to shift the forward gears semi-manually - without the need for a clutch pedal. The transmission also offers the shifting convenience of a conventional automatic.

In keeping with Acura's commitment to the environment, both TL engines meet stringent Low Emission Vehicle (LEV) standards. The California-model 3.2 TL also meets Ultra Low Emission Vehicle (ULEV) requirements.

ENGINE ARCHITECTURE
The TL features a sophisticated, 24-valve, 3.2-liter V-6 engine. In addition to its lightweight, all-aluminum construction and compact, smooth-firing, 60-degree layout, the engine incorporates such state-of-the-art technologies as the VTEC system and a high-flow induction system to combine prodigious power with smooth, refined operation. In addition, the high-performance Type-S V-6 uses a unique, dual-stage induction system to boost output to 260 horsepower.

ENGINE BLOCK
The compact, aluminum engine block of the TL V-6 is die-cast and heat-treated for exceptional rigidity and minimal resonant vibration. The engine's iron cylinder liners have their bore pitch set at a close 98-mm spacing to reduce overall engine size. The free-revving TL engine is oversquare with a bore of 89 mm and a stroke of 86 mm - yielding a total displacement of 3210 cc.

The TL employs an engine cylinder bank V-angle of 60 degrees for improved smoothness and compact size. The block has an unusually short deck height, resulting in an overall reduction in the height and width of the assembled engine.

While both TL models have iron cylinder inserts, the Type-S engine adds unique spin-cast cylinder-wall liners that are cast into the engine block during the initial manufacturing phase. These spin-cast liners are lighter than traditional iron liners - and also improve heat dissipation to avoid engine knocking. Because they require fewer machined surfaces, spin-cast cylinder liners also simplify the production process.

CYLINDER HEAD
The powerful TL engines incorporate pressure-cast, aluminum alloy cylinder heads with four-valves-per-cylinder, compact combustion chambers, and a generous squish area to promote swirl and enhance combustion efficiency. For enhanced flow into the combustion chamber, the Type-S engine has specially designed, race-bred intake valves. The single overhead camshaft in each cylinder head is installed from the timing belt side of the engine, saving weight and complexity by eliminating the need for bolt-on cam caps. The cams are driven by the crankshaft via a fiberglass-reinforced, toothed timing belt and use friction-reducing roller followers to activate the valves.

CRANKSHAFT/CONNECTING RODS/PISTONS
Of paramount importance in designing the TL's V-6 was the goal of compact overall engine dimensions. The TL engine uses a rigid, forged crankshaft and narrow 19 mm connecting rods to reduce engine length and width. Rather than conventional nut-and-bolt type fasteners, the connecting rods in the TL V-6 use lightweight bolts (without nuts) called plastic-region fasteners. The rod bolts thread directly into the connecting rod allowing the bolts to be smaller while retaining the required clamping force and strength margins.

The V-6's compact pistons are made of lightweight, cast-aluminum alloy. A unique dome-shaped design provides maximum combustion efficiency in each combustion chamber. The compression ratio is 9.8:1 in the 3.2 TL and 10.5:1 in the Type-S due to a taller piston dome. The pistons utilize a 3-ring design with the Type-S engine incorporating a unique angled top ring for an improved seal within the cylinder to accommodate the higher combustion pressure.

VARIABLE VALVE TIMING AND LIFT ELECTRONIC CONTROL (VTEC)
First unveiled on the Acura NSX supercar, the innovative Variable Valve Timing and Lift Electronic Control (VTEC) system is a key player in the TL engine's remarkable combination of low end torque, high-rpm horsepower, fuel efficiency and low exhaust emissions.

Unlike engines with conventional fixed-timing intake valves, the TL's VTEC engines automatically optimize the intake valve settings for either low or high-rpm operation. By altering the lift and opening duration of the intake valves depending on engine rpm, VTEC helps the engine produce abundant low- and mid-range torque with no sacrifice in high-rpm power. At high rpm the VTEC V-6 produces considerably more horsepower than other engines of its size.

At low rpm, the VTEC intake valves follow a set of low-lift, short-duration cam lobes with timing that optimizes cylinder filling. In addition, the timing of the intake valves is staggered and their lift asymmetric - creating a swirl effect within the combustion chambers at lower RPM. The result is increased burn speed with improved combustion stability and an increase in allowable EGR rate. As the engine spins through 4400 rpm (4800 rpm on the Type-S), the intake rocker arms transition to actuation by high-lift, long-duration cam lobes designed to optimize high-rpm output.

On the Type-S, high-performance camshafts further increase power output by providing longer intake-valve duration, more valve overlap, and additional lift for the exhaust valves.

DUAL-STAGE INDUCTION SYSTEM
Found only on the Type-S engine, this revolutionary dual-stage induction system is a major contributor to producing the V-6's robust 260 horsepower. At its heart, the system uses a large, two-chamber intake plenum separated by an electronically actuated butterfly valve, which opens at 3800 rpm.

At low and mid-range engine speeds, the valve is closed - creating a Resonance Charge condition where pressure pulsations between cylinders banks are separated. In doing so, air filling the cylinders increases with the resonance energy from the adjoining cylinder of each bank (Helmholtz principle).

At mid to high engine rpm, an electric motor opens the butterfly valve and an Inertia Charge condition is achieved. Increased air filling then occurs when the manifold volume is increased and the resonance charge condition is eliminated. This phenomenon utilizes the high flow mass to pressurize the manifold port air, producing a natural "supercharger" effect.

The increased airflow and improved cylinder filling is the fundamental reason for the engine's efficient combustion and increased power. Additional improvements include a larger 64-mm bore throttle body (which reduces air-intake restriction and increases total air flow volume), free flow exhaust, and a low-overall restriction air intake system with a free flow air filter and air flow tube.

PROGRAMMED FUEL INJECTION (PGM-FI)
A Programmed Fuel Injection (PGM-FI) system controlled by a 16-bit, 32 MHz Powertrain Control Module (PCM). The PCM utilizes position sensors on the crankshaft and both camshafts to monitor many variables including throttle position, engine temperature, intake manifold pressure, atmospheric pressure, exhaust gas oxygen content, and intake air temperature. The PGM-FI system controls fuel delivery by six injectors mounted in the cast aluminum, tuned-length intake manifold.

EXHAUST SYSTEM
The lightweight, high-flow, dual-exhaust system in the 2003 TL is designed for low-restriction performance with minimal noise and vibration. The high-output Type-S engine has a larger-diameter exhaust pipe, an increased-flow, low-restriction catalytic converter, and ultra-high-flow capacity dual silencers. The result is a 30 percent increase in exhaust gas flow compared with the 3.2 TL. The Type-S also boasts an aggressive, performance-oriented exhaust note that settles into a subdued tone at cruising speeds. Both the 3.2 TL and the TL Type-S meet LEV standards while the California-edition 3.2 meets ULEV standards

DIRECT IGNITION SYSTEM/KNOCK CONTROL
While proper ignition timing is critical to optimized engine performance and emission control, proper timing depends on many variables and constantly changes from moment to moment. If there is not enough spark advance, fuel efficiency suffers. If there is too much advance, engine knock or even engine damage may occur. The TL is equipped with a new-generation knock-control system. Using a centrally located engine-block sensor that "hears" the onset of knocking, the system can advance ignition timing to the point of peak efficiency - without going beyond. The system is even able to adapt if the quality of fuel used is less than the specified unleaded premium.

The ignition system further benefits from compact and reliable direct-ignition coil units, which are positioned directly in the spark plug access bores.

NOISE, VIBRATION, AND HARSHNESS (NVH) CONTROL
In addition to power and fuel efficiency, the TL powertrain was engineered for superb smoothness and noise control. To that end, the TL's V-6 engines incorporate such NVH-reducing features as a rigid aluminum block with an unusually high resonant frequency, a rigid forged crankshaft, die-cast accessory mounts, and a stiff, cast-aluminum oil pan.

105,000-MILE TUNE-UP INTERVALS
For the first 105,000 miles, the TL engines require only routine inspections and fluid and filter changes. Thanks to the roller-follower design of the VTEC valvetrain, friction and wear are reduced to the point that the screw-type tappet clearance adjusters need not be checked until the 105,000-mile mark. At that point, the long-life, platinum-tipped spark plugs are also scheduled for replacement.

DIRECT-ACTING CRUISE CONTROL
For relaxed highway cruising, the TL is equipped with a sophisticated electronic cruise-control system. When engaged, the system's Powertrain Control Module (PCM) is able to command the 5-speed transmission directly, summoning downshifts as required to help maintain the driver's preset road speed even when climbing steep grades. For added convenience, the cruise control is operated using buttons on the steering wheel. Using these buttons, the driver can adjust road speed up or down in one mph increments or disengage the cruise-control system without touching the brake pedal.

5-SPEED, SEQUENTIAL SPORTSHIFT' AUTOMATIC TRANSMISSION
The TL features a 5-speed automatic transmission with an advanced Sequential SportShift feature as standard equipment. Inspired by the transmissions found on contemporary Formula One Grand Prix racecars, Sequential SportShift allows the driver to choose the convenience of a conventional automatic or shift gears semi-manually. To do the latter, the driver places the gear lever in a special SportShift gate to the left of the D5 position and then simply moves the lever fore or aft to shift up or down. The selected gear is displayed on an LED indicator inside the tachometer face.

To improve the immediacy and "manual-transmission feel" of the shifting experience in SportShift mode, the transmission computer commands shifts that are firmer and approximately 10 percent quicker than those in automatic mode. At the same time, the SportShift system incorporates built-in safety-override features unavailable with a conventional manual transmission. For instance, the transmission logic will not allow a downshift that would cause the engine to over-rev.

The TL's 5-speed automatic transmission figures heavily in measured performance gains and performance driving feel. Its gear ratio settings closely match the demands of a variety of driving situations. The wide ratio transmission's lower gears provide quick acceleration while the tall top gear ratio results in low cruising rpm's for reduced engine noise and lower fuel consumption.

Thanks to a design that shares the idler and third-gear clutches, the TL's transmission provides five ratios in a unit about the size of a conventional 4-speed transmission. The transmission also incorporates a first gear one-way clutch for smoother shifts, plus an innovative heat exchanger design that moderates transmission operating temperature quickly and without undue complexity.

Linear solenoids provide precise, real-time control of the clutch on/off pressure in the TL's transmission. Thanks to this superior clutch-engagement accuracy, the control logic system operates smoothly under all conditions. For added refinement, a bearing supports the idler shaft.

To manage overall powertrain operation, the PCM interacts with multiple control strategies. For instance, by limiting engine output torque and/or transmission clutch pressure, harsh driveline shocks are eliminated. The system also prevents the engine from exceeding 5000 rpm when the transmission is in neutral or park.

GRADE LOGIC CONTROL
To improve powertrain smoothness and reduce gear "hunting" on steep grades, the 5-speed automatic transmission is equipped with a standard Grade Logic Control system. Using sensors that monitor throttle position, vehicle speed, and acceleration/deceleration the system compares these inputs with a map stored in the transmission computer, determines when the vehicle is on an incline and adjusts the automatic shift schedule for improved climbing power or downhill engine braking.

2003 Acura 3.2 TL - Chassis

OVERVIEW
The TL was built with the ambitious goal of providing world-class refinement and exceptional handling performance. It is built on the Global Midsize Platform, a front-drive platform that combines the packaging efficiency and handling stability of a transversely mounted front-drive powertrain with Acura's latest chassis and suspension advances.

The chassis architecture of the TL has been carefully designed to provide the crisp handling dynamics demanded by driving enthusiasts and the world-class ride refinement expected by drivers of mid-luxury sedans. The TL employs front and rear suspension subframes and carries its engine on electronically-controlled hydraulic mounts. The 4-wheel independent suspension system benefits from geometric refinements that reduce understeer at the limit of adhesion and improve the TL's responsiveness. Standard 16-inch wheels on the TL and 17-inch wheels on the Type-S provide exceptional cornering grip.

The Type-S model's suspension has been tuned to provide even more exceptional handling, incorporating a larger-diameter rear stabilizer bar, stiffer front and rear springs, more compression and rebound damping, and longer front bump stops.

FRONT SUSPENSION
The 3.2 TL utilizes a race-proven, double-wishbone suspension layout for exacting wheel-motion control. The front suspension has been carefully designed to exploit the stiffness of the front subframe, while the TL's low 57-mm roll center further contributes to the car's precise and linear handling.

To suit its more athletic demeanor, the Type-S front suspension is tuned for even greater handling performance. Revisions to the suspension include stiffer springs, a 10 percent increase in the damping rates, and a 20-mm longer bumpstop. These enhancements help the car maintain an optimum stance during cornering for superb handling and responsiveness.

REAR SUSPENSION
At the rear, the TL's multi-link suspension layout has been designed for rewarding handling and a fluid ride without sacrificing cabin or trunk room.

Compact, high-tension steel suspension links reduce unsprung weight for enhanced damping control. The suspension geometry is designed to carry the rear wheels through a path that is angled rearward to improve bump compliance. This sophisticated geometry also provides a much straighter toe curve, meaning that during suspension motion there is a controlled amount of "rear steer." Pillow joints help control side-force steer while reducing component friction - improving ride comfort.

In the high-performance Type-S, the rear suspension - like the front - is tuned with stiffer springs, higher compression and rebound damping and a larger-diameter rear stabilizer bar for reduced body roll during cornering.

FRONT AND REAR SUBFRAMES
Stout front and rear subframes improve the TL's chassis rigidity and help curb NVH. In the front, a perimeter frame - consisting of a front member, side members and a rear bulkhead beam - significantly improves chassis stiffness while also enhancing front-impact crash protection.

The rear subframe also utilizes a large perimeter frame, consisting of robust cross-section members and smaller stringers that locate the rear suspension and house the fuel tank.

Both the front and rear subframes are mounted to the body with rubber isolators that help dampen vibration by as much as 5 db in the low- and mid-frequency ranges.

HYDRAULIC ENGINE MOUNTS
To enhance the world-class refinement of the TL even further, the V-6 engine is mounted to the subframe with two electronically controlled, hydraulic engine mounts and a side stopper mount. The hydraulic mounts help to isolate the cabin from engine vibration. To do so, each mount controls fluid transfer between two internal hydraulic chambers, thereby altering the mount's damping frequency and helping to counter any engine vibration.

STEERING
To deliver both the smooth refinement of a premium luxury automobile and the rewarding response of an athletic sports sedan - the 3.2 TL and the TL Type-S are equipped with unique power-steering systems.

The 3.2 TL features a speed-sensitive, variable power assist system designed to complement the model's handling characteristics.

By varying the amount of power assist according to vehicle speed, the system provides light steering effort during low-speed parking maneuvers and, as vehicle speed increases, progressively heavier steering effort for a positive and secure feel.

The TL Type-S is equipped with an exclusive sport-tuned, power steering system (similar to the CL Type-S). The Type-S uses a torque-sensing rotary valve steering gear that varies the amount of assist according to steering input and the resultant torque generated between the pavement and tire. The system also varies assist based on engine speed, helping make steering light in parking maneuvers and heavier as speed increases for enhanced road feel.

The steering column is insulated from intrusive road harshness by a rubber coupling.

BRAKING SYSTEM
For superb braking power and excellent resistance to fade, the TL is equipped with 11.8-inch (300 mm) ventilated front brake rotors and 11.1-inch (282 mm) rotors at the rear. Rigid front calipers help provide crisp, responsive pedal feel, while system-wide tuning of the brake components helps ensure linear brake-pedal action and predictable effort.

The service and parking brakes on the rear wheels are separated for further improvements in brake performance. A drum-in-disc brake design uses the disc portion of the rear unit for braking at speed, while the drum is used only as a parking brake. The parking brake operates with a push on/push off floor pedal.

TRACTION CONTROL SYSTEM (TCS)
To enhance stability and control while increasing all-weather usability, the TL features a standard Traction Control System (TCS). Under acceleration, the TCS can detect wheel slip and, if necessary, coordinate modulated braking to help the front tires regain traction. Operating at vehicle speeds below 18 miles per hour, the system can apply one or both front brakes as necessary to control wheel spin.

Because the system provides independent drive-wheel control, it also greatly enhances performance when accelerating on surfaces with split-traction coefficients. When starting out on split-traction surfaces (i.e., one side of the car is on dry pavement while the other side is on wet pavement), TCS can apply braking action to whichever front wheel is slipping - allowing the tire with the better grip to propel the vehicle.

ANTI-LOCK BRAKING SYSTEM (ABS)
The ABS system in the 3.2 TL is a three-channel design that modulates braking power to the front wheels independently and to the rear wheels in tandem - enhancing driver control during maximum-effort stops on all road surfaces.

The TL Type-S is fitted with a four-channel ABS system that works in conjunction with the Vehicle Stability Assist (VSA) system. When braking in a straight line, the Type-S ABS system functions in the same three-channel mode as the 3.2 TL's. When the Type-S system senses high cornering forces, however, it automatically switches to a four-channel mode - allowing the ABS system to exploit the weight transfer to the outside of the turn and apply higher brake pressure to the outer rear wheel for enhanced braking performance.

VEHICLE STABILITY ASSIST (VSA) - (TL TYPE-S)
For enhanced control during acceleration, cornering, and sudden collision-avoidance maneuvers, the 3.2 TL Type-S is equipped with a standard Vehicle Stability Assist (VSA) system. Similar to the system first unveiled on the 2000 Acura 3.5 RL flagship sedan, the Type-S's VSA system enhances vehicle stability by applying brake force to either front wheel as necessary while managing the throttle and ignition systems.

Analyzing data that is constantly received from eight vehicle sensors, the VSA system compares the driver's control inputs with the vehicle's actual response. If the actual response is outside a predicted response range - as can happen when cornering forces exceed the tires' performance capabilities - VSA automatically intervenes with an appropriate corrective action. In the case of oversteer, VSA applies braking to the outside front wheel to counter the unintended yawing effect. If understeer is detected, VSA applies braking to the inside front wheel and reduces engine power to help bring the car back onto the driver's intended course.

The VSA system in the Type-S has been carefully calibrated to add handling stability and predictability without intruding on the process of spirited driving. Whenever the system is actively enhancing the vehicle's stability, an indicator light flashes on the instrument panel. In addition, VSA's stability enhancement and traction control can be disabled with a cockpit switch while still leaving the Anti-lock Braking system fully functional.

WHEELS AND TIRES
The 3.2 TL wears 6.5-inch wide by 16-inch diameter aluminum-alloy wheels and 205/60R16 Michelin MXV4 all-season tires.

The sportier Type-S receives larger diameter 17-inch by 6.5-inch wide aluminum alloy wheels shod with 215/50R17 V-rated, all-season, high-performance Michelin MXM4 tires for outstanding cornering capability.

The front end of the TL sports an aggressive grille, fenders and bumpers, Xenon High Intensity Discharge (HID) headlights, and integrated fog lights as standard. In the rear, a crisp break at the top of the rear panel lends a sporting edge.

In Fall of 2002, the TL will receive two new exterior colors with Desert Mist replacing Naples Gold and Royal Ruby replacing Firepepper Red.

PRECISE FIT AND FINISH
The world-class fit and finish of the TL is readily apparent at a brief glance or under the closest scrutiny. The TL's doors, for instance, are tuned with stiff structures, laser-welded door panel blanks, special plastic-encapsulated door checkers and latches, and generous sound damping materials - all of which combine to deliver a high-quality "thunk" when the doors are closed. Special power-window motors increase window speed and reduce noise, while the windows themselves are sealed with reliable sash-type door structures.

UNIT BODY STRUCTURE
For the best-possible ride, handling, and NVH control, the TL unit body was designed to provide maximum torsional and bending rigidity without adding excess weight.

Exceptional rigidity is achieved through the use of a high-strength cabin and ladder-type-subframe with large box-section rails and strategically placed reinforcements. This rigid structure allows the suspension mounting points to maintain a consistent position, resulting in improved handling precision, ride comfort and safety.

DOOR CONSTRUCTION
For enhanced weather sealing and reduced wind noise, the highly rigid door structures of the TL are designed with full-frame windows. By laser welding the door panels, steel panels of different thickness can be used in the door - allowing the designers to use the optimum steel thickness in each area for a strong yet lightweight door.

NOISE, VIBRATION, AND HARSHNESS (NVH)
To ensure a quiet ride, insulation materials have been incorporated into the doors and gap-filling foam seals all roof-pillar cavities. The TL utilizes triple door seals for reduced cabin noise while extensive insulation is incorporated into the rear wheel-house regions. The TL also utilizes a rigid steering-hanger beam, steering-column shaft and accelerator cable bracket for reduced steering wheel and throttle pedal vibration.

In addition, the outside rearview mirrors have also been shaped to pass cleanly through the air, reducing wind noise and contributing to an exceptionally quiet cabin environment.

XENON HIGH INTENSITY DISCHARGE (HID) HEADLIGHTS
For exceptionally clear visibility when driving at night, the TL Type-S is equipped with reflector-type Xenon High Intensity Discharge (HID) headlights. These premium headlights are three times as efficient as conventional halogen lamps (using less electrical energy) and produce nearly double the illumination and bulb life. The brilliant beam delivered by the Xenon headlights improves illumination by 45 percent on low beam (the TL uses conventional halogen high beams).

To prevent the battery drain that can occur if the headlights are accidentally left on, the TL is equipped with an auto-off feature that turns off the headlights 15 seconds after the driver's door is closed or the doors are locked.

ADVANCED MATERIAL TECHNOLOGY
The TL is crafted using an impressive array of sophisticated technologies and advanced materials, including:

Laser-welded inner door panel blanks for increased strength and decreased weight
High-gloss B-pillars with high scratch resistance
High-strength, dent-resistant steel doors
Side-door protectors and side-sill garnishes use a durable body-color film for greater chip and scratch resistance
Body-color roof molding
Lightweight, fiberglass hood insulator
Anti-acid-etch clear coat (dark colors)
Chrome-plated, injection-molded door handles
Two-thirds of plastic materials are polypropylene or polyethylene and are easily recyclable

WIND NOISE PERFORMANCE
To achieve low levels of wind noise, the designers of the TL relied upon extensive wind-tunnel development and computer simulations. The TL's body-panel shapes were carefully engineered to minimize wind noise, and the folding side-mirror shapes have been extensively refined to bring wind noise to ultra-low levels.

2003 Acura 3.2 TL - Interior

CABIN OVERVIEW
The spacious interior of the TL has been designed to be attentive to the needs of enthusiast drivers while also delivering maximum comfort and convenience. From rich leather seating to fine wood-patterned trim, the cabin exudes an ambiance of warmth and luxury. The instrument panel is outfitted with large, analog gauges and all essential controls are grouped within easy reach of the driver - making the TL cockpit an ideal environment for spirited driving.

The TL Type-S features its own cockpit theme with special trim materials for an enhanced feel of sportiness.

STYLING
In designing the TL cabin, the interior designers looked to Pacific Coast powerboats for their inspiration. Their muse can be readily seen in the sweeping, wraparound cockpit design and the purposeful instrument panel configuration. At the same time, the TL cabin offers a highly personalized flavor, with controls designed for rewarding tactile feedback and fine materials selected to enhance the inviting ambiance.

INTERIOR ROOMINESS
With 110.5 cubic feet of interior volume, the TL ranks as a midsize car - and one of the most spacious sedans in its class. To create this roomy, five-passenger cabin environment, engineers capitalized on the space efficiency provided by the TL's unit-body design and compact, multi-link rear suspension

SEATS
The standard power front seats of the TL are designed to provide both enduring comfort over long drives and secure support during spirited driving maneuvers. The stitching pattern of the U.S.-sourced leather was carefully planned to ensure that it remained comfortable during extended cruises. The wide, contoured seats incorporate dual-density backrests for a soothing and enveloping feel, and also include firm side bolsters to hold the driver and front passenger in place during high lateral-g cornering.

The driver's seat is eight-way power adjustable and linked to the 3.2 TL's keyless remote entry system. Linked by a memory system with the outside mirrors, it permits one of two preset configurations to be accessed at the touch of a button. The front passenger's seat is four-way adjustable.

The driver's seat includes a heated bottom cushion and backrest, while the passenger's seat offers a heated bottom cushion. Both front seats include 4-way adjustable headrests on the 3.2 TL and 2-way adjustable headrests on the TL Type-S. All five TL seating positions are equipped with three-point seat belts.

For enhanced ventilation and a sporty appearance, the seats in the Type-S are trimmed in perforated leather. The Type-S seats also feature deeper bolsters and added support for sporty driving.

INSTRUMENTATION
Keeping the driver informed at all times is a highly accurate, micro-processor-controlled instrument cluster with displays for engine speed, vehicle speed, outside air temperature, fuel level, dual trip meter, and secured door signal. The large tachometer face includes a bright LED digital display that indicates the current gear position when the transmission is in its semi-manual SportShift mode. Illuminated pointers on the analog instruments make the gauges easy to read regardless of the amount of light in the cabin. The TL Type-S includes a metallic-faced instrument cluster for a sportier cockpit look.

MATERIALS
All of the materials used inside the TL cabin were carefully selected to create an atmosphere of refinement and soothing luxury. The instrument panel and door armrests are made with a special molding process that creates a softer-feeling surface with a uniform surface grain. The sides of the center console are backed with soft foam to cushion the legs of the driver and the passenger. Wood-patterned accents on the door panel and edges of the console warm the look of the 3.2 TL interior.

AUTOMATIC CLIMATE CONTROL
For exceptional comfort and convenience, the TL is equipped with a state-of-the-art, high-capacity, Automatic Climate Control System. The system's large compressor and evaporator help provide extremely rapid cabin-temperature correction while adjustable rear seat vents positioned behind the center console help to cool the backseat quickly and efficiently. The TL's heater is equally effective and uses an aluminum heater core and the same quiet blower unit as the air conditioning unit.

Controls on the dash allow the system to be overridden manually. When equipped with the available DVD-based Acura Satellite-Linked Navigation System, the override controls for the Automatic Climate Control System are incorporated into the computer-controlled, touchscreen LCD monitor.

MICRON AIR FILTRATION SYSTEM
To help ensure a clean, pollutant-free cabin environment, the TL's automatic climate control system is complemented by a standard micron air-filtration system that traps dust and pollen particles as small as eight microns and bacteria as small as one micron.

ACURA SATELLITE-LINKED NAVIGATION SYSTEM
The DVD-based Acura Satellite-Linked Navigation System is available as the only factory-installed option on the fully equipped 2003 Acura TL. Like the similar system in the 3.5 RL flagship sedan, the TL's unit utilizes a bright, easy-to-read LCD color touchscreen display in the center dash, a Global Positioning Satellite (GPS) receiver, an on-board inertial guidance unit, and a DVD database to provide the driver with route and navigation guidance for millions of destinations across the continental United States.

Using GPS data received from orbiting satellites, plus information from the on-board inertial-guidance system, the Navigation System can determine the vehicle's precise location in seconds. Using the touchscreen display, the driver enters a destination and the Navigation System guides him there using clear audio voice cues and a detailed moving-map display. For exceptional convenience, the DVD database stores information on 3.7 million points of interest - including ATMs, service stations, movie theaters, restaurants, hotels, and more.

The large, 6-inch color LCD display in the dash offers picture-in-picture capability, so the driver can see both a detailed map and highlighted turning instructions simultaneously. The system can display the vehicle's current position at any time, while a balloon function allows the driver to summon the address of any location simply by selecting it on the map. The system can also search for a desired destination by phone number.

In addition to the moving-map display, the system highlights route directions with clear voice instructions. Eleven different volume settings are available, and for ease of use the system automatically mutes the audio system's front speakers whenever a voice instruction is given.

The DVD-ROM database includes mapping information for all freeway networks and every major metropolitan area in the United States. Updating the Navigation System is accomplished quickly and easily by simply changing DVD discs. Updated DVDs are published annually and are available through Acura for a nominal charge.

ONSTAR® IN-VEHICLE COMMUNICATIONS AND ASSISTANCE SERVICE
OnStar® is standard in all TL models fitted with the Acura Satellite-Linked Navigation System. Providing an extra level of security and convenience, OnStar can offer 24-hour emergency assistance, accident notification, airbag deployment notification, stolen vehicle tracking, door unlock command and vehicle tracking.

The OnStar activation button is located on the rearview mirror. Pressing the button provides quick access to a live OnStar advisor, any time day or night. Using input from orbiting GPS satellites, the OnStar advisor can easily pinpoint the location of the owner's vehicle to help provide assistance.

In the event of theft, subscribers need only contact the OnStar Center (after filing a police report) and provide a personal identification number. An OnStar advisor can then pinpoint the car and direct authorities to its exact location.

OnStar-equipped TLs come with a free one year subscription to the Safe and Sound Plan. In addition, TL owners can choose to upgrade (additional cost) to either the Directions and Connections Plan or the Luxury and Leisure Plan. The Directions and Connections Plan adds route support, online concierge and convenience services and ride assist. The Luxury and Leisure Plan adds personal concierge services and other benefits (Med-Net fee is also waved for the first year). The optional Personal-Calling Package, which includes wireless phone and "Virtual Advisor" Internet services, is available as part of both plans for an additional charge. The Luxury and Leisure Plan adds personal concierge services and other benefits.

PREMIUM ACURA/BOSE® MUSIC SYSTEM
For a car as sophisticated and luxurious as the TL, only the finest of audio systems was considered appropriate. Thus, the TL features a standard Acura/Bose® Music System custom-engineered to take maximum advantage of the unique acoustics of the TL cabin.

Using data from such advanced measuring tools as microphone-equipped mannequins, Bose engineers precisely located each of the system's five speakers for optimum fidelity. Bose equalization circuitry automatically maintains proper tonal balance at all times, yielding a natural, lifelike musical experience no matter which seating position the passenger occupies.

Anchoring this remarkable music system is a 9-inch Bose Neodymium woofer in the rear package shelf. Using a rare earth, neodymium iron boron magnet, this sophisticated speaker produces powerful, accurate bass and impressive output from a remarkably slim and compact package.

Complementing the Bose speaker array is a new 6-disc, in-dash CD changer that eliminates the need for a separate trunk-mounted changer unit or CD cartridges. Though similar in appearance to a conventional single-disc in-dash CD player, the Acura/Bose in-dash changer stores up to 6 compact discs behind the flush-mounted faceplate. Operating just like a conventional trunk-mounted unit, the Acura/Bose changer can automatically shuffle tracks within one CD at random and provides hours of uninterrupted listening pleasure. For maximum flexibility, the Acura/Bose head unit also includes a cassette deck. To allow the driver to remain focused on the road ahead, the radio stations, CD changer, and system volume can be conveniently operated using controls mounted on the steering wheel.

POWER GLASS MOONROOF
For those occasions when the driver wants to enjoy open-air driving, the TL includes a standard power operated glass moonroof that can be tilted-up or fully opened. The moonroof's trim, efficient packaging, with sliding sunshade, ensures that it does not infringe upon the TL's abundant headroom.

MULTIPLEX DATA BUS
The three separate CPUs in the TL-which control such functions as warning systems, intermittent wipers, and the auto-headlight system-communicate with each other via a multiplex data bus, which requires considerably less wiring and is more reliable than conventional systems.

KEYLESS REMOTE ENTRY SYSTEM WITH MEMORY FEATURE
A standard keyless remote entry system allows the driver and passenger doors to be unlocked by pressing a button on the key fob. A "panic button" on the keyless remote activates the security siren and flashes the headlights to summon assistance in an emergency. The keyless entry remotes also include a trunk-release button for easy access.

Two separate keyless remotes allow two different drivers to quickly customize the driving position to their preferred positions. When remote number one is pressed to unlock the door, the driver's seat will automatically reset itself to that driver's memorized seat position. Similarly, when remote number two is pressed, the driver's seat will automatically move to the second memory setting. The memory function may be turned off without affecting other remote entry system features.

TRUNK STORAGE
Thanks in large part to the compact dimensions of the TL's multi-link rear suspension, the trunk volume is an impressive 14.3 cubic feet. The trunk is designed with a wide opening and a low lift-over height for easy loading and unloading of cargo. To carry long items such as snow skis, the trunk features a lockable, flip-down pass-through door in the rear seat. Other trunk conveniences include a multiple-attachment cargo net, a jack and toolbox in a closed compartment, a storage compartment on the trunk's left side, an overhead hook for securing plastic grocery bags, and a tether with a hook that allows the trunk floor to be secured in the raised position for easy access to the spare tire.

2003 Acura 3.2 TL - Safety
OVERVIEW
Because passenger safety was of paramount importance in the creation of the TL, a comprehensive array of occupant-protection systems and features are included as standard equipment. The TL Type-S is equipped with a standard Acura Vehicle Stability Assist (VSA) system, which integrates the Traction Control System (TCS) and Anti-lock Braking System (ABS) functions with stability control to enhance driver control during sudden maneuvers.
Should an accident prove unavoidable, the TL is designed to protect its passengers with a sophisticated repertoire of safety technologies. Front and rear crumple zones, analyzed and developed on super-computers, are designed to deform progressively in an impact, helping to absorb and dissipate collision forces before they can intrude on the passenger compartment. Supplementing these and other structural systems are standard dual-stage, dual threshold front air bags and a driver's and front passenger's side air bag system.
ANTI-LOCK BRAKING SYSTEM (ABS)
The ABS system in the 3.2 TL is a three-channel design that modulates braking power to the front wheels independently and to the rear wheels in tandem - enhancing driver control during maximum-effort stops on slippery road surfaces.
The TL Type-S is fitted with a special four-channel ABS system that works in conjunction with the car's standard Vehicle Stability Assist (VSA) system. When braking in a straight line, the TL Type-S ABS system functions in the same three-channel mode as the 3.2 TL's. When the Type-S system senses high cornering forces, however, it automatically switches to a four-channel mode - allowing the ABS system to exploit the weight transfer to the outside of the vehicle in a turn and apply higher brake pressure to the outer rear wheel for enhanced braking performance and directional stability.
TRACTION CONTROL SYSTEM (TCS)
To enhance traction while increasing all-weather usability, the TL features a standard Traction Control System (TCS). Operating at vehicle speeds below 18 miles per hour, the system can apply one or both front brakes as necessary to control wheel spin. Because the system provides independent drive-wheel control, it also greatly enhances performance when accelerating on split-traction surfaces.
VEHICLE STABILITY ASSIST (VSA) SYSTEM
For enhanced driver control during hard cornering and accident-avoidance maneuvers, the TL Type-S is equipped with a standard Acura Vehicle Stability Assist (VSA) system similar to the system first unveiled in the 2000 model year on the 3.5 RL flagship sedan.
Integrating TCS, ABS, and stability enhancement processes, the VSA system constantly monitors eight vehicle sensors that compare the driver's control inputs with the vehicle's actual response. If the actual response falls outside a calculated response range - i.e., the vehicle is beginning to understeer severely - VSA automatically attempts to intervene with corrective action. In the case of understeer (where the vehicle continues in a straight line rather than turning), VSA applies braking to the inside front wheel and reduces engine power - helping to bring the car back onto the driver's intended line. In the event of oversteer (which can lead to a spin), VSA applies braking to the outside front wheel to counter the unintended yawing tendency.
Because driver control is so crucial to the enjoyment of a fine sporting automobile, the Acura VSA system has been carefully designed to add stability and handling poise without negating the car's dynamic responsiveness.
An indicator light on the instrument panel alerts the driver whenever the VSA system is actively enhancing the vehicle's stability. VSA can be disabled using a cockpit switch. The standard ABS system remains fully functional.
SAFETY STRUCTURE
From the very outset, the TL's "safety cage" was designed to provide the structural strength to meet safety regulations. Using super computers to simulate a variety of crash situations, engineers were able to study the impact forces on a "virtual car" to supplement their real-life prototype testing.
Among the innovations developed as a result of this testing are straight-section frame box rails with large cross-sections. In a frontal impact, these rails feed impact energy directly into the main frame structure - without the need for stiffeners at changes in cross-section.
Helping the TL exceed federal head-impact safety regulations are energy-absorbing roof-pillar garnishes and a roof lining designed to help reduce injury to passengers. To handle offset-impact energy, reinforcements are located at the roof side rails, the side sills, the A-pillars, and the front and side frame members.
For added protection in the event of a collision from the side, the B-pillars of the TL are stiffened, a substantial cross member runs transversely across the floor pan, a tubular brace connects the two A-pillars inside the instrument panel, a bulkhead is positioned at the back of the passenger cabin, and the rear doors are fitted with special catcher mechanisms to restrict intrusion into the passenger compartment. Each front door is equipped with twin side impact beams, while each rear door features a single beam. All four doors have a stamped-steel stiffening structure at the tops of the door panels, as well as impact-absorbing door-lining pads positioned near the occupants.
DUAL-STAGE, DUAL THRESHOLD FRONT AIRBAGS
The TL is equipped with dual-stage, dual-threshold airbags for the driver and front passenger. These airbags are designed to minimize the potential for airbag injury while providing head and chest protection for the occupants in the event of a collision.
The TL's front airbags can deploy at one of two rates depending on the severity of a crash. During a lower speed collision, the airbag inflators are triggered in sequence, resulting in slower overall airbag deployment with less initial force. During a higher speed collision, both inflators operate simultaneously for full, immediate inflation, to correspond with the greater impact force.
The driver's airbag is located in the steering wheel hub and the passenger's airbag is located on top of the dash. As in all Acura automobiles, the front passenger's airbag is designed to deploy upward toward the windshield and then back toward the occupant. This provides a large cushion to help protect the front passenger.
SIDE AIR BAG SYSTEM
The TL features seat-mounted side air bags for the driver and front seat passenger. The front passenger's seat is equipped with an innovative system designed to prevent injury to a small child or small-statured adult by preventing side air bag deployment if they lean into the side air bag deployment path. Seven sensors in the passenger seatback determine the height and position of the occupant to assist the system in determining if it is safe to deploy the side air bag. If the passenger is in the deployment path of the side air bag, the system will prevent the side air bag from inflating. When the passenger returns to an upright seating position, the side air bag will reactivate so it can deploy and protect the passenger in a side impact.
FRONT SEATBELT PRETENSIONERS
The TL is equipped with standard driver and front passenger seatbelt pretensioners. A device located in the seatbelt retractor mechanism tightens the seatbelt to help keep the occupant firmly in the seat - further enhancing the effectiveness of the seatbelts during a collision.
LOWER ANCHORS AND TETHERS FOR CHILDREN (LATCH) SYSTEM
The 2003 TL includes the Lower Anchors and Tethers for Children (LATCH) system on the rear seat. The LATCH system features ready-to-use attachment points at each of the three rear seating positions allowing compatible child safety seats to be installed without using the vehicle's seat belt system. Using the LATCH system, child seats may be attached in two separate configurations: one seat may be attached in the center seating position, or two seats may be attached concurrently, with one placed at each of the outboard positions. The LATCH system simplifies child seat installation when an owner installs a LATCH-compatible child seat.
XENON HIGH INTENSITY DISCHARGE (HID) HEADLIGHTS
For exceptional visibility when driving at night, the TL is equipped with standard reflector-type Xenon High Intensity Discharge (HID) headlights. These premium headlights are three times as efficient as conventional halogen lamps (using less electrical energy) and produce nearly twice the illumination and more than double the bulb life. The brilliant beam delivered by the Xenon headlights increases illumination by 45 percent on low beam (the TL uses the HID lamps and conventional halogen lamps for high beam illumination).
