Chevrolet Camaro SS

The Design features
With a design that is very close to the original concept, the 2010 Chevrolet Camaro acknowledges its heritage from the first-generation Camaro, produced from 1967 through 1969. The two-door sports coupe features classic proportions over a 112.3-inch (2,852 mm) wheelbase. The overall length of the Chevrolet Camaro is 190.4 inches (4,836 mm); width and height are 75.5 inches (1,918 mm) and 54.2 inches (1,376 mm), respectively.
The long hood and short deck are pushed to the far corners of the muscular fender forms and a fast, 67-degree rake windshield contributes to aerodynamic performance that includes a 0.37 coefficient of drag (Cd) on V-6 models and a slightly sleeker 0.35 Cd on the V-8-powered SS model.

The Interior details
Inside the four-passenger cabin, a well-executed balance of heritage, modern design and attention to detail conveys simplicity and refinement with contemporary details in the cluster, switches, dials and lighting. An available ambient light package, for example, offers advanced LED light pipe technology, giving the cabin a distinctive glow.

Deep, recessed gauges, located in square housings outlined in chrome, give a nod to the classic Camaro interior. The instrument panel gauges include both speedometer and engine rpm, with a driver information center located between the large gauges - its readouts and features controlled via a stalk on the steering column. An optional, console-mounted gauge package includes oil pressure, oil temperature, volts and transmission fluid temperature. The gauge package is included on 2LT and 2SS models.
Cloth upholstery is standard and leather-appointed seats are included on 2LT and 2SS models. Four-way manual adjustment including fore/aft and up/down on the driver seat and two-way adjustment on the passenger seat is standard. Heated, leather-trimmed seats with driver six-way power adjustment are optional.

The models include a three-spoke steering wheel with manual tilt/telescope adjustment. Cruise control and rear defog also are standard, while a leather-wrapped steering wheel and shift knob; redundant steering wheel controls; Bluetooth and USB port are part of the available Driver Convenience and Connectivity package. Also included in the package is remote start on automatic transmission-equipped vehicles, as well as a personal device interface module for iPods.
Soon after production begins, customers will be able to order a short-throw Hurst shifter that provides quick, concise shifting.

The Chevrolet Camaro's entertainment systems include a single-CD radio with six speakers that is standard on LS, LT and SS models. A premium, 245-watt Boston Acoustics nine-speaker audio system can be ordered on 1LT and SS models. XM Satellite Radio is standard on all models.
All models also include power door locks and express up and down driver and passenger window. Cargo capacity can be increased with the standard fold-down rear seat. The capacity of the trunk is 11.3 cubic feet (320 liters).

The Safety
The Chevrolet Camaro offers a comprehensive system of safety features - starting with a robust body structure and integral safety cage around the passenger compartment. High-strength steel and ultra high-strength steels are used in key areas throughout the structure. Safety technologies also include:
* Driver and front passenger dual-stage air bags
* Driver and front passenger seat-mounted thorax side-impact air bags
* Head curtain side-impact air bags for front- and rear-seat occupants
* Front-seat safety belt load limiters and pretensioners
* A front passenger detection system that senses children and small-stature adults, and suppresses air bag deployment when appropriate.
In both doors, an interlock pin is utilized to prevent intrusion into the passenger compartment and adds stiffness to the door structure by engaging with a clevis bracket set into the rocker panel.

The Powertrains
When it comes to performance, the 2010 Chevrolet Camaro delivers in unexpected ways. An advanced 3.6L direct-injected V-6 with variable valve timing is standard on LS and LT models. It offers power and efficiency, with 304 horsepower (227 kW) and EPA-rated 29 mpg in highway driving.
The performance-oriented Chevrolet Camaro SS offers a pair of 6.2L V-8s, including one with Active Fuel Management that helps improve fuel economy by shutting down four cylinders during certain light-load driving conditions. That model delivers 25 mpg in EPA-rated highway fuel economy.

3.6L direct injection V-6
Chevrolet Camaro's 3.6L direct injection (DI) V-6 delivers more power through increased efficiency, while maintaining fuel economy and lowering emissions - including a 25-percent drop in cold-start hydrocarbon emissions. Direct injection optimizes fuel delivery to the combustion chamber by introducing fuel closer to the combustion chamber. The fuel injectors are located beneath the intake ports and fuel is injected directly into the cylinder. The result is better efficiency in the combustion process leading to increased fuel efficiency at part and full throttle.

The 3.6L DI engine produces 304 horsepower (227 kW) at 5,900 rpm and 273 lb.-ft. of torque (370 Nm) at 5,200 rpm. Its 60-degree cylinder block and cylinder heads are cast aluminum to help reduce mass. A forged steel crankshaft provides optimal strength in the bottom end. The cylinder heads include four valves per cylinder, with a dual overhead camshaft design incorporating infinitely variable cam phasing.
A full dual exhaust system, with dual catalytic converters, helps reduce back pressure for optimum power. It also helps the engine reach operating temperature quicker to help burn off cold-start emissions. And despite a compression ratio of 11.3:1, the 3.6L DI engine is designed to run on regular gas.

The Chevrolet Camaro SS's 6.2L powertrains
Two 6.2L V-8 engines are offered in the Chevrolet Camaro SS, including the new L99 on automatic-equipped vehicles and the LS3 on manual-equipped models. Both engines are derived from the LS3 that debuted on the 2008 Chevrolet Corvette.
The 90-degree V-8 includes an aluminum block (with cast iron cylinder liners) and aluminum cylinder heads. The bottom end of the engine includes a new structural cast aluminum oil pan, with an oil capacity of 8.9 quarts (8.5 liters), while the two-valve cylinder head design is based on race-proven airflow dynamics. The intake valves measure 2.16 inches (55 mm) and exhaust valves are 1.60 inches (40.5 mm) in diameter.
The 6.2L engines also use a roller lifter-style camshaft with 5-percent greater intake-side valve lift than the Corvette's LS3. It manages airflow that is channeled through an acoustically tuned intake manifold with a composite design that reduces runner-to-runner variation. The throttle bore diameter is 90 mm.
Horsepower for the L99 is 400 (298 kW) at 5,900 rpm and torque is 410 lb.-ft. (556 Nm) at 4,300 rpm. The LS3 develops 426 horsepower (318 kW) at 5,900 rpm and 420 lb.-ft. (569 Nm) at 4,600 rpm (all numbers are SAE certified). Output on the L99 is lower than the LS3 because of a slighter lower compression ratio (10.4:1 vs. 10.7:1) and design features of the Active Fuel Management System. The L99 is paired exclusively with an automatic transmission.
As with the 3.6L models, the SS models employ a full dual exhaust system, with two catalytic converters to reduce back pressure.

The Transmissions
All Chevrolet Camaro models can be equipped with either a six-speed manual or six-speed automatic transmission. The availability of a six-speed automatic transmission is a first for Chevrolet Camaro.
With the 3.6L engine is the Aisin AY6 six-speed manual. It features lower shift effort and shorter throws for easier shifting and "fun-to-drive" characteristics. A hydraulic clutch and self-adjusting mechanism eliminates the need for adjustments throughout the lifespan of the transmission.
Performance Algorithm Shifting (PAS) is included with the 6L50. It lets the electronic transmission controller override the automatic gear selection during high lateral acceleration maneuvers.

On SS models, the new Tremec TR 6060 six-speed manual is paired with the LS3. It is designed to handle the high torque characteristics of the engine, while providing shorter throws, smoother gear synchronization and greater overall shift feel with little or no vibration. Its specs include a solid 290 mm flywheel and single-plate clutch. The final drive ratio for LS3 vehicles is 3.45:1.
The highest-capacity automatic ever in a GM passenger car, the Hydra-Matic 6L80 six-speed automatic, is matched with the L99 engine. Like the 6L50 transmission, it features driver shift control and PAS. The final drive ratio on all automatic-equipped Chevrolet Camaro models is 3.27:1.

Rear suspension features include high lateral stiffness for handling via three lateral ball joints per side. A sub-frame at the rear is double-isolated to minimize vehicle body motions and dampen road imperfections. The FE2 with a manual transmission includes a spring rate of 53 Nm, with wheel travel at 115 mm, and employs a limited-slip differential. The FE3 rear axle uses a limited slip differential on both manual- and automatic-equipped models; and the rear spring rate is increased to 66 Nm and wheel travel is reduced to 100 mm. Coil-over shock absorbers are used in the rear with a decoupled, hollow stabilizer bar. FE2 includes a 21.7 x 3 mm rear bar, while the FE3's large bar measures 23 x 3 mm.
The axle halfshafts on all V-8 models and manual transmission-equipped V-6 models are 30 mm in diameter on the left side and 40 mm on the right side. This design feature helps reduce the oscillation of torque from side to side and reduces axle hop.

The Brakes
Front brakes for LS and LT models include single-piston calipers with 321 mm x 30 mm rotors. For long life, performance and consistent feel, organic, non-asbestos compounds are used with FE2 brakes. At the rear are vented rear discs measuring 315 mm x 30 mm, with a single-piston aluminum caliper.
The SS front brake package includes Brembo 355 mm x 32 mm vented rotors with four-piston aluminum calipers. Semi-metallic brake linings are used at all four corners on FE3 models for superior fade resistance and pedal feel. The rear brakes are vented Brembos measuring 365 mm x 28 mm, with aluminum four-piston calipers.

The Steering
The 2010 Camaro's precise rack-and-pinion steering gives great driver feedback and cornering confidence. The design includes the rack mounted forward of the front axle centerline that enhances handling and provides a stiffer system, while maintaining a degree of lateral force that helps vehicle stability during turn-in. It also benefits noise and vibration characteristics. The steering ratio is 16.1:1 on all models, with 2.5 turns lock-to-lock. The turning circle diameter for all wheel-and-tire combinations is 37.7 feet (11.5 meters).

The Chassis control systems
All Chevrolet Camaro models include a four-channel StabiliTrak electronic stability control system that incorporates anti-lock braking, traction control and an active braking system to control wheel slip, optimize traction and enhance stability in wet, snow-covered or icy roads.
All SS models have a competitive/sport mode that optimizes the electronic stability control system for competitive driving and track conditions. It provides a less governed level of stability control for expert driving on race tracks. The stability control system engages only in severe oversteer or extreme acceleration in this mode.
The New for Chevrolet Camaro SS models with a manual transmission is Performance Launch Control that is enabled in the competitive mode. It is designed to control wheel slip to an optimal level, allowing hard accelerations at launch to achieve maximum grip and vehicle acceleration.
Hydraulic brake assist also is standard on all models. The system activates during emergency braking by detecting the speed and force the driver applies to the brakes. Under certain conditions, the hydraulic brake assist may activate the ABS more quickly and easily than vehicles without the feature.
