Chevrolet Camaro SS
Camaro was welcomed back onto the highways, boulevards and cruise nights of America last year with enthusiasm. For 2011, the Camaro rolls on with evolutionary changes, including an increased horsepower rating for the 3.6L V-6 VVT – 312 (232 kW) vs. 2010’s 304 horsepower / 227 kW rating – while still offering an EPA-rated 29 mpg on the highway. 2011 models include several appearance packages. The RS package is available on LT and SS, and includes HID headlamps with integrated LED halo rings, a rear spoiler on LT, specific tail lamps and 20-inch wheels with a Midnight Silver painted finish.
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. It is standard on LS and LT models, producing 312 horsepower (232 kW) and 278 lb.-ft. of torque (370 Nm). Despite a compression ratio of 11.3:1, the 3.6L DI engine is designed to run on regular unleaded fuel. It is EPA-rated at 29 mpg on the highway.
Two 6.2L V-8 engines are offered in the Camaro SS, including the L99 on automatic-equipped vehicles and the LS3 on manual-equipped models. Both engines are derived from the LS3 that debuted on the 2008 Corvette, with an aluminum block (with cast iron cylinder liners) and aluminum cylinder heads. 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) and 420 lb.-ft. (569 Nm). Output on the L99 is lower than the LS3 because of a slightly 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 a six-speed automatic transmission.
An RS appearance package is available on LT and SS. It includes HID headlamps with integrated LED halo rings, a rear spoiler on LT, specific taillamps and 20-inch wheels with a Midnight Silver painted finish.
