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. No changes were made to the Camaro powertrain to achieve the higher horsepower ratings for 2011. They are based on additional testing that demonstrated the Camaro’s air intake and exhaust systems are less restrictive than the similar 3.6L DI engine on which the original rating was based. 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. All Camaro models can be equipped with either a six-speed manual or six-speed automatic transmission. The Aisin AY6 six-speed manual is standard with the 3.6L engine, and a Hydra-Matic 6L50 six-speed automatic is optional. A Tremec TR 6060 six-speed manual is standard on the SS, and the Hydra-Matic 6L80 six-speed automatic is optional. Both automatic transmissions feature aggressive first gear ratios that deliver strong launches, but also provide tall overdrive ratios that decrease engine rpm and provide better fuel efficiency. Each also includes driver shift control, allowing the driver to take control via controls located on the steering wheel after selecting the “M” mode on the console-mounted shifter. Performance Algorithm Shifting (PAS) is included with the 6L50 and 6L80. It lets the electronic transmission controller override the automatic gear selection during high lateral acceleration maneuvers. The SS model’s Tremec TR 6060 six-speed manual is designed to handle the high torque characteristics of the LS3 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.
