Chevrolet has unveiled the 2010 Camaro sports car, resuming a 35-year production history that ran from 1967-2002. GM strove to strike a balance between performance and efficiency, and is offering the Camaro with a 3.6-liter V-6 direct injection engine delivering an estimated 26 mpg highway, and two V-8s, one of which offers Active Fuel Management (AFM, cylinder deactivation), for 23 mpg US. All engine options are matched with six-speed transmissions.

The 3.6L direct-injected V-6 in the LS and LT models employs variable valve timing to optimize performance and fuel economy across the rpm range. It is rated at an estimated 300 hp (224 kW) and 273 lb.-ft. of torque (370 Nm). A six-speed manual transmission is standard with the 3.6L engine; a Hydra-Matic 6L50 electronically controlled six-speed automatic, with TAPshift control, is available.
(For a historical—40 model years—comparison, the 1970 model year Camaro offered a base six-cylinder engine of 250 CID displacement (4.1 liters) that developed 155 hp. The new Camaro uses a smaller engine with almost twice the power output.)
The high-performance Camaro SS is equipped with a 6.2L V-8, with a choice of a six-speed manual or six-speed automatic transmission. Standard, manual transmission-equipped models receive the LS3 engine, estimated at 422 horsepower (315 kW) and 408 lb.-ft. of torque (553 Nm). The LS3 debuted on the 2008 Corvette and uses high-flow cylinder heads based on the Corvette Z06’s LS7 engine to enable high low-end torque and high-rpm power. It is paired with a TR6060 six-speed transmission.
A new, L99 V-8 engine is used on automatic transmission-equipped SS models. It is based on the LS3 and carries all of its high-performance design features, but also includes GM’s fuel-saving Active Fuel Management feature, enabling the engine to run on only four cylinders during light-load driving conditions, such as highway cruising, to improve fuel economy.
The V-8 is estimated at 400 horsepower (299 kW) and 395 lb.-ft. of torque (535 Nm); and it is matched with a Hydra-Matic 6L80 six-speed transmission. This combination delivers an estimated 23 mpg on the highway.
