The base powertrain in the next Camaro will include a 300-horsepower version of GM's impressive 3.6-liter direct-injected V6 coupled with a six-speed manual transmission. When combined with the available six-speed automatic transmission, Chevy claims the V6 will return 26 highway miles per gallon. Stepping up in price and performance, the SS model will offer two versions of a 6.2-liter V8. The version matched with the six-speed manual transmission produces 422 horsepower and 408 pound-feet of torque, while the one attached to the six-speed automatic transmission generates less power -- 400 horsepower and 395 pound-feet of torque -- but includes Active Fuel Management to help deliver estimated highway fuel economy of 23 mpg. In addition to the V8, the SS model is distinguished by more aggressive suspension, 20-inch wheels, Brembo brakes and a stability control system that includes a competitive/sport mode and, on manual-shift models, launch control.
