The Chevrolet SS returns this fall, after a 17-year absence. The Chevrolet SS is powered by the LS3 Chevrolet V-8, expected to deliver 415 horsepower and 415 lb-ft of torque. Also used in the 2013 Chevrolet Corvette, the LS3 displaces 6.2 liters, more than the 5.5-liter V-8 powering the Chevrolet SS NASCAR competitors.
The LS3 is married to a six-speed automatic transmission, which can be shifted manually using TAPshift paddles mounted on the steering wheel. With an aggressive 3.27 final-drive ratio, the Chevrolet SS accelerates from 0 to 60 mph in about five seconds – making it one of the quickest sedans on the market.
