Underneath the hood is the latest evolution of Chevy's race-proven small-block V-8. The car's longitudinal all-aluminum 6.0-liter V-8 engine pumps 430 horsepower and 430 lbs.-ft. of torque. The engine is paired with a Hydra-Matic 4L65-E four-speed, rear-wheel-drive, electronically controlled automatic transmission. It also could be equipped with the fuel-saving Displacement on Demand technology, debuting on somein 2004 on some 2005 GM models, which shuts down half of the cylinders during most driving conditions and automatically and seamlessly reactivates them for more demanding conditions, such as brisk acceleration or load hauling.

The SS features sophisticated low-arm SLA suspension and independent rear suspension for high-performance driving. The chassis features driver-adjustable shocks to change the damping ratio. The SS driver can tune the chassis for a softer setting during the week and dial in more performance for track days on the weekend. To complete the performance package, the brakes are six-piston calipers with 14-inch rotors up front, and four-piston calipers with 14.45-inch rotors on the rear. To help make the SS friendlier for everyday driving, it also is equipped with active-traction control.
