The 5.7-liter LT1 V8 sends power through a 4L60E four-speed automatic transmission and limited-slip differential. SS-specific equipment includes 17-inch five-spoke alloy wheels, heavy-duty dampers, 12.1-inch disc brakes, and a one-inch-lower sport-tuned suspension. The gray leather cabin has front bucket seats with embroidered SS headrests, a center console, and a CD stereo.
