Under the Hood

Available only with rear-wheel drive, the 3.6-liter V-6 engine produces 255 horsepower and 252 pounds-feet of torque. Cadillac's 4.6-liter Northstar V-8 generates 320 hp and 315 pounds-feet of torque and can work with either rear- or all-wheel-drive. All-wheel-drive models have a rear bias torque split. Both engines have variable valve timing and drive a five-speed-automatic transmission with Driver Shift Control for manually selected gear changes. Three final-drive ratios are available for V-8-powered models.
