There is only one engine available on the Pontiac GTO -- a 6.0-liter V8 rated at 400 horsepower and 400 pound-feet of torque. The standard transmission is a four-speed overdrive automatic. All GTOs come with a limited-slip differential and traction control. On the street, the 2006 Pontiac GTO rides like a luxury car and is easy to drive on a daily basis. Call Lee for details.
