GTP models come equipped with a supercharged version of the 3800 V6 that makes a whopping 240 horsepower. Traction control works in conjunction with four-wheel antilock disc brakes, which include beefy rotors and state-of-the-art calipers for better stopping ability. Power is put through the front wheels via a standard four-speed, electronically controlled automatic transmission. The GTP gets a heavy-duty version that allows drivers to pick "normal" or "performance" shift modes.
