The more powerful 3.6-liter engine that comes in the GXP is an overhead-cam engine with variable-valve timing rated at 252 hp and251 lb.-ft. of torque.
The automatic transmission worked flawlessly. The four-speed automatic is matched well to the engine's power and torque bands. The six-speed works better. Most of the time, we simply put it in Drive and drove. However, the automatic features a simple manual-control mechanism that allows the driver to shift manually. When the manual mode is selected, it will not automatically upshift for you at redline but will go right up against the rev limiter, a strategy many enthusiasts prefer. An indicator light in the instrument panel helps remind you to shift.
