The muscularly styled mid-size Pontiac Grand Prix, which shares platforms and powertrains with the Buick LaCrosse, comes powered in its standard form by a 200-horsepower 3.8-liter V-6 engine. The GTP model offers a supercharged 3.8 that generates a brisk 260 horsepower, and includes an enhanced traction control system. A four-speed, automatic transmission is included with both engines. Meanwhile, a new GXP model was added to the line at mid-year 2005 and comes with a potent 5.3-liter V-8 that generates 290 horsepower and 325 lb-ft of torque, This engine includes Displacement on Demand technology that enables it to sip up to 12 percent less petroleum by deactivating half of the engine's cylinders when they're not needed, such as at cruising speeds. A high-performance, four-speed automatic transmission allows aggressive manual gear changes via Formula-One racing style "TAPShift" controls on the steering wheel. Its sport-tuned suspension promises uncompromising handling prowess, with StabilTrak stability control included. For 2006, a number of interior updates are added for refinement's sake, and a newly offered Special Edition package on base and GT versions includes unique styling and new 17-inch wheels.
