It’s no secret that the naturally aspirated 5.7L V8 LS1 gasoline engine, and all its corresponding offshoots, were a huge hit following the introduction of the 1997 C5 Corvette. Originally designed to work with RWD drivetrains, General Motors modified the LS1 extensively to fit the engine transversely for FWD applications in select GM vehicles. Today, one of these special vehicles – a 2006 Pontiac Grand Prix GXP – is currently listed for sale.
The highlight of this vehicle is undoubtedly the powerplant. Under the hood lies the naturally aspirated 5.3L V8 LS4 gasoline engine, which is rated at 303 horsepower and 323 pound-feet of torque. Highly adapted for FWD applications, output is routed to the front wheels via the GM four-speed automatic transmission.
It should come as no surprise that this unconventional drivetrain configuration is a recipe for heaps of torque steer.
Other performance-minded features of the Grand Prix GXP include a head-up display, vented- and cross-drilled brakes with PBR calipers, Bilstein performance-tuned gas-charged struts, Magnasteer II, and StabiliTrak dynamic control system.
The GXP physically differentiated itself from the Grand Prix lineup in various ways as well. Highlights include an aggressive front fascia, cooling vents on the front fenders, a unique rear bumper, and quad exhaust tips.
One of the more notable aspects of this Pontiac is the wheel setup. In fact, the front wheels are 18 inches by 8 inches, while the rear wheels are 18 inches by 7 inches. This allows the sporty GXP to wear 255/45R18 tires up front as compared to the 225/50R18 rubber out back.
With roughly 30,000 miles on the odometer, this 2006 Pontiac Grand Prix GXP certainly appears to be in great condition. So, what do you think? Is this interesting vehicle worth the $19,500 asking price? Let us know your thoughts in the comment section below!
