What Is It?
2005 Pontiac Grand Prix GXP
What's Special About It?
Following on the heels of the Bonneville GXP is Pontiac's first V8-powered Grand Prix in nearly two decades. The Grand Prix GXP is powered by a 5.3-liter, V8 engine that is estimated to produce 290 horsepower and make zero to 60 miles per hour in approximately 6 seconds. But not only does the Grand Prix GXP have a more powerful engine, it's also the first Pontiac to receive Displacement on Demand (DoD) technology, a system which can increase fuel economy by up to 12 percent. The GXP's new power plant is partnered with a four-speed electronically controlled transmission with a manual-shift feature for more spirited driving.
The Grand Prix GXP isn't just about increased power. The suspension has been tuned as well to offer a sportier ride with Bilstein gas-charged struts and higher-rate springs and reduced ride height. A four-wheel disc brake system with aluminum calipers, plus vented and cross-drilled front and rear rotors complete the performance brake upgrade.
A quick walk around the GXP proves that it's not your old girlfriend's car. The lowered Grand Prix gets a meaner look with new front and rear fascias with rocker panel extensions, and chrome-ringed grille inserts and lower air inlets in the front and more prominent exhaust pipes in the rear. The 18-inch polished aluminum wheels at each corner are wrapped in low-profile rubber.
What's Edmunds' Take?
Pontiac is working hard to build upon its role as General Motor's performance division, and increased power through its model lineup is certainly a respectable way to proceed. The Bonneville GXP currently makes up nearly 30 percent of all Bonneville sales, and if Pontiac can infuse the same life into the Grand Prix models, the Grand Prix may find a home with those who may have otherwise looked toward an import sedan instead. — Kelly Toepke
