What is the Pontiac Grand Prix?
The Grand Prix began as Pontiac’s personal-luxury coupe and later became a midsize car. Its later generations included coupes and sedans, bringing a sporty style to a roomier everyday model. Pontiac was a General Motors marque with a distinctively performance-inspired identity.
The generations covered here ran from 1984 to 2008. The fifth generation used the rear-wheel-drive G-body platform. From the sixth generation onward, the Grand Prix used the front-wheel-drive W-body platform. The later generations were sedans, broadening the model’s role beyond its coupe roots.
Grand Prix generations
The fifth generation ran from 1984 to 1987 and used the G-body platform. The sixth generation, from 1988 to 1996, moved to the W-body. The seventh followed from 1997 to 2003, and the eighth from 2004 to 2008; both also used the W-body platform.
The move to the W-body brought a change to front-wheel drive and a midsize format. Later sedans kept a low, coupe-like look, while the range included a choice of engine sizes.

US EPA figures cover engines from 2.3 L to 5.7 L, including petrol and diesel versions. Canadian NRCan figures cover 3.1 L to 5.3 L petrol engines. The lowest listed US consumption is 10.7 L/100 km, and the best combined EPA rating is 22 MPG. Canada’s lowest listed figure is 11.1 L/100 km on the NRCan 5-cycle test.
The EPA and Canadian 5-cycle procedures differ, so figures from the two markets are not direct equivalents.
