The 1999 Pontiac Grand Prix

Pontiac's Wide Track Grand Prix, already one of the most powerful cars in the segment, has even more muscle for 1999.  Building a reputation as the sportiest car in the midsize segment, the Grand Prix makes its case even stronger in 1999 with more power in the normally aspirated 3.8-liter V6. Advancements in engine breathing technology increase the output of the 3.8-liter V8 up to 200 horsepower.

New low-restriction air induction components raise the output in the normally aspirated 3.8-liter V6 engine from 195 to 200. The 3800 engine is standard on

1999 Lineup
Grand Prix GT sedan and GT coupe and is available on the SE sedan. The 3.1 is standard on the Grand Prix SE sedan.

To further enhance Grand Prix's sporty image, the 1999 GT sedan and GT coupe will come standard with a rear decklid spoiler.

1999 Lineup
Grand Prix's 1999 lineup includes the SE sedan, GT coupe and sedan and GTP coupe and sedan. GTP models are equipped with a standard 240 horsepower supercharged 3800 V6 engine.

Full-Feature Traction Control
Performance features include a full-feature traction control system for Grand Prix GTP models with the 3.8-liter supercharged engine. Full feature traction control uses a combination of spark timing, fuel cutoff, transmission upshift and brake intervention to limit power output when sensors detect wheel spin. Pontiac's Enhanced Traction System (ETS), which is standard for the 1999 Grand Prix line, functions in a similar manner, but does not include brake intervention.

Wide Track
Grand Prix's distinctive styling incorporates an aggressive Wide Track stance and racy low profile roof line used by both coupes and sedans. This sleek exterior design imparts a sporty coupe look to SE, GT and GTP sedans and provides a stable, road-hugging feel, enhancing Grand Prix's outstanding handling characteristics.

New Colors
Grand Prix customers will find two new exterior colors on the 1999 color chart - Dark Bronzemist Metallic and Medium Gulf Blue Metallic.

New Customer-Focused Features
New interior amenities for 1999 include standard front door courtesy lamps, a standard six-speaker sound system, an available eight-speaker Bose® sound system and available OnStar Mobile Communications System.

Bose® Sound
A customized Bose® eight-speaker premium sound system is now standard on the Grand Prix. The performance of the Bose® sound system is incredibly pure and full because it is custom-designed to match the unique acoustic environment of the Grand Prix's interior. Another benefit of the system is the balanced spatial presentation of the sound. Like acoustics in a concert hall, all listeners hear a complete panorama of sound no matter where they sit.

OnStar
A dealer-installed option, OnStar integrates onboard advanced vehicle electronics with Global Positioning System (GPS) satellite technology and a hands-free, voice-activated cellular phone, linking the driver and the vehicle with the OnStar Center.
