Pontiac Bonneville 1992-1999 Specifications

The 1992-1999 Pontiac Bonneville offered two main engine options: the 3.8L V6 naturally aspirated engine producing 170-205 horsepower and the 3.8L V6 supercharged engine producing 225-240 horsepower. The supercharged variant provided significantly higher torque and acceleration, making it the performance-oriented choice.

The Bonneville came equipped with a 4-speed automatic transmission (4T60-E) across all trim levels. This transmission featured electronic control for smoother shifts and improved fuel efficiency.

Standard safety features included dual front airbags, anti-lock brakes (ABS), and daytime running lights. Optional features included traction control and a driver-side airbag for later model years.

The Bonneville's fuel economy ranged from 18-20 mpg in the city and 27-29 mpg on the highway, which was competitive with other full-size sedans of the era, such as the Buick LeSabre and Oldsmobile Eighty-Eight.

Recommended maintenance includes oil changes every 3,000-5,000 miles, tire rotations every 6,000 miles, and major service inspections every 30,000 miles.

Notable features included leather upholstery, power-adjustable seats, a premium sound system, and optional features like a sunroof, heated seats, and a heads-up display in higher trims.

The Bonneville offered 16.6 cubic feet of trunk space and seating for up to six passengers, which was comparable to the Buick LeSabre and slightly larger than the Ford Taurus.

The Bonneville was not designed for towing, with a maximum payload capacity of approximately 1,000 lbs, making it suitable for light cargo only.
