Fuel Economy Overview

The 1991 Pontiac Grand Prix achieves an EPA-estimated 21 MPG in combined city and highway driving, with 19 MPG in the city and 26 MPG on the highway. Powered by a 2.3L 4-cylinder engine paired with a automatic 3-spd, this midsize cars features Front-Wheel Drive drive.

In terms of environmental impact, the 1991 Grand Prix produces approximately 423 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this Grand Prix has higher-than-average emissions in this regard.

The estimated annual fuel cost for this vehicle is $2,850, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $3,500 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.

Aerodynamic Speed Penalty

EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Expect your real-world highway fuel economy to drop by roughly 15-20% at interstate speeds.

advisory

Component: ELECTRICAL SYSTEM:WIRING:FUSES AND CIRCUIT BREAKERS

THE FOG LAMPS, LOW BEAM HEADLAMPS, AND HIGH BEAM HEADLAMPS CAN BE OPERATED SIMULTANEOUSLY. THIS CAN CAUSE THE HEADLAMP CIRCUIT BREAKER TO OVERLOAD AND TRIP, RESULTING IN LOSS OF HEADLAMPS (LOW AND HIGH BEAM) AND FOG LIGHTS.

Consequence & Remedy

Consequence: LOSS OF HEADLAMPS WITHOUT PRIOR WARNING REDUCES DRIVERVISIBILITY IN INCLEMENT WEATHER CONDITIONS OR AT NIGHT, AND COULD RESULT IN AVEHICLE ACCIDENT. IN ADDITION, THE USE OF MORE THAN FOUR (4) WHITE LIGHTS ON AVEHICLE AT THE SAME TIME VIOLATES THE LAW IN SOME STATES.

Remedy: INSTALL NEW FOG LAMP RELAYS, NEW CIRCUIT BREAKERS AND NEW CIRCUIT BREAKER TERMINALS. ALSO, MODIFY THE LIGHTING CIRCUIT TO PREVENT THE FOG LAMPS AND HIGH BEAM LAMPS FROM OPERATING SIMULTANEOUSLY.
