NASCAR Homologation…(see definition below) that was all the rage in the late 60’s with the Daytona Superbird and the Ford Talledaga and once again in the late 80’s with the Chevrolet Monte Carlo SS Aerocoupe and this 1986 Pontiac Grand Prix 2+2 Aerocoupe. With the slick Ford Thunderbirds winning a majority of the races, Richard Petty spearheaded an effort with other drivers joining in demanding that GM design a car with a lower drag co-efficient so they could compete with Ford’s Thunderbird. In order to satisfy the homologation rules for the NASCAR series, GM built 1,118 Pontiac 2+2 Aerocoupes which were sold to the public; this enabled them to meet the production numbers NASCAR officials required for showroom stock model to be incorporated into the race cars.

Manufacturers wanted to spend as little as possible on this, which is why production numbers of these types of vehicles are so low. There were only 1,118 Grand Prix 2+2 Aerocoupes manufactured by Pontiac with a one year only run in 1986 and it went on to be a very successful design in NASCAR by reducing drag and increasing top speeds and helped put GM cars back in victory lane.

Homologation (from the verb homologate, meaning “to approve or confirm officially”) is the process of certifying or approving a product to indicate that it meets regulatory standards and specifications, such as safety and technical requirements.


Richard Petty’s Grand Prix 2+2 (watch for upcoming article)


Grand Prix 2+2 specific pieces are an aero nose, bubble rear glass and a fiberglass trunklid with integral spoiler. All 2+2 models were fully loaded and came equipped with a corporate 305 four barrel, 200-4R 4 speed automatic transmission and 3.08:1 rear axle ratio, 2 tone silver paint top with gray on bottom with 2+2 decals and striping, & 15X7 steel rally II wheels.

Unlike it’s G-body stablemates, the hot rodded Grand Prix was about as limp as they got. It wasn’t going to be anywhere near the turbo Regals or the decently snotty 442, but it wasn’t even on-par with the Monte Carlo SS’s 190 horsepower. The 2+2 made do with a 165 horsepower turd of a 305 hooked to the four-speed automatic and routed back to a standard GP’s axle ratio. It had absolutely no fangs whatsoever…even MotorWeek blasted the car’s lack of power.
