caption_attribution_description: English: Various body mods on this limited production 1986 Pontiac Grand Prix 2+2 were to homologate the styling tweaks for NASCAR racers. A small number were built, all at Canada's St. Therese, Quebec, plant.
context_page_description: The Grand Prix is a line of automobiles produced by the Pontiac Division of General Motors from 1962 through 2002 for coupes and 1988–2008 for sedans. First introduced as part of Pontiac's full-size car model offering for the 1962 model year, the marque varied repeatedly in size, luxury, and performance during its lifespan. Among the changes were positioning in the personal luxury car market segment and mid-size car offering from the 2nd generation to the 5th generation for the sedan and from the 2nd generation to the 6th generation from the coupe; it returned to a full-size car from the 6th generation to the 7th generation for the sedan, positioned below the larger Bonneville in Pontiac's model lineup.
context_section_description: An updated taillight design with three sections was the only major change to the 1986 Grand Prix. A new 2+2 model was offered for homologation of an aerodynamic coupe body for NASCAR competition, like Chevrolet's 1986 Monte Carlo SS Aerocoupe. (Pontiac never used the term "Aerocoupe").  2+2-specific pieces are an aero nose, bubble rear glass and a fiberglass trunklid with integral spoiler. All 2+2 models came equipped with a corporate 305 cu in (5.0 L) four-barrel engine, the 200-4R four-speed automatic transmission and 3.08:1 rear axle ratio. They have a two-tone paint job with silver on top and gray on the bottom, with 2+2 decals and striping and 15x7 steel Rally II wheels.  Modestly successful on superspeedways, where its bulbous rear end earned it a nickname of "the whale", the 2+2 design was seriously flawed for street use. Since the enormous rear glass was fixed (not an opening hatch), it forced the adoption of a dramatically shortened trunk opening.  Although it had modest horsepower, benign handling and design compromises, there were only 1,118 Grand Prix 2+2s built in 1986 and dealers were able to ask 20 percent above the list price for this limited production version. The cars were all allotted to dealers in the Southeastern United States.
  While the 3.8 L V6 remained standard for the regular Grand Prix, a fuel-injected 4.3 L Chevrolet 90° V6 was added to the option list for models other than the 2+2. This engine was available with a three-speed or a four-speed automatic transmission.
