A G-Platform Chevrolet Monte Carlo, where it and its Pontiac, Oldsmobile, and Buick corporate siblings were used as each of these Divisions’ entry into NASCAR for a good portion of the 1980’s; located in the Town of Cutler, Ohio.

The General Motors G-Platform was aptly given its platform designation after the introduction of the Front-Wheel-Drive A/W-Platform in 1982, as the G-Platform was known as the A-Platform from its introduction as the relatively new concept of an Intermediate-sized Car in 1964, up until the early 1980’s, when the Front-Wheel-Drive A/W-Platform largely supplanted it.

After 1984, only the Personal Luxury Coupes (Monte Carlo, Grand Prix, Cutlass Supreme, and Regal), the Cutlass Salon Standard Coupe and Sedan, and the El Camino and Caballero Coupe Utilities were produced until 1987, when the W-Platform would totally supplant the G-Platform, and would be produced alongside the (now older) Front-Wheel-Drive A-Platform until 1996, when both the A and original W-Platforms would all be supplanted by a 2nd Generation W-Platform, in addition to the U-Platform for new age Family vehicles. The Front-Wheel-Drive A/W-Platform Station Wagons supplanted the G-Platform Station Wagons in 1984.

The 1979-1988 A/G-Platform were the last Mid-Size Cars produced by General Motors to be classified as ‘Intermediates’, and were the very last Intermediate/Mid-Size Platform produced by General Motors to have a Body on Frame configuration.
