The 1990 Pontiac Grand Prix was a mid-size coupe that represented a significant departure from the previous generation. Built on General Motors' new "W-Body" platform, the Grand Prix boasted a sleeker, more aerodynamic design and a host of new features. While still retaining the classic Grand Prix nameplate, the 1990 model offered a more modern and sophisticated driving experience. The interior was redesigned with a more driver-focused cockpit, featuring a new instrument cluster, redesigned seating, and improved ergonomics. The 1990 Grand Prix was available with a choice of two engines: a 3.1-liter V6 or a 3.8-liter V6. The 3.1-liter V6 produced 140 horsepower, while the 3.8-liter V6 delivered 160 horsepower. These engines were mated to a four-speed automatic transmission, and both the 2-door coupe and a 4-door sedan were offered.

The 1990 Pontiac Grand Prix was equipped with a wide array of standard features, including power steering, power brakes, air conditioning, and a four-speaker AM/FM stereo. Optional features included a sunroof, leather upholstery, and anti-lock brakes. The Grand Prix was praised for its comfortable ride, spacious interior, and powerful engine options. It was also lauded for its stylish design, particularly the coupe model, which was a popular choice among younger buyers. During its production run, the Grand Prix remained a popular mid-size car, particularly for its combination of performance, comfort, and affordability. A well-maintained 1990 Pontiac Grand Prix can still be found today, and its classic styling and smooth driving experience continue to evoke a sense of nostalgia for many car enthusiasts.
