What is a Monte Carlo SS Aerocoupe?
Quick Answer
The Monte Carlo SS Aerocoupe is a 1986-1987 SS with a smooth, sloped rear window and a shorter trunk, built to make the car more aerodynamic for NASCAR. Chevrolet built only about 200 in 1986 and around 6,000 in 1987, which makes the 1986 Aerocoupe the rare one.
The Aerocoupe was a homologation special.
Why it exists
To make the G-body Monte Carlo SS competitive on NASCAR superspeedways, Chevrolet replaced the formal rear window with a curved, fastback-style glass. The rules required a minimum number of street cars, so the Aerocoupe was born.
