Ford Mustang has a fastback body style.
A four door fastback body style.
Fastback is a form of automobile body characterised by a smoothly sloped back. Fastbacks can be two-door coupés or four-door sedans. There is no separate volume for the trunk area of the car.
The fastback can be visually confused with the hatchback or combi coupé, which has a rear door, instead of the fixed window and separate trunk of a fastback.
Fastbacks are often designed for dramatic impact, but the form is also an advantage in developing aerodynamic vehicles with a low drag coefficient.
