Fastback

A fastback is a body shape whose roof line slopes in one smooth line from the top of the cabin down to the rear of the car.

What is Fastback?

The shape helps aerodynamics and gives a sporty look. A fastback can open like a saloon boot or like a hatchback tailgate. Many coupés and some large saloons use a fastback roof. Some fastbacks have a hidden rear spoiler that rises at speed.

How it works

The gently sloping rear lets air flow off the car more smoothly, which can reduce drag.

Why it matters for your car

Headroom in the rear seats is reduced by the sloping roof. The shallow rear window can make it harder to see out when reversing.
