What is the difference between a coupe and a roadster?

A coupe is a two-door car with a fixed roof and a sloping rear roofline that typically extends to the rear of the vehicle. It usually has seating for four passengers, although some coupes have only two seats. A roadster, on the other hand, is a two-door car with a convertible top and no fixed roof. It typically has seating for two passengers.

The main difference between a coupe and a roadster is the presence or absence of a fixed roof. A coupe's fixed roof provides added rigidity to the car's body, which can improve handling and stability. The lack of a fixed roof in a roadster means that the car may be less rigid and may not handle as well as a coupe.

Another difference between a coupe and a roadster is the type of driving experience they offer. A coupe provides a more enclosed driving experience, while a roadster provides an open-air driving experience with the ability to lower or raise the convertible top as desired.
