A true sports car is a performance car whose primary function is to provide driving pleasure, and to allow the driver to immerse himself in that experience and communicate with the road as directly as possible. Its purpose is pure and singleminded.
The idea of a sports car has always been the same and it will never change. The designs will change as times change. But the concept will always remain.
A true sports car is light, direct and does without the things that more pedestrian vehicles possess. It is often derived from a race car in some fashion. The car may be a direct variation of a race car. It may feature technology and design from a race car. Or the people who designed and developed it have a competition background. It has heritage.
The car rewards drivers who are skilled and able. All drivers are not created equal. Those who can best feel and understand the subtle messages of the machine are rewarded with the greatest satisfaction. A sports car is meant to be driven well quickly.
What Do Sports Cars Look Like? They turn your head, they get you interested. You know just from looking at them that they offer performance and excitement. They are not ordinary cars. Even when parked, a sports car gives the impression that it is in forward motion.
What A Sports Car Is Not: Heavy cars are not sports cars. Saloons, estates, 4x4s, and the like are not sports cars. No matter how much power they make, how well they corner, how quickly they can accelerate or stop, or how much they've been modified, they are not sports cars. They may be performance cars. They may have very impressive performance. But they can never be sports cars.
Thoroughbreds are horses. But not all horses are thoroughbreds.
