Not all sports cars are rear-wheel drive, but many are. Rear-wheel drive is a popular drivetrain configuration for sports cars because it often provides better handling, balance, and weight distribution. With rear-wheel drive, the front wheels are free from the job of propelling the car forward, allowing for a more precise and responsive handling experience. However, there are also sports cars with front-wheel drive and all-wheel drive. Ultimately, the choice of drivetrain configuration for a sports car depends on various factors such as the intended use, performance goals, and driving preferences.
