The type of drive train a car has can greatly affect its performance. Rear-wheel drive cars tend to have better acceleration and handling, while front-wheel drive cars have better traction and are more fuel efficient. All-wheel drive cars provide better traction in all weather conditions, but can be heavier and less fuel efficient. The size and power of the engine also play a role in a car's performance, as does the type of transmission, whether it's manual or automatic.
