A sports car is a term use to describe a class of automobile. The exact definition varies, but generally it is used to refer to a low to ground, light weight vehicle with a powerful engine. Most vehicles referred to as sports cars are rear-wheel drive, have two seats, two doors, and are designed for more precise handling, acceleration, and aesthetics. A sports car's dominant considerations can be superior road handling, braking, maneuverability, low weight, and high power, rather than passenger space, comfort, and fuel economy.
