A two-door vehicle, also known as a COUPE (5 letters), is a type of car with two doors and typically seating for two or four passengers. It is usually smaller than a sedan and has a sloping roofline that gives it a sporty look. Two-door vehicles are often used for racing and other performance activities due to their light weight and aerodynamic design. They are also popular for everyday use due to their compact size and fuel efficiency.
