The Mazda MX-3 is a 2+2-seat, front-wheel drive coupé of a kammback design, manufactured and marketed by Mazda. It was introduced at the Geneva Auto Show in March 1991 and marketed until 1998.

A Kammback—also known as a Kamm tail or K-tail—is an automotive styling feature wherein the rear of the car slopes downwards before being abruptly cut off with a vertical or near-vertical surface. A Kammback reduces aerodynamic drag, thus improving efficiency and reducing fuel consumption, while maintaining a practical shape for a vehicle.
