In automotive design, an RR, or rear-engine, rear-wheel-drive layout places both the engine and drive wheels at the rear of the vehicle. In contrast to the RMR layout, the center of mass of the engine is between the rear axle and the rear bumper. Although very common in transit buses and coaches due to the elimination of the drive shaft with low-floor buses, this layout has become increasingly rare in passenger cars.

A dune buggy — also known as a beach buggy — is a recreational off-road vehicle with large wheels, and wide tires, designed for use on sand dunes, beaches, off-road or desert recreation. The design is usually a topless vehicle with a rear-mounted engine. A dune buggy can be created by modifying an existing vehicle or custom-building a new vehicle.
