Kelmark Engineering was an American automotive specialty shop established in 1969 and based in Okemos, Michigan. It focused on high-performance custom V8 drivetrain swaps, the modification and production of rear and mid-engined cars, and custom-built turn-key automobiles (the Kelmark GT). Until 1986, Kelmark Engineering manufactured kits and complete, finished, turn-key vehicles which were either Volkswagen-based or built on tubular race car-type frames. The outfit gained its name from Russ Keller and Randy Markham, the two co-creators who started the operation. Up until at least 1989, the Kelmark GT was still available as a kit albeit the manufacturer was Kelmark Motors in Holt, Michigan. The cars are all "rare" models, but the Volkswagen-powered Kelmark GT was the most popular.

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.
