The VR5 engine is a five-cylinder piston engine configuration developed by Volkswagen and produced from 1997 to 2006. The VR5 design is derived from the six-cylinder VR6, also developed by Volkswagen, but with the first cylinder removed. The VR5 is highly compact, with a narrow included angle of 15° and displacement of 2,324 cc (2.3 L; 141.8 cu in). This engine was referred to in some Volkswagen marketing materials as a V5, but this designation can also refer to a related configuration with two separate banks of cylinders, each with their own cylinder head.
