The VR5 engines are a family of petroleum fuelled Internal combustion engines developed by the Volkswagen Group and produced from 1997 to 2006[citation needed]. They are derived from the VR6 engine family,[1] also developed by Volkswagen, but with one fewer cylinders. The VR5 is highly compact, thanks to the narrower angle of 15° and a displacement of 2,324 cc (2.3 L; 141.8 cu in). The VR5 was the first production block to use five cylinders in a VR design with a 15-degree angle.
