VR5 engine
The VR5 engines are a family of petroleum fuelled Internal combustion engines developed by the Volkswagen Group and produced from 1997 to 2006. They are derived from the VR6 engine family, also developed by Volkswagen, but with one less cylinder. 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.
