The compact design is cheaper to manufacture, since only one cylinder head is required for all six cylinders, much like a traditional inline-6 engine. Volkswagen Group introduced the first VR6 engine in 1991 and VR6 engines remained in production until late 2024. [1] Volkswagen also produced a five-cylinder VR5 engine based on the VR6.
The cylinder-head circuit heats the cabin's interior. The exhaust manifold is integrated into the cylinder head, enabling the engine to warm up more quickly, in turn making heat available quickly for the passenger cabin. At high loads, the exhaust is cooled by the coolant, lowering fuel consumption.
[7] [8] At the other end of the scale, the 1922-1976 Lancia V4 engine and the 1991–present Volkswagen VR6 engine use V-angles as small as 10 degrees, along with a single cylinder head used by both banks of cylinders. The engine balance of a V12 engine is that of perfect primary and secondary balance.
A VR5 engine block houses two staggered rows of cylinders within a single, short and wide bank – one row of two cylinders and the other having three. This narrow-angle, single bank block makes the five cylinder engine as short as an inline three cylinder, while also having single inlet and exhaust manifolds.
A V6 engine is a six-cylinder piston engine where the cylinders and cylinder blocks share a common crankshaft and are arranged in a V configuration. A typical DOHC V6 engine, represented in AngeTheGreat's Engine Simulator. The first V6 engines were designed and produced independently by Marmon Motor Car Company, Deutz Gasmotoren Fabrik and ...

VR5 and VR6 engines are very compact and light, having a narrow V angle which allows a single cylinder block and cylinder head. These engines use a single cylinder head so are technically a straight engine with the name "VR" coming from the combination of German words “Verkürzt” and “Reihenmotor” meaning “shortened inline engine”.
