V5 engine
From Wikipedia, the free encyclopedia
- For other uses see V5 (disambiguation)
The V5 engine is a V form engine with five cylinders.
Volkswagen introduced the first V5 engine, though this engine is not a true twin-bank V engine, but rather a VR5, or staggered bank straight five engine, and therefore not a true V5.
A V5 engine is impossible to construct, as there is no cylinder to counterbalance the last cylinder of the opposing bank, if each cyliner is to share a crankshaft throw.
It should be noted that the Volkswagen engine does not have a true V-configuration per se; it does not have one cylinder bank with 2 cylinders and one with 3; rather, it has all 5 cylinders sharing a single bank. The engine is derived from the VR6, and is thus a staggered 5, and has much in common with Volkswagen's earlier straight 5 developed in the 1980's for the Passat and Audi Quattro.
Volkswagen's VR5 is a 2.3 litre gasoline engine descending directly from the older VR6 from which VW removed a cylinder creating the first block to use five cylinders in a V design. The first version, with 2.3 L capacity, was capable of 150 PS (148 hp/110 kW) and had a maximum torque of 209 N·m (154 ft·lbf). It was introduced in the Passat in 1997, and later in the Golf and Bora in 1999. In 2000 the head was updated with twin cams, and was blessed with 20 variable timed valves raising power to 170bhp.
Honda used a V5 in its MotoGP race bike, the RC211V for the 2002-2006 seasons. This is a 990 cc engine with an angle of 75.5 degrees.
