An unusual type of engine made by Volkswagen Group in which two narrow-angle V-type engines are joined together with a common crankshaft.

VW’s W12 is two V6 engines placed side-by-side and joined at the bottom.

In this way they get even more cylinders into a very compact engine.

VW also had a W8 engine that was once fitted to the Passat and its W16 is fitted to the world’s fastest car, the Bugatti Veyron.
