The W16 engine that Volkswagen Group uses in its Bugatti Veyron and Chiron has a displacement of 8.0 L (488 cu in) and four turbochargers. It is effectively two narrow-angle VR8 engines (based on the VR6 design) mated at an included angle of 90 degrees on a common crankshaft.
In 1916, a rotary valve W16 engine was built in France by Gaston Mougeotte.
The Jimenez Novia, a one-off sports car built in 1995, used a W16 engine with two crankshafts. Built by combining four Yamaha FZR1000 inline-four motorcycle engines, the engine has a displacement of 4.0 L (244 cu in), eight camshafts and five valves per cylinder, and produces 560 bhp (418 kW; 568 PS).
