W16 engines are rarely produced, with the notable exception of the Volkswagen Group 8.0 WR16 engine that has been used since 2005 in the Bugatti Veyron, Bugatti Chiron and their related models.
Volkswagen Group produces a W16 engine, which has been used in the Bugatti Veyron and Bugatti Chiron since 2005. This engine 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.
The most powerful version of this engine, installed in the Bugatti Chiron Super Sport 300+, generates 1,177 kW (1,578 hp; 1,600 PS) at 7,000 rpm.
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).
