The W16 engine that Volkswagen Group uses in its Bugatti Veyron and Chiron has a displacement of 8.0 L (488 cu in) and fourturbochargers. 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 Bolide, generates 1,361 kW (1,825 hp; 1,850 PS) at 7,000 rpm.
Another concept car from Volkswagen Group to have the W16 engine is the Audi Rosemeyer, introduced in 2000 and shown at various auto salons. The engine fitted to Rosemeyer is the only W16 variation to have five valves per cylinder.
