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.[1]

The most powerful version of this engine, installed in the Bugatti Bolide,[2] generates 1,361 kW (1,825 hp; 1,850 PS) at 7,000 rpm.[3][4]

At the 1999 Geneva Auto Salon, Bentley presented Hunaudières, a concept two-seated mid-engined car with an 8-litre W16 engine. The engine was the basis for the Bugatti Veyron.[5]

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.
