[[File:Volkswagen W16.jpg|thumb|The Veyron's quad-turbocharged W16 engine]]

The Veyron features an 8.0-litre, quad-turbocharged, [[W16 engine|W16]] cylinder engine, equivalent to two narrow-angle [[V8 engine]]s bolted together. Each cylinder has [[multi-valve|four valves]] for a total of 64, but the configuration of each bank allows two [[overhead camshaft]]s to drive two banks of cylinders so only four camshafts are needed. The engine is fed by four [[turbocharger]]s and displaces {{convert|7993|cc|cid|1|lk=on|abbr=on}}, with a square {{convert|86|by|86|mm|in|2|abbr=on}} bore and stroke.
