The 6.0-liter W12 is a compact engine arrangement used in the Volkswagen / Audi AG vehicles, A8, Phaeton, and Continental GT and GTC. The "double-vee" arrangement allows for a small overall size in comparison with a tradition V- or Flat 12 engine. This engine made its debut in the 1999 Volkswagen W12 Nardo concept supercar. The arrangement is also used in the 4.0-liter W8 used in the 2004-2006 Volkswagen Passat and the 8.0-liter W16 of the Bugatti Veyron 16.4.
