For the Golden Jubilee of Queen Elizabeth II, in 2002 Bentley Motors and Mulliner have created Bentley State Limousine, an official state car, used only on official engagements. In this serie were built only two four-ton armored vehicles, one of which as a gift to Her Majesty, while the second was commissioned by the crown as a back-up copy. Both limousines will be converted to run with biofuels.
