We didn't include the Transit Supervan 1 of 1971, because technically it doesn't meet our requirements. Instead of an F1 engine, it had a motor inspired by the winner of the 24 Hours of Le Mans: the GT40.

However, its successor, born in 1984, uses a Cosworth 3.9 DFL engine, derived from the DFV from F1, which reached almost 600 hp (447 kW). Given that, it is not surprising that the bus exceeded 186 mph (300 kph).
