We've Cummins to thank for the spectacle because aside from being the world's largest independent maker of diesel engines, they also appear to have a sense of humour.
The exhibit was conceived after a previous event when the company showed off its largest engine (and the largest diesel engine made in the UK), and some wag asked if it could be fitted to his Mini.
The QSK78 engine weighs in at over 11 tonnes and is er, quite large, so an extended wheelbase and supercar-style mid-mounted application was the only option.
"We never like to let a challenge go by unanswered so we got to thinking maybe we could fit the QSK78 into an original Austin Mini. It proved to be a bit tricky to fit under the bonnet but our engineers came up with a more creative solution," says Steve Nendick, Cummins' spokesman.
The QSK78, which is used to power mining industry dump trucks capable of carrying 360 tonnes, is a V18 monster with a capacity of 78 litres and uses 12 turbochargers (count 'em!) to develop 3500bhp and around 10,300lb ft of torque.
