If you visit this week's Goodwood Festival of Speed in the UK, make sure you stop by Cummins' stand to check out this one-of-a-kind Austin Mini with a unique engine-swap. In case you didn't notice, there's a colossal engine sitting just behind the passenger compartment on the classic Mini's stretched platform.

Cummins, an independent maker of diesel engines, fitted its biggest powerplant on one of the smallest cars around. The QSK78 diesel engine, which is used to power mining industry dump trucks capable of carrying 360 tonnes, is a 78-liter, 18-cylinder monster with 12 turbochargers producing 3,500HP (take that Veyron) at 1,900 rpm and 10,157 lb-ft / 13,771Nm of peak torque at 1,500 rpm.

Weighing in at over 11 tonnes (24,912 lbs), the V18 unit measures an astonishing 3,327mm (131-in.) in length, 1,633mm (65.5-in.) in width and 2,429mm (95.6-in) in height.

 

Yeah, take that Bugatti!!!

 

The engine is the same size as a Bugatti....!!

What's the bore and stroke on this engine? What's the diameter of each piston?!!
