Cummins: the largest independent diesel engine manufacturer. The QSK78: the largest engine they make. Mini: one of the smallest cars on the road. Oh dear, this could get messy.
The unfathomably large QSK78 was recently unveiled with 78 liters of displacement, eighteen cylinders (that's 4.3 liters per cylinder!), a dozen turbochargers, 3,500 horsepower and over 10,000 lb-ft of torque. It's used to power those enormous dump trucks seen schlepping heavy loads (try 360 metric tons on for size) around quarries and mines. And now it's been installed in a vintage Austin Mini.
