Mini diesel by Cummins – Click above to enlarge

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.

The Frankenstein-ain't-got-nothin'-on-me monstrosity was, according to Cummins, commissioned by a customer, but we can hardly image it being actually drivable, let alone certified for street use anywhere this side of the Persian Gulf. It'll be unveiled this week at the Goodwood Festival of Speed, where it's sure to be the most powerful – not to mention the strangest – vehicle on display. Press release after the jump.

3,500 BHP MINI – FROM CUMMINS! GOODWOOD'S ODDEST EXHIBIT UNVEILED

Visitors to this week's Goodwood Festival of Speed will have some amazing machinery on which to feast their eyes but none more unusual than the exhibit which greets them on the stand of Cummins, the world's largest independent maker of diesel engines.

The Cummins centrepiece emerged after a previous show when the company showed off its largest engine (and the largest diesel engine made in the UK). The QSK78 engine weighs in at over 11 tonnes and some wag asked if it could be fitted to his Mini.

Steve Nendick, Cummins' Communications Director - Europe, Middle East, Africa and CIS, takes up the story: "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. "We're certain that the Goodwood crowd will have difficulty believing what they are seeing", he said.

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 no less than 12 turbochargers to develop 3,500 bhp and getting on for 14,000 Nm of torque (the original Mini made do with just 80!).

      Oh cool! Now they're making a line of engine stands that look like old Mini Coopers!
      • 4 Years Ago
      You'd drain the fuel tank just starting it. In fact, I don't think it could hold enough fuel to crank the engine.

      Very novel concept though.

      "..and the driver of a classic mini was instantly killed by tourque steer"
        • 4 Years Ago
        Either that or vibration would kill him.

        They should put one of those on a Harley next.
        • 4 Years Ago
        Nevermind torque steer, think the whole car would twist and snap from all that torque generated.

      Bring it on Porsche

      The ultimate sleeper, If I could just hide the engine somehow!
      • 4 Years Ago
      Wow, even if it can support it's own weight (It has supports under it in that picture) I doubt those 12 inch tires would do any good steering or being able to handle any of that power.
      • 4 Years Ago
      Funny.
      • 4 Years Ago
      I'm pretty sure this thing can't hold up the weight of the engine. The giant slab and blocks under the car are probably holding it up. Then there is the little problem of the wheels, 10,000 lb ft of torque would probably melt the wheels along with the driveshaft.

      While cool it is kind of pointless if it can't run.

      Next can we have a Citroen 2CV powered by a nuclear reactor from a submarine???
        • 4 Years Ago
        Assuming that it could be hooked up, with peak torque at a whopping 1500 rpm, and peak hp is just shy of 2000 rpm, I'm sure a well-modulated right foot will save the tires. ;)

        @Tony: stalling a car is due to an incapable left foot; not lack of power. Being unable to select the correct gear for going up hills is also a magnificent example of poor driving.

        It's probably close to sitting on it's sump, also if you look just behind the rear window, you can see the crank pully, no belt to the rockford cluch mounted above, and on the rear there's no sign of a coupling off the fly-wheel, so just forshow, it may be a fully working engine, but more likely missing it's internals.

        @ rich

        what if he was in 1st gear? if there was a serious lack of power it is possible to stall even if you are a professional driver...
      • 4 Years Ago
      Can someone say muscle car?
      • 4 Years Ago
      Even if the brakes were as big as the wheels - that thing wouldn't stop from 5 mph in 100 metres! Not to mention the torque steer! Put your foot down in that and the car would wring itself out :)
      • 4 Years Ago
      Hey, Porsche, I hear Mini wants a rematch!
        • 4 Years Ago
        Speaking of Porsche, that is my impression of a 911, a dated pregnant roller skate with a lot of power........ and people who still go "gaga" over it.
      • 4 Years Ago
      OK, so this supports it's own weight, or not?
        • 4 Years Ago
        I dont even know if there is a transmission for these engines, they spin generators on those dump trucks, which power an electic motor in each wheel.
        • 4 Years Ago
        No it doesn't. There's blocks under the car to keep it up.
        Somehow AB is assuming this is a mobile vehicle. There's not even a tranny here. Never mind the fact that the crank isn't even inside the car.
        Funny stuff though. :)
        • 4 Years Ago
        Considering the engine weighs over 11 tons, I seriously doubt it.
