Video: BMW's ludicrous M Division diesels hit the track


So yesterday BMW announced the most insane diesel engine ever committed to road cars, via a press release. Today, in the tradition of the best PR, BMW has released a video, thus giving the engine two whole days' coverage.

If this engine were a three-cylinder diesel with less than 100g/km we wouldn't have bothered, but it's not. Three is the magic number - but that's because the engine is 3.0-litres big and has three, yes three, turbos.
Two little turbos are taken over by a big one, so it's the next logical step in BMW's existing twin-turbo engines, which use the smaller turbo at low revs for response then let the big one take over at higher velocity.

The step after that is to add another big turbo, but as this car already boasts 546lb f of torque and 381bhp, tyres may be at stake if that were the case; in the BMW M 550d, it gets the not-so-humble executive saloon to 62mph in 4.7 seconds - not far off the 4.4 of the actual M5. Yikes!

And all the while doing 44.8mpg. We know people with normal Ford Focii not getting anywhere near that.
