We’ve already seen the new BMW M5 go up against some very fast machines, but how does it stack up next to a SEAT Arosa?

Yep, that didn’t come out right, because those who remember what an Arosa was can undoubtedly say that it was anything but fast.

Nevertheless, the example that you’re about to witness in a video shared by Autocar isn’t stock. In fact, its 2.0-liter diesel engine has been modified to the extremes, just like a lot of other things, to the point where it now pushes out 550PS (542hp / 404kW) and 881Nm (650lb-ft) of torque.

Power is channeled to the front wheels only, through a six-speed manual gearbox, and the tiny Spanish hatchback weighs just 800kg (1,764lbs). Under ideal conditions, it’s said to be able to sprint from 0 to 100km/h (0-62mph) in just a little over 2 seconds, and run the 1/4-mile in 11.5sec.

Okay, that’s very impressive, but then again, so is the new BMW M5. Aided by its twin-turbo 4.4-liter V8 engine, generating 600PS (592hp / 442kW) and 750Nm (553lb-ft) of torque, it takes only 3.4 seconds to cover the 0 to 100km/h (0-62mph) sprint.

Moreover, unlike its ad-hoc challenger, the new BMW M5 is the first of its kind to use an all-wheel drive system, although it’s not the xDrive that you’d find in the regular 5-Series, as it wears BMW M’s signature all over it.

But how does it look next to the heavily tuned SEAT Arosa? Only one way to find out.
