The British supercar gets up a real head of steam in new clip.

No McLaren is slow, but the 720S is comfortably the biggest, baddest 'mainstream' production car in the British brand's range. Naturally, it's well qualified for a flat-out run on the autobahn.

With 527kW/770Nm on tap from its twin-turbo 3.8-litre V8, it'll hit 100km/h in 2.9 seconds, 200km/h in 7.8 seconds and keeps pulling to 343km/h if given enough room. There's not quite enough room for this driver to nudge its V-max, but they get pretty close, touching 320km/h at one point.

That's faster than the M5 video we posted last week, and comfortably quicker than the Mercedes-Benz A200 managed. Natural rivals, those two.
