Richmond Hill, Ontario - in this bit of inspired film-making from BMW Canada, the new M4 Coupé drifts into literally uncharted territory on the 'Ultimate Racetrack'.

Sadly, BMW doesn't mention who created these breathtaking visuals but, as an illustration of superlative car control in a truly intimidating setting, the 'punchline' (actually a visual reveal) comes as a complete surprise.

Which is why we're not going to spoil it for you - watch the video and prepare to blow your mind.
