It's not a real wall y'know. More a CGI, digitally-enhanced, mostly fake wall. But you do get to see a BMW 1 Series M Coupe sliding around with an unhealthy disregard for its rear rubbers.
The 340bhp twin-turbo 3.0-litre straight-six - and that M3 rear differential - get a thorough workout in this video, posted by BMW Canada. We're not clear on its message, but it's definitely worth a watch.
TopGear magazine also gave the BMW 1 Series M Coupe a thorough workout. It's in this month's issue, so hurry and get a copy (if you haven't already).
