Once upon a time a McLaren 675LT tried to play tag with a Porsche 911 GT3 RS on Germany's vaunted and venerated Nürburgring Nordschleife, this is what happened:
It's utterly incredible to watch the Porsche turn in, square it off, and punch the after burners down the straight-ish bits. The Mac carries its corner speed better but just doesn't squirt out like the RS.

Then again the driver of the 675LT doesn't seem terribly stressed about the ordeal, with 166 more hp and 600 lbs. less to lug around, theoretically it should wipe the floor with the Teutonic treat.

But who cares who should win, this is what this car thing is all about...
