Interesting that Guy, but as Gordon pointed out in that M2 vs Macan thread:

I think they may cock up their editing a bit. I'm sure thay take loads of footage of cars going around many times as well as many interior shots, then just splice it all together in the editing suite so it just "flows" regardless of whether its the accurate footage or not!
Still, why anyone would take an M3 to the track and drive it in Efficient at all .......
And 20mpg? Clearly not not done many laps when that was filmed!!!!
