Will be interesting to see how badly fuel economy is impacted. I think it is quite a bit more than most of use would think?

I know on the M cars, the rear bumper, trunk face and license plate will get covered with soot from the overly rich exhaust. But the M cars are already very cold to begin with, just a few degrees off their operation point, they go down hill fast and start to suffer.
