There is something wrong with the clutched out of the air emissions figures.
They use the figures from the Supra (which has a higher output engine about 375-380 bhp - see car throttle) but that car is lighter than the Z4 which has lower figures.
The Mog being 400 kg lighter should have an effect on the emissions figures.
Don't give drag figures as an answer to the anomaly drag barely comes into it at legal speeds
