Good reference. I have yet to see a quote for downshift times and the actual penalty for distant downshifts. I do suspect that BMW will improve on these numbers a bit, but then again if you have to wait for the blip, maybe it is irrelevant. Either way the 600 adn 900 ms times are simply limited by how fast the clutch and gear shift movements can occur. It would be interesting to compare these figures to SMG II downshifts. Anyone have that data?
