The M3 final drive would have made it very short, though- a redline 2nd to 3rd shift would be at less than 60 mph instead of 73, and 80 mph cruising would be spinning 3500 rpm...
Exactly.

I think the key is the need to hit 60 in second. People tend to zero in on this number and put way to much emphasis on it. If the 1M required a shift to third, thereby skewing the 0-60 time relative to its competitors, people would be very disapointed.
