I believe all American car mags use a one-foot rollout for 0-60 and 1/4 mile. The previous time of 4.1s for the DCT M3 was done this way, so this is comparable. I'm sure the difference is due more to environment, although I wonder how much different launch control is on the ZCP with its re-calibrated EDC and MDM. Note that 1/4 time is identical to previous tests of the M3. I really expected the Caddy to do better 0-60, but its power shows in the higher speeds.
And the M3 is more comfortable than the Caddy? What's this world coming to?
