If by dead start or rolling
If by dead start or rolling start that you mean including a 1-foot rollout, or not, it depends on the country of origin. In the U.S. all magazine recording of acceleration for the last 60-70 years has been done at a drag strip, which records acceleration starting when the tire breaks the starting beam. This results in a 0-60 time that is 0.1-0.3 seconds quicker than recording acceleration from zero rotation of the tires. And similarly European acceleration measurements record 0-100KPH, which translates to 0-62MPH, which again is a couple tenths of a second slower. So the combination of those two differences in measurement result in a slower comparative time using European measurement, but since all professional timing gear includes both measurements I think that automakers should all include both, just as they do for U.S. and metric measurements.
