Car & Driver times for E0 and E1 SVT Contours:
0-60: E0 - 7.1 sec, E1 - 6.9 sec
1/4 mile: E0 - 15.4 sec, E1 - 15.4 sec
These are stock cars, of course, separated by nearly two years, with different drivers. Infer what you can about the numbers but with identical quarter mile times, I think the differences in an E0 and E1 are close to imperceptable in everyday driving.
