For the kind of times we're talking here for many 4th Gens.... 12.0 - 15.0-second 1/4-miles, the difference between 0-60mph, and 1/4-mile time is a very consistent 8.5-seconds.... 5.5-sec 0-60/14.0-sec 1/4-mile, 4.0-sec 0-60/12.5-sec 1/4-mile. So 5.7-sec 0-60/14.2-sec 1/4-mile would seem to be what the typcial magazine road test would produce.
