Of course, those AWD cars are helped immensely by the 1 ft rollout stat the magazines use because they launch so hard out of the hole they're going 5-6 mph in that first foot, so those quick 0-60 times are really actually like 6-60 times. Compared to a front engined RWD car that is probably only going 2-3 mph after 1 foot.
Anyway, I should have clarified - I meant the 580 hp 991 version Turbo S, per MotorTrend:
Our track results can vouch for the newfound potency and response. It reaches 60 mph in 2.5 seconds (reading that sentence aloud takes 2.5 seconds). It does the 0-100 run in six flat (not bad for a flat-six), and blasts from 0 to 100 mph and back in 9.7 seconds. It almost makes the Porsche's 10.5-second, 131.8-mph quarter-mile time anticlimactic.

Roll out is comes into play on a timed 1/4 mile track. Its the time it takes for the front tire to roll out of the beam to start the clock. Roll out is worth .1 to .2 reduction in ET. A car that runs a true 11.0 for instance will ET at least 10.9 . Thats why you stage as shallow as you can to increase roll out. ET is the only important factor, not MPH. Some Magazines show at .2 lower ET and note that is figured with the 1 foot roll out factor just to show and sell hype of low ETs
