Looks like the 0-60 is about 3.25

1 foot rollout is the standard used by all major car magazines

That's only valid for 1/4 mile tests, it isn't the true 0-60 as measured by the OEM. The times with roll out are a lot more flattering!

all car mags post 0-60 mph with 1ft roll out

A lot of the US mags do, but the OEM's including Porsche don't. It's used in 1/4 mile to make up for the fact that you can't perfectly align the car with the starting beam. When measuring a speed delta there is no good reason for it, it just skews the results hugely. The above is a case in point - it's 8-60!

seems at least one US mag has got it right!

We believe the use of rollout for quarter-mile timed runs is appropriate, as this test is designed to represent an optimum drag strip run that a car owner can replicate at a drag strip. In the spirit of consistency, we also follow NHRA practice when calculating quarter-mile trap speed at the end of the run. So we publish the average speed over the final 66 feet of the quarter-mile run, even though our VBOX can tell us the instantaneous speed at the end of the 1,320-foot course, which is usually faster.

On the other hand, the use of rollout with 0-60 times is inappropriate in our view. For one, 0-60-mph acceleration is not a drag-racing convention. More important, it's called ZERO to 60 mph, not 3 or 4 mph to 60 mph, which is what you get when you apply rollout. While it is tempting to use rollout in order to make 0-60 acceleration look more impressive by 0.3 second, thereby hyping both the car's performance and the apparent skill of the test driver, we think it's cheating.

Ok then for you and Edmunds, I'm over 3 seconds. For everyone else, I'm under 2.8

0-100km/h in 3.2 sec.

what did you use to calculate the time?

here you go...

no idea why i cant post picture here?
