I just compare Motor Trend to Motor Trend and it's as apples to apples as you're gonna get. And if you compare across the magazines these days, you see very little variation. The testing methods appear to be a lot better than they were in years past, as it seems everyone is getting very similar numbers for the new 991.2 cars.

So I'd say your 4S is at least 3.3
The test data I saw said that the .2 4S clocked a tenth better than the 2S, not worse. Last I saw was 3.1 for the C2S and 3.0 for the C4S. I'd have to search for it, but IIRC it was Motor Trend.

Does porsche notably publish conservative numbers or what?

Anyone with a targa have any commentary about these cars being THAT quick!
They sure do move!

An easy way to look at it is:
Porsche - repeatable 0-60 under fair weather conditions using launch control
Magazine - best 0-60 time they could get in their own testing, may be corrected to a standard environment, may use a 1 ft rollout as discussed above - so in the end it becomes quite optimistic!

The best 0-60 you'll see in real life will probably lie between those numbers. You might do better at a drag strip.

I have to turn on my headlights at least a half hour before it gets dark or my Targa GTS will out run them.

Hope i can ask this question here as this is the closest thing to a targa discussion that i could find....
Im looking at hard top 991.2 and have driven stock Carrera as well as 991.1 GTS. Both are great but i think the steering on the .2 is better and the car feels more agile and responsive. (In Australia we pay double what you guys pay in north america BTW). GTS is a bit more "look at me" too. Anyway i love the look of the targa but am afraid that the weight and roof will affect handling which i think is top of my list. 1. handling 2. aesthetics 3. acceleration. Anyone help me out ? Cheers

Unless you plan to race the car it shouldn't matter. For me, the fun factor of having a targa trumps the extra pounds of the top adds. These cars are so fast already, no sane person would push the car to a limit that the extra weight would be a factor on the street anyway. Get the one you really want and don't let some magazine tester sway your choice based his track day review.

Yep, how many 911 owners will take their cars to a dragstrip? To me a much better measure of a car's street performance is how fast it is from 30 - 70 MPH or some other rolling metric. Just because a car has an extraordinarily fast 0-60 because of a computerized launch control and AWD, doesn't mean that it will necessarily have a similar performance when the car is rolling. For example a C7 Z06 with a MT will do a 0-60 in around the same time as some have listed for the 991.2, but from a roll the Z06 will walk away from a 991.2.
So if you want to play with a Z06, do it from a dead stop.

The drag strip is also relevant for that though; i.e., the trap speed

Exactly right. According to Car and Driver tests, if you compare 30-130 times--a more useful range for real-world performance--here's how a 991.2 base Carrera with a manual compares to some other recent Porsches:

991.2 C2 M7--30-130 mph--13.4 seconds
991.1 C2 M7--15.7 seconds
993 Turbo--15.8 seconds
993 Turbo S--14.4 seconds
996 Turbo--14.0 seconds
997.1 Turbo--13.1 seconds
997.2 Turbo--9.8 seconds

So the current base Carrera is quicker than everything up to a 997.1 Turbo.



Quick Reply: 991.2 targa 0-60 times - what's more accurate?
