Those numbers are pretty hard to believe. You guys don't think Porsche pulled a "Ferrari" do you? Those of you that know what that means...well...never mind.

Hope those numbers truly reflect what the customer cars are capable of.

Were the brakes PCCB's? Dunlops or Michelins?

Epic numbers

Great numbers but not unexpected if you look at the EVO magazine special feature. It was surprising there also to see the 991 GT3 in as delivered trim lighter than the 997.2 GT3 and 997.2 GT3RS.

As Ive been saying for some time I believe you will find this car is quite unbelievable on a track and numbers like this confirm what I was told by someone back in Nov.

Here are the in depth results laid up against prior years comparisons from one of the preiminent German car magazines which was published around 6 weeks ago. These tests are with tow passengers full tank of gas and are in metric so will differ somehwat from C/D figures (which by the way have generally been regarded from us non Americans as at least a tad optimistic!). I think the true value in the figures are the "comparative" values and what they tell us is that the 991 GT3 is both on road and track very comparable to the 2011 997.2 GT2RS. There is no competition on most performance metrics from any previous GT3 including the 4.0RS. The comparisons made the will be non empirical (i.e. driving feel, sound, experience).

3.6 secs 0-62mph (0-100kmph) looks more realistic and still very impressive.

Yes that is with an extra 100kg or 220lb above what Porsche test with (i.e. 1 extra male passenger and timiing gear with full tank). Hence it is 0.1s slower than factory time.

haha. Youre now banned by Porsche.
Only way out is to buy a 918!

To answer your question, the car that C & D tested had the following options: PCCB, sound package plus, sport chrono clock, guards red seatbelts, and telephone module. The tires were Michelin Pilot Sport Cup 2.

Every car magazine has their own testing procedures, as long as they are consistent between different cars. I would never compare objective numbers of the same car from different magazines.

Car and Driver consistently gets some of the lowest acceleration times in the industry, so take the results with that in mind.

Nonetheless, it seems the 991 GT3 is extemely fast (anything under 4 seconds for the sprint to 60-62mph is more than fast enough for me), and I think the PDK is a big part of it. One thing I do like about C & D is that they always do the rolling 5-60 mph test, which is much more repesentative of "real life" accelerating as fast as possible without launch control or manually launching the car by dropping the clutch at high revs. 5-60 mph in 3.9 seconds is DAMN fast for everyday pulling away from a stoplight.

Now I can't wait for Sport Auto to do their supertest on this car so we'll get an indpendent measure of the Ring and Hockenheim laptimes.

I agree that PDK is a big part of it, and I think that's a key reason they didn't offer manual - the numbers would have been significantly worse, and some people might have complained that the car's weaker than expected on the road. If you look at the torque curve, there's not much going on below 4,000 rpm and it builds steadily after that. When launch mode is used, IIRC PDK keeps the revs above 7,000 once 2nd gear is reached.

Since I'm NOT interested in drag racing these cars, I agree that 5-60 is more informative than 0-60, and I think 30-90 is even better.

Thanks PC, for the follow-up info. My copy of the mag will hopefully be here soon but in the meantime I was curious; what seats are in the test car? You don't list a seat option so can I assume it had standard seats, as opposed to a ROW model with the still unobtainable sport buckets?

GrantG

I did a calculation on the following website (assume driver weight is 173 pounds) and came up with 533 hp using the trap speed of 126mph and 480hp using 1/4 mile time of 11.2s. Averaged together you get 506.5hp (consistent with rumor that all motors are dyno'ing over 500hp):

That's some fast numbers.

Yeah very impressive - the quarter mile is within 0.2 seconds of the McLaren MP4-12C that C&D tested.

It just blows me away what Porsche can achieve from 3.8 naturally aspirated liters.

The braking is very impressive too...

70-0 testing with C&D:

12C - 145 feet
458 - 146 feet
2014 GT-R - 145 feet

They don't say. the pictures in the article show a red car with euro plates. The test was performed in Germany. They do show a pic of the sport bucket seats, but I recognize it as one of the original Porsche press pics. My guess is that the car they tested indeed had the sport bucket seats.
