Re: OFFICIAL: New 911 GT3 (991)
Guys, we already had some comparison runs 991 Turbo S (mine only) vs. GT3 and the GT3 wasn't even close. Only two different cars (GT3) but the differences were always huge, so don't get too excited. I really don't know how the italian car magazine came up with these numbers because they actually contradict everything I've read so far. Unless of course the car was in a very good shape but as far as I remember, the GT3 engines are quite steady in power output and to achieve these numbers, 500 hp wouldn't be enough, despite the lower weight of the GT3.
Btw: Autozeitung tested the GT3 at 0-100 kph in 3.3 seconds and 0-200 kph in 10.9 seconds, which are amazing results and the best results I ever saw in a German publication. AMS tested the GT3 in 3.6 and 12.1 seconds. In the same Autozeitung test (comparison), they tested the 991 Turbo S at 2.9 seconds and 0-200 kph in 9.6 seconds.
The GT3 did 100 to 200 kph in 7.6 seconds, while the Turbo S did 100 to 200 kph in 6.7 seconds (just for comparison, I measured mine at an average of 6.41 seconds with the performance box).
In the upper speed range over 200 kph, the GT3 is not even close to the Turbo S. Over 240 kph, the Turbo S builds full boost pressure almost up to Vmax.
According to rumors (I haven't seen any values yet), the 991 GT3 is slightly slower up to 300 kph than the 997 GT3 RS 4.0. So I guess the GT3 is somewhere around 42-43 seconds from 0-300 kph. Autobild Sportscars tested the Turbo S at 29.7 seconds, Sportauto at 31 or so as far as I remember. So there would be at least a 10 seconds gap between the GT3 and the Turbo S up to 300 kph. Based on these values, the 0-1000 m performance claim of the italian magazine seems quite confusing. For example: after 400 m (quarter mile), the Turbo S already hits 210-220 kph. So now imagine the speed after 1000 m. This is why these results in the italian magazine are impossible.
Also take the 0-400 m (quarter mile) time: The italian magazine stopped the Turbo S at over 11 seconds but there are already two videos on the internet which show a time of around 10.4 seconds, even the Turbo (non-S) does the quarter mile under 11 seconds. Something is wrong in this test.
Please don't misunderstand me, the GT3 is an amazing performer and in my opinion the best performance/value offer in the 911 family from Porsche. I just don't want people to get over-excited.
