It seems that most people think that there's minimal difference in acceleration between the 997 gen 2 Turbo and Turbo S, and with only 30bhp more on the S, I'd think they'd be similar too, but the claimed figures show 3.6 and 3.3 secs respectively which, at these warp-like levels is actually quite a difference.

On talking to a couple of dealers the other day (one OPC and one Indy), both told me that Porsche never quote 0-62mph acceleration figures which are superior to _deceleration_ figures (ie 62mph to zero). They say that the difference therefore is the Turbo S ceramic brakes which stop the car so much faster - hence allowing a faster acceleration "claim".

Anyone else heard the same ?

Not heard any of that but the real figure for the turbo S is more like 2.9 with the slow-coach standard turbo lagging a tenth or two behind.....

As above, Porsche are generally conservative with their quoted figures, they under promise and over deliver, the exact opposite of certain other manufacturers smile

As a 997 Turbo S owner (late 2012 car) I can say it is honestly hard to put into words how fast the car is!!

There are numerous independent tests both in this country and elsewhere on stock cars which show just over 2.9 seconds 0-60 mph using launch control (all Turbo S cars are pdk). The best I have seen is 2.88 seconds which is a test done in the US I believe. Go to YouTube and search 'the two second club' it's a test against a stock GTR and Veyron done on a track.

The 0-60 on the Turbo S is in the hypercar bracket, even above 60, the way it pulls to 100 mph and then keeps going relentlessly into jail sentence speeds is staggering. You would have to spend a truly massive amount of money to get a car that genuinely feels faster in real world conditions, imperfect road surfaces, etc etc.

In every day driving conditions the S does also feel a bit faster than standard Turbo (maybe more nimble is the right word, it's not a massive difference but it's noticeable for sure), exhaust note is slightly better. The overboost via sports chrono giving the extra torque is permanent on the S so you get the additional torque at all times not just the 30 extra bhp. Also, PCCB standard and they generally have a better spec in my experience so if anyone is wondering what to go for the Turbo S easily worth it- also is a limited run at 2000 produced for global market, probably 50% convertibles so coupe is really quite low numbers all things considered.

The Turbo S is PDK only. As such, the Turbo's time could be because it's a manual.

I doubt in the real world there is any difference; the main advantage is the Turbo S has a fantastic spec. It was cheaper to upgrade than spec a Turbo with the same options.

99% of gen 2 Turbo's (non S) are also PDK so the two figures quoted are a like for like comparison.

The 3.6 seconds figure for a standard Turbo IS for PDK, not manual, the 3.3 seconds 0-60 is for the Turbo S. Both figures are PDK, launch control (sports plus). The real 0-60 time for Turbo S is 2.9 seconds, or slightly over. Best recorded on a stock car in independent test is 2.88. At least that's the best that I have seen!

I have driven more than one example in both Turbo and Turbo S, (and own a Turbo S), there is a noticeable difference in performance (car just feels more alive, acceleration a touch more brutal!!), exhaust note is better, comes with PCCB obviously, better spec, and of course in the 997 the Turbo S is a limited run 2010-2012, 2000 produced for global market, half of which convertibles so good for residuals.

On the S the turbocharger vanes are modified, there is a carbon fibre air manifold, 516lb torque per ft continuous, not temporary overboost like on the standard Turbo. Max boost is 1.2 bar, the standard Turbo is less than that.

Here you go, all you need to know including a 2.7 0-60...

I thought that plenty of tests had shown that braking performing is not materially different with PCCBs versus standard brakes as a) the standard brakes are so good and b) the braking limitations are to do with tyre technology rather than scope of the brakes.

Further, although the PCCBs are lighter, this is probably more than offset by the extra goodies that come as standard on the Turbo S.

I'd have expected the main advantage of the PCCBs is in allowing the Turbo S to repeat the same stop times, time after time after time, with minimal fade. Probably not the case for the standard steel brakes.

They have great bite, which is probably why you imagine them to be better. You are right, ultimately tyres are the limitation. Worth noting the PCCBs also look fantastic...

I've seen a vid on YouTube where they race lots of supercars and a Turbo vs Turbo S made an interesting comparison over - i believe - a 2 mile sprint. The S was faster off the line, but it appearedto suffer from heat soak and the Turbo started to gain on it by the end.

Like i said before, the price difference is worthwhile purely for the spec.
