2012 Porsche 911 Laps Nurburgring in 7:40, Similar to 997 GT3

Car News, Nurburgring, Porsche "” By MR on October 15, 2011 at 1:19 pm "” No Comments


The brand new 2012 Porsche 911 (991) has been improved on numerous subjects, but track times were not released up to now. According to reports by Go Auto, the Carrera S managed to drive off 13 seconds of its old time round the famous Nurburgring Nordschleife.

The new 991 Carrera S set a time of 7:40 around the Green Hell, which makes it as fast as the GT3 track-focused version of the 997 generation it replaces. Quite humiliating if you just bought a GT3, but on the other hand a great future perspective with Turbo and GT3 models to be released over the upcoming years.

Just a small recap. The latest member of the Porsche family is powered by a direct injection 3.8 liter flat six which delivers 400hp and 440Nm of torque. Power is transferred to the rear wheels via a seven-speed manual transmission or the seven-speed Porsche Doppelkupplung (PDK), which improves the performance.

With the manual transmission, acceleration from nought to 100km/h is done in 4.5 seconds. The 911 Carrera S with PDK manages to accelerates to 100km/h in 4.3 seconds. Pressing the Sport Plus button on the optional Sport Chrono package cuts that to 4.1 seconds. The top speed is 304km/h.

Was reading something yesterday quoting 17sec quicker...a lot to do with "total lack of understeer" apparently (and I guess significant weight saving + extra power). Motoring press jury seems to be still out on the electric steering but, seems like it's going to be an amazing car no matter what. Just imagine what the 991 GT3 or Turbo will be like

....and just image what the price tag will be []

I'll have to wait....2nd hand one will make a nice 50th birthday present for me !!

It's electro-hydraulic isn't it? If that's the case, I can't see how it's likely to be any different. [8|]

Apologies, just repeating what I've read re the steering...no clue actually how this new system works ??

Does it still have a steering column or is it a kind of "fly-by-wire" approach ?? Being an IT professional, what happens "if computer says no" mid-corner [&:]

Can someone explain ??

All I can offer is the official dealer info, doesn't seem to be hydraulic at all, fingers crossed that it is as good as the factory PR claim although I am a bit sceptical of artificial 'feel' albeit any form of power steering has that by definition.
A bit cheeky to charge extra for power steering plus imho.

Electromechanical power steering
The new 911 Carrera models feature an electromechanical power steering system with variable steering ratios and
no hydraulic components. One of the advantages of this system is the energy saving. This is due to previous
hydraulic systems drawing power from the engine at all times "" irrespective of whether the car was travelling in a
straight line or not. The new system only draws energy when it is needed "" i.e. when steering inputs are being
made.
There are also new safety functions of this system. The driver receives controlled responses via the steering wheel
and negative or unnecessary interference is filtered out. An active return function automatically returns the steering
wheel to the centre position even at low speeds. Also, when braking on surfaces with differing grip levels on the
left and right side, the steering generates a steering impulse in the required direction so the driver can easily
stabilise the car and stay on the correct line.
The optional power steering plus provides speed-sensitive steering assistance for additional comfort. At high
speeds the steering feel is as per the normal system, whereas at speeds below 31mph the system gives greater
assistance which makes manoeuvres such as parking even easier.

Hi Peter,

Clever stuff! [8|] Thanks for explaining that. I had assumed it was just the pump that was electric.

Will be very interesting to actually drive one. [8D]

Thanks Peter !

Quick Google and I now found this doc (VW 2004..but guess Porsche system is similar) :-

http://vw.nate-online.com/techdocs/Electro-Mechanical%20Power%20Steering.pdf

When I first heard the term "Electric power steering", I honestly wondered initially whether with this system, the steering wheel was still mechanically connected to the front wheels...(Duh !!) [8|]

Thankfully, seems it still is []
