All due respect, I don't know about the first point, but the the tire's grip on the road, suspension geometry, and the design of the steering assembly, power assist, etc. are going to determine how quickly the steering wheel can be rotated. The inertal effect of the steering wheel itself is, in comparison, almost infintesimal. Lotus may use a magnesium frame as part of overall weight reduction and as a gee whiz factor, but it won't let you turn the wheel faster in any way that will be meaningful or noticeable.

Just tweeted by Chris Harris:
The Mezger engine lives on! New 991 RSR and 991 Cup car will use the classic water-cooled, non-DFI motor.

Doesn't fly with homologation rules. Cups have to run the same platform as a street car in volume production or they wont qualify in FIA-GT and a number of other series...

NO customer cars for teams in 2013, DFI engine already "homologated" due to the fact it is in a street car.In addition to my earlier post my guess is will see a DFI engine for the RSR with sequential. Think fuel savings. Still Mezger for Cup 2013 only.
Homologation bodies such as Grand Am, WEC etc. have a "certain" flexibility to please and or meet the manufacturers wishes. Ask me how I know

Things are getting interesting now.
What's the latest on when the 991 GT3 will be announced/released?
I've had a deposit on one for 6 months and the possibility of a Mezger motor with a manual trans. is starting to drive me crazy.

Well, yes things are getting interesting now..I got the same info as Chris Harris..one week ago.lets sum up the facts:
1) 991 CUP and RSR will use Mezger engine probably for another 2-3 years..maybe more..but well see. The whole thing also depends on the regulations
2) Normal 997 GT3s - incl. RS, 4.0L etc, will be the last ones to use the race proven engine..expensive but good. It gives the 997 GT series another boost for future collectors items
3) The "looser" of all this is - for me - the 991 GT3. It will use an engine that is not worthy for it. How can this work? I heard that Porsche is maybe delaying a bit the intro of the 991 GT3 due to engine reliability..even if this were not true - Porsche itself gives you the answer which engine is better for racing.
Im really curios how many 997 GT3 owners will give back their GT3 in exchange for a new one..for me the question has already been answered months ago..

Extremely reliable source says November 2013, GT3's will begin to hit the ground. No word on possible order dates. Car will def be a 2014 model. No official word on PDK. BTW, I'm not so sure that the car pictured on this thread is a GT3. Looks like an S with the spoiler kit now offered.

I don't think there is any way Porsche can use the Mezger in the Cup and RSR and 9A1 in the GT3 for 2-3 years. There would be no way to homologate the motor unless using past motors doesn't count. But as far as I know the motor has to be in production to be raced. Which means the GT3 would have to use it as well.
