So, the RS is getting a totally new engine?
I am struggling to understand why they went to all of that bother with the 'motorsport' 9A1 in the GT3?
They must have known at the time. Why didnt they just put the Mezger in it?
Wierd.
Don't think the Mezger can meet current emissions needs...I am struggling to understand why they went to all of that bother with the 'motorsport' 9A1 in the GT3?

For all that the autoexpress article is saying that Hatz confirmed the 'brand new engine', there actually isn't a single direct quote from him about that either..... Really wonder if Frankel is being slightly disingenous with the new unrelated engine bit just because it's a larger displacement 9a1 gt3 engine, which was also mostly claimed to be a 'new' engine if i remember correctly at the time.
If it truly is an engine completely different from the gt3, where does that leave the 991 gt3 then, excellent car as it undoubtedly is as the only gt3 never to have had the motorsport engine?

My guess is that this may be the engine that they stick into the homologated Cup S that races in GT3 since the regs in GT3 are emissions based I believe so Porsche can't use the default M engine - which of course will stay in the RSR ( GT2 )and the Cup car until presumably the GT3 engine proves itself as competition viable. Porsche need something positive to come from this car In competition terms. The performance gains on the 991 GT3 road car over the previous model are electronic and transmission based. The 991 platform is proving no quicker in Carrera cup than the 997 - which only serves to highlight the potential of the 997 road car was never really realised and the effectiveness of the electronic and transmission systems on the 991 road car. Stick the same power and transmission packages into the 997 and the 991 on the race track ( which is basically what has happened in Carrera cup) and there's very little or nothing in it.
For road going super cars, the future is now all about electronic driving aids and transmissions thus taking them in a very different direction to their racing equivalents.
Quite how Porsche manage this dilemma with the Forthcoming RS will be interesting.

You raise many good points....Quite how Porsche manage this dilemma with the Forthcoming RS will be interesting.
but does it matter that much if cars are seen as investments and few of the RS's will see more than 50% of their potential exploited?

Am really surprised by that about the 991 cup not being quicker vs 997 cup. I had heard the 991 cup was very different to drive and generally a lot easier to drive quick relative to the older car but had always assumed the newer gen car would be ultimately a faster car just from standard development (wider tyres, longer wheelbase etc). Do you reckon that is simply an experience/numbers issue so far or the platform simply isn't that much faster, if at all? It's very early in the 991 cycle vs 7 years of getting the 997s spot on for the various race teams and i guess a fair few haven't made the switch yet so perhaps that has had an impact.Apologies , I've had brain fade - parr for the course! - the CupS races in the GT3 catagory not GT4. Have edited my post to correct.
Yes, the 991 is a lot easier to drive. You don't have to work it to the apex as much and the gearbox now has much less chance of error. But it's just not quicker. Expect to see some damper/tyre spec changes for 2015. It's not that the platform is new, it's the 2nd season of racing it and there is no 997 option now.

That is surprising that its not quicker given its supposed to be significantly lighter with the aluminium replacing steel in the shell.Yes, the 991 is a lot easier to drive.

I would imagine that theres a minimum weight limit.
