These are the latest pictures of the 991 GT3 in testing (published online a few days ago on a European forum). Interestingly the front shot of the vehicle is totally without camouflage so we can now see what the car is likely to look like. Given the lack of camouflage one wonders if Porsche intend to unveil the car at the Paris Motor show on 29 September, although it is generally accepted the unveiling wont take place until the Geneva Auto Salon in March 2013? This is entirely possible as there will be a number of impressive new vehicles on show from competitors (McLaren will be there - their first show ever!). Perhaps the 991 Turbo will be unveiled in March?

Researching the web, reading forums and other article and interviews it would appear the spec is starting to become more clear. Price looks like MSRP could be 14-15% more than the outgoing 997.2 2010 GT3 - assuming of course that PDK is the only transmission option (typically a 4000 euro option on the 991S). Base price in Germany for the base spec 2010 GT3 was 98100 Euro + Sales Tax. Budget on 133,000 Euro including tax for base car with standard a/c + PDK.

Most popular options are still likely to be PSM2, Chrono plus and sport bucket seats I'm guessing.

This is my hunch for the launch specification. its going to be a game changer...
  • PDK only. This will be a "flappy paddle" system and will possibly have slightly tweaked software for the GT3.
  • 1360-1365 KG. Although the PDK transmission adds weight the new 991 construction reduces overall weight considerably.
  • 20" centre lock wheels. Standard brakes = steel.
  • Electronic steering gear will remain but may benefit from tweaks for GT3
  • 0-100 kmph time of 3.8-3.9 seconds assuming PDK mandatory tranny option.
  • Top speed estimated at 320 kmph
  • Ring time between 7.28-7.30 mins based on 991S time vs outgoing 997.2 GT3

All of the above IMHO of course! Any way you look at it the 991 GT3 looks like it will be a brilliant drive...
Thanks for the update. I'm wondering if 997.1 and 997.2 GT3 RS values will stabilize or possibly increase due to them being the last of the Mezger-engines cars? Post 2007/2008 speculators, the values have really come down steeply over the last few years. Having just bought one about a month ago, I am obviously biased to one outcome, and it's still amazing to see what a following they have across so many auto enthusiasts. What do you think???

Them being the last of the Mezger-engine cars isn't a fact -- it seems there's a good possibility that the 991 3RS could use it as well...

In regards to you owning one - you want Porsche to discontinue the Mezger simply to support the value of your car at the expense of the rest of the community?

Mezger engine or not... Porsche will keep making new cars with new technology... Previous gen cars will keep depreciating...

The prices on 996 and 997 GTx cars have seemed to increase over the past few months. I'm expecting/hoping that the prices will drop once the 991 GT3 comes out. I drove a friend's 997 GT2 today, and it was da bomb.

Exactly..

PS: history has shown us that since 996 introduction normal 911 engines were not that good anymore..this goes for the 996 and 997 ..now with the 997.2 and 991 also some issues have arisen. but we will see, however, the engine does not have any motorsport background.

Why do you think Porsche is using the Spyder engine for the 918? Why do you think Porsche is developping a new racing engine..?

If the 9A1 engine would be so good then they would have put it in the new CUP Car...but they didnt.

1+1 still equals 2..and there are no (engine) miracles. The Porsche Motosport future will not be done with the 9A1 engine...thats clear. Currently the Mezger engine is still used and this one will be replaced by a completely new engine in the mid-term (3-5 years).

Well, one more thing - I bet you in 3 years the 997.2 GT3 will still be worth more then a by then second hand first series 991 GT3. But its just my personal guess.

Look at 993 & 996 turbo...which one is more expensive? Irony of the story, the 996 turbo uses the better engine..

BGB Motorsport won the Rolex Grand Am Conti series championship with the 9A1 this year. Both BGB and Rum Bum racing used the 9A1 with out any engine issues....guess you didn't know that?

I was taking as a "fact" that the 911-based GT3/GT3 RS would not use the Mezger engine, so my response on being "biased" was related to wanting the values of the 997-based GT3/RS to increase or stabilize - nothing more or less bud.

What about ALMS or Le Mans or Nurburgring VLN?

Predecessors of the current Mezger engine (split case, water cooled heads, flat 6) have powered 14 of Porsche's 16 Le Mans winning cars, not to mention runners-up and class winners.

9A1? Zero.

Better because it's water-cooled? They're very similar otherwise (other than heads).

Hi Guest89,

Pretty tough statement but its nothing but the reality. Again, what is striking that some people sont want to understand why Porsche took the "GT1 engine block" for 2013 991 CUP..why not the 9A1 engine ?..,if it won Grand Am Rolex series..?

By the way, this Rolex Grand Am series also includes 24h race for the 9A1 engine?.

Hi Grant, well, the block is very similar..but heads, pistons, turbos, headers, intercoolers etc are different..the similarity is maybe in the end 20-30%..although I dont know exactly...993/996 turbo experts can probably tell us more..

No, it doesnt. In fact the longest they race is about 2-3 hours which is basically a sprint race. And they run 100 + whp less. BGB won with regular old pre 9A1 and 996 motors too. The series is not as demanding.

That being said, I figured they were keeping the higher performance version of the 9A1 under wraps but its starting to become more clear now. There is no high performance NA 9A1 yet.
