There has been differentiation between the regular production street engine and the race powerplant for years. I wouldn't make the assumption that the DFI engine intro'd with the 997.2 was ever intended to replace the Mezger. It was designed primarily for the street car. If the info in this thread is correct, we're just now finding out about an engine worthy of the new GT3, and also what the Mezger's replacement will be.
Don't get me wrong - I would love it if Porsche built a new, state of the art, lightweight, efficient, middle finger to the accountants motorsport engine and then put something very similar into the GT3. But it doesn't look like they will.

Yes, but recall that every air-cooled 911 has a "Mezger" engine with a split-crankcase and direct ties to the racing cars. It's only a comparatively recent change in which the company realized that the standard engine wasn't up to the task of winning endurance races (1998).

Allow me to ask a question.
How many of you "paddle" haters have driven an SMG, DCT or PDK?
I can personally speak about the SMG III and DCT. They are fast and fricken fast respectably. They make a BMW awesome, well just imagine how much better Porsche can develop the R&D and develop a GT3/RS with the "paddles" so many of you appear to hate.

Why would they give you this information? What possible reason would they have?
Everyone is trying to find out the specs. on this car but they decided to tell you, just doesn't make sense.
I don't mean any offense it just doesn't make sense to me especially if they were higher up in the organization.

We'll all find out in March.

Can anyone explain to me the point of offering a manual option in the other 991 models, but not the GT3? No way they go from all manual to all PDk. Sure, initial car will be PDk for performance figures to justify price, and wow the world, and to sell cars to people who cant drive a stick, but there will be a manual option at some point, I don't care what some bigwigs at Daytona say........that is unless their master plan is to get all of us to switch to Carrera S models.....pure genius.
The street car will start to move away from Motorsport more and more, agreed on that point.

a: rosenbergendo is making all of this up.
b: the daytona guys were making all of this up.
c: the daytona guys were giving rosenbergendo straight scoop and he's passing it on to us.
Talk about making sense, a and b don't, to me. What would be the point of rosen jerking us around or them jerking him around? Call me crazy, I vote for c.

Virtually no one uses MT's in motorsport, and Porsche's high end competitors don't have them in their street cars anymore. If the presence of PDK, maybe even exclusively, in the new GT3 is your evidence that the street car is moving away from motorsport, I'd argue exactly the opposite. No one will be building new race cars with manual boxes. The "race bred" street GT3 is simply following the motorsport trend. My $.02.

We're only two months away from the launch so it's highly plausible that these folks are in the know, and don't care if a few thousand people on rennlist speculate on the final specification.

If Porsche ultimately starts using the new street car engine in motorsport and develops it in endurance racing, the divergence will be eliminated. Most track-junkie type buyers would just like to see the motorsport development happen first, and that doesn’t seem unreasonable to me.
BTW, as much as I love the Mezger, I don’t see any reason why Porsche can’t use modern tools such as DFI, CFD design SW, faster electronics, etc., to produce an outstanding new motor that beats the Mezger in every respect. In fact, I’m confident it’ll happen eventually, and probably soon. Exposure to the rigors of motorsport will be useful in exposing any weak links in the initial design. Can Porsche hit a home run on the first swing and build a bulletproof motor that holds up to repeated track use and doesn’t need any sorting on track? Maybe; time will tell. But I’d rather not be the early adopter who proves it one way or the other.

Is it just the picture or is that a horribly mangled FR wheel in the foremost car? I'm not digging this style of rims for one, and they're not standing up to mule duty either

People and companies leak information all the time. We see it in the stock market before major announcements come out. Sometimes companies (ie, Apple) use intentional leaks to create buzz.

Fair enough, as far as the transmission goes. But using an entirely different engine from the one they race represents a bigger divergence between race car and street car than past practice.

So if the rumors are true, we get the new street GT3 engine at about the same time that the motorsport guys get the race version. As you say, time will tell if that is a plus or not.
