Default 991.2 closer to 992 than 991.1?

I have been reading articles on the 991.2 and it just seems to me that mechanically it is one of the biggest refreshes of any 911 yet. Could it be that Porsche was just trying out most of their new technology before the big visual changes coming with the 992. Isn't it likely that mechanically the 991.2 will be more like the 992 than the 991.1? I'm curious what folks have heard or think will be mechanically different in the 992. Maybe us 991.2 folks are just guinea pigs for how well the the changes will be received by the public.

For example 997.2 steering wheel was also in 991.1. There is crossover of parts to some degree.

The 991.1 used the 997.2's engine (with only minor tweaks).

The 992 is an all-new platform and in my opinion the drive train does not = 50% of the car. Plus I thought I read that the 992 will have a new 8-speed PDK, similar to what the Panamera got.

For the engine it seemed obvious from the start that the 991.2 was a beta tester for the next gen., what a huge change for a couple of years production. And I get the feeling that the test results are good, coming from a screaming V8 NA car I've found this turbo better than expected.

Well for starters refreshes are mid-run and mostly cosmetic. 991 to 992 is a model iteration. Not a refresh. Granted, most customers know nothing of the engineering that is at the heart of these cars but catch every meaningless bead and bauble, which is why Porsche does the refreshes. For example, you got people talking about the steering wheel. So the 991 is not much different. Because, steering wheel. In reality the 991 has larger wheels, the first time in over 50 (60?) years Porsche increased wheel diameter from 24"; a wider by over 1" front track; a longer by over 3" wheelbase; and a whole new lower/wider body. With lots of new materials. And, for the first time in several decades, no sunroof.

Now those are some major mechanical changes. Still, nowhere near going from a venerated air-cooled engine to an all-new water-cooled motor, all-new body, interior, and suspension, like they did with the 996.

So all things considered you could probably say the 992 is one of the 3 or 4 (or 5) biggest model evolutions. In other words, about average.

Increased wheel diameter from 24"?

Technically its the rolling diameter or rolling radius. I used wheel deliberately to see if anyone would notice. Because I'm pretty sure almost everyone thinks it was just another "plus sizing" where the wheel gets bigger but the profile lower resulting in the same overall diameter. That's what they did for 60 years. That's not what they did with the 991. They didn't plus size. They upsized. Then they did it again on the GT3 and RS. This is a big deal. Unlike all previous changes going to the bigger wheel changes the whole dynamics of the car. But not obviously like the steering wheel. So nobody ever mentions it. Even though it is as big a deal as the engine moved forward, steeper windshield rake, oh gosh that's a couple more reasons the 991 was one of the most evolutionary 911 iterations ever.

And it seems like you think it's a good change. I'm not so sure. It might be a great engineering feat but for me, huge wheels make the car look funny.

I would like to know details about all new platform, especially the drive train comment. How it will be that much different than the 991.2.

i can only guess, the added ratio would get slightly quicker acceleration times? 7th and 8th would be overdrive instead of 6th and 7th now, which gives an additional gear in sports plus mode. i believe the car currently goes only upto the 5th in sports plus.

The answer is no, the 991.2 is a lot closer to the .1 than the 992. Yes, the engine is different. The gearboxes are the same, slightly modified. The chassis is the same, with minor tweaks. The interior is the same, with a new head unit and steering wheel. The body is the same. The seats are the same. And so on.

The 992 is a completely different body. The interior is completely different. The seats will be different. Etc. Powertrain will naturally be a continuation of the 3.0 TT unit in the 991.2, with tweaks of course.

I don't understand why 991.2 people think that the .2 is such a major change over the .1. Yes, the end result feels quite different, and good on Porsche for making a mid-cycle refresh that is actually significant. However, powertrain aside (still a flat 6 mind you), the .1 and .2 are very similar.

My point was mechanically is the .2 closer to the 992. I've yet to see anyone provide details how the 992 will be that much different. I don't mind either way, I'm just curious that's why I brought it up. Visually the .2 front bumper is completely different, the bumper is longer, the hood has the two lines that come down through the bumper, the yellow side markers are different shapes, it can be spec'd with tips in the center, the grill is vertical, the door handles completely different, inter-cooler vents, and a dial-up mode switch on the steering wheel to name a few. Was there that much difference from the 997.1 to the 997.2? I don't actually know I just ask.
I'm not sure if I'm the 'people' that think they are completely different, but I would agree with you the mid-cycle refresh was "actually significant".
I can agree the power-train aside the .1 and .2 are similar, but it sure seems to me it was a trial run for the 992 based on the limited information I have seen so far. Other than the spy pictures they are doing a pretty good job of not leaking technical details.

I think that the change from 997.1 to 997.2 was as significant as the change from 991.1 to 991.2. The engine was changed, although I’d say that change was a bit more significant in the 991 cars with the addition of turbocharging. Interestingly, I’ve seen comments from 997.2 owners about it being closer to a 991.1 than it is to a 997.1.
