One of the European magazines quoted Walter Rohl saying that engine sizes will be 2.7t and 3.0t making 349 and 430 hp respectively. I was hoping for 3.2L engine in the S. Not a big surprise with engine sizes, but the real question is how much heavier. May bet is that they pick up 75-100lbs due to two turbos, intercoolers, extra cooling (more torque=more heat), and extra beef in the drivetrain and engine components. Oh, almost forgot, and he didn't care how they sounded but says Porsche is still working on it.
I'm personally not a big fan of turbo engines and turbo lag(yes even 0.8sec can feel like eternity to me) but kind of looking forward to new experience with the new motor. What are your thoughts?

When the 996 first arrived I vividly remember reading a head to head comparison with the 993. In virtually every way it was a "better" car. If I had had the means at that time I would have bought one of the last 993s because "there is no substiture". I's way too late now to buy a new 993. In some ways I see the GTS as the last of an era too... and I'm fortunate enough to have one on order

Ditto,....mine locked Monday.

Doesn't surprise me one bit about the size or HP numbers, thought this all along. Porsche never tramples too much on the previous model.

Lag is lag,....every turbo has it. Even Porsche turbos have it. Everytime I hear the words "virtually no turbo lag" I just roll my eyes. It may be small, but it's still there. The more cubic inches the better to compensate, but these will be smaller turbo engines. Who knows, maybe Porsche will have some magic up it's sleeves.

What remains to be seen is the torque numbers,....those will be more interesting. The sound will be very hard to reproduce vs. NA.

Turbo lag and surge has never bothered me particularly although I know some people strongly dislike it. I drove a chipped Audi TTS for a couple of years which had about the worst turbo characteristics combined with 4 cylinder sounds and actually rather enjoyed it! The hybrid electric drives coming in the 992 generation will solve these problems providing torque fill when needed as well as improving weight distribution - there's a good reason to look forward to 2019 (but no rush, please ).

Weight distribution is perfect already. 50/50 is worse than 40/60 that 911 has. Hybrid also means extra 300lbs at the minimum.

We will see. I always have an opinion (usually not good) when Porsche changes something big. But in the end, they know what they are doing. Not a big fan of the turbo idea, but I bet they nailed it. I am sure the Gen 1 991's will sell very quickly now. The last of an era.

I'm skeptical of the 349 HP number. Porsche almost never downgrades HP output form one gen to another even though it's only one HP!

Dude174

Could be 349 and 430 ps? I'm not sure what the ps means for hp, but euro magazines/drivers/specs/reviews usually quote this ps number which is less than how it's measured in the states?

The redline on the turbo engine is almost certainly going to be lower than the NA 3.4, and the 3.4 makes peak power at like 7400 RPM. Since HP is simply a factor of RPM and torque, when you compare the torque curves of the two engines, the turbo will have more power across a wider range even if the peak is slightly lower. Overall, it should be a net gain, and probably a huge gain at low RPM levels.

If you think about it, the 911 (ignoring TT/GT2) has never been a player in the horsepower war because it doesn't need to be to achieve great performance. I'd bet Porsche knows its target customer for the 911 is well aware of this fact.

In any case, I do see your point, if only from a marketing standpoint.

If these numbers are true, the Carrera S is going to be a beast.

My Porsche source has told me 380 hp from the 2.7L TT in the 991.2.

We'll see if he's right soon enough.

doc76

You make a valid point from an engineering standpoint. However the marketing department will insist on showing a HP increase from one gen to the next. I'm guessing 370 for base and 420 for S.

Benedict14

The 349HP (imperial) attributed to Walter Rohl converts to 353.84HP (metric) for the C2 2.7T motor. It wouldn't surprise me in the least if this turns out to be the case. Obviously, there will be gains in Tq with the addition of turbo charging.

"Damn Germans - I'll never for give them for Pearl Harbour". Now they're messing with my engine and the metric system

I have decided the 'smaller displacement/turbocharge thing' is kind of ridiculous and somewhat of a marketing tool as well. I have a 2015 M4. BMW of course replaced the high revving normally aspirated V8 with a tt 6. I can tell you, especially after the break in, it is really fast. Despite the glowing reviews of these new turbos there is always a turbo lag, and the mileage especially when you are on the turbo still sucks, so what have you really gained?

You've gained approval from the emissions czars' silly rules.

My order is in for a 2015.

Good call! I'd order a GTS tomorrow if I didn't have a 991S already.
