Dealer confirmed porsche did give official 2021 PDK option on the GT4 and a alleged reduction in quantity. Not sure if I really buy that as everyone seems to want to see the PDK gearing. Also did not know if it would be a no cost option or a increase of 3K on the price. RS likely will follow but still no PTS options which to me means most of the GT4 will be a large production run and not limited.

Good news only if it's PDK-S.
Fingers crossed!

PDK-S plus a modest increase in power is going to equal a big increase acceleration.

I doubt that Porsche will offer the PDK as a no-cost option on the regular GT4, why when they can charge for it over the manual.

And as for GT4 production numbers, not 'limited' but not 'unlimited' either.

How insane would it be if Porsche offered a manual for the GT4 RS!?

Stay tuned.

configurator updated with PDK option for 2021 718 GTS 4.0 and Spyder/GT4.

If you look at the technical data after changing to PDK, it the torque increases to 317 from 309. Makes the extra charge for PDK easier to swallow.

Really hope the GT4RS gets a larger torque increase than 317 with its PDK option

So most probably the same PDK from 718 base and S models. I have a 911 Carrera S currently and the non-S PDK is pretty damn quick. Anyone know if the PDK in 911 Carreras and 718 is the same deal?

RS911

As others have mentioned, it looks like the cars have the “regular” PDK. Here is the hope that the RS gets the PDK-S.

The 317ft-lbs number is interesting. We know that the original 981 GT4 was torque-limited from 325 ft-lbs (the amount made by same engine in Carrera S 3.8L) to 309 ft-lbs (Manual gearbox limitation). Clearly the 317 number is still quite limited (by software), as the displacement has grown to 4.0L but doesn't even make as much torque as the 3.8L Carrera S.

The unencumbered torque peak should be close to 340 ft-lbs. Maybe we'll see that with the RS...

I wonder if the 317 ft-lbs number was selected by Marketing Dept to offset the extra output lost as heat in the wet clutches of the PDK compared to Manual, so that the wheel torque numbers will be the same between both versions on the dyno??

Drifting

Agree since a PDK has more loss of power through the drivetrain than a manual. For example a manual 991.2 GT3 is approx 2.5% more powerful than a PDK 991.2 GT3 based on Dundon dyno data, so 8 more ft pounds in the PDK GT4/Boxster/Spyder PDK cars basically means the PDK and manual cars would have almost exactly the same power to the wheels.

No way will the torque peak reach 340 in the GT4RS when the 991.2 GT3 has 339 ft lbs. Porsche will maintain the model hierarchy. The artificially limited the 991.2 GT3 to have 7 less ft lbs of torque than the 991.2 RS, which has the same engine.
I could see a PDK GT4RS getting 325-330 ft lbs and 450-460hp.

GrantG

The 3.8L Carrera S and 991.1 GT3 both made same 325 ft-lbs...(if 339 is more palatable than 340, then fine - basically same thing)

By the time the GT4 RS is released, we'll already have the 992 GT3 specs which should have over 340 ft-lbs

If Porsche cared about hierarchy with respect to torque, why does a current Carrera S have more torque than GT3?

Drifting

Good example. And the 991.1 GT3 is also known for being the only Porsche GT car not to be endowed with a motorsport engine.

We'll see on the 4RS. I highly doubt the GT4RS gets more torque than the 991.2 GT3.

We could wager a dinner on it?? I pay if the GT4RS torque exceeds the 991.2 GT3? You pay if not?

GrantG

I think it'll have 339 or more (I originally said "close to 340"). I'll bet you lunch at High Plains

BTW, a current Carrera S makes 51 ft-lbs more torque than a current GT3 (where's the hierarchy?)

Drifting

Deal. If the first GT4RS makes 339 or more torque, I owe you lunch at HP, otherwise you owe me lunch.

Re the second part, with the turbocharged engines, Porsche is very careful about the relative HP number hierarchy between their various sports car lines, less so about the torque.
