Gosh if those details are correct then a PDK car will feel very different to a manual on the road.
Came from the official press release:

Table updated, made an error*

So essentially 10% shorter ratios which will definitely make a big difference.

GT3 manual has longer gears than the PDK like I thought and is quite substantial to the speed in each gear. Guy in manual vid is not redlining either.

Only 5th and 6th are very slightly different.

The first four gears are identical (although 4th is 1.344 in the man and 1.34 in the PDK) and the 5th and 6th gears very similar (1.081 and 0.881 man v 1.11 and 0.96 PDK respectively)

As will the parasitic losses of the PDK box and extra 30 kg weight of PDK box on DIN.

0.5s faster to 100mph than the man, according to Porsche:

So the top of 2nd gear on the PDK, like the manual, gets me a ticket on every road and highway I drive on. So how does PDK solve the problem echoed just about by every reviewer with their incessant complaints of the tall gearing.

Easier to downshift to first ;-)

The GT3 PDK has lower gearing compared to the GT3 Manual even in gears 1-4 due to having a 4.5% difference in the final drive ratio.

Ah OK, not quite as dramatic as the first set of figures, sadly!
However a very worthwhile improvement nevertheless, evidenced from the acceleration times which are better over the entire speed range and considerably better lower down. A PDK GT4/Spyder is getting proper quick. In the hands of a normal driver who doesn’t smash his or her way through a manual box flat shifting as quickly as possible, a PDK car will be considerably quicker.
The car is going to feel subjectively more lively and responsive with the lower gearing even if objectively there isn’t that much difference in outright performance. However this is why we buy sports cars for how they feel and the current car to me feels a bit neutered.
Bring it on, can’t wait smile

Yes, the sheer driver appeal of an auto box is what all car enthusiasts have called for smile

Not all obviously but some of us do. Just as well we aren’t all the same wink

Pretty sure I'm changing my spec before it's locked in to a manual. Sure the PDK will be great, but rolling there will be nothing in it. May well be my last chance to have a manual NA car again. The 2k saved can go to Akrapovic.

? The PDK is slower 100-200 where it matters and that’s with its fast shift which saves at least 2/10th a shift.

Did auto sport just test the PDK and it lapped slower ?

PDK should get a 25bhp lift to match the bhp to the wheels on the manual.

Plus the £2k saving on the manual GT4 v PDK clinches it imo.

Bear in mind the PDK GT3 was priced the same as the manual. And this was a better gearbox too being PDK S v boggo PDK for the GT4.
