what are you talking about?

do you actually know how the sequential works/acts?

Yeah, I just think a PDK tweaked to act like that would not work. I believe PDK already has a setting where you use the center console knob thing and either bump it up or down to shift, but that is no substitute to a manual.

In order to make it act a lot like a sequential, they'd probably end up spending so much money and adding so much weight it'd be more practical to put an actual sequential in it. If they could pull it off though, and it actually worked, I stand corrected.

And GTCole, I think I spoke to soon about that 8cyl thing. Apparently now the new GT3 and GT2 are supposed to get 8cyl boxer engines that can shut down two cylinders. I don't believe it at all, but here is the article anyway, translated from Swedish.

Too many rumors for this new GT3!!!!!



Porsche 991 GT3 and GT2 may have Eight-Cylinder Boxer Engine...

(18 February 2012)

Porsche will release the GT3 version of the new 991 within a year - and now the rumour is that boxer six engine is replaced with an eight cylinder boxer engine that may allow cylinder shutdown. According to the sources of Auto Motor & Sport should also reduce the manual transmission is replaced with PDK or a robotised gearbox...

Rumour for the next Porsche 911 GT3 and GT2 is huge. Triple Turbo GT2 or not? Manual, PDK or robotised gearbox? Eight cylinder boxer engine or boxer six? And also electric steering from 991 Carrera?

After the launch of the new 911 Carrera and Carrera S are of course more versions. The GT3 model will be launched in 2013 and Porsche are currently considering whether to get a manual or an automatic gearbox. Project Manager for the Porsche 911, August Achleitner, tells "Inside Line" that only one transmission will be offered. Only 30 percent of the 911 buyers choose manual transmission.

"When we launched the 911 Turbo S, we offered no manual transmission, but we have not received a single complaint," he tells Inside Line.

While claiming one of our reliable sources that the decision on PDK gearbox in the GT3, GT2 and GT2 RS is really not at all. Porsche has a strong focus on reducing weight, and not only increase the peak. The PDK gearbox increases the weight by over 50 pounds. The 7-speed manual box from the 991 Carrera, or a robotised gearbox is much easier -- Lamborghini chose such robot box at the development of the Aventador.

Here are thinking Porsche to install an eight-cylinder boxer engine in the new GT3 model. And it fits, according to our source. To provide four liters, six cylinders require very large piston diameter. The move to eight cylinders with smaller piston diameter means that the length need not increase as much.

There is more news for Porsche enthusiasts to react to...

A reliable source reported to Auto Motor & Sport that Porsche developed an eight-cylinder prototype engine with four cylinders in the middle that can be turned off to save fuel and, in particular reducing emissions. Cylinder shutdown process will work much like the V8 engines sitting in the Audi S6 / S7 / S8 and Mercedes AMG models.

The current, "old" GT2 engine must have a large fan that blows out fresh air in the exhaust pipe to get the right issues. Without the system, the engine would not pass environmental certification. With eight cylinders and cylinder shut-off increases the chances of getting a cleaner engine that meets the EU requirements. The decision whether there will be eight or six cylinders in the boxer engine is not time yet.

Previously, we reported also that the upcoming Porsche 911 Turbo can get triple turbo to increase power. However, this is contrary to Porsche objective to reduce the weight instead of increasing the peak power. Clearly, the Turbo model gets two turbos, as in 997-model, but soon, the aggregates are placed in front of the drive shafts - that is usually under the rear seat.

It is not yet known whether the system of turbochargers in front of the drive shaft end up on the Turbo model only, or the monster model GT2. The location would provide better weight distribution and thus a balance approaching a mid-engine, but the question is whether the typical rear-engined 911-balance would be lost?

Electromechanical steering from 991 Carrera to end up probably in GT3 model.
Project manager defends the system to the "just remove the steering feel you do not need."


o further improve the balance Porsche working on a gearbox using the gear to extend the distance between the center of the ring gear (differential) and the socket for the axle shafts. Then the motor can move further towards the center and the car gets a better weight distribution.

And it does not stop there: August Achleitner confirms that even the GT3 and GT2 versions, the new electromechanical steering of the 991 Carrera, which received some criticism because the feeling is not quite match the steering feel of its predecessor, 997 model.

"The new system only removes feedback that you do not need. All of our racers prefer electromechanical," he says.

Want a scoop? Porsche will not use a 8 cylinder.that is all.

Carrara, have you driven a car yet?

I don't mean to pick on you. You're just in an area where actual experience is needed to make a valid opinion.

From what I have heard the new pdk is very very nice. But for a GT series car, a sequential would be badass.

People are against PDK, but sequential sounds like good deal.

If you have ever ridden a motorcycle, you know that the manual transmission in a motorcycle is nothing like manual in car.
On a motorcycle, you shift gears by clicking a lever up or down with your toe. It is a much faster way to shift.
This type of transmission is called a sequential gearbox or a sequential manual transmission - gearbox in racing cars work on same principle.
If we see highly optimized sequential on 991 GT3 that is very durable and light, maybe we can talk about replacing famous GT3 manual.

I`ve tried to find some videos of cars with sequential transmission & I found this: 997 GT3 RS with Sequential (shift stick looks ugly as hell LOL)

the thought of 8cylinders makes me want to cry, i hope they dnt but it cant be totaly dismised, porsche has been known to make ruf test out its future ventures and ruf has been testing an 8 cylinder carera for a while now, the competetion has become ruthles and porsche just might need to do something about it, im afraid the 2 extra cylinders would be their solution


as for the transmision, i know pdk is going to be faster and les fun but what makes me real sad is thats its gona destroy the gt3 cult, bunch of like minded people that love to drive and participate in trackday events and allow access to any one with the funds.

i keep hearing sequential requests but thats not possible with the way conventional sequentials work, unles porsche invents and whole new one, sequentials canot be driven in trafic, they need a high reving launch, and they also need rebuilding after a certain hours of use
