911 [Spy Shots] 2013 Porsche 911 GT3 first spy pictures

[donkeykong]

Most probably Geneva next year, though I have read possibly as soon as Paris this year, but I doubt it. It is probably Carrera 4, 4s and possibly Targa that will be revealed at Paris this year.

What about the Turbo can we expect that to be unveiled at Paris?

Besides what I read on forums I have no idea and what I read is Geneva next year for Turbo too. But may be Tokyo, if the GT3 is really at Geneva or maybe GT3 is only in Frankfurt next year.

As for sequential vs PDK for GT3, I highly doubt it is sequential. There are number of interviews from Porsche higher ups that state they are actively looking at sportier versions of PDK (PDk-S?) for the GT3. As for sounding like a sequential, it is probably just a matter of programming the software to have a brief pause. Anyway I don't how it matters, as long as it is not a manual - all the paddle shift transmissions are pretty much the same when to comes to the driving experience.

Meanwhile here is a video of the supposedly 991 GT3 cup or RSR...

What makes a good driving experience? The MP4-12C lost all against the 458 Italia so as the GT-R agaisnt the 911 GT3. Sound does play a role, so as how the gearbox feels, DCT has automatic feel by the sound. Of course changing gear is made the same way, through paddle shifts.

^Come on Levi, don't make tangential arguments for the sake of making one. What I meant is compared to the difference between a manual and any of the many flappy paddle transmission technologies, the difference between the flappy paddle transmissions themselves is very little as far as the driving experience/technique is concerned.

Sure. Just if a dualclutch gearbox sounds more like a sequential gearbox then as an automatic gearbox, it is better, but of course doesn't change the driving experience compared to a manual. Do we know if the 911 GT3 comes with manual also ?

Now it makes sense. That is a GT3 Cup 991 car testing and it makes sense why it is a sequential single-clutch simply because that is the defacto standard in racing.

Regarding the road going GT3, I can bet the tuning will be finalized once they have raced with the GT3 Cup atleast a few times. It could have a PDK or maybe again manual transmission only. It is anyone's guess.

 

[hoffmeister_fan]

Is it weird that I am more fascinated/interested in this versus the upcoming 918? And believe me, I am in awe of the 918 and its potential.

There's something so purely Porsche about the GT3, you can't help but revere it.

 

[Mr Robert]

I have the same feeling. 918-what? A new GT3, however, turns me into a 5 year-old at christmas...

PDK would technically work but enthusiasts don't have too many warm words to say about Porsche's PDK, let alone GT3 customers. So either Porsche would have to rework PDK or adopt MSG(Manual Sequential Gearbox) from their racing program.

Since it is the same car going around the same track, difficult to tell if the pics are new or old ones being regurgitated, but anyway at least they are high quality ones -

So a little birdie has just tweeted me that sequential transmission will not be in the new GT3 . Not user friendly enough, too rough, outdated. My guess is the PDK.

Read it on the 918 thread, thanks for asking.

Curious if PDK will be the only transmission that'll be offered, or if it will be an option to a manual transmission.

Interesting. PDK isn't entirely out of the question. It could be workable with racing biased modifications. If the 918 features PDK its unlikely to be the less-than-impressive stock version currently used across the Porsche lineup.

I wont be surprised if the GT3 is offered with both a manual and a sequential transmission, and the irony of it all, is that the sales of the sequential transmission will probably be more than the manual.

................and then the subsequent generation only comes with PDK. That has been the path for Ferrariäs mid+engine car and the BMW M5. People whine online but sales speak the opposite.

Funny, because that is what ALL race cars use.

Race cars have to abide by rules, and lot of them forbids automated shifting/clutch operation/seamless shifts etc.

People also need to stop making 'but race cars use it' argument blindly. Race cars also use straight cut gears, would you like that too instead of helical gears in your street car? Just cause something works in a race car doesn't automatically make it a better solution for the street, even for a hardcore car like GT3.

What's the difference?

 

[Levi68]

What's the difference?

Straight Cut

Helical

Helical gears are used on street cars for there smoothness, straight cut gears on the other hand are stronger, thus used on race cars where the stress is high.

 

[Sunny]

More than smoothness or rather lack of it, it is the sound of a transmission with straight cut gears that would would make you go mad - it literally sounds like a dentist's drill going off inside your head.

Also strictly speaking straight cut gears are not stronger than helical gears, but they are more efficient. Cause of the angle of teethes in a helical gear, some of the energy is wasted as trust load on the shafts. This also means you need stronger (heavier) transmission case to compensate for it. You can use a double helical gears to cancel the trust loads, but they are still inefficient compared to straight cut gears.

Apparently that is also where Citroen get's it double chevron emblem from. Or at least that is what I have read on the interwebs, so take it with a handful of salt.
