7hm Turbocharged November 19, 2015 Share November 19, 2015 (edited) Just wonder Porsche's PDK,Audi's S-Tronic & VW's DSG,are they almost the same gearbox,but with Different names & tuning.?All are Dual Clutch Gearbox. All three are dual-clutch gearboxes, but DCTs are a type of transmission and the designs vary - saying they are all the same would be over-generalizing, as if saying Nissan's XTronic CVT & Subaru's Lineartronic are the same. For starters, Porsche's PDK is, at least from what I can find, a design that they worked on with and manufactured by ZF, going up to 8-speeds. There is definitely some transmission sharing going on around though, as the PDK used in for the Macan is apparently derived from Audi's "DL501". Volkswagen's DSG branded transmissions are mostly from BorgWarner, with the most infamous being a seven-speed dry clutch design, known for repeatedly failing due to mechatronic unit corrosion. There are also six-speed wet-clutch units marketed as DSG. Audi's S-Tronic branding is used on a number of dual-clutch transmission units as well, for example the newer cars built on VW group's MQB, specifically the Audi A3 for example, use the same 7-speed dry dual-clutch transmission as the aforementioned 7-speed DSG. However since Audi manufactures a wider range of cars with longitudinally mounted engines, the transmissions must be designed to match the longitudinal configuration and as such not all the Audi transmissions are identical to those used by Volkswagen as DSG. Basically the tricky bit is to try to figure out which transmissions are unique to each of the group's brands and which are shared... probably easiest way is to see which platform the model is using Edited November 19, 2015 by 7hm 14 Link to post Share on other sites More sharing options...

Mercury1 Turbocharged November 20, 2015 Share November 20, 2015 Noice I didn't know PDK was made by ZF, I would say they are probably the best GB makers in the industry if not one of the best.

7hm Turbocharged November 20, 2015 Share November 20, 2015 Just wonder,Porsche PDK & Audi S-Tronic,any known problems,on daily driving.? I think they are similar feeling to DSG... but have heard some complaints related to S-Tronic... and general worry about MU failure like with DSG. Seems their multitronic is also not seen as very reliable Noice I didn't know PDK was made by ZF, I would say they are probably the best GB makers in the industry if not one of the best. I think the 8-speed ZF-manufactured PDKs are probably used in the sportscar models. I didn't look too far into it... not interested in buying a 911 anytime soon Link to post Share on other sites More sharing options...

Mercury1 Turbocharged November 20, 2015 Share November 20, 2015 My car uses the regular automatic 8 speed ZF gearbox and I have to say the gear changes are super smooth and quick and so far reviews indicate its quite reliable, I think for that I think quite highly on them haha I want a 911 but I can only afford one on my desk lol.

Thought BMWs' ZF 8-speed is a conventional automatic? I was aware some of the BMWs are using DCT, but up to now I was always under the impression the 8-speed gearbox that's been praised lately wasn't using dual-clutches...

Mercury1 Turbocharged November 20, 2015 Share November 20, 2015 Haha no you're right, only the BMW M cars are using Dual Clutch, (except M135 & M235) I'm referring to the conventional ZF 8 speed, but what I meant was as a company seeing how good they made the conventional GB I reckon their dual clutch would be superb.
