Semi-Auto / SMG / Tiptronic / DSG gearboxes
-
Who here has driven or owns a car with a form of semi-automatic gearbox?
What other cars were there? What are your thoughts? Is it the best thing since sliced bread or has the lack of manual shifting and clutch pressing removed a sense of enjoyment and part of the involvement of driving?
My old Opel Corsa used to have Semi-Auto (aka Steptronic) gearboxes, frankly, I hated it, due to the fact of the obvious jerky nature during shifting up of gears

i have an smg gearbox and i love it!!!

i like paddle shift that came with ur SMG..very good...Originally posted by SEI:i have an smg gearbox and i love it!!! -
Wha so many code words? Wat is SMG? Or u spelt wrongly as MSG?

no lah...all this are auto cars' manual override function nameOriginally posted by TwinPire:Wha so many code words? Wat is SMG? Or u spelt wrongly as MSG?
DSG is direct shift gearbox...tink smg means semi-manual-gearbox -
SMG- Sequential Manual Gearbox
DSG- Dual Sequential Gearbox -
DSG is Direct Shift Gearbox as wikipedia stat...Originally posted by TwinTurbo_Supra:SMG- Sequential Manual Gearbox
DSG- Dual Sequential Gearbox
DSG means changing gears will not have any loss of power as there's like an inner and outer clutches...its similiar to CVT.... -
Thanks for the headsup

IMHO i find the DSG a technical marvel...way better than the SMG or any other flappy pedal gearbox...worst ones are in the aston....

u really watch too much top gear.Originally posted by AE86tofu:IMHO i find the DSG a technical marvel...way better than the SMG or any other flappy pedal gearbox...worst ones are in the aston.... -
DSG... its a wonderful technical marvel. most "semi-auto"s in the market are just automatics with an ability to change gears sequentially, and they're often not up to the job. so much so that some cars i really prefer to leave them in auto mode.

As far as I know, these are few examples of different type of fast cars using "semi-auto" gearboxes:-
Ferrari 'F1' transmission : proper manual with electronic clutch and gear shift - on most models these days, standard on Enzo. Launch control and shift speed settings.
BMW SMG : proper manual with electronic clutch and gear shift. M3, M5 and M6 only. Also has tricky launch control.
Maserati : Ostensibly same gearbox as Ferrari
Lamborghini : eGear - I think its an electronically controlled manual (As far as I can tell, happy to be corrected)
Aston Martin : electronically controlled auto (As far as I can tell, happy to be corrected)
Porsche : Tiptronic is electronically controlled auto
Audi/VW/Bentley : DSG twin clutch preselecting gearbox.
From what I've read in magazines and articles, the Ferrari box is the best, some people rate the BMW SMG and others hate it. Personally I think it is the future of fast cars but the technology is still maturing and people are still getting used to it. The DSG box is meant to be brilliant as well, particularly in the Bentley where it has to handle more power and torque than an F1 box yet still come with a 3 year warranty
Guess Opel has a long way to go in correcting & further tuning those sequential gear shifts -
those are facts...and u cannot change them....and the DSG shifts faster than a manual....Originally posted by TwinTurbo_Supra:u really watch too much top gear. -
Spot on.....that's what the principal objective of DSG technology is all aboutOriginally posted by AE86tofu:those are facts...and u cannot change them....and the DSG shifts faster than a manual.... -
oh yea if i am correct the 1st car to pioneer that techology was the porsche....

bentleys are outrageous....*thinks of the anarge T*Originally posted by blurberry:The DSG box is meant to be brilliant as well, particularly in the Bentley where it has to handle more power and torque than an F1 box yet still come with a 3 year warranty -
porsche were the pioneers of tiptronic i think.Originally posted by AE86tofu:oh yea if i am correct the 1st car to pioneer that techology was the porsche.... -
I still prefer the Voith gearboxes.
That one uses buttons. Its operation is very straightforward. -
Wow so technical this thread, dun wan to read liao
