SMG vs. F1 vs. selespeed shift times...

And they're all obsolete:

I drove my friend M5, the shifting takes sometime to engage which is quite noticable

 

I drove her shifting at approx 8000+ revs with the ME7 package, it did'nt feel like being as direct and responsive as the F shift. Seems like it takes time to engage and maybe more responsive if between the shifts the throttle is released for a ms. Just my 02c

 

ME7 i understand is the rev limiter bypass/ speed limiter bypassed from the factory on the new E60 M5.

 

I am about to design a training course for a motor manufacturer that covers sequential transmissions, can anyone add to this list (and confirm the Veyron is DSG)?

Semi-auto manual with 1 clutch
-------------------------------
Alfa Romeo Selespeed (156, 147)
BMW SMG (330Ci, M3, M3 CSL, M5, M6)
Ferrari F1 (355, 360, 430, 550, 575, Enzo)
FIAT Selespeed (Stilo)
Lamborghini E-Gear (Gallardo)
Maserati (MC12 same as Enzo)
Mercedes Sequentronic (possibly no longer available)
Vauxhall Easytronic (Corsa, Astra Sport Hatch)

Semi-auto manual with 2 clutchs
--------------------------------
Audi DSG (TT, A3)
Bugatti DSG (Veyron)
Seat (Altea, Toledo, Leon)
Volkswagen DSG (Golf, Jetta, Passat, Touran, Eos)

Semi-auto CVT based
---------------------
Audi Multitronic (A4)
Mercedes (not available anymore, but was on C-Class for a while I think)
MG (MGF)
Vauxhall (Corsa)
Toyota (Avensis – I think??? anyone confirm???)

Toyota MR2 also has paddles but not sure if single clutch or CVT based???
Vauxhall did a CVT option too, not sure if still available???
Mercedes A-Class had an automatic clutch (manual gear lever)

Thanks for any input.

 

German cars manufacturers all have the option to supply the car with the speed limiter removed (as the German market is the only one to have a voluntary 155mph limiter as standard), but they dont publicise it and each marque has different methods. UK M3 CSL's could be supplied unlimited if the purchaser had a competition licence etc. Cant see the point in having a rev limiter removed though and doubt if you can. The 'ME7' is probably an internal ordering code, thats all. With all the litigation issues in the US I doubt BMW-USA would want owners to have factory de-restricted cars hence lack of knowledge.

 

I think he was just pointing out that the limiter had been removed, not that it altered the SMG shift timing, unless he meant that the rev limiter being removed = more revs = faster shift, but as I said I doubt if the REV limiter changed anyway.

The CSL feels like it has a faster shift than the standard M3 SMGII, certainly in "silly mode" but that may just be stiffer bushes transmitting the BANG into your backside with more force

In my experience the shift duration varies with a few variables like shift program selection (if available), throttle position (both at start of, and during shift), road speed, vehicle acceleration and revs plus an element of wear relating to clutch, gearbox, electrical actuators and hydraulics. I think the actual shift times quoted are pretty general when talking about tenths of seconds. I wouldnt fancy having a sequential shift more violent than a CSL on full song.

 

Count the MINI Cooper (not the S version!) in for a CVT transmission.

The Cooper S has an auto option but it's a regular slushbox.

The MINI Cooper has a true CVT.

When my car was in for service, i got a A3 DSG for a loaner. That car shifts SOOOO fast. I think it could take a SMG shift. It was like constant thrust, simply amazing.

 

Forgot to add that DSG shifts in 8ms Another score for Audi.

 

Note to self...don't pick up a 1 year old certified M5 at a dealer!

 

Rockingham (in the UK) had x8 CSL M3's and numerous standard M3 SMG's as school cars which they used to rotate through the dealer network every 3 months...

Thanks MT, didn't know about the Mini.

 

IMO I find that the DSG is too good in that its seemless shifts take some of the "driving dynamics" out of the gear shift process. Its like a torque convertor automatic but without the performance or consumption hits.

In general I would say that the manual gearbox based single clutch systems give the user auto features in a manual system whereas the DSG gives manual features to an auto system, if you see what I mean. I prefer the single clutch (especially in SMG form) for its violence and dynamic appeal.

Another point, what do you think of Audi re-branding DSG to distance themselves from DSG's on VW's ... they are going to call it "S-Matic" apparently (or should that be asmatic lol).
