AMS-Test M3 6MT vs DKG

[Hammer]

just released here. i ll try to get the article in digital format for you.
(results are as estimated: dct>6mt in acceleration&economy, but a bit more weight)

[Hammer]

My cam suxx...

i tryed it with handy and my old digitalcam, but the results suck, i ll share em but they are not satisfying, sorry at all, i ll translate and post it tomorrow(very tired now, we have 23:24 here in germany and it was a long day).

[!Xoible]

thanks! u probably shouldnt have posted the pics hahaha

and yes, the results are known. cool.

[JEllis]

Oh come on, what were the 0-60 times, 1/4 mi times, 30-90 etc......

Thanks for posting the info, this is what we have been waiting for

BMW M3 Coupe M-DKG

0-100km/h: 4.6s(manual 4.8s)
0-200km/h:16.0s(manual16.3s)

Don't know the other acceleration figures.

[Davinhci]

can't read a damn thing, i need to get some glasses

[trah23]

4.6, hmmm, theres this other post where the guys saying that the M-DCT is capable of 0-60 times of like 4.17 seconds or something, is he full of $hit or am i missin something......

[footie]

South is the man who should know but I don't know of any review posting a time of 4.17s.

[!Xoible]

how can they get 4.8 out of a fucking 335 manual with no LSD and get the same from a M3? give me a fucking break

Different surface grip, US mags test at very grippy tracks, plus these times by AMS are to 100km/h (62.5mph).

Also a LSD shouldn't make any real difference when accelerating in a straight line. The important thing to look at is the 100km/h ~ 200km/h split times between M3 and 335i, I think you will see that all of the M3's problems come from traction.

different track different day different driver.... just because C&D get a 4.1 0-60 doesnt mean you will or that the next day they will be able to duplicate it. This is not a tough concept....

Footie, as always time for a math "tune up". Rounded to one decimal place 100 km/h = 62.1 mph. As I like to say the devil is in the details.

What makes you think an LSD doesn't dramatically help for accelerating in a straight line?

You are missing so much that I don't even know where to start.

Actually I'm not really that rude. The reality is that 0-60 times vary magazine per magazine. The best 6MT time so far is about 4.1. But these are with drag rollouts and powershifts. M-DCT times have not been determined by the major US mags yet, so we can't really compare.

And more importantly, this is a german mag so its 0-100 (0-62), not 0-60. That's worth a tenth or so.

Hey guys,
i m back from work. as promissed now i ll translate the article for you ( and dont blame me for posting the pics, nexttime i ll just be quiet...):

Headline: Gearing and Smoke , the bmw m3 gets more sporty: with a sequential transmission, 7 gears and doubleclutch.

under the pictures(from left to right):
first: advantage for the dct: acceleration with the m3
2nd: the small button behind the shifter controls the shifttimes
3rd: yellow, red, shift: lightsignals for the rpm/s
4th: shifting is avaible by paddle or the shiftknob

text: super sporty cars shift sequential - not just in the formular 1. the automated transmissions were sucessfull, that made some people wondering about the m3 being sold only with the 6mt at first.
now a dct is avaible again, with 2 clutches, and this is the technique which will be the future. there is no more traction interruption and shifting is just noticable on the rpm-screen. the comfort highly improved, compared to the older smgs. the m3 is as smooth as a normal automatic transmission now. the real fun begins when the driver takes the transmission in the way it is: a "manual transmission" without a 3rd pedal. In the lower shiftmodes the shift isnt noticeable at all but with increasing mode it gets noticeable, but less than at the smg.
otherwise it shifts faster than a professional mt-driver. The proof is given by the auto-motor und sport-measure: the dct accelerates better than the mt. already from 0 - 100 km/h its 0,2 sec faster. this is not just caused by the shorter shifttime but also by the lack of traction interruption. the translation in the 7th gear is just a bit longer than in the manual transmission. therefor we have shorter changes of the rpm by shifting and the engine has a higher rpm and according to this power after shifting. at least it has a better fuel ecconomy.

AMS-result:
pro: v8 engine with impressive power, excelent dct-shifts, comfortable automatic, excelent driving abilities, breaks and ESP.

con: bad suspension-comfort, bad fuel ecconomy

6mt vs dct
v8
3999cm³
309kw(420ps) at 8300rpm
400nm at 3900rpm
1655kg max 425kg extra
acceleration:
0-100 4,8 / 4,6
0-200 16,3 / 16,0
ecconomy( l/100km): 15,1 / 14,7 at 98octan
price: 66.650,- / 70.450,- €

thats it.

[ihyln]

makes me glad I'm waiting for a DCT. Even though the wait is agonizing.

[adamr]

0-200 16,3 / 16,0???

did another thread not say 16.3 for the manual and 15.2 for DCT, i remember the 1.1s difference to 200km/h

i know that but my complaint is most magazines have consistently gotten 4.8 from 335's.

Slips only really come into play in a corner when the un-loaded wheel has no resistance and spins, that's when a LSD feeds more power to the wheel with grip. On a straight line acceleration both wheels are getting an even grip load.

[footie]

This result is a very poor reflection of what dual clutch is capable of. Either this M3 was a bit under par in terms of performance or M-DCT has some consistency issues (something I very much doubt).

4.6s is poor for even a manual which doesn't has such things as launch control and zero power lose during shifts, for this time to be the DCT car is very unexpected and a little disappointing.

[phoenixbmwlife]

Maybe the DCT wasn't broken in yet so they didn't use launch control. 4.6 to me as well is disappointing but its only 1 review. Pretty soon we will have more data to add to the mix.
