Lap times DCT vs Manual

[footie]

Hi guys,

Don't know about you but things are very quite on the DCT with regards to actual figures from magazines. Lots have tested it but as of yet very little info is appearing.

Like what's it's time on the ring? And why only one magazine has only figured to car for acceleration? The car has been on sale in the US for over a month and not US magazine has any times on the car.............why?

Questions, questions.

The only DCT tested in a magazine that I've seen was a convertible. Which is not the car you'd want to test for benchmarks of performance.

I suspect that for whatever reason, BMW has not made the DCT available for press testing.

Only DCT vs 6MT I've seen so far is autobild. 3 tenths in DCT's favour on the Conti test track

BMW M3 manual vs M-DKG

--------------------------------------------------------------------------------

Manual

0-100kph: 4.8s
0-200kph: 16.3s
80-120(6th): 7.6s
fuel cons.: 13.8l
lap time: 1:35.41

M-DKG

0-100kph: 4.6s
0-200kph 15.2s
80-120(6th): 6.3s
fuel cons.: 13.0l
lap time: 1:35.11

they conclude that the 6mt feels archaic in comparo with dct and that the difference in laptime is actually quite big. They also say that the DCT is more fun to drive

If you have either a manual or a DCT car then please post your
comments in either of the two 'Ultimate guide to.....' threads.

please refer to the Ult guides.

The one figure which is of interest to me is the ring time. I know swamp (myself included) feels that on the ring it's time should eclipse that of the manual by as much as 5secs but still no test by SportAuto which is a real shame.

Also why no US test results, they have had the car on sell for over a month yet no proper tests, is it like skierman64 said, BMW are deliberately stopping magazines from testing the cars apart from the usual FIRST DRIVE impressions that are all we are seeing of late. Very strange.

Well, if you think about it, besides us BMWphiles the mags probably figure that there is probably not a demand for this kind of real review. In fact, if anything, the most I would expect from a mag like Automobile or R&T is a one page review of the new tranny and most mags have already done that with the Cabrio..... all in all, the DCT is the faster M, I think the SMG equipped CSL shows which type of tranny BMW is putting their money behind...

5 seconds? no way. I think it will likely be more driver dependant. SMG was no faster around laps.

The 5 seconds I am talking about in on the ring and nowhere else. Think about it, the DCT vs manual should make a couple of tenths on the shorter straights on the ring and a good half a second on the longer ones, if everything else stays the same that would amount to about 5 seconds. The only reason for this not to be the case is that the gearbox does not allow the driver total control.

You also have to remember that the old CSL had a different software to the standard M3, the same will be true of the new one and if there is doubts over the total driver control with the current DCT then the CSL will address these concerns and make it the perfect track tool.

SMG had neither the gearing advantages nor the shift time advantages of M-DCT. SMG vs. M-DCT = case closed, PERIOD.

I disagree with your sentiment that ALL M-DCT (or MT discussion should be in the Ultimate guide threads). Or maybe you were just poking fun at the creator of those threads?

I believe his comments were directed at gorun and not me. But then again....
