AWESOME!

SO Glad I got the DSG!!!

 

[davidp]

thats fascinating stuff. Does is not mean though that when one clutch is engaged the second clutch is held open. So when you drive one clutch is always held open all of the time. In a normal car that would wear the clutch out so how do they get round that.

 

[schoolhousefred]

Very good question David. I suspect the answer has something to do with the fact that wear only occurs on clutch which is subject to engine rotation. On the other side, where clutch is open, it is not subject to engine rotation and thus friction wear. Let's see what our "Technical Adviser" has to suggest .... calling Simon!

Hi,

No wear is caused when the clutch is open as it is a wet clutch and has no friction to speak of when open... The only realy friction occurs during engagement and disengagement.... When fully open or fully closed, no friction occurs.....

Hope that makes sense!

 

[schoolhousefred]

Very good ... thank you. And in fact, then maybe clutch should last longer since there are two clutches, and in total one only makes the same total number of gear changes regardless of the number of clutches? (assuming the same number of gears and same gear ratios)

 

[SiJ2000]

As they are wet clutches, they should last longer and better than standard dry clutches used by manual boxes....

Plus the engagement is so much quicker that the "vulnerable" time for the clutch is greatly minimised.

Oh cool answer. You are the man!

PS: Just been watching old scrubs repeats on E4

PPS: my next car will have DSG

PPPS: you are right Fred, two clutches are better than one!

DSG ROCKS!!!!!!

Also, it is noteworthy that the hydraulics will adjust if the clutch wears slightly.. The issue with people is that they don't adapt so well to a rising biting point in a pedal clutch, so the wear can be increased as the clutch wears down!

 

[schoolhousefred]

two clutches are better than one!

So maybe it is a corollary of "two heads are better than one"?
Cheers David!

I suppose you have to keep in mind as well, the fact that the extra cost of the DSG as opposed to the manual would easily pay for a new clutch should the need arise. Still I do like the DSG and wish I had got the option.

Again, you are probably correct, BUT I think most people buy because of it's ease of use and performance. The fact that is probably longer wearing is just a bonus!

One thing I'm finding in the less than 24 hours since I got mine, is that there is little point in driving it like a manual. WHen you are decelerating and pull it back through the gears, there is very little engine retardation as the DSG blips the throttle and keeps the engine revs up. It also changes down by itself when in 'D' and you start to brake.

One thing I didnt realize until I read the manual is that the 'S' position isnt for 'Second', it's for 'Sport'!. Will be interesting so see the difference there.. It certainly is a nice transmission that's for sure... Well worth the money IMHO

 

[schoolhousefred]

You are gonna love it! And there is a big difference between D and S ...... much higher revs! Enjoy dcoz!

Seriously, DSG is one of the best advances in automobile technolgies in a really long time.

Just the other day I was doing some autocross against a Mazdaspeed 3 V6. Those cars only come with a manual transmission. He easily has more HP than I and could whip me off the line. But as soon as he had to shift up a gear you could see the EOS gain by leaps and bounds. The DSG made up for lack of HP and over took the Mazdaspeed within a couple seconds.

The driver of the Mazdaspeed came up to me after the challenge and told me he was confused and amazed that the EOS was so "FAST".

Ha!

Good times

 

[rajtamarind]

The DSG is the best investment i've ever made. i sometimes use the manual mode to change up and let it do all the down shifts. Most of the time i leave it in auto- its just so much cleverer at shifting gears than i am.

 

[SiJ2000]

Indeed... I couldn't be happier either!! A 325i tried to get me at the lights.... As soon as his clutch went down to change gear, he lost it!!! NO CHANCE!!

Hmmm......How is that possible - unless the 325i driver was rubbish

The E90 325i in manual has a factory 160kw, straight 6 & Should be able to beat a 7 sec sprint from 0-60 I mean. Probably closer to the late 6's I reckon.

I know the older 325i's (the e45's) were only in the 140's kw region I think, but in manual form cld be able to take an Eos...surely!
Even if you factor in the weight differences too

What gives? Surely the DSG setup isnt that punchy & in manual form, could surely only achieve a mid to late 7 sec sprint???

 

[IanJ]

What is not widely known is that to achieve the published 0-60 times in a manual they generally ignore the clutch - not something you would want to do in your own car!

DSG is designed for one clutch to be disengaged all the time so it should be designed (this is VW after all, not Lexus or Honda) to handle the disengagement.

Most normal clutch wear is because it is slipped by poor drivers.

Will be interesting to see the new 7 speed DSG - it is dry clutch rather than wet!

 

[SiJ2000]

I guess the bmw driver was a bit crap, but the road also narrowed, so he had to slip behind me.. If it was completely straight, he would probably have won, but in this real life circumstance, not one of a racing track, the EOS DSG won!
