Anyone have any clue as to why the data (in the new May brochure) for the CR140 DSG is 5-10% worse than the manual? For instance:

0-62: Man=9.9; DSG=10.2

Combined fuel consumption: Man=47.1; DSG=43.5;

CO2: Man=157; DSG=169;

First question I suppose is whether these differences are real or is it another set of 'typos' from SUK?

0-62 differences are I guess of academic interest only - it may be unsurprising that there's a very small difference between the two, given eg the difference in gearing, the fact that the DSG may well make an extra gear change etc. And in practice the DSG may well be quicker for most drivers, given how difficult it is for the average driver to match factory 0-60/62 times. (In passing, an interesting video on this for the new Golf R at:

http://www.autocar.co.uk/VideosWallpapers/Videos.aspx?AR=249585

But why are the consumption and CO2 figures so much poorer? As has been previously discussed for the 1.2, I thought that the DSG was supposed to help consumption/CO2?

Stop Press: Ah, I've just noticed that the CR140 has the 6-speed DSG not the 7-speed. Maybe that's part of the explanation - but only part though.

Hi prodata,

the 140 DSG as you say does indeed use the 6 speed (wet) DSG box, I believe for reasons or torque. Also the figures suggest that its not quite as efficient as the manual version.

Having looked at a CZ home market sales brochure My link, it gives an overall fuel average as 6.5/100km, compared to 6.0/100km for the manual and as per your figures 169 for the CO2 (DSG or AP in CZ)

The most efficient 4x4 version is now the 170 TDI CR due to the introduction this week of the new 2nd generation engine (110 CR 2nd generation at launch, while the 140 CR was upgraded WK45/09)

It is curious to me that the "old" and the new 170 CR is more efficient than the 140CR??? They share the manual gearbox with exactly the same ratios and final drive ratio in the old version. Did they change the final drive ratio in the new one? In the old 170 (like mine) 5th gear does not quite make the top speed, and 6th seems like it has more to go. Naturally it is difficult to measure, as even on the Bahn, the opportunities for that kind of speed are limited - by a chicken driveer too.

Rolling road tests of VAG diesels often return number of both torque and hp higher than specifications.

I have no accurate way of measu´re, but the 8.4 seconds to 100 km/hr seems on, and I suspect that it is faster to 100 by starting in 2nd gear, bypassig 1st, saving the shift, as 3rd is more than enough for the 100 km/hr.

Academic really, as the real on-road performance happens in 3rd to 5th with no shifting.

It would be interesting to know how the CR engine has been improved.

Are we talking improved mechanical components, better injection systems or are they merely down to an improvements to the electronic mapping that persumably can be applied to 'older' versions by way of software update.

Hi,

there has been changes to the electronics in that the newer engine has a different ECU. Also some physical changes between the early 140 CR (mine) to the later 140 CR, exactly what I'm not sure. JonA did mention last year something about the injectors and from photo's of later production 140's I've noticed the oil filling point has moved from the right to the left and theres other minor changes to the engine cover design; although many of the ancillaries look the same.

The other non engine related change at that time was a reduction in rear brake disc size

Having now realised that it's the 6-speed DSG we're talking about here for the CR140, makes it all the more frustrating that - currently at least - there's no CR170 DSG. The CR140 DSG shows that any issues with the Yeti diesel and 4wd have been resolved and the 6-speed DSG is presumably competent to handle the power reliably, at least as judged from older VW group models.

One might assume that as the 6 speed wet plate DSG is limited to 350 Nm and VAG diesels are know to exceed their specifications, the old 6 speed DSG is judged not up to the task of handling the 170.

No doubt other designs from Audi will migrate down eventually. The 1.2 TSI and 2.0 140 TDI engines are probably judged the mainstream of Yeti powerplants, so that is where the DSG is most needed.

But wouldn't this be the same DSG box as already used in the Octavia CR170 DSG and with the same headline engine parameters as the Yeti CR170 (ie 350 torque)?

All the talk is of 6 speed DSG but Skoda UK website says 7 speed for the Yeti diesel.

To clarify, Octavia VRS CR170 uses a 6 speed DSG 'wet' and the Yeti CR140 uses a 7 speed DSG 'dry'. Yeti 1.2 petrol uses a 7 speed DSG 'dry'.

It does however highlight that the DSG does not do much for fuel economy on the CR140 whereas things look quite good for the DSG on the 1.2 petrol.#

Can't see why the 6 speed DSG could not be used on the Yeti CR170 - unless there is something preventing use with the 4wd. That sounds like a very nice combination if it were feasible.

But not in the footnote to the engine specs in the new Yeti brochure (p22-ish), where it clearly says 6 speed DSG for the CR140. So another SUK discrepancy in their literature which leaves us not knowing for sure. But given the known power/torque limitations of the 7-speed in installations so far, I think I'm more inclined to believe that it's the 6-speed.

Yes, I've just looked. A very definite contradiction here! We'll have to get a certain future owner (the chap from Sussex) to count the gearchanges when he gets his

The DSG Yeti TDi is a 6 speed box not 7 speed.
