So that was then and this is now 2016.. So shelved or not, they worked on not, that is the question.

Sir - we've prepared the order for your new octavia, but are you really sure you want a manual?

 

I guess it's a main box plus a splitter & a range change, like a Volvo, eg; but usually the auxiliary boxes are electrically controlled.

Does anybody know the top gear ratios, in terms of mph/1000 rpm in the latest Octavia 2.0 TDI 150, the Greenline, & maybe the Superb 2.0 TDI 150, please?

Manual or DSG?

Manual.

Love a high top gear on a turbocharged car with torquey motor.

 

Fabia 1 VRS (earlier gearbox) was 37 mph per 1000 so would do about 165 if could hit redline in top.

 

Fabia 2 VRS, in 7th, was around 27 mph per thousand so would be doing 190 at reline in theory.

 

Jaag S type I have, 33 mph per 1000 would be doing 230 a reline in top.

 

Great for relaxed cruising, Pet hate for Fabia HTP and Chevy screaming its guts out at 80 mph.

Hahaha

My Austin 1800 - 4300/70mph.

Imagine the Road&Track wear index!

How about an 850 mini on the motorway.

 

I think it was about 16 mph per 1000 revs.

 

Put a digital rev meter in there.  Was cruising just short of the redline.

 

After 2 hours on the motorway and then stopping you could still hear the ringing noises.

 

80 cc motorbike.   7 mph per 1000 revs.   80 mph about 12000 revs with expansion chamber, Again deafening.

Yep, exactly the same ratio .......amazingly smooth at 5000/80mph though that old 'B' motor......nicely balanced crank, rods and pistons.

Manual.

 

Can't say for sure on the Superb but the Passat 2.0Tdi 150 Manual is about 40mph/1000rpm

Most applications of the 6 speed wetclutch are slightly less economical than the manual. That's under test conditions though and on the road I don't notice any significant difference.

 

On many models (Like my Passat) the difference is due to the manual running taller gearing. I actually prefer the gearing on the DSG.

 

Although the 7 speed DSG is supposed to be more economical than manuals our Fabia 1.2TSi is less economical around town than our Octavia 1.2TSi Manual.

 

Just goes to show you can't believe the official figures.

 

Lee

That was my experience as well. I had two virtually identical Passat estates (even the same colour!), a manual followed by a DSG. Driven normally and with the DSG in Drive (rarely used manual mode and hated Sport) the mpg was almost the same. In fact the DSG was sometimes better as it would change up a gear when I didn't in the manual due to an upcoming island etc.

 

Had to have the Mechatronic replaced but other than that really liked the DSG and the Passats, I had three, including an earlier PD 140.

 

My love of them stopped at the latest designs though (are growing on me though to some extent) and I bought an Audi A6 Black Edition estate with Multitronic. Gorgeous car but I never really gelled with the Multitronic. Very smooth, but didn't like the mismatched road and engine speed and it never got anywhere near the mpg of the manual even though the test figures were very close. 

The DSG means running another hydraulic pump to provide the 'leg muscle' substitute........a small fuel penalty but probably offset by gear change efficiency........unless your crossing the Nullabor in top for hours on end when you're in manual 6th heaven.

The true driver of fuel efficiency and emissions is the U.S. - C.A.F.E. standards.

Corporate Average Fuel Efficiency

Aerodynamics (CDA)

Weight loss (alloys)

Thermal efficiency (direct injection and stratified charge, coil on plug, turbos etc)

Reduced friction (diamond bearing treatment, electric steering, water pump and oil pump etc) driving reduced emissions/consumption

All the tricks such as stop/start, 10 speed box with coasting function...........and on and on

Washington and California (CARB and Google) are the true 'designers' today.

(Remember to add 20% to the projected mpg for imperial)

Careful mentioning coasting function.

 

The Flat Earth society will be telling you that coasting does not save fuel.

 

One thing I like with the DSG, ZFs is the ability to knock in to neutral and coat down those long hills. Usually adds between 1 and 2 mpg and therefore a dozen miles or so tank range.  Though labels me as something out of the Deer Hunter...

 

The savings from coasting depends on what's at the bottom of the hill (brake wear is a cost).....and 'idle' fuel compared to zero (or equivalent at 'zero thrust') with minimal engine braking.

It certainly adds a line to the sales brochure and maybe a single gram to the certified emissions placard.

Nope

 

No.

 

The DQ200 is a 7 speed dry clutch box for transverse engines

The DQ250 is a 6 speed wet clutch box for transverse engines.

 

Both the above used by Skoda

 

There is also a high torque DQ500 a 7 speed wet clutch for transverse engines. Used in a few VW models like the Golf R and Tiguan and a couple of Audi models like the TT-RS and new RS3

This could be used by Skoda.

 

Most Audi's are longitudinal engined and have an inline gearbox. This is the DL501 and is a 7 speed wet clutch. These wont fit any current Skoda.

 

There is also another dry clutch the DQ380 which is just for the Chinese market.

Just reading through and noticed it has been quoted that the Golf R plus some others has DQ500 7speed wet?

Is that correct as my MK7 Golf R only appears to have a 6 speed DSG?

It is an art/science to take it out of drive and then click in back in to drive at the optimum point to get the most coasting but not waste energy with braking at any point.  Very satisfying to see the average mpg and range take a leap upwards.

 

If you already have the Dual Clutch gearbox then easy for the software to pop both clutches when one is on no throttle and in ECO mode in the mode selection.   It has spooked a few DSG owners who did not know they had it and the revs suddenly drop to tick over and they think it is broke.  

My 7 speed DSG in the Fabia 2 VRS would sometime just do it anyways, most disconcerting, and need a reset, truly scary.  Still not driven a 8 speed ZF on BMWs etc, only my 6 speed ZF on the Jaag, it sounds great.

Sorry yes, the Golf R has the DQ250 standard but there are tuners that offer a DQ500 upgrade.

Be very carefull, newer DSG's and the later ZF8HP have in built coasting functions but for earlier wet clutch DSG's and for most conventional automatics knocking the vehicle into neutral removes drive form the oil system which drops hydraulic pressure and can inhibit lubrication to some parts of the gearbox. 

There are warnings in the handbook on some models not to place the gearbox in neutral while moving and also limits on some models on how fast they can be towed and for how long.

I used to coast down one particular motorway hill which was perfect for it - the right grade, no need to slow for anything if no traffic in front etc......there just weren't enough opportunities......... but my priority is to avoid using the brakes unnecessarily.

It's just another example of safety coming second to emissions........in my day coasting would have been interpreted as a loss of control and a fail......you simply wouldn't dare.

Would not do it in a manual probably but so easy in a Auto/DSG/ZF and just nudge the PRiNDLe stick a centimeter to reselect Drive.  Would not do it very busy traffic or Kangaroos, Sheep or Wilderbeast loitering by the side of the road but when quite, works well.

And easy to damage your gearbox.

Done it thousands of times on Dry, wet DSG and ZF boxes and no problems yet touch wood.

 

Where are I do occasionally miss a manual shift a that is not a good place to be ie going in to first at maximum revs in second, ouch.

Can't say for sure on the Superb but the Passat 2.0Tdi 150 Manual is about 40mph/1000rpm

Thanks Lee. I like a high top gear if there's sufficient torque: I feel it reduces engine wear & may put the engine into its most fuel efficient rev band when cruising on, eg, a motorway.

My old Passat does about 31.5 mph/1000 in 6th (manual), & the torque is such that I feel it could pull a bit higher a gear than that.

I asked the question because I'm thinking of buying one of those cars.
