DSG Fuel Consumption Compared to Manual.

[Itsagthing]

Dsg popping and flames ohhhhhhhhyeah, I get 20 around town and about 27-30 on motorway but I only do about 2000 mile a year so only gets too stretch its legs around the tracks

[Tatebailey1992]

Seeing I owned a Manual MK5 GTI for around 3 years and did the better part of 65,000km's in it.
Had a MK5 TDI DSG, for 6 months and did around 25,000kms in it.

I now own a MK5 GTI DSG myself (Well the girlfriend also has a DSG GTI) only for around 6 weeks and already done 6,500km's in it as well.
My DSG GTI is far more economical than my manual GTI ever was. Even with the DSG being Stage 2+ as well.

I have done the same 1500km's round trip in my GTI as I did in my TDI, both's fuel consumption were/are identical, 650km's per tank.
Over here in NZ you have to pay road user charges on top of the diesel pump price (per 15,000kms). Then if that's not bad enough, if you drive a diesel or hybrid car.
Your yearly registration cost are almost double compared to standard car. So over here it made no sense to keep my diesel and simply just get another GTI.

Either way, go drive both. A DSG equipped car you really need to drive for a few hours at least (if you have not ever owned/driven one). then compare the DSG vs manual debate to yourself. Then select which ever one you prefer. Regardless of what any of us say. I have owned both, given the choice, I would always pick the DSG over the Manual.
But hey, thats just me. Everyone has there own right to their opinion.

Remaps will give u a better fuel consumption

Bit of a sweeping statement. Non of my cars have had improved mpg from remaps.

Why is it a sweeping statement?
Owned both, OP is asking if switching from TDI to GTI would they notice much difference?

Strangely enough, all my GTI's are more economical since the REMAPS. I know TDI's are always perform better with mileage a power after REMAPS.
Use to own a 2002 A4 TDI FWD (AWX engine, 130hp PD). After a remap i gained almost 35kw's at the front wheels from a remap alone.
But managed on average around town about 100-120km's per tank more. On the open road thou, Went from 950km's to 1250km's to tank of gas.

But now I digress from the OP questions.

More power more fuel.

I know if I granny drive it then its the same as standard but open it up and its way, way worse... As I'd expect.

You can't link me to someone selling a remap to convince me lol of course they say it improves it.

More power more fuel, any slight amount of fuel saved on your commute is destroyed when you decide to play at the weekend. Don't buy a GTI and/or get it remapped it your looking to achieve even close to the diesels MPG.

If you drive like a granny you might get better than normal mpg for a gti....but then why did you even swap? You might as well drive normally in a diesel.

[Broomy]

I'm in the market for a gti at the minute so this makes for interesting reading. I'm open to dsg or manual but only driven cars with manual transmission so far.

Not really true.
A remapped (properly) vehicle driven in the same way as a non remapped will achieve more miles per gallon.
At full throttle it will use more fuel as injection rates and boost pressures are higher. But the long story short is a remapped vehicle is generally more economicaly.

From seeing Revo Ed30's on the dyno at JKM, the amount of black smoke at WOT would put a PD TDI to shame. Can't see them being very economical. . .

Niki Gower seemed to thinks Revo use the OEM fuelling maps for WOT which gives a very rich mixture. Maintains safe EGT's I suppose but also great for fouling plugs

Back on topic though, I fail to see how a DSG could be better than a manual on fuel. Box is heavier, losses are no better, probably uses "energy" to shift gears, ratios are no more favourable for economy. . .

If your lead footed and drive everywhere in 2nd gear then the DSG shifting up a gear or two will help, but for any half-decent driver who sticks it in 6th at 40mph and feathers the throttle, I fail to see the DSG making the engine more efficient 

Anyone explain?

[RifGTi]

i cant imagine DSG being a whole lot more economical than the manual. Maybe around town it makes sense but then again town driving is not what you guy a GTI for . I gotta agree with xjay on the motoway or any level of constant speed driving shouldnt  be affected by dsg or manual box

i have a manual and round town in busy traffic at this time of year( winter does decrease the MPG) ive had 17-18mpg on the motoway  ive achived 35.5 mpg over the weekend 300mile motorway ( doing 80mph )and 30 mile country roud trip doing 50-60 in 6th gear and thats based of a manual calculation

I do have a stg1 remap by r-tech

I wouldnt imagine dsg being to much different to that

[Black9]

I ran my manual ko3 GTI which was stock engine wise except from a K&N panel filter and my Revo stage 1 eddy with TBE along side each other and found no difference in mpg. If anything though I'd say a manual car driven correctly would have better mpg over a DSG car

[xjay1337]

K04'd engine cars are not as economical as k03s

http://www.tyresmoke.net/forum/topic/52866-why-does-dsg-gearbox-give-better-fuel-economy/

DSG box is lighter apparently. (not sure it is but hey).


And also thinking about it the boost stays up, it just cuts spark on shift, always changes up at the most efficient point.
There's no arguing about it, officially the DSG is more economical. In the real world there are so many variables, tyres, road condition, pressure and tread depth of said tyres, engine health, wind, etc which can effect economy there's really little point getting in a tizzy about it. 

[GrayMK5GTI]

Official figures are wildly inaccurate, as we all know   

DSG box is 25kg heavier than MT. Pretty sure the weights section of the brochure reflects that. If someone can drive economically and change gear at the right point then they should at very least equal the DSG's economy.  Coasting down to a junction on the overrun in gear is what gets your economy up. Doesn't DSG just dip the clutch?

No it holds it in gear. MPG goes to infinite, no fuel.

Same as manual then

[Frodo-anni]

My ED30 DSG returns 36-37.8 over 22 miles to work, 70% motorway at 50-60mph. The drive home is about 32-33 mpg as there is more traffic.

The Leon FR we also have, so KO3 is manual mainly does short town journeys av 26. I can see 34-36 from it on a motorway run, the g/f can never get it to read anywhere near 30, she has lead in her boots
