I recently drove 240 miles from Kent to East Devon. I had plenty of time and was interested in what mpg I might achieve. So, I set the mode to Eco and whenever safely possible cruise control was set to 60mph. I was also very gentle with my right foot! (Yes, I got plenty of looks from drivers on the M25, M3 and A303 as they overtook me!)

I achieved 48.2mpg from my 2.0 TDi engine which has done 8,200 miles.

On the return 240 mile trip, the mode wasted to Eco again but this time, whenever safely possible, I set the cruise control to 70mph and I achieved 42.2mpg. A ten mile increase in speed resulted in a decrease of approx 6mpg. Next time I do this trip I will set the mode to normal and do a comparison to the Eco figures.

Has anyone done anything similar and can show what difference Eco V Normal on a run using cruise control can achieve?

So far have ony achieved 38 mpg over 140 journey. However, when driving in Eco mode the car does not always coast. It will up to around 30mph but then I sometimes have to go 15 or 20 miles before it will coast in higher gears. Garage says this is normal as coasting only works when battery is fully charged. Is this how yours works ?

I am aware of the coasting facility but have not checked to see if it operates in all modes. I will check.

Thank you. I know it only works in eco mode, but cannot understand why it doesn't work consistantly. I only have a week left to reject the vehicle, but don't want to if this is common to all. However I think it could be a reason towards why your fuel economy is so much better.

I'm averaging about 38/39 running about mostly on country road and about 42/43 on long runs at 70 on dual carriageways etc.

I run mostly/always in Eco and coasting comes on quite a lot. Downhill it doesn't always come on and seems to sometimes depend on how smoothly you release the accelerator.

Strangely my fuel economy has got poorer since service was done six weeks ago, was getting a smidge over 40mpg, driving mostly motorway and dual carriageways, circa 600 to 700 miles per week. Now getting only 38mpg at best and while a little drop off may be expected in winter, methinks they may have adjusted something at service or she needs to bed in again and get used to fresh lubricant, etc. I drive solely in eco mode (comfort setting), use adaptive cruise control and she rarely coasts as often she is using the auto gearbox to assist in braking. To me it makes no sense when she decides to coast or not, can be coming down the same hill or allegedly freewheeling towards a town/village with speed limit change... sometimes she coasts, sometimes she doesn't, same stretch of road.

Surely results can only be comparable in the same direction? :p

I'd guess this is by design as you'd end up out of control and be braking a lot more?

Oh yes! This was simply a test to see what could be achieved with the lightest right foot, cruise control, eco mode and a long journey.

Has anyone tried increasing the tyre pressures to improve fuel economy?
Tyre garage specialist previously advised running slightly higher than manufacturer recommendations (which are for comfort rather than any other reason) eekeed out 4-5mpg extra running 2psi more per wheel

If I set the cruise to 65 I can get about 42mpg on a long run, but I have just done a 250 mile trip from Manchester to Devon at a steady 70mph (ACC but roads were quiet) and got 38.1mpg average at an average speed of 56 mph over the distance. I'm happy though as it is nippy when I need it to be (190PS TSI 2.0 DSG 4Drive)

That's good MPG Crumpet
Iv only managed around 34 MPG at the min but the car has only got 350 miles on the clock so all is tight and will probably be better after a few thousand miles.
Same engine as yours.

Very good for the 2l petrol and ACC on doing 70 mph.

Thats good going for the 2l!
I've increased my tyre pressure this weekend to the 38psi it sats on the door stickers will see what difference that makes - they were at 34psi previously

I'm running on 38 psi from day 1
I'm thinking now I probably had a good bit of wind behind coming back from Dawlish hence the good MPG.
I'm towing the caravan next Fri so be interesting what MPG I get.

I have the 1.5tsi engine in my Tarraco and have covered just over 1500 miles now. I have seen over 45mpg on a long run, but generally I get around 35mpg when doing short journeys around town. The trip computer in the car suggests an average of around 39mpg over the course of the 1500 miles, but I have been using an app called Fuelio to track actual fuel consumption. (see pic below). These figures are primarily based on short journeys but give a good indication of the actual economy from the 1.5. Not too bad I don't think.

I'd be happy with that, mine's the same engine, manual too..1200 miles on it. I get on average 39 mpg on a run and anywhere between 25 and 30 in town. I'm disappointed with the latter but given the average speed is low due to the traffic and the winter a/c, heated rear windscreen, blower etc being on i'm hopeful of getting somewhere similar.
