Title: long term fuel consumption
Post by: nigeldodd on 23 January 2018, 14:16
I should have chosen to untick the brakes option when I specified my Mercedes E320 cdi 18 years ago because, by not using the brakes, I can get 40mpg out of it.

I expect my driving habits will change when that car is replaced by a gti7.5 pp in a few weeks, but I'd be interested to know what long term, and max and min over short term, fuel consumption the connoisseurs of this board get. Please.

I've done 11k miles in my gti pp and long term is 31mpg. That was sitting at 34 before the cold weather kicked in but I have had 47mpg on a long drive. I personally haven't noticed the difference in my mk7 gtd from before and actually much prefer the GTi.

Depends entirely how you drive it.

I can get 30 - 70mpg on a trip; 35 - 65 mpg over a whole tank of fuel in my GTD with DSG.
(35mpg chasing top speed on Autobahn wherever possible, 65 racing lorries and never ever using the brakes).

Realistically in a PP.... 28 - 40mpg, depending on driving profile and your right foot. Maybe 50 on trips if you really just cruise it alongside lorries for 100mi on a motorway (and never go near the throttle).

Have had my mk7.5 gti pp dsg since mid November 17 and my average mpg is 32.3 many short journeys driving mostly in economy mode, had some fun in sport mode and have also used normal mode. Cold weather, short journeys,  new car needs to bed in and getting used to driving my new car all contribute to my average mpg. I would expect average mpg to improve when the temperature improves in the spring and the other contributing factors are taken into account, hopefully to about 40mpg. Total miles covered so far 650 miles.

My best mpg was the journey I did to Skye and that wasn't just pootling at 50mph. Lots of overtaking etc etc and got high 40s.

Had the GTI since October. Done around 1800 miles so far. Mainly short trips around London and few further out. Switched between ECO and Sport quite regularly. My best mpg so far was on a long drive and managed to get 38mpg whilst driving in Sport mode. So I'm guessing it would've be allot better if it were ECO.

I've since fitted a pedalbox, so mainly drive in Normal mode and averaging around 32 mpg.

ECO mode won't save you much... it adds throttle deadness, slows down ACC acceleration, reduces the aircon and turns off the cornering lights. Oh and with DSG enables coasting.

Honestly, in most situations I'd be surprised if it adds more than a couple of MPG, possibly even negative to MPG if you aren't cruising on the motorway on ACC and using more throttle input to get over the dead car feeling...

You can set just engine to 'Eco' and leave all the rest on normal or whatever you prefer.
I have mine set up to Eco on engine and ACC, steering and dynamic cornering lights to Sport and AC to normal.
Easy enough to flick it to sport for overtaking, tbh even with engine in Eco you'll leave 99% of cars behind you.

Tried ECO once and hated it, my OH's 1.0 Lupo was more responsive :rolleyes: I can't even see it making much difference to mpg, that's down to driving style. On the motorway or poor conditions I use Normal and my pedalbox in sport, otherwise Individual with everything set to sport except for steering which is on normal.

MPG wise, short commutes (5 miles) I get between 28 and 33 temperature depending, steady long runs 45 to 50 (but more often around 45) and long motorway runs 40 to 45. Very happy with that :smiley: My previous Audi varied from 26 to a max of 33 so a great improvement and so much more go too :evil:

A 1.0 Lupo is already overpowered for London traffic thou :D

I think some of the wolves might have escaped from ours :rolleyes: We get really bullied by the bigger cars :cry: :laugh:

2014 Gti manual with PP, long term = 36mpg

I've had my GTI PP for just about a year now with about 17k on the clock. I've been consistently getting 36-37 mpg over the 100 hour long term measurements. My commute is fairly long and partially over motorways. The route is pretty sedate due to the traffic. Only about 5% of the trip can really be described as spirited.

Pretty much exactly the same. I buzz around on weekends, but it's all motorway during the week. She surprised me this morning and managed 46mpg.

I usually get a combined figure of about 34 -35. On a longer run it climbs to over 40 mpg but then tends to drop again in town. I would rarely get under 30 mpg unless the traffic is severe.

Dont see the point of eco mode on a GTi. I use normal or sport. Average around 32. Got 40 on a long motorway run.

Over two years ,and calculated by brimming the tank each fill up , I get 36 mpg. Get 40 on a motorway run though .
