After 2200 miles, I can only say I am very disappointed with the MPG I have experienced with my GTD. My LTA is sitting at 36.7 mpg with mixed driving of dual-carriageways (100 mile round trips) and town-driving, someway short of the book combined figure. I know this figure or anywhere near is unrealistic, however I feel that something around 45-50 mpg should be achievable. The most I have soon on a journey was just under 47 mpg, driving with extreme care.
The cat has been into the local delership and details sent through to VW HQ in MK and to Germany and they have told me there is nothing wrong with it. I've also had a long conversation with VW UK Customer Services just thus morning about it, upshot is the car is going to another dealer for another "check-up" when I get back from offshore and have also be offered a like for like extended-loan car to see what MPG I achieve driving it......
I rounded the conversation off by stating "are you telling me that my upgraded 1995 MK3 Golf TDi is more fuel-efficient than my 6 month old MK7 Golf GTD and engine-technology has not advanced in 20 years?", a car than until it was recently sold, could achieve 55-60 mpg combined every single tank of fuel with exactly the same type of roads and driving style....they didn't and clearly couldn't offer a reply.
I have found the MPG to be no different, poss. even slightly worse than in Eco mode than when in Sport. Having rear all the comments from other owners on the figures they have experienced, virtually all seem to be achieving higher MPG's than I am.
One of the main reasons I bought the car was the great MPG figures, and this was also quoted by the salesman as being one of the attractive features. However, after 2200 miles, I would be inclined to disagree. It's a real shame, but the bottom line is that if I thought I was going to get such low combined figures, I would have bought a GTI or R.
