Just covered 300 miles now in my new 3L TDi S line Q7, average over 300 miles was 16.3 mpg. I've been told it will improve slightly as the car slackens off but this is worse than expected 23-24 ish !

Good job I work offshore on the Oil Rigs for TOTAL, keeps the share price up !!

I certainly hope it gets better or else would have been better off getting cheaper petrol version.

A guy came in our shop the other day with a 4.2 petrol and he says he has not seen double figures on the DIS yet, so I guess 16mpg for such a heavy car is not too bad?

I only got 26mpg from the 3.0 litre 535d, and that is 2WD and a lot lighter, and I got 21mpg from the ML270cdi, so I would expect around 19mpg from a Q7 once run in.

It all depends on your driving. I had an allroad 2.7 TDI as a service loaner and could get the instant mpg into single digit figures easily, yet a longer run (30-40 miles) on country A-roads was turning an average of about 33 mpg. It's all about getting up to 70 or 80 and staying there.

Colleague at work has a 2.7TDi A6 and he's getting less mpg than I am, only just starting to scrape 20+mpg

The courtesy 2.7TDi A6 did no more than 13 on the day I had it sekret.gif

And we wonder why environmentalists hate 4x4s coffee.gif

Because they're crazy? The S8 averages 20 mpg, and if I changed it to an allroad 2.7 TDI, I'd be averaging 33 mpg or better, yet I'd probably get more flack for the allroad.

Of course, if I hated the planet, I'd buy a Prius and then run so many miles on it that the batteries needed replacing every year, at great energy and pollution expense. coffee.gif

Don't know where you guys are driving or what type of boots you are wearing but although I get 17 on my 7 mile drive to work (hilly terrain and slow speed for three miles before I hit the main road) I have averaged 22.7mpg over the last 8500 miles and can get 26-27 on a trip on the M1/M62. I have a reasonably speedy boot but try and keep away from the brake! Q7 3.0 TDI. S4 cab gives 21.5 average with 24.5 on motorways.

I got my 3L TDi S line Q7 on 1st March. It has done 800 miles. So far consumption is around 24.5mpg on a variety of town, running around and motorway work. Not as much as I had hoped but nowhere near the figures above. I am not a slow driver. For comparison my E39 523 Touring (2.5 petrol) averages 27mpg and even does 25mpg driving 40miles into Westminster.

I have noticed two things:

1. Consumption increases significantly above about 80/85 mph

2. Shell V Power Diesel has a marked (positive) impact on both economy and performance.

I expect the fuel economy to improve as the engine beds in - my BMW is better now with 180,000 on the clock than ever before
