Hi All,
Our D3 TDIV6 has not lived up to Land Rovers published data on Fuel Economy.
Land Rover Urban L/100km: 11.5 - We are getting on average 15.5
Land Rover Extra Urban L/100km 8.2 - We are getting on average 10.9
We have taken the vehicle to the dealer, but they state there is nothing wrong??
Any assitance would be helpful.

In the UK Land Rover quote overall fuel consumption for the D3 at 30 MPG. I dont know anyone who gets close to that. The manuals seem to average about 27mpg and the autos about 23 mpg (plus or minus 2mpg depending on conditions). Afraid the manufacturer's figures are simply wrong (arguably mis-selling !) and we need to accept that moving a vehicle of this weight is going to burn a lot of fuel. Disco 4 TDV6HSE

During the warmer weather (I don't think we really get hot weather over here  ) I averaged 28-30 most of the time and achieved over 32MPG on long runs. Since the colder weather has set in and the FBH is getting a lot of use this has dropped by about 3-5MPG (depending on how cold it is basically).
So yes the claimed figures are obtainable but not if it's too cold The End

Agree with Slimer here... good if the FBH is not kicking in.

I regularly get 28-30 from my auto with less in the winter. It really comes down to how you drive it. I know I mention it a fair bit but BNs advice took my cars economy right up. Sure if I want a bit of fun I won't achieve as much or sit at high motorway speeds (80-85) but at least I know how to get the best. So by getting the autobox to change up at about 2,000 revs really does make a difference. Roundabouts are the big killer though especially those on dual carriage ways.

The quoted mpgs are based on standard tests. They allow like for like comparison between different vehicles driving a standard route. You have to remember that it is in the interests of each manufacturer to ensure that the test yields the highests possible figure, so the driving style adopted is one that minimises the wastage of fuel. It would be extremely boring to drive like this in the real world, which is why the stated vales are seldom achieved.
Many other factors that are not directly attributed to driving style can affect real world MPGs, for example the weight of additional passengers and equipment, the use of air conditioning equipment, the use of any non-essential electrical equipment (e.g. lights during daytime driving) that imposes additional load on the alternator, driving with windows open, accessories that increase the drag factor (roof boxes etc). Additionally, automatic transmissions give lower fuel econony compared to manuals.
Accordingly, the standard MPG tests will be carried out on a base manual model (no excess weight) with the air conditioning system, FBH, electrical accessories switched off.

Mine was doing 10,5 l/100km in the summer (only extra-urban use), now is set to about 11,7 l/100km. 
Lots of pre-heater fuel burning, I suppose.

There are actually 2 different sets of figures provided for the government tests & published by LR - for the Manual & Auto - and the Auto is several mpg worse !! A lot depends on driving style (use of hgher revs etc as BN details) but also the routes you drive - if you are running short trips, especially on cross-country routes then expect sub-20mpg with an auto Diesel as the engine will have barely warmed up, FBH will be running & you will be accelerating/braking throughout
