Scotland 2006 Discovery 3 TDV6 HSE Auto Zermatt SilverDiscovery 3

you see this is what confuses me, if you let the engine wind up slowly it takes longer to get to a cruising speed. Stomping on the gas (within reason) surely gets you to a cruising speed quicker. So is it (in MPG terms) better value to take it slowly to speed i.e. travelling less distance in the same time or is it better to travel greater distance in the same time period. So if you were using a cup of fuel (I wish) which driving option over the same distance would use the most fuel.

I am stil struggling to see where the torque comes into this Brian (I never was mechanically minded) but I recall in my old days on the farm always being taught to high rev the engine into the gear change on both landrovers and tractors.

So if you forgive my ramblings there are clearly some guys & gals getting superb MPG, what is your driving style that gets you that? High revs or low revs? and where does the torque come into it?

Simple, use the torque which comes in around 1200 rpm and drops off severly at 2200. After that you are just making noise and getting no where. Sort of boy racer style. Landies are built to tow upto 3.5 tonnes and need all the grunt at the bottom because it would not move anything with high revs. Simple.

I average 29 to 32 mpg in a similar location to yourself, being up the road from you.

I starte this in the early days of the site and some guys took it on board and it does work. I actually earn my living getting economy out of fleet drivers.

And it does work, but you do have to think a bit about it initially, particularly if you have an auto

Will give it a go and see what happens. I am currently doing 25mpg measured (rather than instrument) so will report back in a couple of weeks.

Having read Brian's post on the torque range, I fully intend to try and stick to it.

Just filled up as part of the test.
Old style driving was exactly 24.68mpg. Thud Thats is if I have worked out my conversion correctly, put in 45.5 Ltrs which I think is 10 Gals exactly. Which makes the rest simple as I had done 246.8 miles.

Hope the 'BN Method' inproves this for me Smile

Jim, it does work, but it is hard. I have done it most of my life as a business. Full to full is the best way of working out your mpg. I think you will also find, I do not hang about as Slimer found the other day, so you can get going once you know where the torque is most useful. Best of luck.

Thanks Brian, I am certainly looking forward to the results. Have already noticed the improved accelleration changing between 2000 and 2500 revs, working the gears. I guess that this is how LR expect slightly better mpg from the manual over the auto box.

It's not really that Jim, you are just using the power where LR designers put it at the bottom end. Have you tried the brake test yet?

Bn what is the brake tst? I am glad to say I drive the way you recommend, when my husband drives it which is not to often, he can not get used to it and complains about the lack of power as he is driving it like a performance car. he remains impressed with it on long journeys, not around town.

The brake test is to simply show just how much power the D3 has. It is very simple. Find an area that you can place the car in low range, level or uphill. Put the car into 1st gear or lock into 1 in an auto. Then DO NOT touch the accellerator and let the car move away. Keeping your foot away from the gas. An auto needs a bit of gas to move off then off the gas as it moves. Now press the brake pedal gently and increase the pressure. The car will alter the power automatically and you will find it is very difficult to stall the car. Take your foot off the brake just before it does actually stall. You can do this uphill by the way, not just on a level ground.

Then ask hubby to try that in his sporty cars Very Happy

Jim the bit that is clever, even if you go up a steep hill it will work. The car is really clever.
