I have had my new rrs 4 weeks now and the average fuel consumption has been between 22-24.It is mostly driven around town but had a long run (250 miles)last week mostly on motorways but the consumption was the same.Will this improve as the engine runs it?.

Sorry, nope! FF 4.4 V8 Soooo looking forward to this bad boy
Ex 2006 RRS SC - garbage
Ex 2016 135i M Sport - dream car
Ex 2003 RS6 Avant - piece of cr*p
Ex 2014 320d X Drive, M Sport Touring - ok I guess
Ex 2007 RRS TDV8 - bloody loved it
EX 2007 FL2 XS - not so bad

22-24 is normal for the diesel RRS - outstanding if it's a petrol RRS though!  2005 Zambezi TDV6 - Gone but not forgotten
2009 Alaska TDV8 - Gone and much missed.

Also if it is driven mainly in town the gearbox ECU may need some re-educating to make it go into 6th gear if you don't get the speed above 55ish most of the time. Once you get up to 55/60, move the gear stick to the left into Sport mode and then notch it forward once and the digital readout on the dash should show 6, come back out of Sport mode (which locks out 6th) into D and she should stay in sixth. Everytime for the next few runs where you are getting up to 55, try manually shifting into 6th and then the ECU will get the message and do it automatically. I had this problem when I took delivery of my FFRR, it had led a life of indolence trickling through London traffic for a few months and wouldn't go up to 6th with out manual intervention - now it shifts up by itself at 50-55mph with no manual shifting 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it
2018 Melting Silver Mini Countryman PHEV - soon to be replaced
2015MY Corris Grey SDv6 HSE Dynamic, the best car I have ever owned, totally reliable only a cou0le of rattles in 3 years, now no longer in my care
Also in my garage is a 1996 TDi300 Defender 90 County HT made into a fake CSW

I'm getting about 32 mpg on a long motorway run but about the same ie 25 mpg running around town. MY2011 HSE Santorini/Ivory/Piano Black/Privacy Glass/TV .Sadly gone.
Audi A5 Sportback Black Edition 3.0 tdi quattro S Line

Is it a new one??

If so you could be getting higher returns.

Mines floating around 27/28 at the moment - but its slowly rising as it increases with miles - book for the motorway is around 34, im expecting around 31/32 Mike

2014 Facelift Discovery

mine is average around 25.8 mixed miles done about 1500 miles. SVR 2018 in Santorini Black.

My average over 1500 miles on A and B roads and round town, no motorway driving is 27.5 mpg.

Of course it would help if you mentioned which year and model you're referring to.

Sorry tigertrout, didn't read the heading. Off to Specsvers once I find my glasses.

Next time you go on a run, reset the computer and you will fine it is doing more mpg, but if you leave the computer it averages the mpg over you entire journey a+b roads + your motorway run and you will find by resetting your computer before you join the motorway it gives you a better mpg figure as it is averaging your new reset at higher speeds.

....... and don't start checking up on the fuel computer, wished I hadn't!

I know there was a thread about this some time ago but would like to hear anyone else's recent experiences, just in case something is wrong with my RRS (3.0D 2010). It all started for a few months back after a trip to the Lake District that used more fuel than I had expected. Since, I have been comparing the average mpg of the trip B fuel computer, reset on each diesel fill up, to the actual miles done between fill ups and the actual diesel used.

The average mpg on the fuel computer is consistently 6mpg more than the actual mpg............ is this normal?

On mainly motorway I get 25.4mpg (between 70-80 mph .... at least that's what the speedo said!) but the fuel computer average read 31.4mpg. Around town and short journeys, the actual was 20.6mpg but the fuel computer showed 26.4mpg.

As someone else said, you don't buy a car like this and start looking at fuel consumption, which I accept and I don't expect to get the manufacturers quoted stats but I do expect Land Rover to build a fuel computer that doesn't lie!

I came from a BMW M5 so not used to high mpg ....... but at least the fuel computer was accurate.

Is this just my RRS?

agreed, the mpg on the computer can be slightly optimistic....

They vary... but most are 2 or 3 mpg over the true value... RRS gone
Audi SQ5...Gone Audi Q7 S-Line 240 3.0TDI Gone
Audi A6 Allroad Sport 270 3.0TDI

Its all about the way it calculates it to how you calculate it using actual values

Ive had a day returning around 28.9 Mike

..... well my RRS certainly doesn't calculate it on fuel used and miles driven!

I would not expect the fuel computer to be consistently 25%-30% out over a tank of fuel ..... no point in having one. It's also not a matter of sometimes it's more than actual and sometimes less which eventually averages out. Not in my case anyway.

Ahh, !  RRS TDV8 (loving it)
Suzuki Bandit 1200 (For when the suns out)
Nissan 350z GONE

Its mainly because they use percentage of fuel in the tank based on the inaccurate float

Similar to planes which is why us pilots dont trust fuel guages in aircraft and do proper maths (ok get people to do proper maths) Mike
