Mpg ?

Hey people, I think Im an economical driver, every time I get in another car I always improve on the previous drivers MPG, yet in my own Freebe it continues to remain pretty crap if im honest..... I have a 2.5 LTR V6 Auto and was wondering what others get with the same engine, Im currently getting around 23mpg but thought I should get a little closer to 30 mpg.

Thanx in advance

Ive just been on Parkers website and they say 22mpg, I would of thought that that is improvable, but not sure how without the expence of fitting a gas tank

The V6 drinks like a fish, it's a naturally aspirated 2.6 litre peterol engine that isn't even as efficient as some V8's. I'm afraid you're going to have to live with it . I get about 30mpg on my 1.8.

23 mpg is bleddy good for a KV6, 30'ish mpg is the norm for K4

It's not the capacity which is actually 2.5L but the auto that makes it drink the fuel. I get 30 mpg out of MG ZS180 which is the same engine coupled to a manual box!!

It is all acording how it is looked after, a good service and tyre regularly checked and also the most important thing is the driver how much lead has the driver in their right boot. driven at 60 insted of 70 makes a difference and also not speeding of from a standstill and things like that when I had my latest freelander 2006 td4 auto I said to my self i am going to start to take it easy . That lasted about 3 weeks now back to normal , but still not a boy racer though !. I get more out of this one than I did my old one , of course it has 120,000 miles less on it and I belive they are slightly better tuned , or is that just me , getting in the 30's anyway.
And auto's always take more fuel one problem is the extra weight.

pulling a lighter car in front wheel drive

23 mpg is very,very, good for a KV6.
You must be driving it very, very, gently.

Some folks get around 17 mpg.

But that's why they are cheap - so that you have some dosh left to buy fuel with.

I can get over 40 mpg without even trying on a long motorway journey in my TD4 auto.

It's around 200Kg's lighter, compared to my V6 Freelander in which I mostly potter about in. I drive the 180 in a much more spirited manor! I get around 23 mpg out the Freelander!! The KV6 is a lovely flexible engine that the Freelanders auto simply doesn't make use of. It will pull from 25 mph in 5th which is just on 1000 rpm and there is never really the need to rev it above 2500 rpm to make quick progress!! So imho it's the box and KV6 just aren't a good match for best mpg!!

Is there a way to adjust the kickdown or change the gearing to optimise the match?

Sadly there is'nt as it's a computer controlled system which I reckon is more suited to the 2L KV6. It is adaptive but only to a point and can't compensate for the 2.5L's extra torque. I was looking into converting it into a manual a while back but sadly it's not a simple job and tbh for the 3 or 4 mpg saved it didn't seem that important!! I reckoned it would be better to improve the breathing so the engine efficiency first. This was all before the head Gasket let go which has taken priority!!

My v6 usually does 18mpg on 30/40mph roads and residential areas. At a steady 60mph constant I can get 28mpg. That’s feathering it and filling up every day when I did a constant long trip each day for a week. Recently mpg has been as low as 16mpg constant. Really struggled to get it into 20 something, even on the motorway. 22 was possible but a struggle. This has now been resolved and I’ve just managed 27mpg at 60mph.

I think the gearing on the v6 is good. Everyone who has one likes it and the way it drives, but not the mpg. It’s what you have to put up with when you drive a furra bread. The transmission is geared down too so there’s more torque coming out, but that’s only felt when towing or going up 45 degree slopes.

Ah, the gearing on mine dunt make sense til I get it orf road.

then it can traverse anything without struggling.

it's a play off between performance and off road ability.

It's a shame it didn't get an off road and on road shift pattern.
For the road it's lower geared than the engine can handle. The 2.5L engine's torque curve is lovely and flat. There is more torque at 1500 rpm than the 1.8L makes at any speed so it can do with a bit higher gearing!!

Thanx for your comments, The engine seems to be really well looked after and is gleaming, lots of oil changes seems to of done the trick, I have got the car to 25 mpg but that was being very slow and cautious..... Some one has already brought up what my next question was going to me.... The Engine has loads of grunt but the auto box seems really poor, going up hills seems to be an issue for it as It will not settle in any one gear and is very sluggish to respond, where the engine jumps into life and is ready to roar, I dont know much about how an auto works if its a mechanical operation or do electrics play a part ? If the later is there an update for the softwear

i agree, lower and higher selectable would've been nice.
but it would, of course, been made by Rover so would've been more trouble than it was worth

It's ecu controlled for shift points and it's adaptive so will learn your driving style over time. If the changes are sluggish it may well be overdue a fluid change?? The engine is a lovely power unit while it works but is prone to water leaks in the thermostat area which allows the cooling system to airlock the result of which is more often than not in HGF!! It's not bothered be oil changes and is happy for them to be carried out at 12K intervals. The same KV6 in Rover cars get them at 15K but it's wise to use a full synthetic!! Be warned though make sure the coolant is kept topped up

Your driving style is quite probably completely different from the last owner.

You can reset this adaptive learning ability back to square one simply by disconnecting the battery for about 10 minutes.

Be sure you know any radio codes before you do it though.

I was sceptical of this but discovered it was true when i fitted a new battery a while back.

Like a completely different auto-box for a while until it 'got to know me again'.

The engine and gearbox ecu's are adaptive and will learn the engine gearbox and your driving style over time!!

Well some one has already mentioned what was going to be my next question..... Is the a way to improve the gearing as the auto box is very poor, especially going up long hills. Many gears are called for but few are chosen, and normally the wrong one
