This may be the first LR I have owned, and I may have been a little naive in my fuel consumption expectations with the S/C, but I probably have more LR product knowledge than most on here

I suspect hell will freeze over long before I have another diesel car myself though... I would buy a petrol Freelander 2 in preference to a TDV8 RRS any day In fact, one of the reasons I left the Porsche brand after 8 years in 911s was their decision to sell their integrity down the river with the launch of the Cayenne diesel.

I love Supercharged petrol engines, and if I can't afford to drive it properly all the time, I'll just do my Granny bit for a while and save up for the odd days of indulgence!

(It still sounds pretty good at 1500 rpm anyway )

OK, perhaps I should have said 'recent' LR product knowledge (i.e post-BMW)

But seeing as you asked...

Series 3
67hp
2250 cc
3 bearings until 1979

Ok SW, almost there but your forgiven

if you wanted to be picky it's 2286cc - and no I am not a tree hugging enthusiast and definitely do not have any facial hair

Unfortuantely its a sad case of only ever having owned L/R's or R/R's

2006 Range Rover Sport Supercharged Zermatt Silver

I've had my Supercharged RRS for 3 years now, and the average fuel consumption over that period (35,000 miles) is 19.2mpg, but I do tend to do a lot of motorway miles (stuck nose to tail at 70-80mph), where I get just over 20mpg. If I don't drive it on the motorway, I get c.17mpg.
All this is on regular unleaded.

I thought about swapping it for a TDV8, but I would need to put at least £30k towards it, and I can buy a hell of a lot of petrol for £30k (and still have that great noise)!

Hope this helps.

Bob.

Cheers Bob,

If I can get close to that I'll be very happy! I think mine must be over-fuelling as I only get 18 mpg on a level motorway with the cruise set at 80 mph and I'm sure it should be in the 20's for that. In theory it shouldn't use any more than a TDV8 at a set speed as weight, friction and aerodynamics are the same for both.

It's booked in for tailgate rattle anti ARB bushes soon, so I'll get them to check... Wonder if the S/C bypass valve is sticking or something?

A litre of diesel contains more energy than a litre of petrol, IIRC. Hence the better mpg figures, in general. Been a long time since I was at school though, so could be wrong, lol.

Interestingly, if I use cruise control (which I don't very often), I always get worse fuel consumption than when I use my right foot!

Bob, exactly the same happens to me with a diesel - I think its due to the engine management constantly applying the brakes on downward hills and opening the throttle hard on hills to maintain speed (instead of feathering it)

That makes a lot of sense. Going downhill, the car slows far quicker than if you were just coasting, so it must be applying the brakes. What you would normally do is use the speed going downhill to carry you up the other side. The car brakes downhill, then accelerates uphill (sometimes changing down a gear or two).

What I find particularly frustrating is when on Adaptive CC, as you come up behind a lorry on the motorway, the car slows down (as it's supposed to), but when you pull out to overtake, the car can change down 2 gears to quickly get back to the set speed. If you were doing it yourself you would judge it better, and keep it in top gear. That's why I don't use CC very often.

You will do if you leave it in 'D' as it keeps changing gear up hills to maintain speed (and to speed up again every time a slower car has reduced your speed via ACC), so I use Command Shift and stick it in 6th gear to avoid that. Still can't better 13 mpg overall average though.
