...sorry but I just can't believe figures of 11L/100klm for a LS,or any V8!!

My X Trail does that and that is believable.

Our SCharged D1 3.9 tow truck often returns 35L/100klms when towing. It's on gas and has 130kw at the wheels. We get used to it because it can tow 3.5t with ease, legally which camrys and x trails can't, all day every day. You can't have it all, I agree with Blitz

Hello INter674,

My 4.6 Rover V8 has delivered 9.3 litres/100km on two occassions running from Bathurst to Sydney, 100 to 110kph where speed limits allow. Twin SU carburettors too..:) The engine is in a Rover car with a mass of 1300kg, so somewhat lighter and much more aerodynamic that a LR/RR.

I bet it doesn't get that on the way back to Bathurst though. :D

haha, my 3.9efi Range Rover Classic 93 with Unichip used exactly 60 litres for 550km couple weeks back which works out to be 10.91L/100km. Sydney to Brisbane using 110L. (lots of stops along the way/roadworks) and thats with a slipped liner. lol

Agreed, entirely possible Ron, My worn 3500S got to 25mpg, (once...:)) Those SU's are far more efficient than fuel injection in certain circumstances IMHO. A much underrated carb.

OK maybe for that configuration of weight/aerodynamics/tuning/air temp etc etc, but not in general, for vehicles generally fitted with V8s, and the way they are usually driven/used. Anyhow, let's not start anaother debate on fuel consumption because I know a guy with a diesel Hilux (2.2L I think) that averages 25L/100klms...reason being he thrashes it to keep up with the traffic!! Horses for courses...

They're reasonable figures for an old tech engine but its not just lighter weight and aerodynamics which are relevant- lots of extra gears churning heavy oil inside transfer cases/bigger gearboxes/extra diffs makes a huge difference. The rotating mass of bigger wheels/tryes is also significant.

Nice, Ok I give up. Can we swap as our last figures were 58L gas for 190K's (towing 3.3t but):o

Cool, I'll have your scharged 3.9 and you can have my stuffed 3.9 with slipped liner...... maybe? :p

Some of use facts, I wouldn't expect an average of 11's either, that was in an SS ute, not a rover, I'd be expected 15/6's as an average overall for a rover with LS1

Yep, our Statesman 5.7 averages around 11litres per 100kms at 115-120kmph. At 100 - 110 can get as low as 10. On long trips of course. Got down to 9.5 once on a trip across Nullabor. Depends on a lot of factors, wind, load, up hill, fuel quality/type. Of course it can do a lot worse when pushed hard.
