Ok maybe, maybe not but I'm turning a blind eye and calling the consumption computer correct at 20.1 mpg U.S.. This was over a 300 mile trip. I can also manage 16 mpg in country/suburban roads. So much more reasonable than what the EPA stats say. Not bad for a 5400 lb urban tank.

That would be 24.12 mpg in proper manly gallons  2008 MY Supercharged

I got 32mpg out of the L405 4.4 SDV8 on a long run (5 up with a boot full of stuff). I was more than keeping up with the flow on the motorway too. Rather amazed me.

32 mpg imperial in diesel? Thats about 27 mpg US. Wouldn't mind having a diesel here. IIRC we are just starting to get diesel RR. Premium petrol and diesel cost about the same.

On the 520mile round trip when we did the Coast to Coast off road trip I averaged 9mpg IMP

I dream of 20mpg  Pete

How many are not running diesel?

If I am not bashing the local hills I get 22mpg and have had 25 on a good run in the vogue Petrol,uk gallons!!

i've got the BMW 4.4 petrol engine. If i reset the trip meter and do a constant 65mph i can get it to read 25mpg without any problem. Average for town driving is about 16mpg i think.

Good to here. So my next goal is 22 mpg US. If I can get my mirrors to fold in....

yeah, when i did the steady 65 i just set the cruise, so the car does it it's self.

I think 25mpg (imp) is about as good as it's going to get, but i didn't really buy it for economy, i could have kept my Diesel Jaguar for that (60mpg)

I agree I didn't buy it for the MPGs but I find it Interesting to see just what it can do. I was going to go the Jeep Commander route at first. But after talking to owners real world gss mileage and repair costs were the same as the RR and not as good looking.

I reset mine the other week and after a 60 mile round trip it showed 20.1mpg.

It's gone back down now but I didn't realise the first character could even go to a 2! Dan
