Stupid MPG Question.

We all know that MPG is determined by alot of factors!

Typically what average mpg to you get on a 3.0L lets say on motorway or A roads?

I only ask because originally I wanted a 2.5 auto and now might change my mind for the extra ponies the 3.0L offers.

Thanks.

Regular cruising on the motorway mid 30's (I tend not to speed on the motorway, it's mainly the slip roads that I use the power). 40 is possible if you're sub 70 and in clear traffic. Town and traffic is a killer for big engines.
 
Around town youll get 20-25 driving normally
On motorway youll get over 40mpg at the right speed around 65mph mark

I did 130 mile trip the other day 70% motorway rest where welsh fun roads and got 34mpg average

which if you think about it aint bad for 260bhp engine haha
 
Lots of people keep saying about this 40mpg on the motorway but I never get it. Stuck to 70mph the other week on a flat section of motorway for about an hour, and only go 32mpg.!! I'd reset the computer at the start also.

Do get 22-25 around town booting it thou, so I'm happy with that.
 
i recently drove from Belfast to Galway (230 miles) via motorway, lets say I wasn't hanging about... and i averaged 34mpg. I was quite happy with that! I live and work in Belfast so most of my driving is in or around town and I average between 27 - 29mpg...
 
to give you a rough idea i put in £30 of 99 ron the other day computer said id get 180ish miles from it

i suppose it depends on a lot of factors youll easily get 30 mpg average out of a well looked after 3.0

Wheels will make a difference to 17s vs 19s ect weight of them tyres ect ect
 
I've noticed it does seem to vary with lots of people. I have a standard 3.0i, and daily to and from work driving in the city i get between 29mpg and 33mpg, depending on traffic. Motorway driving i always get 40mpg doing a steady 70-75. On my last motorway trip i reset the mpg counter as i started and got it up to a superb 45mpg!
 
I recently picked up my Z4 in Germany and had a 600 mile drive back to Denmark. Cruise control at 87 mph and mpg average was 30! Ok I guess for that kinda speed.

On a daily basis I'm at 23 mpg doing 80% of my driving in the city and the rest flooring it on b-roads :D
 
Just as a comparison.my friend has a 2.5 and he averages about 27 mpg on mainly A and B roads driven normally..
I have a 3.0 and average 32mpg ..

This was the main reason I got a 3.0 more power and better economy.. Which really annoys my friend.:thumbsup:
 
Yep, 40+ on motorways, typically the trip is at 35mpg when I fill up after mixed driving.

On our 3000km euro roadtrip last year it AVERAGED 38 including spirited mountain pass driving.

3.0i manual.

It really is a fabulous engine. Absolutely no need to even consider the 2.5l - just go straight for the 3.0i or 3.0iS
 
I use mine as a daily for a 40 mile trip to work and back, cold start queuing traffic for first five miles then some motorway sprinting then some soft nose to tail for last few miles - then return journey in the evening. These journeys give a constant 32mpg 3.0si N52

Occasional motorway trips to London 70 to 85 varied speed produces around 37 sometimes 38 but never more

Never seen 40 ever under any driving conditions

I do think the mileage I get is fantastic for a 3.0 265 BHP car though

Ps the above is standard fuel not 99

Yorkie you need to get a tune. My MR gives better than that, on Super, when I'm nice to it.

So the 3.0 gives better fuel economy then the 2.5l auto???

Hard to believe but you guys know your stuff!
 
even if the 3.0 has come into your mind never will anything else do youll always want the extra power with similar running costs win win
 
You can get 30 even 40 out of the 3.0 litre - but you wont! :evil:

On the transit up to Scotland (steady throttle) for the last Forum hoon I averaged 36mpg at legal limit +10%+1 (included 60 sections)

When I use my Zed for the weekend with my wife it can drop to 23mpg

Never used it for daily commuting but I think the differences between 2.5 and 3 litre will be minimal - both 6 cylinders. If you want economy go 2 litre 4 pot. Auto will effect mpg.

:driving: :thumbsup:
 
Just buy one I love my 3.0 Auto and still do after 6 years of ownership just wish there was less old bill and cameras about and I could drive her like I used to do :cry: as for mpg I drove at a steady 80-85 and was told I was getting 33 mpg around town and A roads 20-25
 
Thanks for all the advice, very much appreciated.

I suppose I have an ounce of trepidation about larger engined cars, I brought my mk2 tt 3.2 on a whim and suffered majorly on the fuel running costs (<20mpg).

Not because I couldn't afford to run it, rather I'm just a tight git! :roll:
 
Just come back from a 1600 mile trip around the Highlands in my 3.0i which involved lots of spirited driving b2b minimal motorway and it worked at around £320 in petrol. I think the highest price I paid per litre was £1.45, do the maths and it comes out at 33mpg, the car always surprises me on how economical it is.

No other engine in the range worth considering imo. :)
