Well, had my car for 3 months now, and thought id check, see how the fuel consumption is, and also see how accurate the trip computer is, as they are known to be very optimistic

322.6 miles

28.75 litres of fuel

Works out at as good as 50.4mpg, which is alright considering the way the car was driven sometimes

Trip computer said 51.2mpg

Cant argue with that

I think the trip computer is a little optimistic with it's readings, but not by too much.

Has anyone noticed how wildly inaccurate the fuel gauge can be? Once I fill her up, I can get upwards of 100 miles without the fuel gauge even moving. From full to about half a tank I get about 300 miles. Then the needle drops like nobodies business, until finally moving at a more uniform rate... seems strange.

Anyways, I've only had the car 7 weeks, but calculated that I'm getting just over 50mpg, which I'm happy with. I'll have to remember what the trip says next time I fill up to see how (in)accurate it is:thumbup:

Cheers, Matt.

There was talk of them overreading by as much as 10mpg on some vrs's... :eek:

see here - mine's out by about 15mpg, which is around 30%

I found the vRS to be not as good on fuel as I was expecting. The PD100 that a mate owned was giving him fantastic economy so I was expecting the vRS to be not too far off, but I seem to average late 40's most of the time.

Post 40k service and new EGR valve it's a bit better, creeping towards the 50mpg mark without trying too hard, but the 60mpg that he could get in the PD100 is a bit out of the vRS's reach under normal circumstances IMO.

That said, I think I could get 60mpg but I'd have to sit at 50mph from Lands End to John 'O Groats non stop.

I always get 45mpg no matter how I drive. I do not understand how people can get 50mpg+. My trip compute is always saying 55mpg so it overestimating big time.

When people are getting 50mpg are you driving really slow? or is there something wrong with my vRS?

My 50mpg was, id say, 70% motorway driving at 70-80mph

The other 30% was 'enthusiastic' A roads and town driving

I bought this up a while back.

the answer is because fuel tanks are tapered.

Mine works out about the same Mikey, pretty much the same style of driving Dundee - Edinburgh and back 5 days a week.

Also a bit of 'Brisk' A roads and town driving

As i have quoted on other threads, mine reads approx 35% over. After 30mile commute it regularly reads well into the 70s and yet i have never got over 52mpg brim to brim.

My best mpg on a journey was 82.3 after a 100mile motorway drive at 70mph. if it were correct.

vRS fuel economy with a cold engine is appalling, and it takes 20 minutes for the engine to warm up. My guess is most of your journeys are short ones. Or your handbrake is binding.

In the year and a half i've owned the vrs:

Total Miles 37528

Total Gallons of Fuel 811.49

Average MPG 46.25

B road 22 mile commute each way to work plus a few trips down the M1

Quite impressed with the economy/performance balance

Mid forties for me too, still haven't had its first service yet so maybe things will improve after that. But in fairness its over 15mpg better than my last car, so I'm happy

So, its you i keep seeing on that road!

Normally 25 mile motorway 80ish then 25 mile A and B road 60ish but a few hills. I do drive "briskly" but have even tried driving slower and it never went above 45mpg so i just nail it now seeing as it is the same mpg!

i think i'm averaging around 40mpg also, not as good on fuel as i thought but then again i have a heavy right foot.

Averaged 46mpg in the last 9 months(brim to brim method every week). One thing I've noticed is that tyre pressures are very important. Did a 200mile round trip at the weekend. On the first 100miles I was running unladen tyre pressures & managed 50mpg(according to the trip computer), however on the return journey I pumped the tyres up to the correct laden pressures & managed 60mpg.

This is probably why you can achieve high mpg then as constant speed motorway driving is pretty efficient on fuel. Still, who wants to drive for economy anyway?

Guilty as charged I am afraid, flashed you the other week at the BP just past Invergowrie.

Will keep an eye out for you mate.

The Trip computer actually measures a different average mpg than the "brimming method"; which is why it gives different results.

The mpg it gives you is fuel economy averaged across time, whereas the "brimming method" gives you fuel economy averaged across fuel usage.

So if (totally imaginary figures) you do 30 mpg at 60 mph and 60 mpg at 30 mph, and drive at 60 for half an hour, and then 30 for half an hour. The trip computer will read that you've averaged 45 mpg, but measuring miles covered divided by fuel used will give you 36 mpg - quite the difference.

Um... Never even seen you. Probably still half asleep

What really hacks me off is that I fill up, and the computer gives me range of c540 miles. This drops off quicker than the mileage goes up till I fill up having done c440 miles with maybe a range of 10 miles left.

Fill up. Range 540 miles....... So it goes on!

so realistically speaking, you get approx 380 miles in a full tank with normal/spirited driving?
