From experience how good/close are book figures to what you actually get MPG wise?
Looking for a daily, and now considering petrols, a lot say around 45-50mpg extra urban, but can these figures actually be done in the real world not sat at 50mph

I have always got within 2-3 mpg (when driving steady and obeying the speed limit) of the average consumption of any car ive owned. Thats with my usuall quick blat, and alot fo steady town/30/40 limit roads on the 20 miles to work and back.

All my cars were petrol engined (turbo and N/A) btw.
I think diesels are worse for quoted mpg than petrol.

That's poor! With faulty lambda and suspected duff thermostat I was getting close to 30mpg in a 323I that I used to push a lot due to the 328 exhaust it had!
With current BMW I have it's bang on to be honest. Of course depends on weather as well as it takes longer to get up to temp.
For 530D figures are:
Fuel consumption (urban) 23.9 mpg
Fuel consumption (extra urban) 44.8 mpg
Fuel consumption (combined) 34 mpg
Urban I get about 30-33
Extra urban most I had was 48mpg, but was sat at 60mph most of way, 44.8 is sat at 70-80 all the time!

I very much doubt you will get those figures from those cars, unless you will be driving along a motorway all day.

struggle to be honest
Book says combined cycle of 63mpg
Best I have had is around 57mpg for a tank but that was mostly motorways
I average 55mpg
Did achieve this once over a 400 mile round trip

parkers reckons mine can manage 50mpg i have seen that once when following people who refuse to go above 40 on my journey to work, most of the time the tank will average 42.

i'd ignore computers on cars and work out your real fuel consumption yourself
its like downloading something and its says 9mins to go, then 3mins later it will say 10mins to go

I would agree with that - some cars however are more accurate than others

Some interesting results. It seems the figures of anything made in the last 2/3 years can be ignored and taken as impossible to acheive.
Also if you look at some of the figures with/without stop start, they're a joke - eg
Astra J hatchback;
1.7 CDTi 110ps ecoFLEX 62.8 mpg
1.7 CDTi ecoFLEX 110ps (start/stop) 76.3 mpg
You what?!?

Clio got a max of 55 with a quoted 65mpg. Might do more now the injectors are new clean jobbies.
Dunno about corsa's, I know the 1.6 gets about 25mpg with nothing but hard driving. I think its Supposed to do more than that.
