Sorry. Another Boring MPG thread.

Whats the best MPG that can be had from a petrol engine. I'm wondering how much I could save switching to a fuel efficient car but I don't want a diesel. My clio cup gets an easy 40mpg if im fairly carefull. Now thats very good for the PH factor of the car, So i'm not going to go out and buy a 1.2 if it will only get me an extra 5mpg.

So I'd have to be looking at a petrol engined car that achieves and average of 50 mpg. Do these exist? I'm not sure they do. I know I can get a diesel that easily does that but I dont do mega miles and everyone i now with diesels get high service costs.

Any ideas.

Really? 65-70mpg on the motorway. At what speed? What car and engine is it. out of the 3 I mean.

Thats cheap motoring.

I'm in a similar situation. My MR2 gets a consistent 40mpg and so I'd have to have a car returning 55-60mpg for me to even consider changing.

I tried an IQ for 24 hours and it's a cracking car (shame on me!). Once you get used to the short but wide wheelbase it's surprisingly good to drive and doesn't feel like a 1.0 litre spud box.

The only trouble with it was that it was only showing 43mpg on the computer although it was the rep's car so reckon it was thrashed everywhere. I think I could do much better but sadly the computer only reset itself once you filled it right up and I wasn't prepared to do that.

I realise a small turbodiesel would be more usable but I seriously liked the IQ after a day with it.

I traded in my Renault Sport Twingo 133 for a Clio 1.2 Dynamique to save fuel... Economy didn't really change between the two. Now driving a diesel and noticing a MASSIVE difference in economy even though I don't cover many miles.

underneath the C1/Aygo/107 are the same car, all using the Toyota 1ltr 3 cylinder lump. The misses 107 does mid 50's ish around town and 65 ish on the motorway, £20pa road tax to boot.

My CRZ is averaging 51.6mpg over 3500 miles, mostly around town. On motorway journeys I get 55+ mpg.

20 QUID! Im sure mines around £260. Its the tyres that I cant stomach replacing. Nearly £90 each. I presume they're utterly miserable to drive??

avg of 69.5 mpg for the day.

We have a C1 for a run-around. As above, tax has come down to £20, easy 60mpg, cheap, cheap parts and not utterly miserable to drive. Get that little engine revving hard and can even be a laugh. Just bear in mind what it is - you won't out-perform anything on the road, but you will save bucket loads of money.

I keep wondering if I should chop in the jeep for something more economical, - it does about 20mpg on average, has been 100% reliable over the last couple of years and is nice and comfy for long journeys.

but a bit of fag packet maths suggests that even if i get something that does 50mpg, I'm only going to save 2.5k a year in petrol costs, so assuming my jeep is worth 3.5k and I buy something for 10k its going to take nearly 4 years to save the outlay back

So on balance I think I'll end up keeping the jeep, as it doesnt make financial sense to be economical

£90 for an RS tyre? That's nowt really, for low profile sports tyres for 18" wheels (ala Seat Leon Cupra R, Astra VXR etc) you are looking at £160 and up per corner!

Was just going to suggest that. My Brabus Smart Roadster Coupe (the one with the greenhouse on the back) was quite sleek and had a 0.7 litre engine. Despite it keeping up with much bigger children on all roads, I averaged 50mpg but this was without driving with MPG in mind at all.

On the m-way, I could get 65mpg at 65mph but that was boring. 80mph would see mid 50 mpg. Fun times!

The Prius is always North of 55mpg, and last tank was 63mpg, FWIW.
