Yep. On paper it's a smidge more economical than my Bravo but only having a five speed gearbox instead of six makes me think that in practice it won't be any better. My average from new is a genuine 56mpg but on the last couple of full tanks I've got over 60 which is very good. My Octy would typically do about 50-52 on a tank depending on how I'd driven which was still pretty impressive for a car that would also do a 9 second 0-60 (though obviously not returning 52mpg at the time) > > There are plenty of good sized petrol cars that'll beat 47mpg. At a constant speed the instananeous figure would be at that level though it would be tricker to get that as long term average. -- Alex "I laugh in the face of danger , then I hide until it goes away" I run LPG and at around half the cost of petrol or diesel per litre I reckon that I am getting high 70's low 80's equivalent � for �. Might not get as many miles per gallon but it is miles per � I am more concerned with. I average over 150 miles per �10 currently saving about �400 per 10k miles on fuel alone and �15 road tax helps too.
