MPG...

ste_bla · 10 Apr 2009 at 19:58

Just wondering, or rather a disagreement. A few of us are going away and so theres a choice of cars. Which of the following should/would cost the least (mpg wise) if travelling mainly motorways around 70-85 mph

1) 1.0 Corsa '98ish
2) 1.3 Escort '96
3) 2.0 Omega '96
4) 2.5 Omega v6 '98
5) 1.8 Mondeo '96 (iirc)

Obv me and one other (mondeo guy) want to go in either of ours are much more room but as we will be sharing petrol the oter 2 are bitchin theirs will use way less. So any ideas on roughly which would be best or even figures for them...

Cheers

Corsa, but it will be painful. It is obvious isn't it? It is the smaller and lightest car and has the smallest capacity engine. It is bound to return a better MPG.

I'd say either the 2.0 omega or 1.8 mondeo myself. If very heavily loaded or towing the 2.5 omega may be better

Well thats what one guy said but I would have thought flogging a 1.0 would use more petrol than a gentle (revving) 1.8 or 2.0

clearly it's not for you!

I agree with The Edge, you will find you just end up working the smaller engines that much harder, they will be revving higher all the time, thus your fuel economy will be shot to pieces.

Just tell them if they are going to bitch about petrol costs they can drive their own cars then. I'd just stick with yours.

I'd guess at the crappy Corsa having the best MPG, but I don't actually know.

lordrobs · 10 Apr 2009 at 20:05

I'd say 1.8 Mondeo would be best followed by either the 1.3 Escrote or 2.0 Omega, don't think their would be too much between those two.

Firestar_3x · 10 Apr 2009 at 20:07

I'd say the mondeo but it depends on how the omegas are geared.

the suck

2.0 is 2500rpm @ 60iirc
Last year I got (doing 70/80) 36mpg being gentle with the gas

2.5 is nearly the same MPG (1 or so less), I just dont know what the other cars are like..

I'll say to the guy with mondeo we can go together (in his or mine) and the other 2 can have fun together or not..

Why? Am I wrong? Would the Corsa return a worse MPG?

Moeks · 10 Apr 2009 at 20:12

If it's one of those old 1.3 OHV engines that first appeared in the 1970s Fiesta MK1, in the escort, then it won't be especially economical, they are totally gutless, hideously unrefined pieces of pig-iron, basically. Does it even have a 5 speed gear box?

it has a chain (not cambelt) and 5 gear speed box other than that :confused:

At 70 possibly not but at 85 probably.

My 1.8 Octavia gets better fuel economy over an 80mph run than our 1.4 Polo. Day to day though the Polo averages 41mpg whilst I only return just over 32mpg.

Problem with small engine on the motorway is the engine will be doing more revs than a larger engine thus bad fuel economy.

SpeedFreak · 10 Apr 2009 at 20:18

I used to borrow my mates 1.0 Polo for a while and on runs on the M5 the MPG was shocking at an indicated 85, which was probably 75-80 mph. I would say the 1.8 Mondeo and to be honest, even if the Corsa was better, it will be marginal with 5 guys and there is no way in hell I would sit with two other blokes in the back of a Corsa for any real period of time.

How far is the journey?

Janesy B · 10 Apr 2009 at 20:19

Yes it does have a 5 speed and yes it is a Kent OHV engine which actually appeared in 1959 with the inlet and exhaust on the same side, then there was the crossflow but with the exhaust and inlet on opposite sides then for adapted it for the mk1 Fiesta and called it a valencia. The one in the Escort would be a hcs or endura-e engine which is the same as the valencia but with a few revisions.

My 1.3 Escort would chew through a full tank in about 280/300 miles. It was pretty awful.

A tank lasts me the same distance on my Fiesta but the tank in the Fiesta is about 13 litres smaller!

I think it just depends on the car/engine.

Around town it would be better, but at quicker speeds it will be working a lot harder than a larger engine, so would give poorer MPG overall. Don't forget the added weight of passengers, luggage, etc - it will struggle.

Sod which is cheapest - go with the most comfortable.

So that'd be the Omega or the Mondeo.

Peter Diffey · 10 Apr 2009 at 20:43

Either the Corsa or the Mondeo, dependant on speed. At a higher speed the Mondeo will be more economical because it should be a lower revs.

Saying that, I used to easily achive 45MPG when driving 80-90 indicated over a distance of about 200 miles in my 1.2 Clio.
