Cupra mpg???

[Jamesemt]

My Ibiza Cupra doesn't seem to achieve more than 38mpg on back roads taking it steady...ie not going over 60mph, not revving it over about 2,500rpm.

What would yours do under similar circumstances? It's remapped BTW.

I'm getting about 46mpg down the motorway at 80mph??

Car only has 4,000 miles on the clock, which I reckon is part of the problem - but its not going to make THAT much difference, is it? 3,500 of those miles are remapped too.

By means of a comparison, the wife's vRS struggles to drop under 50mpg whatever we do with it...

As a little side note, the vRS was thrashed senseless from day one - I managed 120mph with 7 miles on the clock - and in the last 10,000 miles (its done 20K) it hasn't used a drop of oil...I've tried thrashing the Cupra to the same level but lose my bottle as I run out of road

 

[justlivyalife]

At a guess the vRS is standard?

Soo I assume that the additional power means a lot more fuel is used when you're accelerating? 46 on the mway at 80 seems pretty good - what MPG you getting @ 70??

 

[Jamesemt]

About 49mpg...I thought the idea with remapping was that if you didn't boot it, you also had more torque - meaning you saved fuel??

 

[TonyK]

I get about 40 over an average journey from my Cupra and it's just passed 3500 miles and is completely standard. On motorways I average slightly higher speeds than you and get about 38 - 41mpg - On a normal drive to work which is back roads and dual carriageway (and queuing in traffic) I get about 40ish but I have got quite a heavy right foot.

 

[Jamesemt]

Do you expect it to get any better than that?

Maybe I've been a little spoilt with the vRS...

 

[TonyK]

From what I've read it takes diesels a few thousand miles to loosen up completely, anything between 10 and 20,000. Other question, have you tried it turning the climate control off (ie press the econ button) and seen if it makes a difference?

 

[Jamesemt]

Those mpg figures are with the climate off - the mpg is even worse with it on...

 

[Diablo559]

280 t0 290 miles to the tank car just about to hit 20000 miles so hope it gets better computer says 32mpg have to drive worse than a granny on a sunday drive to get over 50 lol. and its revo'd just to let you know

 

[Sisson]

You must all drive with heavy foots...

In the last 2.8k miles the trip computer is saying an average of 52mpg...

I rarely see it go below 50mpg and easily see into the 60's...

Mines C-C'd and that 2.8k includes a fair few 3 figure blasts... on my private road.

i never get below 400 miles to a tank, its normally 450-500...

To be honest, it's pointless comparing your own fuel economy with everyone else's, because everyone's driving conditions vary such a lot.

In my experience, how heavy your right foot is makes surprisingly little difference with the TDI. What makes by far the biggest difference to mpg is congestion. On my daily commute, I typically manage about 45 mpg (remapped PD130) - but that is also with an average speed of no more than about 22 mph because of congestion.

But when I do a long motorway journey with clear traffic (doesn't happen very often!) the car can do anything from low 50's to low 60's. On the motorway, wind starts making a fairly big difference because aerodynamic drag starts to dominate at higher speeds. Even a gentle 5-knot tail wind will improve your mpg quite a bit, whereas that same wind blowing against you will degrade economy. You may not be aware of what direction the wind is blowing, particularly on a day when it doesn't seem very windy, but it can easily make 5 mpg difference between a headwind and tailwind. I've also noticed that a wet motorway surface seems to make a difference too - presumably the tyres are using some energy to displace the water, resulting in poorer mpg.

But to be honest, you really shouldn't worry about your mpg with a TDI that only has 4,000 on the clock. You should continue to subject it to a variety of power - including plenty of firm right-foot action once it's warmed up. This will help to break the engine in properly. Do not drive it too gently at this stage of its life!

 

[EdButler]

Ill echo everything David has said - Heavy right foots are actually good for diesels as theyre more energy efficient when accellerating up hills rather than maintaining speed, just so long as you use that inertia later on!

Just make sure you drive with anticipation, dont keep anchoring for coreners and traffic lights, avoid congestion at all costs (my MPG to work goes up by 12 in the school holidays!).

 

[TonyK]

I wish I could avoid congestion, I've decided that schools should be forced to have staggered start times and large bank HQ staff should have to start work before or after me (I've got 2 schools and 2 banks on the way to work).

I'm doing my best to loosen up the engine I promise! (and yes, letting it warm up first) It'll be interesting to see if things improve in a few thousand miles. Cheers for the info guys.

That's quite interesting - shall keep that in mind when I get mine in a couple of weeks!!!!

yep absolutely agree.

James - you need to get some more miles stacked on it as it will still be very tight, the milestones of 20 and 30k for TDIs and running in apply, and dont run it in my driving on low revs.

Ps, for max economy keep the engine between 2k and 3k rpm, any lower than 1500 rpm and the engine is labouring, 2k is roughly where peak torque is so this is where best mpg can be acheived.

That's a very good point too. It isn't the go-pedal that costs you fuel - it's the brakes!

I think of the brakes as being devices that convert fuel into dust - both of which you've paid for. There's nothing wrong with accelerating hard, but if you have to brake immediately then all you've done is convert that fuel into brake dust and heat.

 

[Triple D]

well you think that is bad, occasionally ( and yes ill admit it, i do drive with a heavy foot sometimes ) i get my average at about 25 mpg-32. Tonight i averaged 16 mpg and yes that did get slightly thrashed of 6 miles. But, drive it sensibly and even with the mods that i have done i can still return 50 mpg and on a couple of long runs even got as high as 64 mpg average.

 

[Diablo559]

can safety say i dont granny mine around lol not really worried what mpg it does i get my diesel free lol the joys of my dads lorry business . might explain the mpg lol. one reason i am put off a petrol car

 

[Jamesemt]

I definately don't granny my car either (it gets taken to over 4krpm every other day) - but driving away from our house is a 40 zone - the vRS achieves excellent figures, the Cupra does not.

vRS with 20k miles driven completely by me for full (vented) tank = 600 miles
Cupra with 4k miles driven completely by me for full (vented) tank = 450 miles

I suppose what I was getting at was comparable mpg between 130PDs and 160PDs.

I've mentioned before that i feel the gearing is different - when cruising the Skoda is happy with 4th gear at 30mph, the Cupra only just seems happy in 3rd. Or am I just confusing that with turbo lag? Anyone know both engines intimately? It's most noticeable when the engines are cold and I don't want to rev them - I need 2krpm showing on the Cupra to get moving, the Skoda only feels like it needs 1500rpm...

I sold my Impreza solely because of the fuel costs (it did consistent 26mpg BTW). I'm not getting the economy I expected compared to the Skoda. Although to be fair, its a lot better than the '03 Scoob which managed 280miles to a tank (which cost roughly the same as a vented Cupra tank).

 

[devonutopia]

Skoda must be a better car then.

I do find my "vRS" quite good on the fuel. I gave her a nice 120-130 thrash along the A30 (km/h) eastbound from Exeter the other morning. Still arrived at Honiton showing 44mpg for the trip. Oddly enough I covered those 14 miles in just a few minutes.
