6L/100Km

Is that any good for a long(ish) motorway trip? Petrol engine.

TIA

47.08 mpg

Looks excellent to me, but it depends on the car and your expectations I suppose.

Little Kia Picanto 1L. Thanks Melodeon!

I take it the quoted figures are always fibs?

Extra Urban
3,7 lt/100km
76 MPG (UK) - 64 MPG (US)

Or would you have to be doing an exact speed, downhill with the wind behind you?

bazz26 · 27-05-2018 12:20PM

Small cars with small engines are not designed for motorway driving. Your doing well getting those figures imo considering a 1.0 litre engine will be working hard keeping a steady pace at motorway speed which it was never designed for.

As for the official figures, those figures are done in test conditions which doesn't include motorway driving which is not what a small little car designed mostly for city driving, would be measured against anyway.

I drive an automatic petrol crossover and get 8 l/100km on motorway, and 9.5 round town. A diesel would get 6 l/100 km on motorway.

Automatics tend to use more fuel (generally) and petrol uses more fuel but is not pushing out obnoxious gases and micro particles into the atmosphere.

Heavy right foot tends to use more fuel. Heavy vehicles use more fuel.

Depends on your motorway speed as well. Going at 110 makes a huge difference to economy. I can squeeze 4.7 out of my fabia but with mimimal motorway and keeping it under 110.

5.7 tends to average if I put the hammer down.

Samuel T. Cogley · 27-05-2018 12:25PM

Manual says not to take it above 3000RPM for the first 1000Km and I was quite surprised that, that's 100KMH (on GPS) so just set the cruise control and watched everything except lorries sail past :pac:

Sexual Chocolate · 27-05-2018 12:29PM

That's not bad if it's true. My 1.8 civic does about 5.7l/100km that's keeping it about 115kmh

Manufacturers figures are unachievable in real life - they test the cars at high altitude, disconnect the alternator, tape over the door, bonnet, and boot panel gaps, strip out stuff like mats, spare wheel, rear seat etc. overinflate the tyres, user thinner than normal oil, and lots of other tricks.

ofcork · 27-05-2018 12:47PM

Werent they supposed to be doing real world figures now its false advertising really,the lowest ive seen in my 2l diesel is 4.7 on a long trip on N roads usually stays around 7.3 mostly urban.

bazz26 · 27-05-2018 12:48PM

Those new tests are only coming in now, it's possible that the OP bought a car that was in stock before the new testing became mandatory.

I get 7.5/8 out of my dsg gti on a long run :cool:

And they remove the wipers, wiper motor, the water bottle, air con units..

I thought that they used rolling roads to simulate "real world conditions" , which is why VW got away with their less blatant cheating for so long.

_Kaiser_ · 27-05-2018 07:14PM

On my mostly motorway spin (an hour each way daily) I get around 6.8-7.4 l/100 .... but that's in a 3L TDI Quattro automatic that hovers around 2000 rpm @ 120ish km/h

Pottering around town however, is not good!

Alun · 27-05-2018 07:53PM

I have a 1.2 petrol Nissan Pulsar which gets around 6.4l/100km on a long motorway run if I stick to the limit, more like 6.8 if I don't. At 120km/h indicated it's at just under 2500rpm in 6th gear so not even remotely "working hard".

Whether it is good or not depends on the speed you were doing and the smoothness of your driving. If it was smooth at 120, I'd be very happy with it. If it was at avg 90-100, not so much.

Water John · 27-05-2018 08:17PM

I have a Mazda 1.6D and it dips under 6.

0lddog · 27-05-2018 08:34PM

OP, is she new ?

If so, you might get more from her when shes loosened up, so to speak.

FWIW her air resistance @120kph would be around twice what it is @90kph ( but wouldnt expect rolling resistance to change with speed )

Total resistance = rolling resistance + air resistance.

Good luck with her

100 held by cruise control at 3000RPM.

Ah that's good to hear! Yes she's new and thanks for the luck

Re resistance - an excuse for me to keep it shiny

As an aside how do you tax a new car? Do you wait of the logbook? What if I'm stopped by the guards?

vectra · 27-05-2018 08:47PM

The new petrols are not bad at all.
My sons 1.0 Turbo petrol Focus ST line can return 53.5mpg on his work run.

I'd like to see it in the mid 50s MPG, at that steady apeed. One thing I'd check is the tyre pressures (when cold). I think modern cars are under inflated in the interests of 'comfort'. It can make a huge difference to l/100.

Oh, and best of luck with the new motor.

bazz26 · 27-05-2018 09:57PM

I'm currently getting about 7.4 l/100km from a 3.0 litre diesel, very little town driving.

TheDriver · 27-05-2018 10:05PM

I get about 4.6 L/100km out of my diesel

Greybottle · 27-05-2018 11:29PM

2006 Lexus RX 400h

Can get 7.9 if I keep it at 105-110 kmh, but mostly get 10.4-11.0 as I keep it at 130-160 kmh. Yes. I know its illegal.

Get 9.8 around Dublin, though I rarely drive in the city.

You can use www.fuelly.com to compare your mpg

_Brian · 28-05-2018 08:53AM

I’ve an ‘09 Tiguan 20.tdi 140bhp 4motion.

Long term consumption over maybe 15k kms is 7.2l per 100k

I do about 35k km’s a year.

I tow trailers regular weekly, sometimes light single axle but sometimes a cattle trailer, also tow caravan.

With the large caravan (1400kg) over a 2k km holiday it averages 10.5l per 100km.

Happy enough, don’t think I could get a vehicle to do what I need and provide much better mpg.

All the talk I see if extra tax on diesels and eliminating diesels scares the crap out of me.

20L/100km last time I checked!!:eek::eek:
