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

TIA

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

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?

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.

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

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

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

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:

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.

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

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

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

0lddog

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?

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

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

TheDriver

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

Greybottle

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

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.

3000rpm at 100km/h that's revving very high. Most of my cars, which are all petrol , would be less than that at 120. Only car I've driven that revved that high is my Dad's 1.6 petrol Focus, I keep thinking I'm in 3rd gear on motorways.

To tax you use the last 6 digits of your VIN as the PIN on motor tax online. You get the VLC after you tax it.

Small petrol engines will have a high rev range. Very little torque.

.

I don't think it's high at all.
Many petrol cars would have such ratio.
My 2 litre crv would be about the same 3000rpm at 100km/h.

Petrol engine running at high revs doesn't automatically mean poor fuel economy.

When you think about it when it's 3000 rpm at 100km/h that gives you 6000rpm at 200km/h which makes perfect sense as most petrol engines would have their peak power around 6000rpm which is needed to pull the car at 200kmh.

go4it

Used a 161 1.0 Litre Skoda fabia for a year ; kinda under-powered for my taste, i could feel it's alive only from 2700+ rpm

Most of time 2 pasengers, no luggage, Dublin city centre driving at 7am and 6pm ;over 10.000km = 6.3/100km

Other thoughts: at 50km/h in 3rd gear=2900rpm ; at 50km/h in 4th gear=2000rpm ; Motorway @100km/h required 5th gear and 3200rpm ( never pushed the car more than 130km/h since i didn't owned the car and it seemed at the last power breath )

Over a few trips on motorway ( 300km ): 4.7-5l/100 km ( driven @100km/h single car occupancy )

ps: this car has NO Turbo engine , just naturally aspirated engine - chosen by the original owner for greater reliability )

No unfortunately not... Someday though.....

The only petrol engines that I've gotten close to 50mpg out of was a Toyota CH-R hybrid and a Yaris.

Recent petrol rentals......

Astra 1.4 turbo petrol 40mpg
Auris petrol 1.4 petrol 37mpg
Yaris 1.0 petrol 45mpg
Corsa 1.0  33mpg
Seat Ibiza 1.0 35/37 ish
CHR Hybrid 50mpg
Ford Edge 2.0 ecoboost 30mpg 
Renegade 1.4 multiair 38mpg ........

...... and in diesel FYI ..
Tipo 1.6 95bhp diesel 42mpg
500L 1.3 diesel 50mpg
Focus 1.5 diesel 50mpg
Kuga 2.0d 2WD 45 mpg
Fabia 1.4 tdi  55 ish mpg

I'd have had all of these for at least a week iirc, some for a month or so.

3.0TDI Quattro

7.2L/100km on a 640km round trip (wasn't taking it particularly easy either)

9.2L/100km averaged over 10,000kms

I find this economy excellent for the size of the engine and for the power that’s on tap.

Hard to beat a large Diesel for a long motorway journey!

Preach brother!

Fantastic engine and yet economical enough that I can do 1300km a week in it without crying too much over the bill at the end of the month

Little 80km spin in the 1.0 TSI dsg Octavia today 5.2/100km. 2000 rpm @ 100 km/h.

Chevy Silverado 6.0 petrol crewcab.
15mpg average. 7mpg when towing a 31 ft trailer.

Don't ask me about l/100km nonsense!

My wife's 12 year old Octavia with 300k Kms on it beats that!
She regularly gets 4.9 on her M50 commute.

Here’s an interesting one!

I covered just over 2,000kms in a Camaro SS 6.2 V8 and somehow managed 12,5L/100km

Had it in ‘Sport’ mode the whole time too..



I did some maths at the time and the total cost of fuel used worked out cheaper than what it would have cost me to cover that same distance in my Audi A4 1.9TDI in Ireland.

What a painful realisation that was

At an average speed of 53 km/h try pressing the accelerator for the next 2000km and she what she'll do.

Accelerator was firmly planted on plenty of occasions I can assure you

That average speed of 53km/h also takes into account the 0km/h when sitting in traffic ... again , a testament to the relatively good consumption achieved.

is that a saloon or suv? I have a 30d xdrive in a saloon and agree with you regarding the power on tap and motorway journeys but getting a little better figures.

8.3 L/100km over past 20k kms doing mixed motorway / city commuting.
Good long journey on mostly motorway would be around 6.8 again not taking it easy

Mine is a saloon (A4 B8)

Your figures are excellent for a 30d xDrive! I presume it's a newer generation engine than the 3.0TDI hence the better fuel economy

What model is it exactly?

Yeah latest gen 5 series g30 530d, had a 520 before hand and the engine is so much nicer than the 4 pot.
