Aygo Economy

[deltadam]

Hi folks,

I have a brand new Aygo, the most basic u can buy, wind up windows, no central locking, no a/c, no floor mats - I was determined not to get suckered into that 'for a few pounds more you can have this or this...' I wanted to keep costs down to a minimum - especially aware I could have got a C1 with all the extras far cheaper - but call me mad - I wanted the Aygo. And guess what. I absolutely love it. Its like going back in time having to wind my windows down, crikey, I havent done that since my mark 2 Ford escort!! And lifting up the door locks to let someone in. I know it's crazy but there is something nostalgic about it...

It's responsive, nippy round town, agile, easy to park, surprisingly roomy (I am 5ft 11") and yes a tiny boot but you will get the week's groceries in (perhaps some on the back seat as well)

OK, so it takes a bit of time to wind up to speed on the dual carriageway, but once there - about 35mph (only kidding) it feels stable and true.

All in all I am over the said moon.

But. There is a But.

As I have never owned a brand new vehicle before, could someone please advise - does a brand new engine need to 'wear in' or 'run in' before it will produce it's maximum fuel efficiency? The reason I ask is one of the main attractions to the Aygo was the superb fuel economy offered - and to coincide with my purchase, I uploaded a 'FuelLog' app on my phone, looking forward to be wowed by the results of it's efficiency. I have only filled up twice so far - but concede to being slightly disappointed at results thus far: Average Fuel consumption - 53.64mph. Worst: 51.87mpg. Best: 55.41mpg. Now while I admit its pretty good, do the official figures not claim the slightly more optimistic figures suggesting over 61mpg? Maybe its the app that is inaccurate, or maybe I am just expecting to much to soon. I have certainly been driving very sensibly, indeed I haven't dared over rev my new little 3 cylinders... Any comments or advice would be appreciated.

Now I must go, I cannot remember if I locked my Aygo or not, I must go outside into the rain and make sure all the door knobs are down...

I have done 10,000 now and have tracked every tank of fuel. The worst was 50.4 mpg, the best was 59 MPG, its usually at 55mpg, thats motorways at about 70 ish on a 70 mile round trip.

Toyota said that there is no running in period, though I did not take it above 50 MPH for 500 miles

[Jan&tone]

Your fuel consumption is pretty average for a new engine.

No running in as such is needed, just common sense, don't thrash it for the first 600 miles and don't keep the speed constant for more than 5 minutes is mentioned in the handbook somewhere I believe.

Enjoy the car, the Aygo is cheap, cheerful, funky and a great drive for a small car!

Hi

Your fuel consumption figures are pretty much like mine after 30,000 miles of driving. If I really go easy, stick to motorways only and don't go much above 60mph I can get 60mpg at times but it becomes a real pain. Remember the other benefits of Aygo ownership as well as the fuel economy = very cheap car tax, insurance, servicing, tyres etc

[deltadam]

Not over 50 mph for 500 miles? Wow that's impressive! I have just about managed not to go over 65, but even that has been tough!!

I guess I shouldn't complain at about 55mpg - its pretty good really!

Thanks for your reply :D

I will indeed enjoy the car - Thanks for your reply!

Absolutely - exactly why I bought the thing! Generally really pleased with it! Thanks for the reply :D

I've tracked my fuel and milage from buying my aygo from new and i found that after the first 1000 miles my fuel economy increased from about 52MPG to 58MPG, but that may have just been me getting used to it as well. Now after 15000 miles the average fuel economy is 58.8MPG, with the highest being 64MPG.

Also remember in winter fuel economy goes down due to colder weather and headlights/wipers/demisters being on.

Points taken. I will continue to monitor with interest. I will continue to post results. Thanks for your reply :)

I don't think you need to worry about running in new Toyotas too much these days - I drive them pretty much as normal but avoid thrashing them. Avoid letting the engine labour is going to be as important as not over-revving them. Taking things steady at first will also be sensible for the tyres, brakes etc. I think Toyota engines have quite tight tolerances and so you will probably find they loosen up after a few thousand miles.

I am still impressed by mine - the first 900 miles have been good!

Never go by the official fuel economy figures - you will always struggle to match them with any car. Getting close to the official figures should be seen as a bonus. I'm very happy when I achieve 60mpg, which seems to be getting more and more regular, oddly! The worst I've had is something like 51mpg. The app I use to measure my economy is called Road Trip - very good indeed.

[MartyB]

My economy picked up after a few thousand miles and the engine also feels nippier. The C1 I had before did the same. I mostly do country lanes to work with few stops or traffic and average 60PMG, works out at 10p a mile. Lot depends if you thrash the engine. If your keeping up with traffic then you are probably driving it to hard and wont get the good economy.

Paying more for the Toyota Badge is madness. I used the cost of the C1 to haggle the price down on the Aygo. My first car was the basic one but it kinda drove me mad not having remote central locking so the nostalga soon wears off. Plus I found the C1 service department a lot better.

Yes I agree, I will aim therefore for 60mpg. Here's to trying! will post up next figures on next fill up. Yes these apps are superb, wouldn't be without one now! Thanks for reply :)

Yes I can see the 'nostalgia' novelty soon wearing off. Oh well. Toyota service department experience obviously yet to find out. We shall see... Thanks for your reply :)

[l33nces AYGO]

I always think if u can get within 5-8mpg of the official figures on true day to day driving ur doin well. I use mine as a commuter down the m40. I normally have to bomb it to work (bout 80ish) as I'm normally running late then cruise Home at bout 60. I'm getting bout 51mpg which I'm well chuffed with, I know if i drive very sensible I can get 55mpg no problem.

[dwilson]

I find the combined mpg official figures a good guide. My mpg has always been just under the combined mpg for a wide variety of cars.

[S_J_P]

Interestingly I've found that my consumption is very seasonal, with April/May consumption being significantly better than December/January on two different Aygo's over the last two years!

[Cyker]

Yeah, that is physics at work :)

Warmer temps = lower air density = less can be burned per cycle

You may also notice that in winter, the engine feels more powerful! This is because colder temps = higher air density = more fuel burned per cycle! :)

I've had my Aygo 06 Sport for 8 weeks and have been calculating fuel efficiency at each petrol stop.

I have recorded this on 5 petrol fill ups and I am not impressed with the fuel economy. As this was a key factor in "downsizing" to the Aygo I am somewhat frustrated at this, particularly when reading claimed MPGs on this forum.

I have to point out that 80% of our driving is high consumption ie cold start, short urban cycles. We drive according to best practice concerning acceleration, braking, tyre pressures, gear changes, electrics, aircon (never used) and so on. We are doing everything reasonable to drive for economy!! In fact we quite like the challenge of it- makes you realise how inefficient our driving used to be !

But.....the fuel consumption on each fill up has been 37.2, 39.2, 42.9 and 40.4. At around 300 miles on the trip we get the flashing fuel light. In addition, we drove one 318 mile motorway trip at NO MORE than 65mph and achieved 50.4 MPG. Hardly impressive?

My expectations are not unrealistic are they? I would be happy with say 45-47 mpg average for urban driving and 55 mpg for a motorway trip. That would trim £250 from our annual fuel bill.

Unless posters on this forum are telling porkies (why?)or can't master basic primary school maths, my fuel consumption appears far too high for an Aygo !!!!

My question is this. Is there a diagnostic test a Toyota dealer can carry out to determine why our car is running below optimum fuel efficiency?

ps The car itself is excellent....love to drive it!

If you are really driving economically with correct tyre pressures etc.

I am sure you should be using less fuel.

As an aside, I run 34psi front, 32psi rear all year round to even tyre wear out.

(I found the front shoulders were wearing more than the centre on the front tyres).

I have recently come back from a Europe trip with a fully loaded Aygo.

It was showing about 65mph on the motorway. Lights, wipers & heater on all the way, 59mpg.

My wife driving to work at this time of year, 6 miles there, 6 miles back from cold, will still average 52mpg.

I did notice on my 4 year old Aygo, when it had its 4 year service including plugs & air filter,

my fuel consumption went down. Not dramatically, but before it went in, I checked the plugs & filter

and they didn't seem dirty / worn.

Perhaps, your car IS in need of a service / checkup.

My only other suggestion......After driving an IQ with a change up / change down indicator,

I changed up when it suggested at what I considered too low revs.

It pulled higher gears without labouring.

If you are used to a larger car, you may be revving the engine too much.

I use a very light throttle most of the time and change up early.

The IQ was suggesting changing UP while on the flat at (sometimes) 1500rpm!

It is, as you say, the worst time of year for fuel consumption.

I'm sure you will achieve much better figures in summer.

Ian.

Just to say that my fuel figures are posted on Fuelly and are genuine. I don't need to use any maths as the website calculates it for me but as a physicist my maths is ok!

I try to avoid hard accelerations uphill but otherwise drive it quite briskly. I look well ahead and don't leave braking to the last minute but when I can get the power down (well what there is in an Aygo) I go for it! Other traffic slows me down rather than the car. Waiting for the car to warm up on icy mornings means the mpg take a bit of a hit at this time of year but I expect to make up for that in the summer months.

As others have queried - does your car need servicing? Do you get caught in many traffic jams ?

[Bravo533]

Our car was bought from a Toyota dealer - it was last serviced by them in June 2011 - only 2300 miles ago.

Hence my question about some sort of malfunction on the ECU/ECM which only the Toyota service dept diagnostic gizzmos can detect?

Are there any Toyota technicians out there?

BTW the car has only done 19000 since new in 2006 - one owner.

Sounds good - I suppose the exhaust is ok?

How do your mpg compare with previous cars over same routes?

Our previous car on the same routes was a 1.2 8v Fiat Punto 54 plate with 75K miles. It averaged 37 mpg (before we adopted fuel saving driving methods used with the Aygo) and once returned 58 mpg on a return trip from York to Oxford.

Hence my disappointment with our Aygo economy.

[grinner82]

I drive at 70 MPH on motorways mostly and get 54 MPG most times, never worse than 50 never better than 59.
