Fuel Consumption

[Not Happy]

I have just joined the yaris club & haven't as yet
read any topics but I was wondering if anyone has a 2014 yaris hybrid that has
the same extremely poor fuel consumption as mine of 43.8mpg. I use the car very
carefully & don't over accelerate heavily, I also use the eco mode &
that's the best mpg the car can achieve. Shocking for a hybrid I would say.

What are you comparing the consumption to - is it the official EU consumptions figures? The EU testing regime is laboratory based and bears little relation to what owners can usually expect in real life. See http://www.toyotaownersclub.com/forums/topic/155252-eu-fuel-consumption-tests/

A better indication of what owners are actually achieving is the information at Honest John Real MPG - see: http://www.honestjohn.co.uk/realmpg/toyota/yaris-and-yaris-hybrid-2011/15-vvt-i-hybrid

How are you measuring the consumption - are you going by the consumption figures on the car's computer or are you actually working out the consumption using more accurate brim-to-brim calculations?

How many miles has the car done? It won't begin to deliver its best consumption until it has done at least 4000 miles, possibly more.

Other topics on the Yaris Hybrid's fuel consumption are here:

Thanks for the info & your saying exactly the same as the dealer said. However, everywhere I have now looked, anyone remarking on the yaris hybrid mpg, are coming up with similar figures. My wife knows a couple who own a yaris hybrid & have had it a year & the mpg figures aren't any better. I haven't done a brim to brim calculation but the fuel gauge seems to back up what the computer is registering. I will be trying a brim to brim calculation on my next refuel. My thoughts are, that it's a bit of a, (robbing Peter to pay Paul) scenario. When you're driving in the built up areas, the electric motor powers the car frequently, however, the petrol engine has to kick in to recharge the traction Battery cells so no real saving at all. This is made worse because the extra weight the car is carrying by way of Battery & electric motor means the petrol engine has to work even harder. I'm almost willing to bet that if the car only had the petrol engine, the fuel consumption would be nearly double of
what I'm getting now.

One other thing that can affect the fuel consumption figures displayed in the car, is filling up with less than 15 litres of petrol. Topping up in relatively small amounts can result in inaccurate fuel consumption being displayed - this affects a number of Toyota models (eg the Auris, Yaris, Aygo, IQ) and not just hybrids. So ensure that when you fill up, you put at least 15 litres in.

I usually have to put more than 15 litres in when I refuel it but thanks again for that info.

"I'm almost willing to bet that if the car only had the petrol engine, the fuel consumption would be nearly double of what I'm getting now."

You would probably get between 48-60 mpg out of the 1.0 litre, 40-51 out of the 1.33 and 39-52 out of the 1.33 CVT, and certainly these would also need a few thousand miles under their belts before getting the best consumption.

June 2014 What Car reckon on real MPG on a Yaris hybrid of 47.7mpg.. (vs EU 76.3)

(I did not buy a Yaris hybrid as it was obvious the figures were impossible in real life..)

[Cyker]

That's pretty bad I thought most of the HSD Yaris people here were at least getting mid-50's with a few getting better mpg's than my D4D! Why're people getting such bad mpgs now?!

[Madasafish]

A lot is technique

And hilly country is a hybrid's worst enemy: after the Battery is c80% recharged, no more regeneration.. So you expend a lot of energy on the way up and recover a little going down...

(It's very hilly here : we live 1/3rd of the way up a BIG hill).

And if you drive short distances and the engine never warms up, you will never achieve the urban mpg - which in EU tests is with a hot engine. And a hybrid is best in urban conditions..- but only with a hot engine.

So use for two mile runs? Forget EU figures.

My Jazz has an instant mpg indicator. Averaged c 40mpg around town: BUT when cold, it averages sub 30mpg before it warms up. Simple thermodynamics.Add in people who aceclerate when cold.....

[Not Happy]

I've tried all the recommended driving techniques given by the dealer & the manual & where I live it's pretty flat with very few hills but let's face it, the reason for buying a hybrid is for fuel economy
& the yaris hybrid doesn't really do that (or at least mine doesn't). I would have been nearly better off buying a 2 litre twin turbo diesel Jag.

[Cyker]

I imagine it'll get better once the engine loosens up; Problem with HSDs is that can take a lot longer than a petrol or diesel car as the engine gets so little use, and even then only for relatively short periods of time.

Maybe take it on some long trips on some fun A-roads? :D

Take it on a good thrash now and then instead of driving carefully all the time, that'll loosen it up

But seriously, I find babying a car too much can actually be worse for it. More so for us diesel drivers for sure, but even with the HSD it's better to just get on and drive it instead of worrying so much about mpg all the time.

It'll come round eventually!

(Most of the Prius drivers I've encountered recently certainly seem to be doing that! There seems to have been a sharp increase of angry high-speed Prius drivers on the motorway lately! )

Take it out of eco mode and see if that helps

I have had my Yaris Hybrid for 6 weeks now and am coming up to 2k miles (I cant stop driving it)!

I am currently averaging 62.5mpg as shown by the OBC. My best so far is 66.5mpg.

It has been in ECO mode once, and I hated the drive in ECO. Kick it out of ECO and just let it do its stuff. I can now tell when I should be in EV mode and a slight readjustment of my right foot and bingo, it slips into EV mode.

You have to be as one with your Yaris to understand it fully.

[martswain]

Got to agree, just leave it in D and let the system sort itself out.

Make sure you DO use some revs occasionally to condition the bores,

[Not Happy]

NCFCbuff, if you're getting 62-66 mpg, I would get it in the Guinness book of records as these are excellent figures. If you look at all the other forums & reviews, the best I've seen is 52mpg. Toyota should supply a tow hitch & specialised bowser to carry extra fuel for mine. I do realise that as the engine & electric motor loosen up the figures for mpg should rise (I hope), but I don't think mine will achieve anywhere near 62-66mpg. Not when it's only getting 43.8 at the moment. I will try taking off Eco mode to see what the difference is but a car should do exactly what it says on the tin without any special treatment & the yaris hybrid doesn't. Thanks every one for the replies.

Had my 2014 Yaris Hybrid for 2 mths now and over the last 400 miles I've averaged 65mpg. Even managed 79mpg on a 5 mile round trip.

It's been a very sharp learning curve to achieve this and I've had to completely change my driving style. My round trip commute to work is 40 miles with a mix between single and dual carriageway. The traffic varies from very heavy stop and start to free running. I let the car coast as much as possible and when accelerating I try to keep the car out of the power part of the counter. I also use cruise control as much as possible, even at 30mph as it's a lot smoother than I am on the accelerator. I also keep the car in Eco mode.

When I first got the at it had 10 miles on the clock and I was getting 54 mpg, I've now got just over 2000 miles.

Hi i think what the others say is right, you have to do 4000 miles before you start getting a reasonable mpg with your yaris mine is a 2012 hsd with 1200 miles done and i am getting 68 mpg around town and up to 73mpg on long trips let us know how you get on

[IanLorenc]

I've had my Yaris Hybrid for about eight months, covered about 4500 miles, and averaged 60.1mpg over that time:
http://www.fuelly.com/driver/ianlorenc/yaris-hybrid

The best I've seen on the trip computer, for one small trip (about 5.5 miles) was 73.2mpg.
I started using the instant mpg readout recently, and I discovered that the car is very uneconomical when the petrol engine is running, and helping to charge the batteries. In these circumstances, cruising between 30 and 55mph, returns an instant readout of between 40-50mpg.
However, once the batteries are full, cruising at those same speeds returns an instant mpg of between 60-99.9+mpg.
I was 120 miles or so into my current tank of fuel, averaging 62.9mpg, when I decided to try using the petrol engine as much as possible, saving the batteries for slow speed manoeuvres and any jams I encountered (I'm also trying to get better at pulse and gliding, and what I call "stealth-glides" - no arrows showing on HSD screen).
Straight away, the average started to come up.

As of writing this, the trip computer says I'm averaging 66.8mpg, and that's over 291 miles.

I don't know what kind of routes or traffic conditions that the OP encounters, but I have about a 40/60 suburban-rural roads split. Mostly quite clear, occasional jams.
Also, I've never had my car out of ECO mode.

Interestingly, in America, the Yaris Hybrid is called the Prius c (different styling and instruments, but everything else the same). My point for raising this, is that perhaps our Euro economy tests are way out, as the US EPA fuel tests rate the car at 50mpg (US), which is 60mpg, UK. Which I've found to be spot on, and achievable without resorting to hypermile driving techniques.

[FROSTYBALLS]

The Prius C is built on the same platform as the current Yaris, albeit lengthened by 40mm. The bodyshell of the Prius C is also slightly longer and lower than the Yaris. The Yaris Hybrid uses the powertrain from the Prius C.

The next generation Yaris to be sold in the US (2015), will be based on the forthcoming new Mazda 2, and will be built by Mazda for Toyota at the Mazda plant in Mexico.

[IanLorenc]

I wasn't aware of those dimensional differences between the Prius c and Yaris Hybrid, thanks for the info.

As far as the figures being mentioned regarding the mpg, these are incredible averages compared to what I'm getting. I would have to fit peddles to mine to get anywhere near the 60 - 70 mpg. I've tried everything else from driving it like it was made of candy floss & in Eco mode & driving it normally with the Eco mode off (like a real car). I don't think you should have to drive a hybrid car any differently to a normal car anyway. It should be fit for purpose & what it was designed to do as a hybrid (be economical).

[IanLorenc]

Just out of interest, how long in miles, is your commute?
I've looked back over the thread and can't see it mentioned.

Also, what was your previous car, and what did that get to the gallon, over the same route?

It definitely sounds as if you'd be achieving similar MPG figures from a 1.4 petrol only engine. I certainly wouldn't be happy with this situation either.

I wonder if this 'MPG-anxiety' is why I'm coming across so many people really dawdling along the road - almost as if they're afraid to use the accelerator ? Doing 35-40 mph in 60 mph zones is even holding up HGV drivers, never mind those of us in 'normal' cars ....... Nothing personal against you Alan, just an observation !

[Chrisc100]

hI i have posted my mpg to this topic, but i as unaware that you could take your car out of eco mode. i thought that all you could do was put it in eco or ev mode What do you do just press the eco mode button?

[SK100]

Hi all, I've just joined the forum and came across this thread. I bought a new Yaris Hybrid in March and have so far done 1700 miles. I thought you might be interested in my experience with fuel economy. I've definitely found that economy improves with both running in and by learning how to get the most out of the hybrid system. On my first tank of fuel I achieved 53 mpg calculated brim to brim (in-car display read 57mpg) and by my last refill I had got to 61 mpg (65 mpg on the in-car display). On my current tank, the in car display is indicating an average of 70 mpg over 250 miles. This is likely to be a real 65 mpg brim to brim. I always keep the car in Eco mode and never use EV mode. To get the best economy it is worth making some adjustments to your driving style. There are many really good tips and techniques that I've found in both the Hybrid/Prius section of this forum and on some US forums such as Priuschat. It's worth doing a quick search and adopting some of these techniques if economy is a priority. Key ones include Pulse 'N' glide (using Neutral gear for the glide bit below 40mph), brisk acceleration from stationary rather than trying to keep the car on pure electric power, and using the HSD in car display to optimise your driving for fuel economy. I also keep my tyres pumped up on the high side (36 psi all round). Overall I love the car, it's brilliant and has exceeded my expectations but to get the best economy you definitely have to adapt your driving style a little.
