Poor Yaris Hybrid Mpg?

The Yaris tank takes 30 litres of fuel.  I can generally get something approaching 400 miles on a full tank.

I just did 468miles on 35 litres in mine, although this is pretty sub par for me :unsure:

(I also just broke 80,000 miles on the odo! I'm slowly but surely climbing that Who's got the highest mileage Yaris table :tongue: )

Nice to know it should be good for 450ish. Even though the range shows 200, but i always use the trip counter for see what i get when its fill up time.

I get close to the range stated in my 2010 Auris, so eager to find out ho w the yaris compares with a smaller tank.

You will not get 450ish unless you are prepared to drive the last 50 miles with the fuel gauge showing empty and the range showing zero and carrying a can of petrol in case this is true.  The Yaris tank has a nominal capacity of 30 litres and the most I have ever got  into mine was 31.02 litres at which point the range indicator was showing 0 miles.

If I get to 400, then anymore will be a bonus. 

So I now have a good idea what to expect, instead of the silly range estimate the car is showing, 200 miles on a full tank.

I see a few people have noticed this kind of error on their cars.

Thanks for the information.

Not sure about the hybrid Yaris but this won't be any use with the gen3 Prius.

When the petrol runs out it also flattens the HV Battery and your car becomes a road block.

You have to be recovered to MrT to be rebooted.

Missing some.  36 litres for Hybrid and 38 litres for the rest from memory.

Tank is 36L, range shows 0 from when the reserve is hit, which is about the 30L mark, leaving over a gallon - so about 50-75 miles depending upon your driving style and MPG achievements.

Traction Battery only goes flat if you continue to try and drive it once out of petrol.

 

If you run out of fuel and then actually stop and refill the car from a can etc then you should be okay :)

My wife gets nervous once the fuel gauge gets lower than the half-way mark; driving with the indicator showing empty would bring more grief than my life is worth.

I am hoping for some helpful expert opinions and advice.

I recently bought a new Yaris hybrid. It's a really lovely car and I'm very pleased with it - however, the MPG doesn't seem to very good. I've done research on how to get best MPG and my wife and I are doing all the right things - driving in ECO mode, careful with braking, anticipating road conditions, getting into EV mode whenever possible, etc. I am only getting 48 - 50 MPG.

Although this seems lower than I expected, is this probably right, or should I be doing more?

Any help and advice would be greatly appreciated.

Many thanks.

I think I have interesting road conditions because I seem to get widly different numbers from most people.

I drive to work every day in a very hilly town (Yaris Hybrid 2016).

For a while, while I was waiting for my driving test, my other half would drive to my work and I would drive back. I almost always beat my other half even when she was trying to compete with my MPG.

She would do the same road (when going back home from work in the morning after dropping me off) and be about 10 MPG below me, even though when I drove back in the evening there were 2 of us in the car.

We came to the conclusion that it was because the car had warmed up.

When I started to drive on my own, my MPG went down about 5/10 miles. The car was no longer warmed up. I still managed to do 81 MPG once, now I do about 68/75.

But, on the way to work I am lucky if I do over 50 MPG.

That's because of the hills. On the way to work it's all uphill. The Battery has little chance to recharge. On the way back it's all downhill.

Anyway between motorways, travel to work and back and visiting people the average is about 59 MPG (that's through keeping track of miles and refuelling and ignoring the onboard MPG indicator).

At times I manage to get an average of over 90MPG (that's average on the trip, not the MPG I am doing at that moment in time) then you go up a hill and you lose about 15 MPG. That's because the small engine struggles, so I wager a Prius or an Auris will do better there.

My guess it is the air temperature that is difference. My journey to work is always gives lower mpg about 50, returning home I get upto 70+ (Excellent appears on my auris).

The return journey has more traffic, so that could help to skew my results.

Trouble is the gen3 just keeps going. You don't know when the petrol runs out.  The car just stops with a flat HV Battery and no fuel. :(

The gen2 does stop when it runs out of petrol (before it falttens the HV battery) so you can refil and keep going. The gen3 (1.8 drivetrain) doesn't.

Not sure what the new 1.5 drivetrain used in the Yaris does.

Can't say I follow this, you'll here it attempting to start when the traction Battery reaches critical level, just like it would if petrol was present. Its the engine constantly trying to start and turning over when no fuel is present which then flattens the traction Battery

I was always under the impression that the car would start if the Battery reached empty, provided there was fuel to run the engine. Trying to drive until fuel and Battery power was exhausted would cause the car to become a giant paperweight. Just like driving a diesel car until the tank is completely empty, something that shouldn't be attempted.

I did hope Toyota would have ensured that either scenario would be almost impossible to get into, but go into some form of protection mode.

Personally i haven't yet got to 0 miles range, as the low fuel message overrides the display on the dashboard.

Some 14 years ago my dealer told me a Gen 1 Prius owner had put diesel in his car and allowed the car to attempt to restart so many times the HV Battery was too low to start the engine after it was cleaned out.  There was only one special charger in Europe, which was in Belgium at the time (IIRC).  It took a month to 'que up' for it and for it to be brought to the UK.

Around 2007 one of my drivers in a Gen 2 Prius did the same, and there was still only one charger in Europe.  It also took a month to procure, and at that time the HV Battery had died completely, and would not recharge.  A rather expensive new Battery was fitted!

A couple of people I chatted to at the time on the Yahoo Prius-UK group had run out of fuel in Gen 1 & 2 Prius, and reported it seemed to go into a more severe economy mode when drawing the last few gulps of petrol.  In one case, the owner managed to EV to a petrol station less than a mile away.  No harm done.

I've not yet come across anyone with first hand experience of a Gen 3 running out of petrol, so not sure if anything different happens - anyone here actually run out? (not that I'm suggesting anyone tries it!).

Thanks for correcting my misconceptions, definitely something i will not be wanting to try.

Maybe a pip owner can tell us what the situation is with those.

The Yaris hybrid uses the same engine as the gen 2 Prius except that it has supposedly been modified and tweaked to make it more efficient. It certainly pulls around a smaller car so it should fair better than the Prius Gen 2 except that it doesnt seem to be better at all when you look at the Fuelly web site figures. It has to be aerodynamics

Partly that, but the basic problem with the 1.5 is that it doesn't quite have enough torque to drive the car at a low RPM so the HSD either needs to take power from the Battery or run the 1.5 at a higher RPM which obviously uses more fuel.

I reckon the change to a 1.8 was in response to this, and most people who've gone from a gen2 to a gen3 have remarked how it's quieter at speed (The aerodynamics probably helps a lot there too tho' as you say!)

re. running out of electricity/petrol, if the traction Battery hits Zero then it is game over with the HSDs; You can't start the ICE to recharge it and you can't jump it; The Battery needs to be recharged with a specialist recharger, or changed.

If you run out of petrol, but still have battery charge, you can just put more petrol in and it should be okay. I forget which ones do what exactly, but IIRC the older HSDs will just stop dead if you run out of petrol, even if you have charge, while newer ones will let you run for 10 miles or down to a certain level of charge before shutting down completely. I didn't know that there were some that would let you run until the traction battery is dead tho', that's new to me! I suspect that is not intentional given how much more catastrophic draining the traction battery is vs draining the fuel tank!

67 MPG on my Yaris Hybrid, doing my daily 90 mile round trip in to central London and back. 

That's better than a BMW 116d automatic (55 mpg) I had on loan a couple of weeks ago. Plus I preferred the silent hybrid in town, better ride. But at times on the motorway missed the diesels torque.

I had read that the change to a 1.8 was down to the fact, that some hilly areas were a real problem and the cars struggled. As well as motorway cruising was more efficient with the larger engine.

I can't believe that guy did the same thing a second time, the only time i have ever run out of fuel was with a faulty gauge and miscalculating range with a full tank. Fortunately my speed was low when the diesel ran out. After  that I paid more attention to the trip counter.

Oooh, nice! :thumbsup:

I didn't think the Yaris HSD was too bad for the torque tho'; I know the HSD's I've driven have been fun to launch off the line, plus the ICE can redline almost instantly if you floor it instead of having to wind up like engines mated with fixed-ratio gearboxes.

They do tend to get noisy as heck when you do that tho'  :laughing:

I know it makes more noise when compared to accelerating on electric. Just don't consider it loud. The Yaris isn't as quick as my auris, but lasts longer on the electric and the boot has more room than my mk1 auris.
