Yaris motorway mpg ?


Countryside
 Share

Recommended Posts

I’ve owned a CHR for nearly 3 weeks but going to order a new Yaris hatchback I live in the countryside small villages country roads but go to friends relations on the motorway 50 miles there 50 miles back . If I keep at 60 to 65 mph on the motorway could I get 60 mpg from the Yaris ? I understand it has a smaller fuel tank than my Chr I’ve had 550 miles to the tank in the summer can I expect 450 miles in the Yaris ? Many thanks for your help

In summer it's capable of 60mpg at motorway speed quoted. Winter would probably be less, haven't gone through a winter with my new car yet, other members can comment. It can easily get 450 summer miles. 

In another post u mentioned not being able to decide on design or excel trim; design have better comfort tyre profile, the excel has less comfortable tyres though better kit as u are probably aware.

* Unrelated to your question, for cyker who reads everything regarding MK4 posts, especially mpg - one of his specialist topic! The memory foam lumbar support that I had been using more or less restore my back to the state before the mk4. So it's pretty much the seats on the car doesn't have enough lumbar support for me. Did tried the rolled up towel before the lumbar support, it did help a little, but it has to keep maintenance each time. Proper lumbar cushion required.

I got my Yaris Cross petrol hybrid just less than a month ago, so my mpg figures are just one-offs.  One 250-mile motorway trip at 70-75mph gave me 51mpg, just the same as my former diesel Renault Captur.  Since then I have been doing rural A- and B-roads at 40 to 50mph and getting 67mpg.  I suspect the Yaris wil do better due to its aerodynamic shape

FWIW, if you are going to drive at that speed with 4th gen hybrid, you'll never beat what a standard ICE can do. The car will never go into EV mode, except some longish down hill stretches, maybe.

That's the sweet spot.

The Yaris is not a particularly aerodynamic car, but it certainly isn't a brick either.

Does the smaller wheels on the icon and design get more mpg ? So the smaller wheels are a better ride than the 17 inch on the excel ? Thankyou for your help yes I like the spec on excel sat nav keyless folding mirrors blind spot etc and love the alloys design with the met silver paint

Motoray driving at 60 - 65 MPH should return over 60MPG in my experience driving mostly on A roads, driving just below 60MPH (the speed limit) I get around 68-75MPG. And I live in a hilly part of the country and I do mostly long runs. Incidently engine performance is at its peak after 15000 miles, MPG increases as a result. Of course I expect that will decrease in the cold chilly frosty weather we now have.

Not really due to the tyre profile, the rolling diameter's are very close. The difference in ride comfort is down to the amount of extra sidewall you get with the smaller wheels. FYI all the Yaris cross now start out with 17" rims, Or so I'm informed.

Comfort of tyre more due to the tyre profile - more sidewall is tyre profile. The 16" is 195/55/16 where as the excel is 205/45/17. I did originally wanted the excel for more kit, though at one point hud and JBL were no longer an option so opted for the design spec.

I have a Yaris (not Cross) Excel, 22MY. If I'm in no rush I do 54 on the motorway, get 80+mpg summer, 75+ winter. This week I had to drive 230 miles each way on successive days. Chose to cruise at 64 there, 70 back. MPG figures were 72 and 68 respectively. The key to getting decent fuel consumption on a hybrid is to keep the speed down, so the electric motor is used more.

I’ve have back problems so need a comfortable ride like my Chr such a shame design doesn’t have keyless etc

I have been experimenting with tyre sizes and types and the difference really is between 2-4mpg, not anything significant. The feel how the car drives maybe more pronounced if you know your car well. 
For the seats, for those without lumbar support you can try to adjust the height of the seat base up or down , then re adjust backrest angle.
When adjusting seat base height you are changing the base rear end vertical position and this changes your back support. 
Motorway drives in any Toyota hybrid can be more efficient than standard petrol or diesel cars  as long as you don’t mashed the pedal to the metal. The car will switch better ev and hybrid all the time and the ev motor will help propel the car even at high speeds so the petrol engine is less loaded.

Yes, I expected that, but it's still very acceptable compared to my diesel cars doing the same regular journey.
The Battery was certainly assisting the engine on the climb to Shap Summit, but was fully charged again by Penrith! 😀.

Funnily enough I just started a new tank of fuel (Esso Supreme E5 after BP Ultimate E5* - Car is getting spoilt!! :laugh: ), and immediately burned up the M1 so can give some relevant figures:

I was trying to do 70mph... ish... as much as possible, and was getting mid 50's indicated for the mpg for the first half of the M1, but ended the journey at about 65mpg (Clawed some back in the inevitable M1 Smart Motorway For No Reason 40mph zones, and the last stretch heading up the A5, where the engine could use the electrics more for coasting and not just helping me accelerate harder :naughty: :laugh: .)

For comparison, in summer, at a slower pace (high 50's/low 60s mph), I can usually end the journey at mid-high 70's indicated mpg, so the cold does seem to affect it a lot.

 

 

*Interestingly, the Supreme seems comparable to the BP Ultimate in terms of NVH at least, so despite them not being ethanol-free any more, it seems their additive package is still less dakka-ry for the engine. Out of curiosity, do petrol have summer and winter blends like diesel does...?

If tyre size is a issue the mazda 2 hybrid comes with smaller tyres and may have the spec you require.

Many thanks I’ve looked at the Mazda 2 hybrid yes has the smaller wheels and heads up display on windscreen on top select version but I prefer the looks and seat trim of the Yaris excel and the 17 inch wheels do look so good imho

Could buy the excel, if you find the ride uncomfortable, an option is to source a smaller set of wheels/tyres - Mr cyker has done that. Too much hassle for me and also didn't have storage space.

Petrol has summer, winter and intermediate fuel blends.  See the attached spec sheet from Greenergy.  Greenergy distribute Esso fuels and deliver to most supermarkets.

We have a Yaris on order so cannot answer from that experience but we have owned a Superb PHEV for over 3 years now and can give you an idea based on that.

When we go to the Scottish Lodge twice a year its a 1000 mile + round trip and with no opportunity to charge the car it becomes a traditional hybrid after about 350 miles when the Battery runs really low. That means at least 650 miles are done in hybrid mode.

Its way bigger than a Yaris with way more power and we cruise at 72 mph on the speedo. On an average return trip we get about 57 mpg, in the 1.5 manual ICE Superb we had before (lighter and less powerful) on the same trip we would get an average of about 51 mpg.

Based on that I would hope to be able to manage at least 60 mpg driving at the national motorway speed limit, the Fabia that is being replaced by the Yaris does just over 60 mpg in those circumstances as did the Nissan Note we had before that.

Thanks; I knew it was a thing with diesel because it's thicker and tends to gel up when it gets too cold, but wasn't sure if petrol had similar issues!

Anyone got a Yaris cross icon ? Saw silver one this morning with the silver 16 inch wheels looked very nice

Years ago diesel could get wax forming in it which obviously would stop it flowing. I don't know if it is still a problem with modern fuel formulations.  Petrol doesn't have a problem with flow but is made more volatile in the winter to make starting easier.

YC - summer we can get about 80-70 MPG indicated driving at 50-60 MPH.

Yaris GR Sport (18") I can get 80 MPG indicated in warmer weather driving at 50 MPH, but now it has gone cold and I'm using the heater more, that has dropped to 50-60 MPG.

I'm still optimizing my heater usage. Less heat, more fan seems to be the deal (set between 20 and 22, and fan at 4 or 5 bars, set to floor and windshield).

I managed to get 60 MPG indicated out of it yesterday, despite heater usage and a lead foot. Most of the journey was at 50 MPH. I was trying to drive nice but some ***** thought I could just drive through the cars in front of me and kept flashing his lights, so when the road opened up... LOL

If you sit for a long time not moving but with the heater turned on, don't be surprised to see 30 MPG.

I find the same with mine - The irony is the engine is so thermally efficient it doesn't generate much waste heat and looses it quickly when the HVAC is using it to heat the cabin up!

Toyota UK really dropped the ball when they omitted the heated seat option - I'm sure that would have helped a lot with keeping the efficiency up...

Would it be worth one of the plug in heated seat covers the likes of lidl sell?

I'm too scared to because of all the explosives in the seat! :eek: 

(The car has centre airbags to stop the driver and passenger smacking into each other in a side collision - I don't know how anything that wraps round the seat will affect how it 'deploys' (i.e. explodes) and don't want to find out!)

I did have a 12v flat seat heat panel that someone bough me 2 christmases ago, but it was a bit weak and kept sliding out of place, as well as sliding me out of the seat (I didn't fix it to the seat as instructed due to the aforementioned explosives), so I stopped using it pretty quick.

If it really bugs me, my Plan B is to try one of those heated vests things (Which will also have the advantage of keeping me toasty outside of the car! :biggrin:  ), but I'm less traumatised by the 20+mpg drop now that I've already been through it so we'll see...!
