Please check my latest videos for fuel consumption test with warm temperatures.
Low temperatures does affect the efficiency of this car.
When needed, the ICE will charge the battery. This can happen in every ICE mode.
This will make your engine consume more petrol for a certain time. This time depends on the hybrid mode selected, your driving style and speed.
For example on the highway (100-120 KM/H) :
The best mode is the hybrid auto. The car will switch between EV and ICE with a little battery charging.
Hybrid hold will keep the car on the ICE with some battery charging.
Battery charge will literally empty your fuel tank and will never switch to EV.
Additional details
In summer :
EV : 35-40 KM
In winter :
EV : 25-30
With heating, around 20-25 (i m usually not using the heating, unless extremely cold)
In General :
Hybrid Hold : around 600 and between 5.5 - 6.5 L / 100 KM
Fuel tank : 40L
Battery capacity : 8.8 kWh
Usable battery capacity : around 7.7 kWh (the rest is reserved as battery buffer in order to avoid too much battery degradation)
Home charging price (battery) : around 2.50 CHF
Fuel price : 1.63CHF x 40L = 65 CHF
So it costs around 5-7 cents / KM with in EV mode.
Around 11 cents for the "fuel" mode.
Home charging makes running the car less expensive.
Some malls offer free EV charging so it stays a good deal.
Unfortunately, some private companies offer an extremely high price for charging (with or without subscription), that is as expensive or even more expensive than fuel. So companies a taking advantage of this new market. As a PHEV owner, i can avoid them, which is not really the case for pure EV owners who have sometimes no choice.
Also private companies have all their own system for paying. Using credit card, or smartphone apps, subscription cards, SMS... All this has no sense. There are no fusions, no collaboration, no good prices.
Some take in consideration the duration of the charge, some the kWh consumed, or even both a the same time. I personally avoid all those places.
For example :
This car takes around lets say 120 minutes to charge.
With our Swiss electricity provider in Geneva with public charging spots, it would cost :
Without subscription :
16 CHF (instead of 2.50 CHF at home)
With subscription :
59 CHF per year
+ 0.45 CHF / kWh (3.96 CHF)
If i charge at home, 59 CHF = 944 KM.
So just having the subscription makes me lose that many KMs.
+ of course the 0.45 CHF x 8.8 kWh = 3.96 CHF.
So not only the price of the charge is around 60% higher than at home, but you have to take the 59CHF/year.
It is a complete rip off.
Fortunately all are not the same.
To finish, i find that Toyota HSD is a bit more fuel efficient than Audi for daily city drive.
Actually, both motors seem to work more together and alternate more often in order to achieve good fuel efficiency and battery regen. But Toyota has 20 years of experience so no surprise there. Of course the Yaris HSD is lighter and less powerful, so that helps.
The switching of EV to ICE is also more fluid, but this may be because of the CVT transmission.
If any of you may want a latest Yaris HSD video, i could make it.
