About 6-7 km on the road driving. Every morning my RAV’s battery is empty when I leave the city road behind. Running in road speed (95 km/h) loads the battery full during 7 km drive. When the battery is full the fuel consumption decreasis some 0.2 l/100km.
 
You will find that our ICE or internal combustion Engine needs a few miles to break-in and loosen internally. I belonged on the Tacoma Forums and I owned a 2.7 liter 4 cylinder model, and many members on that forum complained that their 4 cylinder Tacoma did not give them the EPA stated gas mileage in the early miles of owning the truck. In time with more mileage the engine would perform better and the gas mileage would climb. Toyota builds their engines with very tight tolerances in the internal bearings and rings of their engines. Our engines are highly engineered to perform and meet mileage ratings, and with more miles on the engine you will find the gas mileage should climb to the acceptable levels.

I'm doing 7,2L/100 km since May, I'm afraid of what I will see next winter if you are doing 6,5 in summer and 8,2 in winter. Also, I'm planning to buy studded tires (the new Nokian Hakkapeliitta 9), which will not help I suppose. I have a block heater installed, to help a little bit, because we have a chalet up north (now you know why I want studded tires) and we go skiing every day so I want a warm engine to help the fuel consumption and the confort. I'm not decided between Hakka 9 (studded) and R2. R2 seems to be a good tire for fuel consumption. Electric car drivers in Montreal area seems to love the Nokian Hakka R2, but because of the ice and hills, I think I'll go with studs. What tires are you using? Thanks!
 
I was going to install an aftermarket block heater from Etrailer, but it's not easy, the main harness for the high voltage Hybrid components is in the way and has to be removed to access the hole in the block, an easy install on a gas model by just removing the air box.

Wow, the heater block is just a screw in heater device that goes into the radiator... looks like they designed it to be way more complicated than it needs to be so as to drive business to the dealers - same as BMW and Mercedes.

Thank you for your replys. I did very gentle drive with slow start and stop then there is little improvement. 7.7/100km, 30.55mpg( I live in a manitoba Canada) on 120km city driving. Still not good enough comsuption. I found my bettary was not fully charged yet. There are 8 level of charging monitor but mine, maxmum level was 6 so I went dearshop, ask them why my bettery is not fully charged? Thchnition told me that's normal because of protect for the battery. How about your rav4 ?? Battery level 6 is your maxmum?

The block heater (not radiator) installs on the 2.5L 2ARFE/FXE engine in the engine block, it's just a round hole in the casting and uses a cartridge style heater coated with thermal paste, it's not threaded, just uses a retaining clamp.

OK, thanks for the link. So does the install require coolant or engine oil top off? Or does this heating device sit on the engine surface?

I have seen the Subaru heater block and it looks like it would either be inserted into the engine block or the radiator... might have been engine block.
 
Is only 8 l/100, us 29mpg on 840km us 540 miles driving so i meet dealer, he said its nomal... i am so frustrating because of this. What you guys think?? Is it nomal? Or i need to go dealer again?? What is normal consumption for rav4 hybrid? Thank you!
Good to hear with gentle driving your mileage is improving, but I would have to say that yes you are getting mileage that is within normal range. Everyone's driving style, average speed, acceleration, braking, etc varies so mileage must also vary. If you look at attached screen shot from Fuelly you will see there are 268 Rav4 Hybrids that have their mileage tracked. The average is 7.3 L/100, but as you can see, only a few cars actually are at the average, and there is a dispersion in mileage as everyone's driving condition & style varies. For all those that are getting worse than 7.3L/100, that does not necessarily mean that there is something wrong with their car. It is likely just that their driving conditions/style are more challenging.

It is better to not charge to 100% or discharge to 0%. You likely never see less than 2 bars left (I never have) and you also likely not to charge all the way to the top 2 bars, unless you brake on a long downhill.

There are two versions available. Get the cooleant heater it has much more effect. My subaru started at 43C whilst the rav4 with the other heater type obly gets like 20C in the same conditions

Thank you so much !! Answering For the Same questions aredy have writen this homepage because My English is no good enough so my reading is so slow. Thanks. One more question, what ICE mean for rav4 hybrid you said.
 
ICE internal combustion engine = the petrol motor
Had to look that up as a newbie user on this forum to.
 
The biggest enemy of fuel economy is erratic driving style. I own my RAV4 since March and I've clocked 22k km since then. The fuel consumption that I get is between 2l/100km and 14l/100km. It really depends on so many factors, but I've figured out that, if I do not think too much for it, I get better fuel consumption (also it may sound very strange but in normal mode, I get better fuel consumption, I've observed it on 5 tank basis, same routes, same ambient temperature). My average is 7,7, because of the fact that I drive fast when I am out of the city (150-160km/h). Last few weeks I had 2 tanks of only city driving and my average was 6.3l/100km. One advice from me - drive it like a normal car, it was optimized to be driven like that. Just try to predict the traffic - coast whenever you can, avoid longer than 5-10 seconds rapid accelerations and try to maintain stable speed (requires a steady foot), when you get up to whatever speed you want to get to (that is a key factor, because the sweet spot for a hybrid is to drive it on the edge - ICE produces barely enough power to move the car and 1-3kW of power are redirected to charge the battery, in this mode at 90 km/h I can easily get 4-5l/100km). Also avoid using the Cruise Control on roads where there is a lot of traffic - it produces a lot worse fuel consumption.

When I put my accerelation with steady foot ev mode is never pop up eventhough I drive 60km
When I takes off the accerelation then ev mode is pop up on my screen.
