Maybe the specifics has changed with over 10 years of Toyota hybrid generations, but I'm certain that with the iconic Prius hybrids, engine braking or B-mode is operated by using the electricity generated by regenerative braking, and sending that power to the smaller enegine generator (MG1) to run the engine as a vaccum pump. This braking affect is of course limited by the maximum power capacity of the generator, which is 54hp for the Prius. Maybe there's also a mechanical gear ratio reduction on the engine too. A benefit I feel that a PHEV has in spades is that long downhil mountain runs are a blessing given the larger battery capacity that can gobble it all up. Maybe until next time when the RAV4 Prime comes.

Hi Alex, 11: 45 I believe the speedometers on modern cars are set by the manufacturers to display a bit more km/h or mph from the true speed in order to help the drivers avoid speed tickets. For example if the speed limit is 60 mph and you are doing 60 mph the car will actually be doing 56 mph meaning you'll be 4 mph under the limit and there for you won't be in danger to get a ticket. Also that helps with the cruise control, if you'd suddenly started going a bit down on a decline the cruise won't immediately reduce speed so you get a small buffer there too.

Thanks for the content Alex, I love these types of tests especially on electric/hybrid vehicles. I think people have no idea of the effects of weight and altitude correlates with the mpg of the car, they just see the suggested mpg on the window sticker and assume it's going to be that the entire time.

Hey Alex. I am wondering about how you managed to get things such as inverter temperature from the obd2 port. I have used torque pro with an elm327 based Bluetooth adapter but can't get hybrid system info out of it. Looks like I need custom pids to do that. Any help appreciated

Right
Alex, This is a fantastic video for detailing the RAV4's capability but I would like to know whether this 'torture' video will be deleted when you inevitably put this 'low mileage, gently driven' RAV4 up for sale. ;)

Thank you for a great video. I'm from the UK and the mpg would differ with imperial measurements. It's nice to know that my RAV is well capable at towing. Also, we in the UK, have never had a fill up issue.

Very impressive engineering. Another great A\A video, though I wish you would have stayed below the tow rating. Sure enough, somebody will see your video and fry his RAV4.

Thank you for providing interesting and informative reviews. In the current situation they help even if I'm not always interested in the car being reviewed.

I wish I could fill up my RAV all of the way like Alex. I have to stand around and trickle in the last three gallons no matter the station I go to.
