Tesla Cybertruck gets less than 80% of advertised range in YouTuber’s test::A YouTuber took Tesla’s Cybertruck on a ride to see if it can actually hit its advertised 320-mile range, only to find out that its could only reach 79% of the target. When YouTuber Kyle Conn…

Is hypermiling different in a hybrid or an EV compared to say an old manual transmission ICE?

EDIT: To be more clear, I guess I was more curious about techniques used. I already am aware how much waste heat and energy there is in ICE vehicles.

    One difference is EVs have regenerative breaking. Using your brakes in an ICE is 100% wasted energy, while regen breaking in an EV returns some (I don't know what percentage) of the car's kinetic energy back into the battery.

    Hybrids have regen as well. Some phevs and some evs let you set the regen strength so you can either brake by letting off the accelerator (highest return to the battery) or you can just coast (lowest return) or somewhere in between.

    For more info, look for one pedal driving. If either my current or last car had adjustable regen I'd probably be able to do even better with efficient driving.

    It's far more effective in an EV. With an ICE about 80% of the energy is just generating heat so you've only really got the remaining 20% that you can influence.

    I don't think that's true. The issue is the amount of storage available for the regen to go. With a regular hybrid you have enough battery for maybe a couple of miles on battery depending on several factors. With a plug in you have anywhere from 15 to 30+, I think the latest prius was supposed to have something like 100 miles of range. With the larger battery the regen can be more effective on the efficiency.

    It's also dependent on the strength of the regen. There is what people are calling one pedal driving when the regen is set as high as possible, the motors will immediately start slowing the vehicle as soon as you let off the accelerator. The regen is also way more effective in the city. On the highway you'd probably want it set as low as possible. I don't yet have a vehicle with adjustable regen so I haven't personally tested out various scenarios to figure out what is more efficient.

    The regen level probably makes no difference if combined with already efficient driving. The idea of coasting by letting off the pedal fully in an EV is flawed. You "coast" in an EV by holding the pedal in a neutral power setting.

    I've worked some hypermiling concepts into my driving but I don't really go full on with it. I still haul ass on the highway and will gun it when needed.

    The easiest things people can do are overinflating your tires by 10-15% along with watching both upcoming stop lights and the brake lights of the cara in front of you and not just the one directly in front of you, when it looks like traffic is slowing down, let off the gas and coast. I coast as much as I can, especially towards red lights, stop signs and highway congestion.
