Road test reveals how much energy can EVs really recuperate

How are the energy recovered percentages calculated? They do not seem to be correct when you divide the energy recovered downhill by the energy used uphill, especially for the first vehicle.

Excellent read. Keep up the good work. Let's sort out the distinction between full-regen and mild-regen. And educate the public.

Tesla could use more regen braking. It would be nice if they have tested the Taycan with enormous regen braking

TBH, the test is utterly amateurish ... they did not consider cooling, battery capacity, charging capacity of battery etc.
Sure the end gets "the message" we all know for 100 years right, lighter = better, but other aspects like why Dacia regen is so small? Why city regen is so high?
Dacia has small battery with barely any battery temperature management ... in city there are short bursts energy of recuperation that the battery takes like a champ, but give it a long 500 m descent, and you will start to notice transition from regen to regular breaks ... because the battery simply can't keep up.

"If you're heading into hilly terrain, leave a bit of buffer in your battery rather than charging to 100%."

Yeah, this unformtunately is not how physcis work.
