Seems like using the brake pedal in various electrified cars behaves differently in each one. Anybody know of a site that might keep track of exactly what the braking behavior is for various models? It would also be interesting to understand what the various one pedal modes do in each vehicle. "B", for example, seems to have many different meanings. In BEV's it clearly just increases regenerative braking when you ease up on the gas. My 2010 Prius actually does less regen in "B" mode because it down shifts, causing more engine friction. I'm specifically referring to when do the mechanical brakes actually kick in vs braking via regeneration. I was recently surprised to learn that in the Tesla Model S, the brake pedal does not cause any regeneration but rather purely activates the mechanical brakes, almost making more aggressive One Pedal a requirement. My 2010 Prius, as far as I can tell, is 100% regen for the first (very) small amount of braking and then adds in the mechanical brakes. So I wrongly assumed this was how all of these vehicles work. I test drove a 2018 Leaf the other day and it seems to have 3 different modes that cause different levels of regen when you lift up on the gas. "D" gives very little regen (almost coasting). "B" mode increases the regen. E-Pedal greatly increases the regen. But I have no clue what the balance between regen and mechanical braking happens when I touch the brake pedal. Similarly, in my 2018 Volvo XC60, there is a "B" mode which also increases regen when you lift off of the gas. But I don't know if this is identical to slightly depressing the brake pedal or not. Using the brake pedal lightly definitely increases regen but does it also add mechanical braking? I can't tell. Also can't get info on whether leaving it in "B" mode all the time has any negatives on fuel efficiency.
