> high accelerations

Acceleration does not waste energy (other than speed related things like wind resistance). This is a myth that is perpetuated without merit, but probably because it's typically associated with overall aggressive driving, which implies bad braking habits.

Max efficiency is typically near peak torque for internal combustion engines [0]. For EV's, electric motors are actually most efficient at higher RPMs [1].

Fuel efficiency can be measured by breaking habits alone.

true, but I'd bet a 100$ that people accelerating too fast do speed too long and brake too much..

I gun the shit out of my Tesla at a green light, but look far ahead and slowly ease to a stop using regen braking only. Regen braking and one pedal driving is a nice incentive to not waste energy with brakes, and as EV's become more popular, I bet driving habits will become more efficient generally across the board.

Just curious, do you have stats on your watts per mile efficiency you can share? How it compares to the EPA estimates?

[JeffL]

244 Wh/mi over 17,000 miles in a Model 3 LR. That's really close to the rated 310 miles for the 75 kw battery. The vast majority of my miles are driving 72 mph on the freeway.

you know I was talking about ICE. Electric motors are a lot simpler so wild change in momentum is probably free and as you say you have regen braking..
