Leaf does have variable regen. You regen more by pressing the brake harder. What we don't have is the ability to change the amount of regen for a particular amount of brake press.

So, is the ask that Leaf should regen more for a given amount of brake press ?
Personally, I do not want an regen on the brake pedal at all, while in ECO mode. I'd be very much happier if I could get full regen on accelerator pedal lift.

This is how Tesla does it. I look forward to my Model S being delivered next summer ;)

so would i, but that would be "too much unlike" a gas car.

what i really want to know is who thought we wanted our LEAF to be anything like our gas cars?

I'd like to be able to choose how "wide" the glide band is on the accelerator pedal and how strong the regen is at foot off pedal.

There are times on flat ground or a slight down slope I want to glide as much as possible and it bugs me how touchy I have to feather the pedal.

There are times when I want more regen than foot off pedal currently gives.

I don't want more regen through the entire pedal travel, I just want more regen at the very end of travel and a wider dead spot between regen and applying power to the wheels.

NIssan, they admitted they went to great lengths to make it seem just like an ICE, so much so they took away some of the coolness of an EV. As a result quite a bit of regen is wasted to friction brakes which is very sad for an EV, if you drive in a hilly area or stop faster than a turtle or even like more spirited driving then significant regen is lost, this is a fact and a very sad one. In addition having the ability to have more off pedal regen can be a very cool driving experience. Another thing they went overboard on was the old fart 1970's EPS that feels like steering with a rubber band. Nissan has publicly admitted they did this intentionally and like so many other things they ignored from long time ev drivers they dumbed the car down to much. I'm sure it is perfect for the Japanese market and 1980 Cadillac drivers but sad for anyone that has driven a modern car with even decent steering.

Nissan.

I, too, wish there was much more regen available from just the accelerator.

Guess I'm in the minority. I'd rather the accelerator had NO regen unless I put it in a "hill" mode. anything else is just trying to be a fake ICE to me. I like to glide and hate having to feather the "go" pedal to achieve it. If I want to slow down, I'll push the brake.

that would require too much button pushing. what is wrong with having all of it on a single pedal? as it stands now, i am constantly shifting from eco to neutral to drive to eco, etc. its a pain but i can verify that it does improve my performance.

problem is that is takes a lot of concentration and planning which is ok to a degree because that is the nature of hypermiling but I could do it in the Prius on just the accelerator for the most part because the benefits of shifting to neutral were not that great. in the LEAF however, the difference can be huge if done correctly

Huh? Why would you shift to neutral if you want "it all on one pedal"? Just stay in ECO, feather the pedal, and be done with it.

well mostly because unless you are 95+% SOC, "deadbanding" (driving when power meter says the motor is neither generating or consuming power) still has a significant drag on the vehicle. i can coast much farther and maintain my speed much better in neutral and no amount of pedal play will match that performance.

ask anyone who gets 7 miles/K they will tell ya how it works

Then why do you want it all on one pedal? That was MY argument. I want to just let off the "GO" pedal and coast. Then hit the brake if I want to regen and slow down.
