Yes, pressing on the "go-slower" pedal increases Regen, by design.

The exact mix of percentage of Regen and percentage of Disk Braking has not been well described here, I believe.

Remember, at 100% SOC you get NO Regen (so energy is wasted in ANY braking), but at 80% you do get the "full/designed" Regen effects.

At 100% charged, in ECO mode, do you notice the lack of the "normal" ECO-mode foot-off Regen?

Presumably, you should just be "coasting", unless Nissan applies the mechanical brakes :( to "simulate" the expected Regen.

I have same issues as EVNow. I drive I get 4.5-5.5 MPK. my SO drives its 3.0-3.3 mpk. She has also hit the "two's" before as well

Two things I can think of:

1. Since regen is not 100% efficient you should drive as if you had no brakes, and only when you have no other option then use regen braking. Yes this will be a slower trip overall since you dont accelerate toward red lights and you will be coasting a lot. I assume Eco mode is taking care of jack rabbit starts. How do you coast in a Leaf without regen?

2. You have no regen since you charge to 100% everyday, at least for the first portion of the trip.

It's a 3400 lb EV, driving style is going to make a huge impact on the numbers and I would not rely on the Nissan averages on short trips. Welcome to EV driving folks, reality of a heavy EV is taking effect. I wonder how many people that discounted SOC and real time KW/Ah gauges are rethinking the value of such accurate tools. It's going to take a long time before people start to get how weight impacts range and how one must really compensate for that. If there were proper gauges in the car one could see the instant impact of road variation and efficiency. That is the point of the pedal remapping on ECO mode.

ahh, no biggie!!

drive to pace distance between you and other cars, ignore the rear-view mirror, pretend your brakes dont work and do not regen unless you have to.

Went to Rairdon's today to pickup the plates. 64 miles of driving, about half of it on freeways. Rest of it above 40 mph. Didn't have to use climate control - since it was a sunny day.

I got 4.3 m/kwh.

Better than the 3.9 m/kwh we got at night out for dinner on sub-urban roads driving around 35 mph, using climate on the way back.

Why? Full throttle acceleration is identical in both modes.

True, if you absolutely floor it. I like better response with less accelerator movement, so D works better when I need the increased response. What can I say? I'm lazy!! :oops:

Granted, but it's greatly dampened at less than full throttle. Sometimes you want to speed away, but at something less than everything it's got. :)
