E-Pedal is good for urban driving, but on the highway it will waste energy. That's why I'm asking how much regen there is in the D and D-Eco modes with e-Pedal off.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Can't say how it compares to the old LEAF, but the regen level is -0.20g in "E-pedal" per MT's comparo with the Bolt and Model 3: http://www.motortrend.com/cars/tesla/model-3/2017/the-automobile-2-0-chevrolet-bolt-ev-premier-vs-nissan-leaf-sl-vs-tesla-model-3-long-range/
The Bolt's slightly stronger in 'Low' (-0.21g), -0.26g 'Low + paddle', and -0.19g in 'Drive'. The Model 3 has considerably less decel, -0.09g in 'low regen,' -0.16g in 'high regen'.

Is there any way to know how much of the E-pedal deceleration is coming from regen versus friction braking? Also, I wonder how much of the regen in a new LEAF 2 will go away as the battery degrades. Will it all go away eventually?

LEAF Spy should give us that info although its not all that certain that LEAF Spy will be available on the 2018. I reported that Nissan had taken steps to lock down the CAN BUS based on failures from another model when plugging in OBD devices by my local LEAF Tech last Summer.

But others stated that what LEAF Spy did was not as invasive and it would still work and Jim did post a shot of of a 2018 he plugged into so hoping LEAF Spy continues!


As far as long term degradation? That is anyone's guess. IMM, there never was a reason for it to go away under any level of degradation so I doubt its a physical barrier; simply a SW misstep.

--- CAVEAT ---
I really enjoy the new 2018 leaf and I am a loyal Nissan Leaf driver, I also really enjoy the tech of Tesla's autopilot and was hoping to see a few of the features mentioned below included in the ProPilot.

I took delivery of a blue 2018 SL leaf February 7th in Northern Virginia. I have only driven leafs as my daily car since May 2013.

ProPilot:

I have used Turo to rent three different Teslas to drive from DC to New Jersey. I am a huge fan of Tesla's auto pilot. A few point have come to mind in the 300 ish miles i have driven so far with the ProPilot in my vehicle.

ProPilot does not pick up turn lanes that it comes upon. For instance if you are driving on a highway at 65 miles an hour and you come up on a right hand or left hand turn lane the auto steering turns off because it isn't able to sense the the solid line just switched to dotted. The auto steering will turn back on once you are back to solid lines.

ProPilot does not change lanes! This sounds ridiculous to some but I really really enjoy Tesla's lane changing ability and it's ability to re-find the lane markers. When I turn on my turn signal to change lanes with ProPilot that auto steering turns off.

The adaptive cruise turns off in stop and go traffic. I am having to preemptively press the "RES" button to have the adaptive cruise start again. I sat in an hour of stop and go with the Tesla on route 78 once and never had to re-engage the autopilot

In comparison, I find I appreciate the Prius Prime's adaptive cruise control most in stop-and-go traffic. It will "adapt" all the way down to something like 1 MPH. If it comes to a complete stop, you do have to manually intervene by tapping the throttle when you want to resume moving.

LEAF is same way. It will come to a stop and resume set following distance but it times out after 5 seconds or so and needs to be "tapped" to get going again.
