If you can shift to neutral while driving, you can coast if you want. Can you shift to neutral while driving in an EV?

I can in my Ioniq5 and VW ID.4

Tell that to Porsche. https://www.greencarreports.com/news/1138776_one-pedal-driving-in-evs-isn-t-efficient-says-porsche

And even if 1PD were the most efficient (I don't agree that it is) - that's still no reason to not offer an option to turn it off (permanently or not). Especially for a company being built on options, customization, and choice.

The Ioniq5 always defaults to non-1 pedal drive after turning it off or reversing. The Ioniq5 forum attributes this to how Hyundai had to EPA test the vehicle. It’s more efficient in “traditional 2 pedal mode” since the front motor will disconnect so they used 2-pedal driving to get the EPA range number. In order to maintain compliance the vehicle has to default to that mode.

I bet Slate qualified in 1 pedal mode so it has to be the default. Developing the motor behavior profiles for 2 pedal mode would add cost and controls so they didn’t.

As a 2-year EV veteran I support their choice. I almost always just stick the Ioniq5 into one pedal when I start driving and I always miss the mode in the ID.4. With basic cruise you’ll be fine without 2 pedal mode on the freeway but be prepared for an adjustment period and realize slow small lifts are your friend.

Personally, I would prefer to have an option to disable 1PD. My other car is a Fiat 500e and I really enjoy its standard mode. But I fully understand why Slate would elect to have the one drive mode. Every feature or capability is cost. Development cost, testing cost, documentation cost, six hundred different forms of analysis and tuning cost.

Look at 1PD specifically. With 1PD you have all operator control inputs to the motor come from a pedal position sensor. Below some mid point the controller is commanding power to the motor based on where the pedal is. Above that midpoint the controller is commanding power from the motor.

When you want a more standard "coast" mode you now need to pull an input from a brake pressure sensor (or a second pedal position sensor) to feed that motor controller. Now your brake is controlling both the motor and the hydraulic brakes. That's requirements, that's test, that's analysis and tuning, that's documentation, and that's cost. Doesn't matter if the approach to do it is well understood - it's still cost.

Maybe, hopefully, if the technical data is available there may end up being an aftermarket solution, or with enough demand signal Slate may just bite the bullet to make it happen. But, when you're chasing cost hard, it comes with design considerations.

I’m in the same boat. I wish I could turn it off, but I know I’ll get used to it.
Hell, I learned how to conserve battery while being fast in an EV race car and ended up being faster in that car than my teammate who was much faster in our ICE car.

I'm all-in for Buttery 1PD.
It's the very best kind!

I hope the employee who coined this phrase gets to see this post!

"All vehicles will be shipped with a reasonable amount of charge to get to where you need to go."

Slate Nuance strikes again.

Enough to get to a Supercharger.

There's a post with a good shot of the dash bulb check. It has a green icon of a foot on a pedal and the word "off."

So it's either planned as optional, or deleted. I would guess the "opd only" response is until the EPA comes back. Then they can say two-pedal has been added. Because there ain't no spectrum like a car forum.

And…Cadblu for the Win!🏆

From the AMA, they said there'd be threaded holes in the corners of the bed for tie downs. I'm thinking that one of those might make a good mounting point for a bracket that would hold a spare upright like the old Fords.

Of course it'll probably have to be made not bought.

Could be a simple cottage industry for a Slate owner/hobbyist to start up.

I drive a Bolt EUV and love 1PD for around town. I hate 1PD when I am reversing or driving on the freeway. The regen makes it too jerky when trying to slow down gradually and smoothly. Not a deal breaker, but constant 1PD will annoy me, even if buttery.

You need to practice better throttle control, I’ve been using OPD for 5 years, 2 of which are with my Equinox EV set to high, I do not experience what you describe.
It’s really great in the mountains, I almost never have to touch the brake pedal, seeing the range and % charge increase on long down hills is somewhat satisfying.

Here you go. I took this shot in my secret spy Crayola uniform.

Ok, yellow. My bad.

So they know.

Don't make me get out the MIG welder. Because my L2 will be plugged into that outlet.

Yeah there is -- lift up on the stalk for reverse, pull towards you (and probably hold for a moment) for neutral, push down for drive, push in on the button on the end for park. I did see a big boxed 'N' on the stalk selector so it's either going to be a push-in or pull-towards activation.

Personally I'm looking for the First Responder/Emergency Response/Towing guides they'll have to publish at some point in the coming months.

There's got to be a neutral position for going through car washes too.

Is there any other reason for Neutral?
