Got my EUV yesterday. I've had a 2015 Leaf for four years, and I always drove in its high-regen mode (called 'B'; it's not one-pedal), so I'm very much already accustomed to using regen as a mechanism to avoid braking.

But there's something I've always wondered, and that curiosity is magnified by the increased level of slow-down in the EUV as compared to the 2015 Leaf's 'B' mode.

Driving in one pedal in my EUV feels like I'm always dragging a boat anchor. While I totally see the advantage of it in city driving, does it actually have a detrimental effect in highway driving if going a good distance at an essentially constant speed ? (I can see the advantage in stop-and-go SoCal freeway traffic)

Just watch the real-rime kW consumption, it generally doesn't change between D and L/1-pedal.

I noticed that yesterday. My leaf didn’t provide an actual number so that’s sort of cool.

Short answer, No. This topic has been asked and answered here at least fifty times (no exaggeration!)

Driving in one pedal in my EUV feels like I'm always dragging a boat anchor.

There are some who, without any substantiation, feel they get more range and/or regen in D. They miss the old ICE burst-and-coast driving style.

It's true that if you just take your foot off of the pedal the regen braking can be quite strong. But you can modulate it for the first little bit of pedal travel. In fact if you move your foot slowly the fade from brake to acceleration is quite gentle. It takes some getting used to but you can get quite a smooth ride with some practice. Also, the cruise control seems to work really well with the L/1-pedal and fade from brake to power without any kind of jerkiness,

Agreed on all.

My EUV doesn't seem to regen more than 8-9kW before engaging the friction brakes in cruise control though. Anyone else experience that ? I'm talking about a steep hill where I can regen 20-25kW by disengaging cruise control and adjusting the pedal pressure in one pedal mode, or I can get 8-9kW before the car engages the friction brakes to slow me down.

Yep, I see the same thing. I am sure there is some reason that is tied to some regulatory agency somewhere.

Unlike the Tesla Autopilot bros, I don't use cruise control much. Too much traffic around; I have to pay attention. But I have tried it (in a '17) off-peak with and without L (one-pedal), and when coming down a typical freeway grade (2-3%) I've seen the regen spike as high as 10-12 in L vs 4-5 in D.

Interesting, based on this thread I'll give it a try disengaging L.

I use cruise control all the time, and SuperCruise. But I don't live in a big city, and never will.

 

[GeneL]

I think something changed in the newer models. I don't think my car can use the friction brakes for cruse control. I drive in L all the time and there is a very steep hill on my drive home. With cruse engaged and in L mode I get 32-35 kWh when coming down that hill.

Without training a driver to be exact and on some special route that can be calculate I'd think it doesn't matter if one uses cruise control. The problem I have with one pedal is how agressive it is. Sure I like it to stop but any devation when trying to maintain a speed or adjust can take effeciency.

That's why I like to use it in town, but switch to D on the freeway. More comfortable.

You, my friend, have not done battle with stop-and -go SoCal freeway traffic, I bet.

I did one hour each way for 17 years, and then I got a Tesla with auto pilot and it was life-changing.

I’ve been work from home since Covid, and knock-wood Hopefully that will stay that way for a long time, but if I still had to commute, I definitely would’ve gotten Supercruise.

Regen insn't perpetual motion. There is a huge loss going from tire to battery.

Nobody disputes that. But using the friction brakes simply converts motion to heat and dust particles. Regen recovers some of it as usable energy. It matters, though it's better not to need to use either aggressively.

So glad we have an old Bolt, with no Super Cruise. I would hate having spent extra to screw up CC.

I've done my share of commuting. Though the longer commutes have been mostly using transit (2 hours on the commute bus each way is a nice nap in the morning and time for memos and reading in the afternoon) because peak traffic was ridiculous and driving (when I had to do it) not much faster, if any. Sure, off-peak, driving is much faster than any mass transit, but in good cases it can be competitive at peak times. Now retired and glad that my occasional consulting gigs can be done mostly online from home.

My worst "commutes" were both on I-80. Work trip to the Bay Area with a fleet-issue Honda Insight (gen-1, stick) took 2 hours going, 3 hours returning, 90 miles each way with maximum speed 50 mph, usually under 20. Got almost 70 mpg. If I have to do that trip now, I take light rail to Amtrak and ride the train. And when my Mom was in assisted living, it was 50 miles through Sacramento; returning in the afternoon usually took at least 2 hours, and in the stick-shift Mazda produced about 28 mpg while the Prius would get over 50.

It is a matter of personal preference.
Once on the highway and cruise control is on then I will generally disengage one pedal mode in the EUV or engine brake mode in the motorhome because I like to be able to disengage cruise if needed for a little coasting without a huge braking force occurring right away.

SuperCruise has had a very positive effect on my life and I'm quite happy with it.

I'm talking about regular cruise control and adaptive cruise control will both cap out regen at ~8-9kW when controlling speed down a hill. SuperCruise uses adaptive cruise control, so yes, also applies but I don't think SC is the cause of this since it occurs in regular CC.

Yes, I'll second that. I figure it exercises the friction brakes which otherwise don't get used.
I'm in the Great Lakes region so not worried about the bit of regen that I might miss out on....for those in more mountainous terrain, I get it.
