R2 accelerator vs. R1

[RickRivian]

Curious if those that drive a geb 2 R1 and have either test driven an R2 or have one, can comment on the difference in the accelerator resistance between the two.

Background - coming from Ford (Mach-E, Lightning), where we can turn off 1-pedal mode and still have regenerative braking in all other driving modes. Test drove an R1 several months ago, and found the pedal had significant resistance, to the point where after a 15 minute drive both my wife and I commented on the effort required to push and hold it as compared to the Ford EVs. Not having the ability to turn off 1-pedal on the R1 was one of several factors in our decision to not swap the R1 for the Mach-E (biggest factor was too big for our needs, waiting for an R2).

Not looking for opinions on how wonderful 1 pedal is. Been driving EVs for 5 years that have great regenerative braking without using 1 pedal mode. Simply interested in the R2's accelerator resistance as compared to a gen 1 R1, nothing more.

Or, any chance that Rivian is developing regenerative braking with the ability to turn off 1-pedal?

If you have driven both and are comparing, please indicate whether you are comparing a Gen1 or Gen2 R1. I noticed the Gen2 required a lot more force than my Gen1.

Personally I love 1-pedal and wouldn't trade it for anything.

I feel that, once you learn to feather the accelerator to control acceleration and braking, it becomes second nature in about a week. It seems most that don't like 1-pedal driving are still fully letting off the accelerator all the time as if they're driving a gas car.

You have to be willing to learn how to do it and not constantly wish it drove like a gas car, because it isn't a gas car.

1-pedal driving is fantastic, and turning regenerative braking off reduces city range by quite a bit, so I'm not sure why anyone would want to do it.

Do some calf raises.​

For me it’s not my calf muscle that hurt it’s these. I use cruise a lot to alleviate it.

Not the question I asked. Whether you like 1 pedal or not isn't my question. And Ford has regenerative braking in all driving modes, so you don't have to use 1 pedal.

Been driving EVs for 5 years without 1 pedal and with regenerative braking.

Dude, just keep your Mach E and be happy.

Won't be doing that. Mach-E goes in 2027 regardless. Question is what replaces it - and it won't be a Ford.

Turn one pedal on and get used to it. Rivian hasn't said anything about being able to turn it off. I'm super happy with it in my R2.

Again, not the question. Question is how the resistance on the R2 pedal compares to the gen 2 R1 pedal.

It's a little lighter and less travel than the Gen1 R1. Don't have my Gen2 here to compare that also though

The accelerator feel is all software. It's mapped differently between the drive modes in the R1, and it's different in the R2.

For all purpose, the R2 has a more immediate feel - acceleration comes quicker without as much pedal travel. More like sport mode in the R1.

This is not inherently better or worse - you don't need a lot of force in any case, and if you're holding the accelerator pedal in place via fine muscle control in your foot you are going to get tired - use the weight of your leg instead. True of all vehicles. Also make liberal use of the cruise control. Note that holding speed is a bit trickier when it takes less accelerator movement, this is why there is some built-in play in the accelerator just like the steering wheel.

Or, any chance that Rivian is developing regenerative braking with the ability to turn off 1-pedal?

No chance at all, so if that's what you want then you can rule out Rivian.

Good info, thanks.

My wife will be the main driver. She weighs like 115, her legs are very light. She immediately noticed the difference between R1 and Mach-E in local driving (so no cruise).

Won't you need to wait until the R2 gets the software update for Launch Mode?

Ok after my glib response, here's what I'm thinking. There are two issues at hand here that you should consider.

1: When you turn off one-pedal driving, is it using brake by wire? That's what the R2 uses. No matter which level of regenerative braking you choose, the R2 is in control of both regeneration and braking. There is no direct connection between the brake pedal and the physical brakes. The car melds the braking and the regenerative braking and balances which it uses to maximize gegeration and only using the brakes as required to get the braking done that you want. There is a long list of details that I'm not able to articulate, but it's a very intentional choice by Rivian to minimize brake wear and giving you the braking you want.

2: When I drove the R2, it was set for the lowest level of regenerative braking. The only EV I had tried up to that point was a Lucid Air, which has a pretty aggressive one-pedal system. And when I came to a stop sign in the parking lot as we departed, I almost rolled through the sign because the pedal had such a light touch. I immediately switched it up to moderate, and then about 10 minutes later to the most aggressive regeneration. And that's where I kept it. My point being is that you should do a test drive. You might find the R2s lowest setting to be acceptable. It really is a light touch and lets you roll a pretty long way. Not much resistance to your foot. And you must use the brakes for sure to have the ability to stop where you want it to.
