Accelerator Pedal

[iBang]

For those of you who have driven multiple Rivian's have you noticed any difference in the accelerator pedal, specifically the amount you have to press it to get the truck to go? I always felt like I had to depress the pedal pretty far in order to get the truck going and often have leg fatigue as a result. I have had two loaner trucks before and have noticed a difference but I am currently in a loaner now and it just feels so much better. I don't drive with a heavy foot but I have to be much heavier and make the pedal travel further to accomplish the same thing in this loaner, where I am every so lightly depressing it to get it up to speed and feathering lightly to maintain that speed. I feel in my truck I have to make the pedal travel more up and down as well to maintain a consistent speed. I also notice the truck on OEM 20's gets really consistent and great efficiency, better than my truck when I had the OEM 21's on it. There is no variation to my day to day driving of where I go and when I go.

Has anyone else noticed a pedal that you have to press further down than say on other Rivian's?

I think all Rivians are like that. You have to push harder to get the speed you want. It's like a turbo gas engine that there is a slight lag/hesitation before it accelerates. I am not too fond of this. I also have Tesla Model S and it doesn't have this characteritic. The Tesla's pedal/acceleration response is silky smooth!

Except for the other two Rivians I’ve driven, where the pedal travel is minimal by comparison, including the loaner truck I’m driving right now.

Our R1S in All Purpose has better throttle response on acceleration than any ICE car we’ve had, from what I can recall: NA4, turbo4, turbo5, NA6, NA8 or supercharged8. Of the faults we can find with our Rivian, throttle response isn’t one of them. This is all subjective, though.

It would be interesting to do instrumented testing between a Rivian with good throttle response and a Rivian with bad throttle response with all things being equal: type (R1T or R1S), wheels/tires, surface, drive mode settings. Otherwise it’s tough to say objectively if the issue is hardware (maybe some throttles / TPS are off-spec?), tire & road surface traction differences, or perception.

I mention the traction because I think the Rivian will cut power in hard acceleration with low traction scenarios far more subtly than other cars I’ve driven. Some ICE cars I’ve driven would comically (borderline dangerously) cut power when accelerating from a stop and crossing low-traction paint stripes, as an example.

It would be interesting if Rivian displayed acceleration or regen on each wheel in the new gauges view as a pattern instead of a solid color when the traction was limiting what the vehicle permits. This could come in handy both on-road and off-road, I think.

My R1T has a quite a bit of dead-zone especially in reverse for some reason.

Haven't been given the opportunity to drive a loaner.

Co-worker has an R1S so hopefully I can test that out.

I've got the same issue and have talked to service about this. I've got an appointment already for my steering wheel making noises when moving into driver position. I have to depress the pedal 2 inches before the motors engage to move the R1S. The only way I can fix it so far is to sit really close to the steering wheel, so I use my leg to depress the accelerator and not my ankle. It's really cramped sitting like that, so service said they'd look into it. I think some of these issues need to be reported to service. I suggest that you set up a service ticket, you'd be luck to get an appointment sooner than two months, and see what service has to say.

I would like to see there will be a sport accelerator mapping on standard ride height.

This is honestly the one thing I miss coming from a Mach-E. Especially in Unbridle mode, the response is instant and super easy to get up to speed. I'm getting used to the response of the Rivian and can deal with it, just wish I didn't have to press as firmly. I have dual standard so that may be part of it as well.

I have a bit of arthritis in my right ankle so I end up using cruise control more than I prefer to on highways to give my ankle a break. To be fair, I noticed it when I did a demo drive and leased one anyway, and there's way more leg room than the Mach-E, so there are tradeoffs.

Many years ago I had a friend who worked as a technician at Chuck-E-Cheese. We'd rebuild our carburetors using springs from Skeeball machines. Made pressing the gas pedal like stepping on a brick, but sure saved gas... LOL. Maybe same concept here? ?
