Using brakes to control relative power delivery to your wheels can be much better than a relatively dumb locking or limited slip differential, for one excellent reason. It can be adjusted in fractions of a second, much like antilock brakes. It's all about finesse. This statement from the...

I wonder why (just kidding!) Rivian didn't include data on vampire drain? That definitely falls into "SOH" of the battery. Of course, I would promise not to compare VD notes with others on this forum, because.. It wouldn't be polite!!

I totally agree with you, but using that crude servo to assist is dead easy, modulation is much more complex. There are similar systems, but they don't accomplish much to get a full one pedal system designed and into production. Just in tooling alone, this would be a monstrous cost.. Customers...

Before even spending energy on pro's and con's, it would save wasted time just pondering how it might be made possible. ICE brakes all require mechanical input to a hydraulic system, and obviously some mechanism to do this (electric servo power?) is going to require a great deal of effort in...

Welcome to the forum OP. So it seems you had all kinds of details that would have A) helped a lot of the forum people to understand your problem, and B) empower them to actually help you, rather than get frustrated. When my Gen 2 had the dreaded vampire drain, and I was concerned about this, I...

I haven't towed anything that light, so I can see why someone might not want the AWD default. But when I tow my 16 foot trailer, with up to 9,000 pounds of gross weight, I can appreciate the already mentioned stability, but also the regen braking. It's obvious that towing this kind of weight...

I found a way due to needing a better way to get what I need efficiently, I keep all my manuals on my Macbook and iPhone - in PDF format. Because PDF's are searchable, and I can carry everything I need everywhere!

Swampnut, I drove onto the ferry, and intended to move the side mirrors inward. That requires using the same menu that opens the tailgate.. Well I hit the wrong button, and if it were not for the ferry staffer I would have dropped it onto the hood of the vehicle he was positioning behind me...

OP, you stated that it was a brand new crossing, so did you stop and get photos of the fallen barrier? It might have had some kind of issue causing it to abruptly drop.. Either way, it should be reported, seems to be a safety issue to me.

When inventors talk about their new tech, we can expect them to cite maximum performance aspects, and then walk back such specs as charging time - which will likely not reflect real world performance. It's easy to test charging rate in a lab, but actual charging on a 92F day after 200 miles...

I got my security fasteners here: https://ogsecure.co.uk/collections/security-nuts . I chose the penta nut style, figuring it would be hardest to defeat with standard tools.

It's totally legit to use an appropriate extension on an EV charger, IF the following are true: 1) The electrical conductors are safe for the current flow 2) The cross sectional area and quality of the contact surfaces in both male/female plug are safe for the current flow I have been using a...

Thanks for the physics lesson, as a 46 year aerospace design engineer I know how to calculate stress! That said, who would put rigid tiles directly on a wonky surface and then be surprised that they crack? 😂 The 'total weight' needed clarification, thanks for that. It translated nicely into...

This is wrong in this context, because weight distribution is precisely what matters in it's effect on specific materials placed between the vehicle and garage floor. The floor material needs to support 48 psi, the more or less flexible tile needs to support that precise same pressure. If you...

Here's some load data: Vehicle weight = 7,200 pounds, so 1,800 pounds on each tire. Since the tires are inflated to 48 psi, that gives an area of load of 48 pounds per square inch, which gives a tire contact area of 37.5 square inches. So the pressure on those tiles is significant, but not huge...

Do any of you know if the proximity can be adjusted? As in from whatever the default is to minus 10 feet? If it's adjustable I'd like it to lock/unlock from a pretty close distance...

Hmmm, it would seem that having a rule based on 'amount of cost for repair' would incentivize the opposite of a 'new quality' job. Especially when damage happens outside of the manufacturers custody of the vehicle, because where is the delivery services incentive to: A) Inform the manufacturer...

I've been avoiding the .46 update because I finally had my vampire drain down very close to zero, but had seen others have the VD increasing... So am I to understand that if I update to .46, but turn the proximity setting off, I can expect the VD to stay as it is, very low? Thanks all!

I haven't tried this in the frunk, because I didn't intend to put it there. But for fit under the PTC, this is the best I could find, and it's 41 quarts: So it's close to the volume of the two smaller ones above, but definitely hefty.

I will add another dimension, in general rusting rotors on EV's varies a lot due to type of driver usage. If you are a driver who uses max regen, then the foot brake gets used extremely rarely.. The opposite rubs the pads/rotors much more per mile. If even a very thin layer of rust can remain on...
