10% charge in 6km of tow charging is impressive. I also didn't realize they're using the 135 kWh battery for the rally and not the big battery.

Yeah. I guess the weight is one of the factors. The 135kwh version. Already weighs 5886lbs. Not sure how much more weight the 180kwh will add...

That's probably the reason. It also helps that the organizers designed the course for the R1T to compete.

So the tow charging works by adding drag to the tow vehicle, right? If you know that your destination will have charging, and you want max fuel economy from your tow vehicle, can you turn off the tow charging? For lack of a better term, can you put the Rivian in "neutral" so to speak so it is spinning freely and not adding as much drag to the tow vehicle?

Conservation of energy and all that...

I have to think so. I doubt tow charging would be the default. It's probably a special mode you have to put the truck in.

From the way they describe it in the video there's no way you can do this safely on a public road

I would think "yes".

Either way, you'll have to set the vehicle into a special mode, since you'll need to put it into Neutral to tow it, so it makes sense that there's a separate setting for whether to tow-charge or not.

Eventually we will be able to charge everywhere
But from what I've seen and heard RV places are catching on to Electric Vehicles charging and they aren't happy about it
Yes it would be sweet if you could turn on and off the tow charging
So like going downhill use the Rivian as a break
So as to use wasted energy to charge
But that is probably not going to happen
A lot of work for only a few customers
But would be incredible to use the Rivian as a Engine Brake for my Rig considering I go back and forth Phoenix to Denver a lot
