Apologize for my fat fingers and bad eyesight! Really destroyed your name!
I think several members of this group have different views on regen beyond just braking.
Like I said previously, I just want the ability to configure it to off when it’s a Toad.
But frankly, I don’t buy that regen braking would safely stop BOTH my 50k RV and the R1T. Trust me, I’ve seen RV drivers accidentally pull their TOADS without knowing that theTOAD’s wheels were locked.
I would think if it was all that easy, why put mechanical brakes on the R1T in the first place? What are the impacts to ABS features?
I’ll love using the R1T’s regen braking when I’m in it driving.
I didn't say regen would stop your rig, but it would slow it down, or maintain speed, even on the steepest hills. The motors can produce a significant force at speed and could easily slow or maintain the speed of your rig down a slope while throwing a lot of energy into the batteries. As you slow down, that force diminishes and you need the mechanical brakes to maintain a similar force. You could have an EV without mechanical brakes. But as the regen braking force is diminished, you would need to apply a reverse field to the motors which would use energy where the mechanical brakes would not. Also, the mechanical brakes are a fail safe.

FYI: Episode 5 of “The Long Way Up” shows R1T VIN#1 with depleted battery in South America being towed by a semi-truck to regen. It took a fairly short amount of time give it enough power.

I saw that, they claimed half the range in 1 hour of towing... Not sure what pack they were using though since in the begining they mentioned ~200miles range, but I also saw that they got ~315 later on the trip.
