I have one of the first Model 3's and I had to replace tires at 30K. I have had quite a few off road trucks and jeeps with 35's and 37's. They all seem to go pretty quick as they tend to be soft rubber. The weight of this beast should eat through tires pretty quick.
Elon said it is a 2 person ATV. That is not a 2 person. The link that stubby posted looks like those on get and 35 mile range. I would be out of juice in less than an hour.
So, It has one and it's electric. If you watch the reveal video, when the guy rides the quad up you can see it disappearing in-between the cab and the bed of the truck. I hope you can partially close it to where ever you want.
disappointed with tow rating. I think my 24' enclosed trailer will be at it's limits. I don't like to tow at max limits. I had a chevy dually diesel. I could tow pretty much anything I could hook up. never had to think about it. Not the case with Cybertruck.....
