This looks like it can handle pretty much any hostile environment, like volcanoes! So it's called VulcanXplorer!
8 nano constructors and 2 plasma devastators mean you can heal anyone anywhere around you and also spread some devastation.
I've been playing this for over a week now. It's very tanky, takes lots of damage and I've never been immobilized by losing wheels :)
The inside is filled with aerorods, so it's not as heavy as it looks.
In the video you can see the benefits of using a hover on a car. It never spins out. I climb up and down steep hills repeatedly. The hover prevents me from flipping when going off a cliff and landing upside down. I love it!
