Tows 5000 pounds
Standard AWD
Higher ground clearance (speculating)
Also, Tesla didn't start the re-definition of SUV they're just saddled with the term like everyone else.
SUV just means having a higher ride height than a normal car.
There are plenty of SUVs with no 4WD, woeful towing capacity and 3 doors.
There are snarkier ways, like a car is a vehicle where 75% of the seats are empty almost all the time, whereas a SUV is a vehicle where 85% of the seats are empty almost all the time, so the cutoff is around 80% usually empty.
Slightly more seriously a SUV can be defined as a car that has a towing rating approved by the mfgr. I've never owned a car where the mfgr approves any towing weight at all, and I've never heard of a SUV that can't at least tow some minimal weight.
The lines are ambiguous. "SUVs" nowadays range from minivans that don't look like minivans (crossovers) like the Ford Edge to actual SUVs like the Jeep Grand Cherokee. My personal definition is if you can take it off road on a trail with no mods and there is no bed, it's definitely an SUV. If you can't realistically take it on a trail, it's a crossover.
