Probably... 

In Tesla Roadster travels 313 miles on single charge

...Down hill, with a tail wind. Most likely on cruise control at a walking pace. Wind resistance goes up as the square of the speed.

The other alternative is that they stowed it in a truck (Lorrie) for the trip, and drove it for the last 5 miles.

Me? My nice SUV gets about 350+ miles on a tank of gas going over 70mph down I-5 in the central valley (of California), and it hauls a bunch of stuff while I'm doing it and the air conditioner is just fine thank you.
