A Tesla was just driven 388 miles on one charge in Holland. The car averaged 24 mph or what you could expect to do in New York City. But the European Tesla distance record is not a world record.
Apparently, the world record for Tesla range is 423 miles set by two Floridians.
Used normally, the Tesla Model S can be expected to go 265 miles between charges. And that is the key to its incredible success.
