The Lucid Air is officially making its debut September 9, but today they let us have an idea what kind of range it will get: 517 miles. Impressive, right? I think so. And I also think that Lucid needed a nice dramatic number like this. It's a new luxury brand with zero history and zero cache -- that's something it has to build. You can't build anything on a mediocre product, so this car is extremely important for the company and it has to have a technological edge on the competition. Oh, it should be noted here that the range number was the result of testing by FEV North America using the EPA's Multi-cycle Test Procedure (SAE J1634 Oct 2012 Standard). Now, we don't know how big the battery is, so we can't say if it is actually more efficient than the latest Model S, but I don't know if that truly matters as much as the headline number.
