We know this because the California automaker has, on the anniversary of its Cross Country Rally, sent a Roadster equipped with the prototype version of the 3.0 package from its Santana Row store in San Jose all the way down to the Santa Monica Pier. In all, the two-seater clocked the voyage at 340 miles and indicated another twenty left in the "tank."
According to an account of the trip on the Tesla website, the driver used cruise control to keep close to the speed limit and engaged the heater, at one point, for a 40-minute stretch. The total time is given as under six hours, with no mention of whether any stops were made for maintenance of the pilot.
While the electric car company still won't say when the package will be available – we asked – it seems like the wait will probably extend for a couple more months, at least. The prototype may have been ready for its maiden voyage, but the consumer version will get more development work using data derived from this early venturing forth.
