Also, Tesla is rumored to be offering Aero wheels, which add 20 miles to the 300 mile range. They should add more range as a percentage at higher speeds.

Tesla has published that information for the roadster here:

The roadster gets about 240 miles at 55mph, and about 150 miles at 80mph. Model S is more aerodynamic so it should do better, air drag doubles from 55 to 80 on roadster.

Electrics are different than gas cars. As a gas car goes faster, it uses more power, but its specific fuel consumption (gal/hp) gets better since gas engines are more efficient at higher loads. That makes the drop off more gradual as you go faster. Gas cars get much worse in the city, especially stop and go. The EPA city cycle has lots of stop and go with very low acceleration rates, so I expect Tesla to at least make their number for EPA range.
