Elon Musk says that Tesla Motors will offer an upgrade to the Roadster, which is no longer in production, that will increase the range from around 240 miles (~385 km) to nearly 400 miles (~640 km) – Elon Musk on Twitter:
Roadster upgrade will enable non-stop travel from LA to SF — almost 400 mile range. Details tmrw. Merry Christmas!”
That’s close to the max range of most gasoline powered cars. There is still the big challenge to lower the very high cost of the battery packs but Tesla is clearly making good progress in EV technology.
Earlier in the week, Tesla also demonstrated a fast battery swap system for the Model S:

Update: Elon added this to his tweet above – Elon Musk on Twitter:
Should mention that a battery pack upgrade is not coming soon for the Model S, but it obviously *will* happen long-term.
