how many miles can a tesla
(Alexander Nie / Flickr) Last week, Elon Musk announced that the Tesla Roadster would be receiving a retrofit upgrade that bumps its range to around 350 miles. Under ideal driving conditions, Musk claimed, the new Roadster can go as far as 400 miles without stopping to recharge. Naturally, a lot of Tesla watchers are probably wondering when the Model S (which is significantly more affordable but still out of reach of most consumers) will benefit from this technology.
