Musk also announced that the Model S line will be getting an automatic steering mode, which he calls "autopilot," in three to four months.

The Model S lineup currently offers traveling ranges between 208 and 270 miles, based on the EPA's mileage standard. Tesla has also updated its original Roadster with a huge range bump thanks to some new hardware, and it also unveiled a "Torque Sleep" mode that made dual-motor Model S cars more efficient. The electric car company has also aggressively rolled out its Supercharger stations across the US, Europe, and China. Musk says it plans to cover all of North America and Europe with charging stations by the end of the year, as well as most populous areas in China (don't bet on seeing anything in the Gobi desert).
