Tesla CEO Musk unveils Model S upgrades

3 announcements out of Tesla

Tesla Motors unveiled upgrades for its Model S electric car line on Friday.

Tesla CEO Elon Musk addressed the developments in a conference call. Tesla shares were trading about 3 percent higher into the announcement and initially lost ground after Musk's remarks, only to climb again and close near pre-call levels.

A battery upgrade from 85 to 90 kWh is available to Model S owners for $3,000. The new battery would provide up to 15 miles of additional range, Musk said.

Tesla will offer a single motor version of the 70 kWh Model S for $5,000 less than the the dual motor version, Musk added. That model will cost $70,000.

The company will also add a "ludicrous" mode option for the car, which decreases the amount of time it takes to go from zero to 60 mph.

Musk also detailed developments in the release of Tesla's newer vehicles. Deliveries for the Model X will start in about two months, with Model 3 deliveries are slated for more than two years out.

Tesla delivered 11,507 Model S cars in the second quarter, a 52 percent increase from the previous year, the company said earlier this month. Tesla has repeatedly made efforts to increase driving range and affordability for the vehicles.
