Changes to the front of Tesla's all-electric Model S are more than cosmetic.

Tesla's Web site says Model S now features full LED adaptive headlamps and a medical-grade HEPA air-filtration system.

"Fourteen three-position dynamic turning lights improve visibility at night, especially on winding roads."

The HEPA air-filtration system "removes [from cabin air] at least 99.97% of particulate exhaust pollution and effectively all allergens, bacteria and other contaminants."

Tesla CEO Elon Musk has said 53,000 people die every year from auto emissions.

"The bioweapon defense mode creates positive pressure inside the cabin to protect occupants," according to Tesla Motors.

And Model S now comes standard with Autopilot, Autosteer and Autopark.

The new "Summon" feature lets you call your car from your phone "so it comes and greets you at your front door in the morning." 

Features are enabled with software updates.
