It looks as if the rumors were true. The Tesla Model S has gotten a slight facelift in the latest refresh. The new Model S front end and headlights are more similar to the Model X now. The headlights are now full LED and are adaptive. There are also several new interior finish choices available online.
Some other new bits include the Tesla “bioweapon defense mode” cabin filtration system. This means 99.7 percent of particulate exhaust pollution, bacteria, and allergens are filtered out before air makes it to the cabin. Lastly the charger hops to 48-amps (up from 40-amps) to speed up fast charging.
