Tesla is gearing up to announce a new product Tuesday afternoon.

CEO Elon Musk tweeted that the product announcement would come at noon PT (3 p.m. ET). We don't know for certain, but it could be an announcement relating to when Tesla will roll out Autopilot 2.0 and the new features that will come with the upgrade.

All Tesla vehicles built since 2014 come with Autopilot, which offers safety features like automatic braking, lane switching, and blind-spot warnings. A software upgrade released in January added new features like the ability to self-park in the perpendicular position.

Tesla could also be gearing up to announce a new 100 kWh battery in the Model S and the Model X. The Dutch blog Kenteken.TV reported in August that RDW, the Dutch authority responsible for vehicle registrations, had approved a 100 kWh battery option for both Tesla cars.

The new battery option could extend the range of the Model S to as much as 380 miles — a pretty major bump from the 270-mile range offered by the Tesla's most powerful Model S, the P90D.
