Downloaded via the car’s on-board data connection, it introduces two new features to address range anxiety and help drivers plan routes more effectively.

Trip Planner takes care of forward-planning, using a database of live charging point information to plan a route via the most convenient and readily-available units, and it messages the car’s smartphone app once charging is complete.

Range Assurance gauges the remaining battery life based on topography, weather and wind speed for improved accuracy and warns the driver if they risk running out of power.

The software update also builds on Tesla’s Autopilot hardware, introducing Automatic Emergency Braking, Blind Spot Warnings and Side Collision Warnings on top of the first features added with the 2015 Model Year cars. The Active Cruise Control function has also been refined, Tesla said.

Minor upgrades to sound quality and radio tuning, plus a Valet mode which limits the vehicle’s speed, locks the glovebox and ‘frunk’ and hides personal data in the infotainment system, complete the new features in the software.
