One of the things that sets a Tesla apart from many other cars is over-the-air updates (OTA). Instead of a new feature requiring a new car model or a workshop visit, the software can be updated wirelessly — just like on your phone. That means the car can evolve after you've bought it.
What is an OTA update?
OTA means "over-the-air": updates are downloaded wirelessly, typically via Wi-Fi at home. They can range from minor bug fixes and improvements to entirely new features in the interface, charging, maps and driver assistance. What a specific update contains varies from version to version and by market.
What can updates add?
- New or improved features in the screen interface.
- Improvements to charging, efficiency and range display.
- Entertainment, apps and small refinements.
- Improvements to driver assistance (depends on package and market) — see Autopilot vs FSD.
How to install
When an update is ready for your car, you're notified on the screen and in the Tesla app. You can typically choose to install immediately or schedule it for, say, overnight. For the larger updates a Wi-Fi connection is recommended, and the car must be stationary during installation.
Good to know
Updates roll out in waves, so two cars don't necessarily get the same version at the same time. It's completely normal to wait a little for a new version. Always read the feature notes that come with the update.
Why it matters when buying
The OTA model is part of the value of a Tesla: the car can get better over time with no extra hassle. It also makes used Teslas interesting, as they typically run the latest software. If you're new, start with the beginner guide, and look up terms in the glossary.
