Tesla continually improves its electric vehicles with over-the-air software updates that include enhancements to Autopilot, legacy “Enhanced Autopilot”, and Full Self-Driving (FSD) features in the future.
Note that Tesla recently completely updated their Autopilot options to simplify the lineup across its EVs. Enhanced Autopilot is no longer offered and instead, autonomous driving features have been folded into the Full Self-Driving option.
How Often Do Tesla Software Updates Occur?
Tesla Motors continually rolls out firmware updates to its electric cars, including the Tesla Model 3, Model S and X, probably even the Semi and upcoming Roadster ;). They typically test new features on a smaller set of vehicles first (e.g. 1,000), including Elon Musk’s own car, to ensure there are no issues ‘in the wild’ before rolling firmware updates out to the broader fleet.
How often your Tesla’s Autopilot is updated depends on your patch cycle. Each Tesla vehicle typically has a 30 to 60 day patch cycle, which means that you may not get every incremental update. This ensures the electric vehicle fleet is relatively heterogeneous and not prone to single-bug failures.
It’s probably also helpful to have a strong Wi-Fi signal since the updates can be large. The good news is that your Tesla mobile app will now alert you to updates and allow you to apply them remotely!
What Do the Tesla Software Version Numbers Mean?
Tesla software updates typically look something like this: 2019.40.50.5, where the numbers generally mean:
- 2019 – year
- 40 – week of software build
- 50 – version / revision
- 5 – bug patch number
When you have an update available, the Tesla app will now show you the version number ready to be installed.
