Tesla's 2026 Summer Update finally has a version number attached to it, and it is on the fleet. The release ships as firmware 2026.26, first pushed on 26 July 2026, and Tesla has already moved the wave onto a 2026.26.1 point release. TeslAnt covered the feature set when Tesla first revealed it; this is what actually landed, and which cars get which parts of it.
Navigation gets the biggest practical win
Preferred Routes is the headline for anyone who drives the same roads every day. Navigation now prioritises routes you have already taken instead of always defaulting to the algorithm's fastest suggestion, and it needs Online Routing switched on to work. Automatic Navigation extends the same idea from roads to destinations, offering places you visit regularly rather than only Home, Work and calendar entries.
Two smaller navigation additions were not in Tesla's original reveal:
- Supercharger search by name — you can now find a specific Supercharger by name when searching for a destination instead of hunting for it on the map.
- Set Arrival Energy — pick the charge level you want on arrival at a destination from the mobile app.
What each car actually gets
Not every feature reaches every car. The split follows the infotainment silicon and the model generation.
| Feature | Models |
|---|---|
| Preferred Routes, Automatic Navigation, Supercharger search, Set Arrival Energy | S, 3, X, Y, Cybertruck |
| "Hey Grok" and Grok commands | New S, 3, New X, Y, Cybertruck (AMD) |
| Caraoke with scoring, Web Browser camera and microphone | New S, 3, New X, Y, Cybertruck (AMD) |
| Driving Visualization zoom preference | S, 3, X, Y, Cybertruck (Intel and AMD) |
| Traction Control Modes (Auto, Slippery Surface, Stuck Assist) | Model 3 only |
| Welcome Animation | New Model 3, New Model Y |
| Custom Wraps, Apple Music queueing, rear-display lock | S, 3, X, Y, Cybertruck |
The Grok-dependent features need the AMD Ryzen infotainment computer, which leaves out earlier Intel-based Model S and Model X cars — the same dividing line that has governed Tesla's software features since the Ryzen switch. Traction Control Modes is a Model 3 exclusive in this release, and the refreshed Model 3 and Model Y are the only cars getting the new welcome animation.
Two undocumented changes also turned up: the Model Y Performance rear spoiler now appears in the driving visualisation, and the vehicle renderings have more accurate lighting.
The new browser permission is worth a thought
Web Browser can now use the interior camera and the cabin microphone, with the camera available only while the car is parked. This is the first time Tesla has given browser-based web pages access to in-cabin sensors, and it is the one item in this release owners may want to consider before turning it on.
Rollout in Europe
As with every seasonal release, 2026.26 arrives as a staged over-the-air rollout rather than a single-day switch, widening as Tesla watches the telemetry come back. Grok availability in particular varies by market, and several features depend on a paired phone or an active streaming subscription.
European owners should check the software tab in the mobile app to see when the update is queued for their car, and should expect to receive 2026.26.1 rather than the original build — Tesla has already rolled the wave onto the point release, which folds in security fixes alongside the feature set.
