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.
Update: 2026-08-09
Tesla's Summer Update rollout has widened sharply since this article was published. Firmware 2026.26.1, released on 28 July 2026, had reached about 32% of the tracked fleet by 9 August according to NotATeslaApp's rollout tracker — up from the 15–20% that TeslaFi and Tessie data showed in the first days of the month. The original 2026.26 build, by contrast, sits at 0.8%, confirming that Tesla moved the entire wave onto the point release rather than running the two in parallel. European owners still waiting should expect 2026.26.1 directly, and can read the fleet percentage as a rough guide to how close their car is to the front of the queue.
Update: 2026-08-15
On 14 August 2026 Tesla moved the Summer Update wave again, this time to 2026.26.6.1. That supersedes this article's advice to expect 2026.26.1: the older point release peaked at around 31% of the tracked fleet and is no longer the build Tesla is pushing. The new version follows 2026.26.6 of 11 August and, according to Teslascope, adds only minor fixes and improvements on top of it — the Summer Update feature set described above is unchanged, so nothing in the per-model table needs revisiting. NotATeslaApp's tracker had it at about 6% of the fleet within a day of release, rising faster than any other build on the list, and going to Model S, Model 3, Model X and Model Y in both legacy and refreshed variants. European owners still waiting should now expect 2026.26.6.1 rather than 2026.26.1.
Update: 2026-08-19
On 11 August 2026 Tesla added two documented features to the Summer Update wave that were not in the original 2026.26 release notes, which corrects the note above. Estimated Range now folds battery ageing into the range figure on Model 3 and Model Y, so a higher-mileage car may show a lower — and more honest — number after updating. Speed Cameras on Route puts camera symbols along the navigation route and requires Premium Connectivity. Both arrived in 2026.26.6 on 11 August and carry over into 2026.26.6.1, which NotATeslaApp's tracker now puts at about 16% of the fleet — up from roughly 6% five days ago.
Update: 2026-08-22
By 22 August 2026 this wave had become the fleet's most-installed build. NotATeslaApp's tracker puts 2026.26.6.1 at 30.1% of tracked cars — 3,795 vehicles — which supersedes the roughly 16% quoted above three days ago, and TeslaFi's version table now ranks it first at 30.4%, ahead of the 2026.21.6 FSD branch on 26.9%. The more useful detail for the queue guidance above is that the wave is close to finished rather than still climbing: 21 installs were pending, and daily grants fell from 886 to 374. Distribution stays American-weighted — on Teslascope's smaller tracked sample the United States accounts for 51.85% of installs against 10% for the United Kingdom and 5.19% for Germany — so a European car still waiting is late in this wave rather than excluded from it.
Update: 2026-08-29
On 27 August 2026, NotATeslaApp detailed what the Summer Update changed in the web browser, which goes beyond the camera permission noted above. Bookmarks now sync across vehicles through a Tesla Profile, so saved sites follow you into a second car, a loaner or a rental. The default zoom level has increased, making text and images larger — though responsive sites such as X and YouTube may now load their mobile or tablet layouts as a result. Full-screen playback works on more streaming services, including HBO Max and Prime Video, which extends Tesla Theater beyond its native apps. The camera and microphone support turns out to be aimed at video calls, working with Microsoft Teams, Google Meet, Discord and Slack, with the interior camera available only while the car is parked and the feed cropped to the driver's seat. These browser features need the AMD Ryzen infotainment computer.
Update: 2026-09-19
More detail has emerged on what 2026.26 changed inside Automatic Navigation, which this article described only as extending suggestions from roads to destinations. According to Not a Tesla App, the release removed the fixed time windows the feature previously relied on — weekday mornings for work and afternoons through late evening for home — and replaced them with departure times learned from a driver's own history. The system now also tracks recurring trips beyond home and work, so a regular Saturday-morning or Tuesday-evening destination can be offered in its own right. Where its confidence is high enough it maps the route as soon as the driver sits down, with no input at all, and a new alternate-suggestions module sits under the main navigation card so a wrong guess can be swapped in one tap.
