Tesla Software Update 2025.8: Undocumented Innovations in Detail

Tesla's Software Update 2025.8 brings numerous small but fine improvements that were not included in the official release notes. From more precise trip meters to map tweaks to a revamped Rainbow Road – we show you what has really changed.

More Precise Trips & New kWh Value

More Decimal Places: "Current Drive" and "Since Last Charge" now show miles and kWh with one decimal place.
kWh for Current Drive: In addition to driving time, you now see the energy consumed – perfect for efficiency fans.

Map Upgrade with Fresh Icons

Round symbols with a white border make Superchargers, Destination Chargers, and POIs stand out more clearly from the map background.
Destination navigation stops voice output immediately as soon as you end the route.

Destination Chargers at a Glance

When you activate Points of Interest, the Tesla-Destination Chargers now appear. Convenient for hotel or restaurant stops along the way.

Bluetooth & Audio – Smarter Connections

The Bluetooth tile uses free space to jump directly to other streaming sources (Spotify, Apple Music, etc.).
Tip: If you play music via your phone, the display now suggests the integrated Tesla-apps.

Rainbow Road 2.0

Rainbow path completely replaces the blue autopilot trail – including chevrons when decelerating.
Four taps on the right drive lever start the Easter Egg; you can now stop the music using the volume knob.

Visual Fine-Tuning on Intel MCU

Transparency effects have been extended for older Intel vehicles. Notes: No blur, so readability may be slightly reduced depending on the map background.

Revised Info Graphics

New “Phone Key missing” image with a modern look.
Additional tooltips explain functions contextually.

Service Mode – nine new diagnostic tools

HVAC Panel checks actuators, HEPA, and blower (Cybertruck).
Battery SOH now directly under “Service” without service mode login.
Rear Window Defrost routine simplified (all S3XY 2021+).
Seat panel shows whether Cabin Radar or seat sensor is active.
Brake & steering: Gateway parameters (hardware type, color) adjustable.
Media automatically switches to Bluetooth in service mode to protect customer accounts.
New Charge Port Reset under Charging for CP-ECU.
Noise Recording moved to the tools tab (Cybertruck).
Coolant panel shows status of a purge procedure (Cybertruck).

Conclusion – small update, big added value

Update 2025.8 once again shows how Tesla continuously improves comfort and diagnostic capability. Although the Spring Update 2025.14 is already being distributed, 2025.8 is worthwhile for everyone still waiting: more accuracy in trips, better map readability, and noticeable usability tweaks.

Pro Tip: After installation, check the new trip meter values and activate Rainbow Road – you'll notice the difference immediately.
