Summary
Tesla increases range, stock near all-time high, patent for Cybercab revealed, FSD tests ongoing, Grok rejects Tesla's robotaxi.
In the 39th calendar week of 2025, Tesla had numerous news: a range increase for existing models, the stock nearing its all-time high, a patent for the Cybercab published, new FSD tests in Europe, and a curious rejection by the AI assistant Grok. Here are the details.
More Range for Everyone?
Tesla has apparently rolled out an update for the battery management software that slightly increases the usable capacity of older vehicles. Owners report up to 5% more range. This could be part of Tesla's strategy to increase customer satisfaction. More details on possible savings can be found in the article Tesla: 2025 threatens second year without growth.
Stock Near Record
The Tesla stock is trading near its historical high. Analysts attribute this to strong delivery numbers and positive signals from the autonomous driving sector. An IPO of the robotaxi business could be the next catalyst.
Cybercab Patent
A newly published patent reveals details of the planned Cybercab robotaxi. It describes a modular seating system and improved sensor configurations. This underscores Tesla's focus on autonomous driving. More on this topic can be found under Tesla FSD V14: The Second Largest FSD Update Ever.
FSD Tests in Europe
First European customers are testing the Full Self-Driving (Supervised) Beta. Feedback is mixed: while highway performance is convincing, there are still weaknesses in complex city traffic situations. EU approval remains a decisive factor.

[NOTE] Hardware Comparison: While US vehicles mostly use HW4 (AI4), many European Teslas are still equipped with HW3 (FSD Computer 3.0). Table shows differences:
| Feature | HW3 (FSD Computer 3.0) | HW4 (AI4) |
|---|
| Computing power | 144 TOPS | 720 TOPS |
| Cameras | 2x 1.3 MP | 4x 1.3 MP |
| Radar/Vision | Pure Vision | Pure Vision+improved |
| Europe availability | Yes, widespread | No, not yet approved |
[IMPORTANT] HW4 approval in Europe is pending. Without it, many functions cannot be fully utilized.
Grok Says No
Tesla's own AI assistant Grok was asked whether the Cybercab is a good idea. The answer: No, citing regulatory hurdles and lack of infrastructure. Elon Musk commented on this with a wink on Twitter.
