Tesla’s 2025.20.3 over-the-air update brings two standout features: the much-anticipated Grok AI personas and a smart navigation tip to save energy. The firmware reveals a dozen new Grok personalities—including Language Tutor, Argumentative, Therapist, Romantic, Sexy, and the classic “Unhinged” mode—complete with icons, suggesting the AI assistant is nearly ready for public rollout, at least on AMD-based Teslas . Alongside this, a new energy-saving prompt now appears in the Energy app during navigation, advising drivers to reduce speed based on real-world fleet data—e.g., “This route is typically driven at 66 mph. Slow down by 5 mph to save 1% battery for the rest of this trip” . Both features signal a shift toward more intelligent, data-driven in-car experiences for Tesla owners.
