Aboutaster 1.2.0.
firefly offers an intelligent driving experience with intuitive and seamless interactions. As firefly's central operating system, aster 1.2.0. works as the heart of all intelligent functions. “With aster 1.2.0, we’re advancing firefly’s software-defined approach in ways users feel every day. Over-The-Air updates keep the car improving continuously, while our AI companion Lumo makes interactions more natural and personal. At the same time, new safety and convenience features turn everyday driving into a calmer, more confident experience”, says Peter Seitz, Head of Product firefly. The update delivers high-performance artificial intelligence (AI) capabilities, seamless connectivity, and smart experiences. With advanced computing, it enhances safety, entertainment, and interaction between driver and vehicle.
Enhanced safety with assisted driving
The update introduces the brand-new Rear Collision Warning (RCW), alerting drivers of potential hazards from behind when the vehicle is stationary or moving forward. In addition, the system now reacts intelligently to heavy rain, automatically suspending assisted driving functions like Adaptive Cruise Control (ACC) and Pilot Assist for safety. Parking is now smoother and more efficient, while alert sounds have been fine-tuned to provide clearer, more appropriate reminders. In addition, the driver monitoring system has been enhanced to reduce false alarms caused by factors like seating position or driver height.
More convenience in everyday driving
aster 1.2.0 enhances the driving experience, making it even more comfortable and safe. The updated account memory now links individual driving preferences such as regenerative braking or one-pedal mode to the user profile, ensuring truly personalized journeys. Smart reminders prevent common mishaps, such as leaving the car unlocked if the connections drops when using the Bluetooth key, or misplacing objects on the wireless charging pad. Furthermore, wireless Apple CarPlay now provides effortless access to calls, music, and apps.
Introducing Lumo visual feedback
firefly's own in-car AI assistant, Lumo, will appear in the form of a yellow circle in the center display, activated with a simple “Hey Lumo”.
When using lumo voice commands for functions like navigation, air conditioning, window adjustment, pet mode, and more, the center display will now show related graphic feedback of lumo, delivering a more vivid interaction for users.
More comfort, playfulness and personalization for the cockpit
With aster 1.2.0, the cockpit becomes more personalized and engaging. For example, a new energy consumption theme allows drivers to track efficiency in real time with dynamic graphics. The trip summary now includes additional insights such as average consumption and speed. Users can also choose how the battery level is displayed, either as percentage or remaining range. Interactive animations such as the pet mode, playful feedback, and sound further enhance the user experience, making every interaction lively and enjoyable. For easy operation, the Quick Control Panel now includes more functions such as locking all doors and comfort scenarios (warm/cool).
Map and driving
Navigation now surfaces distance to destination and estimated time of arrival on both the center display and the instrument cluster, plus quick controls to mute prompts or end guidance for distraction-free driving. Multi-stop trips are easier to follow thanks to expandable waypoint views that show per-leg details and the remaining range to reach each stop.
Over-the-air updates for lasting performance and safety
firefly can be updated Over-The-Air (OTA) with software and firmware updates at any time, which continuously optimizes the experience for users. The updates upgrade all linked functions in the firefly system architecture, from assistance systems and navigation to seat heating and battery management. This ensures long-term performance, security, and reliability.
