The 2022 model year (MY) BYD ATTO 3 was tested by Euro NCAP in 2024 and rated as ‘Not recommended’. 2025 MY vehicles are equipped with a Bosch Assisted driving system, and the software for 2022 MY vehicles, equipped with a Veoneer system has been improved. Both vehicles have been re-assessed. This assessment relates to the 2025 MY ATTO 3.
BYD’s appropriately named ‘Intelligent Cruise Control System’ accurately portrays system functionality. The promotional material and the handbook correctly indicate the limitations of the system capabilities. System status information is displayed but there is no head-up display. Driver monitoring has been improved, and the system now deactivates if the driver does not resume control within 30seconds of a warning being issued. However, detection of the driver’s hands on the wheel still lacks robustness. Overall, the system balances driver steering input with lane guidance, promoting co-operative driving.
The 2025 MY ATTO 3 uses camera inputs to detect speed limit signs. While the system is improved compared to the 2022 modelyear car, speed sign recognition remains inconsistent. There is no speed adaptation for upcoming road features such as curves and junctions. The 2025 MY ATTO 3 responds much better that the previous car in avoiding collisions in Euro NCAP’s ACC test scenarios. The driver is supported through the S-Bend, and the car is kept fully in lane at all of Euro NCAP’s test speeds, including the highest. A lane-change assist function is not provided. In case of an unresponsive driver, the ATTO 3 now automatically brings the car to a safe and controlled stop. If the radar or camera is blocked the car provides a warning but, in some cases, does not disengage.
The 2025 BYD ATTO 3 provides good levels of driver engagement and vehicle assistance. It is in the area of safety backup that the 2025 MY car far out-performs the 2022 MY, even after the earlier car has been updated. The 2025 MY car provides a high level of safety back-up and, overall, the system offers Good assistance in highway and interurban domains.
