CalmCar has unveiled ConnectOne, the first L4 Robotaxi developed on Horizon Robotics' Journey 6 (J6M) automotive-grade platform. This milestone highlights the maturity of China's autonomous driving technology and marks a step forward in large-scale commercialization.
Built on the SAIC Maxus MIFA 7 MPV, ConnectOne integrates CalmCar's proprietary L4 autonomous driving system with a dual-computing architecture. The main and redundant controllers deliver end-to-end autonomy through multi-sensor fusion, enabling 360° environment modeling, precise localization, and dynamic planning.
The vehicle delivers stable performance in complex urban scenarios such as unprotected turns, heavy traffic lane changes, and low-signal tunnels, while reducing controller costs by about 30% compared with conventional high-end systems.
By adopting an MPV platform, ConnectOne ensures generous cabin space, comfort, and accessibility—ideal for airport shuttles, family trips, and business travel. With both left- and right-hand drive versions available, it is positioned for deployment in global markets.
ConnectOne extends CalmCar’s multi-scenario L4 portfolio alongside Robobus and Robotruck, which are already operating in cities such as Chongqing, Chengdu, and Suzhou. From tourist shuttles and logistics to unmanned delivery and smart sanitation, CalmCar continues to broaden the real-world applications of autonomous mobility.
"Launching the first L4 robotaxi powered by the domestic J6M platform demonstrates CalmCar's leadership in high-level autonomy," said Xi Wang, CEO of CalmCar. "We will continue to refine our technology and services, expand collaboration with partners, and accelerate L4 deployments to build a smarter and greener mobility ecosystem."
