Lidar will probably be added to the manufacturing automotive sooner or later, and Mercedes says SAE Stage 3 self-driving will probably be obtainable, although that will probably be topic to native laws. A rear seat little one detector system will probably be obtainable from the beginning.

A manufacturing model of the Imaginative and prescient CLA will debut in late 2024 because the CLA-Class four-door coupe, most likely as a 2025 mannequin. Prototypes have been noticed testing. Search for an official reveal of the manufacturing automotive subsequent yr, and pricing and full specs ought to observe nearer to launch.
