BMW Becomes First German Carmaker to Receive Global Approval for Hands-Off Motorway Assistant

BMW has made history as the first German manufacturer to gain international approval for its next-generation driver assistance systems under the new UN “DCAS” (Driver Control Assistance Systems) regulation. The milestone allows the brand to roll out its Motorway Assistant technology across more European countries, beginning with the all-electric BMW iX3.

The Motorway Assistant represents a major leap forward in Level 2 semi-autonomous driving, allowing drivers to rest their hands in their laps while maintaining full control and situational awareness. At speeds of up to 130 km/h, the system handles lane-keeping and can even perform automatic lane changes – confirmed by nothing more than a glance in the wing mirror.

With active BMW Maps route guidance, the system can now anticipate motorway exits and junctions, suggesting timely lane changes that the driver approves visually. Unlike earlier systems, the Motorway Assistant continues to function smoothly through complex junctions and right up to the end of slip roads, offering a more natural and uninterrupted experience.

The DCAS certification eliminates the need for the individual exemptions previously required by the German Federal Motor Transport Authority, paving the way for BMW to expand these features across Europe and other ECE-compliant markets.

Dr. Mihiar Ayoubi, Senior Vice President of Driving Experience Development at BMW, said:

“The safety-oriented DCAS regulation ensures we can launch our Motorway Assistant with hands-off function in many more countries. Our systems create a perfect interplay between rule-based algorithms and artificial intelligence. The driver remains involved, our systems are controllable at all times, and their behaviour is reproducible.”

Expanding to City Driving

BMW is also preparing to bring its City Assistant features to the iX3, capable of stopping at red lights and setting off again automatically. Additional functions for more complex urban environments will be added later through over-the-air software updates.

Introducing BMW Symbiotic Drive

This new approval coincides with BMW’s unveiling of BMW Symbiotic Drive – the brand’s next-generation approach to human-machine interaction. Unlike conventional systems that take over entirely, Symbiotic Drive blends driver and vehicle input seamlessly. The driver can gently intervene in steering or braking without deactivating assistance, creating a more natural and confidence-inspiring partnership between human and machine.

The iX3 will be the world’s first vehicle to feature Symbiotic Brakes, a technology backed by over two dozen BMW Group patent applications.

Recognition and Future Development

The current Motorway Assistant has already earned the Tech Award for Comfort Assistance Systems from auto motor und sport, reflecting BMW’s leadership in user-friendly, safety-focused automation.

As the Neue Klasse generation of vehicles arrives, BMW plans to extend this symbiotic philosophy to all aspects of driving – combining intelligent assistance with driver intuition.

BMW iX3 50 xDrive (WLTP figures):
Energy consumption combined: 17.9–15.1 kWh/100 km
CO₂ emissions: 0 g/km
Electric range: 679–805 km
