- The iX3’s exit-warning system uses side radar to briefly delay a door’s release if it detects an approaching cyclist.
- It debuts standard on the 2027 iX3 and will roll out to i3, X5 and 7 Series models.
- Berlin’s insurance association recorded 392 dooring crashes in 2024, about 8 percent of the city’s bicycle wrecks.
BMW now lets its exit-warning system briefly hold a door closed if a cyclist is coming up the bike lane. The Neue Klasse feature appears first on the new iX3 as standard kit, not as a buried option.
Side radar looks for bikes or cars before anyone pulls the handle. If something is approaching, the latch hesitates for a fraction of a second to keep the door from swinging into traffic.

How The Smart Door System Works
Traditional exit warnings flash a light or sound a chime. BMW’s system can go further and delay the latch when radar spots a cyclist or vehicle, turning a simple alert into a momentary block.
“Dooring” crashes are a known problem in bike-heavy cities, and they can cause serious injuries. That is why BMW is building this into its core safety package instead of treating it as a niche urban extra, using the same sensors that also support the iX3’s driving dynamics system.
The radar hardware also feeds a new reverse cross-traffic assist that looks for cyclists or cars at the sides, while Active Park Distance Control can now brake for flank obstacles. Emergency Brake Assistant can steer around hazards such as wildlife, tightening up low-speed safety in tight spaces.

Other BMW Models
The 2027 BMW iX3 is the first with this door hold, and the long-wheelbase i3 sedan, X5 and 7 Series models are in line to follow as Neue Klasse underpinnings spread.
BMW’s new central processor, nicknamed the “Superbrain of Automated Driving,” has far more computing power than the old setup and supports the brand’s growing list of steering and braking interventions. The iX3 already scores a five-star Euro NCAP rating under the stricter 2026 protocol, reflecting how much weight BMW now puts on active safety.
Real-world mileage will show whether a brief door hold actually cuts dooring crashes in crowded cities. Rivals now have to decide if they copy the physical door block or keep relying on chimes alone.
Motor1’s Take: This is important to urban cyclists and drivers who park on busy streets. It could cut simple collisions when a warning alone is easy to miss. Watch whether other brands adopt similar door holds. The data will tell if that split second at the latch changes behavior or just shifts the risk.
