2023 M4 Convertible Safety

There is no safety review of the BMW M4 Convertible available. Neither the NHTSA nor the IIHS has had the opportunity to test the 4 Series range, including the M4. Since it's based on the 3 Series, it is worth looking at the sedan's ratings. It scored five out of five stars in every category from the NHTSA, while the IIHS gave the 2022 3 Series a Top Safety Pick award when equipped with adaptive headlights.
