The passenger compartment of the 2 Series Coupé remained stable in the frontal offset test. Dummy numbers showed good protection of the knees and femurs of both the driver and passenger. BMW showed that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions. Analysis of the deceleration of the impact trolley during the test, and analysis of the deformable barrier after the test, revealed that the 2 Series Coupé would be an aggressive impact partner in a frontal collision. In the full-width rigid barrier test, good or adequate protection was provided to all critical body areas, for both the driver and rear passenger. In the side barrier test, protection of all critical body areas was good and the car scored maximum points in this part of the assessment. In the more severe side pole impact, protection of all critical body areas was good or adequate. Control of excursion (the extent to which a body is thrown to the other side of the vehicle when it is hit from the far side) was found to be marginal. The 2 Series Coupé does not have a countermeasure, such as a centre airbag, to mitigate against occupant-to-occupant injuries in such impacts. Tests on the front seats and head restraints demonstrated good protection against whiplash injuries in the event of a rear-end collision. A geometric analysis of the rear seats also indicated good whiplash protection. The 2 Series Coupé has an advanced eCall system which alerts the emergency services in the event of a crash, but does not have a system to prevent secondary impacts after the car has been in a collision.

In the side barrier impact, measurements of accelerations in the head of the 10-year dummy indicated weak protection. Otherwise, protection of all critical body areas was good, both for the 10-year and 6-year dummies. The front passenger airbag can be disabled to allow a rearward-facing child restraint to be used in that seating position. Clear information is provided to the driver regarding the status of the airbag and the system was rewarded. All of the restraint types for the which the 2 Series Coupé is designed could be properly installed and accommodated in the car.

The 2 Series Coupé has an ‘active’ bonnet. Sensors in the bumper detect when a pedestrian has been struck and actuators lift the bonnet to provide greater clearance to stiff structures in the engine compartment. BMW demonstrated that the system worked robustly for different pedestrian statures and across a wide range of speeds, so the car was tested with the bonnet in the raised, deployed position. Head protection was good over almost the entire surface of the bonnet. The bumper provided good protection to pedestrians’ legs at all but the very outermost test points. However, protection of the pelvis was almost entirely poor. The autonomous emergency braking system, fitted as standard, can detect vulnerable road users as well as other vehicles. The system performed adequately in tests of its reaction to pedestrians, with collisions avoided or mitigated in many scenarios. The system’s performance was marginal when in tests of its response to cyclists.

In tests of its response to other vehicles, the autonomous emergency braking system performed adequately. A lane support system gently corrects the steering if the car is drifting out of lane and it can also intervene more aggressively in some other, more critical, situations. The speed assistance system can detect the local speed limit and presents the information to the driver, a lowing the speed limiter to be set appropriately. A seatbelt reminder is standard for a l seating positions.
