Small overlap front: driver-side

Rating applies to 2017-18 models built after November 2016

Tested vehicle: 2017 BMW 330i 4-door

The BMW 3 series sedan was redesigned for the 2012 model year. For the 2016 model year, a front suspension change was made to better control wheel movement during small overlap frontal crashes. The change, however, wasn't enough to improve the car's performance in the small overlap test.

Beginning with 2017 models built after November 2016, BMW made further changes to the suspension and modified the adjoining structure. Wheel movement was much better controlled and the car's performance in the small overlap test was greatly improved. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on the driver door or adjacent B-pillar.)

Restraints and dummy kinematics

Action shot taken during the small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained well.

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

Forces on the right lower leg were just high enough to indicate a moderate risk of injury.

Low beams
On the straightaway, visibility was fair on the right side of the road and inadequate on the left side. On curves, visibility was good on both right curves and inadequate on both left curves.

The low beams never exceeded glare limits.

High beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was good on the gradual right and gradual left curves and fair on the sharp right and sharp left curves.

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway, on both left curves and on the sharp right curve.
