Small overlap front: driver-side

Rating applies to 2015-19 models

Tested vehicle: 2016 Mercedes-Benz C 300 4-door
The Mercedes-Benz C-Class was redesigned for the 2015 model year.

Restraints and dummy kinematics
The dummy’s head contacted the frontal airbag but rolled to the left because the seat belt allowed excessive forward excursion of the head and torso. The side curtain airbag deployed and has sufficient forward coverage to protect the head from contact with side structure and outside objects.

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 dummy's head contacted the frontal airbag but rolled partway around the left side, allowing the head to move toward the gap in coverage between the frontal and side curtain airbags.

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.

Small overlap front: passenger-side

Headlights

Ratings are given for 3 different headlight variations available on this vehicle.

Trim level(s)

  • C300 trim equipped with Adaptive High Beam Assist package
Low-beam headlight type LED reflector
High-beam headlight type LED reflector
Curve-adaptive? No
High-beam assist? Yes
Overall rating

Low beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was fair in all 4 tests.

The low beams created some glare.

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

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