Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Mercedes-Benz C-Class was redesigned for the 2015 model year.

Structure

The driver space was maintained well, with maximum intrusion of the lower interior of 10 cm at the footrest. Upper interior intrusion measured 4 cm at the upper hinge pillar and instrument panel.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

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.

Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Mercedes-Benz C-Class was redesigned for the 2015 model year. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Mercedes-Benz as part of frontal crash test verification.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity. Head acceleration from the roof rail hit was low.

Restraints and dummy kinematics

Dummy movement was well controlled. During rebound, the dummy's head hit the roof rail.

Side crash test ratings can be compared across vehicle categories.

The Mercedes-Benz C-Class was redesigned for the 2015 model year. Side ratings are assigned by the Institute based on a test conducted by Mercedes-Benz as part of side crash test verification.

Injury measures

Driver — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Passenger — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Head protection

Driver — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Passenger — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Roof strength test ratings can be compared across vehicle categories.

In the test, the strength of the roof is determined by pushing a metal plate against one side of it at a slow but constant speed. The force applied relative to the vehicle's weight is known as the strength-to-weight ratio. This graph shows how the ratio varied as the test of this vehicle progressed. The peak strength-to-weight ratio recorded at any time before the roof is crushed 5 inches is the key measurement of roof strength.

A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor.

Low beams

On the straightaway, visibility was inadequate on both sides of the road. On curves, visibility was inadequate in all 4 tests.

The low beams created some glare.

High beams

On the straightaway, visibility was good on the right side of the road and fair on the left side. On curves, visibility was fair on the gradual left and gradual right curves and inadequate on the sharp left and sharp right curves.

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway and all 4 curves.
