About the small overlap front test

Small overlap front: passenger-side

Rating applies to 2017-23 models

Tested vehicle: 2017 Mercedes-Benz E 300 4-door 4wd

The Mercedes-Benz E-Class was redesigned for the 2017 model year. Passenger-side small overlap frontal ratings are assigned by the Institute based on a test conducted by Mercedes-Benz.

Passenger restraints and dummy kinematics The dummy’s face largely remained in contact with the frontal airbag, but its head still moved too far to the right toward the gap in coverage between the frontal and side curtain airbags. The side curtain airbag deployed and has sufficient forward coverage to protect the head from contact with side structure and outside objects.

Headlights

Ratings are given for 2 different headlight variations available on this vehicle.

Trim level(s)

E 300 trim equipped with Premium II package
E 300 trim equipped with Premium III package

Evaluation criteria	Rating
Low-beam headlight type	LED projector
High-beam headlight type	LED projector
Curve-adaptive?	Yes
High-beam assist?	Yes
Overall rating
Distance at which headlights provide at least 5 lux illumination:

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

High-beam assist compensates for some limitations of this vehicle's low beams on the gradual left curve.

Distance at which headlights provide at least 5 lux illumination:

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

The low beams created some glare.
