EPA estimates come from standardized lab tests so cars can be compared fairly; real-world mileage depends on speed, weather, load, tires and driving style.

2017 Mercedes-Benz SLC-Class crash-test ratings

NHTSA 5-Star Safety Ratings for the tested versions. More stars mean a lower chance of serious injury in that type of crash. Rollover risk is NHTSA's estimated chance of rolling over in a single-vehicle crash.

2017 Mercedes-Benz SLC-Class NHTSA 5-Star Safety Ratings
Tested vehicle	Overall	Frontal	Side	Rollover	Rollover risk	Forward collision warning
2017 Mercedes-Benz SLC-Class C RWD	Not rated	Not rated	Not rated	Not rated	—	Optional

Source: NHTSA 5-Star Safety Ratings (New Car Assessment Program), checked Oct 26, 2026.

Star ratings compare vehicles of similar size and weight; a frontal rating for a large pickup is not directly comparable with one for a small car.
