The E450’s mild hybrid technology contributes somewhat to fuel-saving during city driving and coast-down phases, making it a relatively efficient choice in this segment.
Safety and driver assistance
Safety is paramount in the E-Class, with features such as active brake assist that can automatically apply brakes to avoid collisions, blind spot and cross-traffic alerts, and advanced adaptive cruise control that manages distance and speed intelligently.
Mercedes-Benz’s Pre-Safe system anticipates collisions and prepares the vehicle by tightening seatbelts and adjusting seating positions. The E-Class also includes a driver drowsiness monitor and attention assist to reduce accident risks.
Recent model-year E-Classes achieve strong crashworthiness scores in multiple safety evaluations, credited to their robust body structure and numerous airbags. The integration of semi-autonomous driving assistance further reduces driver fatigue on highways.
