Mercedes-Benz ESF 2009 Experimental Safety Vehicle

The Mercedes-Benz ESF 2009 Experimental Safety Vehicle is a safety research vehicle based on the S400 Hybrid, unveiled in 2009 at the Enhanced Safety of Vehicles Conference in Stuttgart. It served as a test bed for protection systems that Mercedes-Benz later put into production, among them the Spotlight function, introduced as Night View Assist Plus on the CL-Class (C216) in 2011, and the Beltbag, car-to-X communication, adaptive full-LED high beam and PRE-SAFE Impulse, all introduced on the S-Class (W222) in 2013. Other features shown on the vehicle include a braking bag, a child protect system, a hybrid battery shield, interseat centre airbag protection, PRE-SAFE Structure and PRE-SAFE 360 degree, a rear seat camera, Side Reflect and size-adaptive airbags.
