Mercedes-Benz - Crash test preparations - Hanna Paul, Crash Test Dummy Engineer
With the world’s first public crash test involving two fully electric vehicles, Mercedes-Benz is going above and beyond not only the legal requirements but also those of the ratings industry. Euro NCAP stipulates a frontal impact test using a 1,400 kg trolley with an aluminium honeycomb barrier replicating the front of another vehicle. In accordance with the specifications, the test vehicle and the trolley collide with an overlap and at a speed of 50 km/h. Mercedes-Benz, however, used two real vehicles, an EQA and an EQS SUV, which are significantly heavier at around 2.2 and three tonnes respectively. In addition, both models were faster, each going 56 km/h, which meant that the overall crash energy was considerably higher than required by law. The vehicles’ extensive deformation following the collision may seem alarming to the non-expert. For the Mercedes-Benz engineers, however, it shows that the vehicles were able to effectively absorb the energy of the collision by deforming. As a result, the passenger safety cell of both electric models remained intact and the doors could still be opened. In an emergency, this would make it possible for occupants to exit the vehicle on their own or for first responders and rescue personnel to reach them. The high-voltage system in the EQA and the EQS SUV switched off automatically during the collision.

Mercedes-Benz tested the latest generation of brake control systems on drives in Arjeplog, Sweden, near the Arctic Circle. For more than 20 years, an official branch of the Sindelfingen plant has existed here: its very own test centre for testing in the most extreme conditions. In addition to the EQE, EQS, EQS SUV and EQE SUV, models of future vehicle generations based on future platforms were also used in the drives across a frozen lake and up the region’s highest mountain.“During the test drives, our team is primarily concerned with safety, efficiency and driving comfort. The development team tunes the brake control systems individually for each model series – and pushes them to their physical limits.”Christoph Böhm, Head of Brake Control Systems, Mercedes-Benz AGOn the way to an all-electric future, the team is working on a new generation of stability control systems. These make use of the properties of the electric drive to precisely control the torque at the wheels. Most drivers will probably never notice how hard their Mercedes-Benz vehicles work to keep them out of dangerous situations – for Böhm and his team, this is the definition of a job well done.
