In the development of new models, Mercedes-Benz engineers have by tradition accorded high priority to safety and the environment at all times. After the invention of the automobile in 1886, it was initially a question of giving the new means of transport operational reliability and easy handling. Once the motorized vehicle had established itself as a reliable means of transport, the engineers and technicians were able to devote themselves to new development fields which had been given little attention before. Among other things, this included the improvement of active and passive safety. Mercedes-Benz has always played a pioneering role in this field as well, thereby positively influencing automotive development throughout the world. A crucial era in this respect was the 1960s and 1970s. Men like the ingenious Mercedes-Benz design engineer Béla Barényi contributed substantially to the enhancement of safety with the development of the passenger safety cell. Other milestones were the anti-lock braking system (ABS) and the airbag.
