From the invention of the motor car itself through to today’s intelligent driver assistance systems, Mercedes-Benz has consistently treated safety as a top priority when engineering vehicles.

For 140 years, we have designed and created technologies that not only protect occupants, but have also helped define modern expectations around car safety and road safety more broadly.

What sets this history apart is its continuity. Rather than isolated breakthroughs, Mercedes-Benz safety innovation is a layered progression – each new development building on decades of research, real-world data and rigorous testing.

Passive safety: the foundations of protection

Early safety thinking focused on mitigating the effects of a crash. These ‘passive safety’ innovations remain fundamental to every modern vehicle today.

The most significant milestone came with the introduction of the crumple zone in 1959. Developed by engineer Béla Barényi and debuted in the Mercedes-Benz S-Class W 111 Saloons, this concept allowed the front and rear of a car to deform in a controlled way, absorbing energy and protecting occupants inside a safety cell.

This ‘safety bodyshell’ fundamentally changed how cars were designed. Rather than relying on rigidity alone, cars were designed to manage crash energy more intelligently – an approach that remains a core part of vehicle design today.

Over time, this foundation was strengthened with other innovations such as the seatbelt tensioner and driver's airbag, and reinforced passenger compartments. These systems work together to reduce injury in the event of an accident, contributing to high car safety ratings across the industry.

Active safety: preventing accidents before they happen

While passive systems protect occupants in the event of a crash, the next evolution focused on avoiding accidents altogether.

Mercedes-Benz played a key role in introducing active safety technologies like Anti-lock Braking Systems (ABS) – developed in partnership with Bosch – which prevent wheel lock-up and allow drivers to maintain steering control under heavy braking.

This was followed by the Electronic Stability Program (ESP), also jointly developed with Bosch and introduced in the mid-1990s. By automatically applying brakes to individual wheels and adjusting engine output, ESP helps prevent skidding and loss of control, particularly in slippery conditions.

These technologies marked a turning point in road safety. Rather than reacting to an incident, the vehicle could actively intervene to help the driver maintain control, significantly reducing the likelihood of a crash.

The future of safety

Looking ahead, Mercedes-Benz is working towards a long-term vision of accident-free driving. Central to this is the development of increasingly advanced driver assistance and automated driving systems.

One of the most significant steps is DRIVE PILOT, the world’s first SAE Level 3 automated driving system approved for use in certain conditions, and currently only available in Germany, California and Nevada. This technology allows the vehicle to take over specific driving tasks, reducing driver workload and the risk of human error.

Future developments will build on this foundation, combining artificial intelligence, advanced sensors and vehicle connectivity. Cars will increasingly be able to communicate with each other and with infrastructure, identifying risks earlier and responding more effectively.

Continuous progress

From the earliest days of motoring to today’s intelligent systems, Mercedes-Benz has played a defining role in the evolution of car safety.

Each innovation – whether a structural breakthrough like the crumple zone or a digital system like PRE-SAFE® – has contributed to a broader goal: making driving safer for every road user.

As technology continues to evolve, that commitment remains unchanged. The next chapter of road safety will likely look very different, but it will still be shaped by the same principle that has guided Mercedes-Benz for more than a century: continuous progress in the pursuit of safer vehicles.
