Mercedes-Benz is the pioneer in automotive safety. No other car manufacturer carries out such intensive research in this field and has brought so many crucial innovations onto the market. Ever since the invention of the motor car in 1886, Mercedes-Benz together with its precursor brands has been instrumental in the development of active and passive safety, setting one new benchmark after another in the process.

1900 Wilhelm Maybach develops the Mercedes 35 HP as a vehicle with exemplary road safety. Contributing factors are the long wheelbase, low centre of gravity, the engine bolted to the frame and the wide track.

1921 The Mercedes 28/95 HP is equipped with front-wheel brakes. The other passenger car models from DMG (Daimler Motoren Gesellschaft) and Benz & Cie. follow suit in 1923/24.

1931 The Mercedes-Benz 170 (W 15) is the first series production automobile with hydraulic braking system and independent front and rear suspension with swing axles.

1941 Patent No. 742 977 of 23 February 1941 for the platform frame developed by Béla Barényi.

1945 Béla Barényi develops the vehicle studies "Concadoro" and "Terracruiser" in this and the following years. Both studies are among the most important works leading up to the safety body with cell construction.

1949 Patent No. 827 905 of 23 April 1949 for the conical-pin safety door lock.

1966 Hans Scherenberg and Béla Barényi draft the classification into active and passive safety that will remain valid until the introduction of PRE-SAFE®.

1967 Safety steering system with telescopic steering column and impact absorber across the entire Mercedes-Benz passenger car range

1971 An entire package of active and passive safety measures premieres in the Mercedes-Benz SL of the 107 model series: collision-safe fuel tank above the rear axle, thickly padded instrument panel, deformable or recessed switches and levers, four-spoke safety steering wheel with impact absorber and wide padded boss, newly developed wind deflector profiles on the A-pillars, large tail lamps with ribbed surface profile for extensive resistance to soiling.

1976 The "safety steering shaft for motor vehicles" patented by Béla Barényi in 1963 debuts in the Mercedes-Benz W 123 model series as a collapsible steering column with a corrugated tube.

1978 The second generation of the ABS anti-lock braking system debuts in the S-Class of the W 116 model series. Mercedes-Benz presented a first version not yet ready for series production as early as 1970. Starting in 1980 ABS is present in all model series.
