Stuttgart – 2009 is a year in which Mercedes-Benz celebrates several anniversaries in the safety field: in August 1939 the safety pioneer Béla Barényi started his work in Sindelfingen. He invented for example the principle of the crumple zone, a trailblazing innovation which entered series production at Mercedes-Benz in 1959. With the help of its in-house accident research function, which was founded in 1969, Mercedes engineers in the following years have developed several groundbreaking innovations in passenger car safety. Now it is time for a look behind the scenes, and in this anniversary year, Mercedes-Benz is using the ESF 2009 research vehicle to reveal what its safety specialists are currently working on – with a time horizon that often extends well into the future.

The ESF 2009 is the first Experimental Safety Vehicle to be built by Mercedes-Benz since 1974. Like its historic predecessors, it illustrates trailblazing innovations in the field of safety and makes the progress achieved clearly visible. These amazing but by no means crazy ideas include inflatable metallic sections which give more stability to structural components within fractions of a second, as well as the so-called "Braking Bag". This airbag housed within the vehicle floor is deployed when a crash is deemed to be unavoidable, and uses a friction coating to support the vehicle against the road surface. The ESF 2009 will be premiered on 15 June 2009, at the Enhanced Safety of Vehicles (ESV) Conference in Stuttgart.


"Safety is a central element of the Mercedes-Benz brand. In this respect we have been setting the pace in the market for almost 70 years. For the benefit of our customers and for road users in general. The ESF 2009 shows that we still have plenty of ideas and the absolute will, to lead the automobile industry in this field even in future", says Dr. Dieter Zetsche, Chairman of Daimler AG and CEO of Mercedes-Benz Cars.

The ESF 2009 was developed and built completely in the test vehicle workshops in Sindelfingen. This safety research vehicle based on the Mercedes S 400 HYBRID features more than a dozen safety innovations, most of which are fully functioning in demonstration mode. "With the ESF 2009, we have chosen this particular time to clearly demonstrate the innovative strength of Daimler. Anybody examining the ESF 2009 in detail will recognise that more safety and improved energy efficiency are not necessarily a contradiction in terms. We want to make progress in both fields with new, trailblazing ideas ", says Dr. Thomas Weber, the member of the Daimler Executive Board responsible for corporate research and development at Mercedes-Benz Cars.

The following five innovations on the basis of the S 400 Hybrid are among the highlights of the ESF 2009:
