In 1962 Ernst Fiala came to the rescue. For the crash experiments conducted by Karl Wilfert and his team, Fiala designed a hot-water rocket that powers the vehicles without the use of a tow line. Fiala received critical advice for his design from the Institute for the Physics of Jet Propulsion based at Stuttgart Airport. Mounted on a single-axle trailer, the apparatus was attached to the rear of the test vehicle and consisted of a pressure tank, a fast-opening valve and a discharge nozzle. To create thrust, the tank was three-quarters filled with water prior to the experiment and heated until the water temperature reached around 260 degrees Celsius. When the valve was opened, this excess pressure accelerated the car and rocket ensemble to speeds in excess of 100 km/h.
The introduction of the hot water rocket in 1962 also led to improvements in the test track. Reinforced concrete was used for the runway, and the test vehicles and propulsion system were now guided on rails. A fence was also erected to prevent cars landing in the stream. Such clear improvements to the test facilities were not only important for in-house testing. From 1962 to 1967 Mercedes-Benz also carried out testing on new types of crash barriers on behalf of the State of Baden-W├╝rttemberg. In addition, in 1964 the test strip was lengthened from 65 metres to 90 metres in order that heavier passenger cars such as the 600 from the W 100 series could also be subjected to crash testing.
