A proving ground is opened near Ehra Lessien on the southern edge of the Lüneburg Heath. In its final form, the site features a 100-kilometre long test track with a variety of surfaces and gradients. The Volkswagen Group tests its vehicles here under everyday conditions with the help of modern equipment. A driving simulator is installed in 1970, enabling certain test programmes to be carried out safely. Volkswagen increases its staff by hiring engineers and technicians to strengthen research and development activities.
