The greater the variety of different models and assistance systems, the more testing is required by the OEMs in the developmental phase, in terms of both hardware and software. Since Formel D has systematically built up vast expertise in this area and has gradually expanded its range of services, manufacturers are outsourcing numerous testing services to the Group. The portfolio of the internationally represented service provider includes everything required to test drives on public roads as well as non-public test sites and race tracks – from preparation and organization to execution. In 2019 alone, Formel D covered about 20 million miles (32.5 million km) for testing worldwide. Vehicle types of all variations, from passenger cars and commercial vehicles to motorcycles, are being tested in all parts of the world. Formel D conducts off-road, poor road conditions, cross-country, city and highway testing under a wide range of weather conditions with a temperature range from -58 °F to +86 °F (-50 °C to +30 °C). While the automotive service provider is conducting the various testing projects, it also collects environmental data for the development of driver assistance systems and associated services, including data on route profiles, traffic volumes, as well as the frequency of road signs and traffic lights. This allows the Group to position itself as an important partner for the future of the industry.
