No Future without a Past Continental since 1871 Continental-Caoutchouc- und Gutta- Percha Compagnie is founded in Hanover on October 8 as a joint stock company. Soft rubber goods such as hoof buffers for horses, rubberized fabrics, as well as pneumatic tires for bicycles and cars are manufactured. The rampant horse is adopted as the trademark. 1871 1882

The first German airship LZ 1 rises above Lake Constance for its inaugural flight. The gas cells are sealed with Continental balloon material. Louis Blériot, the pioneer aviator, writes history with the first flight across the English Channel. Continental Aeroplan material covers the fuselage and wings of his plane. Continental is the first company in the world to develop automobile tires with a patterned tread. The same year, specimens of synthetic rubber developed at the Bayer laboratories are successfully vulcanized at Continental and processed to make the first test tires. The first edition of the customer magazine Echo Continental is published featuring contributions from young authors such as Erich Maria Remarque and drawings by wellknown commercial artists. 1900 1904 1909 1913

In close collaboration with Daimler- Benz and Porsche, Continental repeats its pre-war successes on the track. Continental markets a rubber-metal bonding under the registered trade name of Continental Schwingmetall.It is used to isolate vibrations and noise when supporting motors. Continental adds M+S tires for winter driving to its range of conventional tires. Racing in cars fitted with Continental tires, drivers like Karl Kling, Stirling Moss and Juan Manuel Fangio win the 1952 Carrera Panamericana and the French, British, Dutch and Italian Grand Prix. Opening of the Contidrom tire testing facility on the edge of the Lüneburg Heath. 1932 1952 1951 55 1967

For the first time, the company employs more than 235,000 employees all over the world. Annual sales amount to 44 billion. The Automotive Systems division is established to intensify the systems business with the automotive industry. Continental acquires Siemens VDO Automotive AG and advances to among the top five suppliers in the automotive industry worldwide, at the same time boosting its market position in Europe, North America and Asia. Start of extensive automated-driving tests in the U.S. state of Nevada. A highly automated Continental test vehicle has covered 15,000 miles on public roads without any accidents. 1995 2007 2012 2017

Continental has built a test vehicle to enable driverless mobility, especially in cities. Called a CUbE (Continental Urban Mobility Experience), this vehicle is being trialled at the Frankfurt site.. Through its architecture, the new Continental headquarters which are to be inaugurated to mark the company's 150-year anniversary symbolize and promote the culture of innovation and interconnectivity at Continental. The new campus meets the demand for agile, flexible and interconnected collaboration throughout the entire organization, as is already common practice at Continental worldwide. 2018 The Future in Motion
