August Horch (12 October 1868 – 3 February 1951) was a German engineer, automotive pioneer, and founder of both Horch and Audi, two of the four brands later united under the Auto Union emblem that forms the basis of the modern Audi logo.
The Auto Union Type C is a Grand Prix racing car developed for the 1936 and 1937 European Championship seasons under the 750-kg formula, and represents the pinnacle of the mid-engined V16 design lineage created by Ferdinand Porsche.
