Klaus Ludwig was one of Germany's best race drivers that did not enter Formula One. Unlike Hans-Joachim Stuck, Rolf Stommelen, Harald Ertl, Hans Heyer and Jochen Mass, he never even raced even single seaters (just doing a few test drives). He is called "König Ludwig" for his success with touring cars and in sports car racing. In the 1970s, Ludwig drove Ford in the Deutsche Rennsport Meisterschaft, winning in 1979 with a Kremer-Porsche 935. Wikipedia
