NSKK
Despite Caracciola's protests, Lang was declared the 1939 European Champion by the NSKK ("Nationalsozialistisches Kraftfahrkorps", or National Socialist Motor Corps)—although this was never ratified by the AIACR, and Auto Union driver Hermann Paul Müller may have a valid claim to the title under the official scoring system—and motor racing was put on hold upon the outbreak of war.
