サファリラリー
Herrmann drove his Datsun P510 UWTK to fifth place at the 1969 Safari Rally, then known as the "East African Safari Rally", after retiring with a Porsche 911 a year earlier. He went on to win the event twice when it became part of the International Championship for Manufacturers (IMC), in 1970 with a Datsun 1600 SSS and in 1971 with a Datsun 240Z. In 1972, he took his 240Z to fifth place. His IMC events outside his home country resulted in retirements, except for a 17th place at the 1971 RAC Rally.
