Benz 20 hp "Prince Heinrich" car, 1909

After the end of the first Prinz-Heinrich-Fahrt, the participating amateur drivers as well as the specialised press and interested public regretted that almost all the prizes were won by so-called factory drivers in special touring cars. These points of criticism were addressed in the regulations for the 1909 Prinz-Heinrich-Fahrt by introducing a handicap for factory drivers and very precise regulations regarding the bodywork of the participating vehicles.

The second Prinz-Heinrich-Fahrt was held from 10 to 18 June 1909 over a distance of 1858 kilometres on the route Berlin–Wroclaw–Tatra–Lomnicz–Vienna–Salzburg–Munich. There were 108 participants, including eight Benz special touring cars with a nominal output of 20 hp/15 kW (engine capacity 2413 cc) and 50 hp/37 kW (engine capacity 5701 cc). The five 2.4-litre cars, which were equipped with a cardan drive were driven by. Otto Philipp, Edward Forchheimer, Richard Spitzner, Hans Nibel and Karl Schwartz. 

The overall winner was Wilhelm Opel in an Opel, second was Willy Pöge's Mercedes driven by Alfred Vischer; the best-placed Benz, a 2.4-litre car with 20 hp driven by Edward Forchheimer, only managed fourth place.
