Derichs

A singleton D34 chassis was run in the German F3 series for Hans Hargarten, it used a Ford engine and was never very competitive, the best result was a third place in a poor field at Salzburg.

1975

Erwin Derichs ran his own Ford powered car in the German F3 championship, it wasn’t very competitive and recorded no top 6 finishes.

1976

At least two cars were built for 1976, designated the D36 one was fitted with a BMW engine the other with a Ford. Results were poor in the German F3 championship with a best finish of tenth, taken by Derichs himself.

1977

Erwin Derichs ran his own Ford powered car in the German F3 championship, it wasn’t very competitive and recorded no top 6 finishes.
