 This theoretical study followed Maurice Olley’s paper “Road Manners of the Modern Car” and established ex-Rolls-Royce engineer Olley and Eberhorst as two of only a handful of engineers capable of mathematically defining the essential factors in car handling.Eberhorst’s contribution was to show how the several constants in Olley’s complex equations could be established experimentally.In 1953 Eberhorst returned to Germany as General Manager for Technical Development at a reviving Auto Union.
