Ruins of Opel’s legendary test track still hidden in German forest

In the early 1920s, Opel constructed a remarkable 1.5-kilometre oval test circuit, unlike anything seen before in Europe at the time. It was designed as a high-speed proving ground and quickly gained attention, effectively becoming one of the fastest road-like tracks on the continent and a major attraction for motorists and engineers alike, AzerNEWS reports.
