Horch 12, Type 670 sports convertible, 1932


The Horch 670 Sport-Cabriolet designed by Hermann Ahrens was presented at the Paris Motor Show in the autumn of 1931, right in the midst of the world economic crisis. The V12 designed by senior engineer Fritz Fiedler exhibited engine technology at its very best: a crankshaft with seven bearings, twelve balance-weights and an additional vibration damper ensured maximum running smoothness. The hydraulic valve-clearance adjuster was way ahead of its time. However, this impressive engine was to remain an exclusive rarity. In all, only 58 Cabriolets were produced, together with 20 twelve-cylinder Type 600 Pullman saloons.
