Horch 8 classic cars for sale

History and Development of the Horch 8

Horch launched the 8 model range in 1926, setting a benchmark for advanced luxury vehicles in Germany. Born from the expertise of chief engineer Paul Daimler, the Horch 8 introduced a 3.2-litre straight-eight engine with twin overhead camshafts – a configuration almost unheard of at the time in Europe. With continuous development, later engines reached displacements of 3.4 to 5.0 litres and incorporated features such as coupled cylinders and robust crankshaft bearings for superior smoothness.

The initial Horch 303 replaced the Horch 10 as a larger, more powerful luxury vehicle and was available as a touring car, Pullman saloon and Pullman convertible. Successive variants, such as the 305, 306, 400, 500, and later the Horch 780, expanded the technical and luxurious capabilities of the series. Production of Horch 8 models spanned until 1935, after which the line was succeeded by models including the 830, 930, 850 and 951. Their notoriety was solidified by the merger of Horch into Auto Union A.G. in the 1930s, which would shape German automotive history.

Model History

The Horch 8 family started with the Type 303, a direct evolution from the Horch 10. Key advancements included the move away from six-cylinder engines toward the technologically ambitious inline-eight. The series rapidly diversified – the 305 and 306 delivered more power and refinement; the 304 introduced a cabriolet version with a shorter wheelbase. The Horch 400, revealed at the 1930 Paris Auto Show, showcased a 4-litre DOHC engine. The 500 established a new high point with a 5-litre engine producing 100 hp, setting standards at the luxury end of the market.

By 1932, the Horch 780 arrived with further improved engine technology under the guidance of Fritz Fiedler – later a major figure at BMW. This last development in the model’s lineage was produced in limited numbers, symbolising Horch’s pursuit of innovation until the merger into Auto Union led to new model generations.

Highlights and Distinguishing Features

The Horch 8 models stood apart through their advanced engineering – particularly the straight-eight engine with twin overhead camshafts, unusual for the time. Their construction boasted spacious, luxurious interiors with bespoke coachwork. Many 8 models were built as exclusive Pullman saloons and elegant cabriolets, often featuring distinctive three-part panoramic windscreens. The custom bodies established Horch’s reputation for craftsmanship and technical confidence.

Horch 8 cars remain extremely rare: for example, only about 250–300 units of the final Type 780 were made, and just 16 are known to survive worldwide. Their prestigious aura is matched by their regular presence and success at concours events and their appeal to connoisseurs of 1930s German automotive technology.
