78380roadGermany
Engine
4.9L inline-six, overhead cam, 100 bhp
Colour
Royal Blue

The Horch Type 780 B was among the most refined products of the German marque, produced in limited numbers between 1932 and 1934 with a 4.9-litre overhead-cam inline engine developing 100 bhp. This example, the third-to-last 780 B chassis built, was delivered in 1934 and later surfaced in Belarus, where it was found in 2005 without its original coachwork. Acquired by Horch Classic GmbH, it received a seven-year restoration pairing the chassis with a Gläser-style Sportcabriolet body originally built for a Horch 710, winning a Best Restoration award at the 2013 Schloss Dyck Classic Days concours.

Maintenance & restoration

  1. Modification
    Horch Classic GmbH

    The original gearbox was replaced with a contemporary Getrag five-speed transmission to improve drivability.

    This modification was carried out as part of the broader restoration programme.

  2. Restoration
    Horch Classic GmbH

    A comprehensive seven-year restoration was undertaken, encompassing structural frame cleaning and selective replacement of corroded sections, overhaul of the engine (with new bearings, pistons, and modern radial oil seals), front and rear axles, differential, gearbox, and steering gear. Copper fuel lines and stainless steel exhaust were fitted. The body's timber framework, outer panels, and hood bows were found in sound condition and retained where feasible. The car was finished in Royal Blue with grey leather interior embroidered with the marque's logo and a grey cloth hood.

    The restoration drew on extensive research and period-correct components; supporting photographs of the process are included in the car's file.
