The ninth production Tatra T77 chassis, this 1934 example is one of only five known restored and drivable survivors of a model built in approximately 106 examples. Designed with radical aerodynamic principles—including a rear-mounted air-cooled V-8 and a stabilising dorsal fin—the T77 achieved a drag coefficient of 0.245. Originally acquired by Count Jaromír Egon Czernin-Morzin and used in an Alpine tour, the car passed through obscurity before a barn discovery in Slovakia. Following acquisition by a German enthusiast in 2005 and subsequent sale in 2007, a comprehensive, decade-long concours-quality restoration exceeding one million US dollars was completed by International Auto Restoration of Oak Lawn, Illinois.

Maintenance & restoration

  1. 2012Restoration
    International Auto Restoration

    A comprehensive, no-expense-spared concours-quality restoration began, encompassing bodywork, interior, and full mechanical overhaul. Decayed ash wood framing was replicated by a French artisan after 3D scanning of surviving structure; the factory sunroof was replaced with a solid roof; new front and rear bumpers were fabricated; the interior was retrimmed in period-correct gray leather with walnut veneer dashboard. The air-cooled V-8 received new pistons, connecting rods, and valves, with a new-old-stock carburettor sourced from the Czech Republic. The transaxle, braking, starting, and electrical systems were overhauled; front suspension components were replicated where originals were beyond repair; the steel box frame was repaired; trafficator signals were restored; and three replacement wheels were fabricated to match the originals. Total investment exceeded one million US dollars.

    The restoration was completed over approximately a decade and is fully documented at a dedicated website. The workshop is located in Oak Lawn, Illinois.
