Country - Czechoslovakia
Number of seats - 6
Weight - 1700 kg
Speed - 150 km h
Engine type - Reciprocating internal combustion engine, gasoline, four-stroke, air cooling
V-twin engine
Engine capacity - 2.97
Cyl num - 8
Power - 45.5kW (62 hp) at 3200 rpm min
The Czechoslovakian Tatra 77 (T77) is the first serial-produced truly aerodynamically designed automobile. It was developed by Hans Ledwinka and Paul Jaray, the Zeppelin aerodynamic engineer. Launched in 1934, the Tatra 77 is a coach-built automobile constructed on a central tube-steel chassis and is powered by a 75 horsepower (56 kW) rear-mounted 3.4-liter air-cooled V8 engine. It possessed advanced engineering applications such as overhead valves, hemispherical combustion chambers, dry sump, fully independent suspension, rear swing axles and extensive use of lightweight magnesium-alloy for the engine, transmission, suspension and body. The average drag coefficient of a 1:5 model of Tatra 77 was recorded as 0.2455. The later model T77A has a top speed of over 150 km/h (93 mph) due to its advanced aerodynamics design which delivers an exceptionally low drag coefficient of 0.212,although some sources claim that this is the coefficient of a 1:5 scale model, not of the car itself.
