Manufactured by Tatra, Kopiivnickå vozovka, as, Koprtvnice, Czechoslovakia Efforts to build an automobile with a higher performance at a low consumption introduced new trends in car designing. One was streamlining. At the 1934 International Car Exhibition in Berlin there were four cars which could have been said to start the era of streamlined vehicles: the Tatra 77, Chrysler-Airflow, Steyr 32 PS, and a 1 litre DKW.
The prototype of the Tatra 77, which became the first production car with a streamlined body, had an air-cooled V8-engine located behind the rear axle. The engine was easily accessible by lifting the fin-shaped rear bonnet. The gearbox was located in front of the rear axle. Ever since, this arrangement has been used in almost all cars with rear- mounted engines. The frame consisted of a central member and cross-members, which carried a well-styled streamlined body utilizing the whole width of the vehicle. As a result, three people could sit next to the other on both front and back seats.
The prototype Tatra had the steering located in the centre of the car, and the seats beside the driver were moved slightly back to provide more legroom and avoid the inner wheel arches. Behind the back seat, between the gearbox, the clutch, and the half-shaft drive, there was a roomy luggage compartment.
The Tatra 77 proved that building an air-cooted engine was no longer a technical problem.
The 3 litre engine with bore and stroke of 75x84mm was rated at 44.1kW (60hp) at 3500 rpm, developing a speed of 145km/h (90mph). After the first 100 cars built in 1934, the engine was re-bored to 80mm in order to increase the acceleration, giving a capacity of 3.4 litres. It developed 53kW (72hp). The next
Type 77 A
In 1935 there was further developed to the type 77A . This was 100 kg heavier, had a 10 cm extended wheelbase , 80 mm drilled engine with larger displacement (3378 cc) and higher engine power (70 hp / 51 kW at 3500 / min), slightly improved handling characteristics and a top speed of about 150 km / h. The Type 77 A is easy to distinguish on the - for the first time in a Tatra - arranged in the middle of the third headlights from its predecessor. When the improved successor Type 87 appeared in 1936 , the T 77 A was not discontinued, but continued to be built until 1938 because of the continuing interest in 154 copies.
A total of 255 vehicles (without prototypes) were made of the Type 77 and Type 77 A in all versions, whereby due to the frequently realized customer wishes, hardly one car resembled the other.
