Tatra T77 

The first prototype of the new aerodynamic Tatra concept was constructed in 1933, named the type T77. This prototype was severly tested by Tatra engineers. Although it was only a pre-production prototype Tatra did print a brochure for this car in 1933 with descriptions, pictures and technical specifications. The car was equipped with a rear-mounted air-cooled 90 degree V8 engine with a cylinder capacity of 2970 cc and a power output of 60 hp @ 3500 rpm. The engine transmitted its power to the driven rear wheels by means of a four-speed gearbox, bolted together with the engine and the axle drive as one big monoblock. This monoblock was enclosed by the forked welded box frame of the chassis, which also housed the gear-change rods, cables and fuel lines. The monoblock could be easily removed from the car for repairs and changing parts. High-speed road testing in Italy had proved that directional stability was improved by re-positioning of the air vents onto the engine cover.

The Tatra management decided to take the T77 into production on a small scale. The cars were almost totally hand-built and aimed at the top of the automobile market with their well equipped interior and leather upholstery.
The world's first serially produced aerodynamic car with a rear-mounted air-cooled engine was introduced to the press on March 5th, 1934, in Prague. The T77 was a real sensation, overtaking the world's motor car industry by several decades. Shortly after its introduction in Prague the T77 was shown at the Berlin Motor Show in 1934 where it was hailed by the motoring press. The T77 was like nothing else available at that time. The body was based on an almost all-steel monocoque construction with timber infill. The wings and headlamps were integrated with the body, running boards were absent, door hinges and handles were sit into the body and the underbody was made as smooth as possible, like the body, avoiding protrusions. The large tailfin running over the rear end of the car was used to decrease the effects of side winds and increase the roadholding, but also had a large contribution to the car's excentric and futuristic image! The five passengers sat between the axles in the most comfortable position, while the luggage, battery and two spare tyres were carried in the front. The main luggage compartment was located on top of the rear suspension, between the rear passengers and the engine. The engine was placed backwards to the rear axle, which gave the 1700 kg heavy car an 'interesting' roadholding.

An interesting feature equipped on a few of the T77 models was the steering wheel in the centre of the dashboard. The front seat passengers where seated on either side of the driver and the seats placed slightly back. This unusual feature was also fitted in the Panhard Dynamic of that time. All other T77's had the steering wheel on the right hand side as they drove on the left-hand side of the road in Czechoslovakia before W.W.II, like in various other European countries.

In it's introduction year, 1934, the T77 was used for the '1000 Czechoslovakian miles' race. It finished in 4th place in the absolute classement.
