The Tatra 70 was the successor of the large model T31, which was manufactured at the Tatra factory located at Nesselsdorf in 1931.
This luxury vehicle had a water-cooled six-cylinder OHC engine with a capacity of 3406 cc and brakepower of 65 hp (48 kW). The engine camshaft was driven by a Bevel,which gave power to multiple dry clutch discs and a 4-speed gearbox to the rear wheels. The achievable maximum speed of this approximately 2,400-kilogram (5,300 lb) car was 110 km/h (68 mph). The chassis had a central tube construction ; the foreground is a rigid axle with overhead Transverse leaf spring and a rear swing axle with half transverse leaf springs was installed. The wheels were designed as slices.
There were mixed 4- and 6-seater sedan bodyworks. Until 27 April 1932, 50 vehicles were manufactured.
The Tatra 70 A 1934 appeared as a successor to the Type 70. Its engine and drivetrain were in line with the concept of type 70, however, the displacement was increased to 3845 cc and the performance was increased to 70 hp (52 kW). Thus, this 2,450 kg (5,401 lb) heavy car reached a top speed of 130 km/h (81 mph).
Up to 28 August 1936, about 70 vehicles were manufactured. On 23 May 1947, a T70 car built after WWII from spare parts of another car was given to Czechoslovakian President Edvard Beneš.
