Previous model Tatras 77
successor Tatras 603

The Tatra 87 was a car of the luxury class with air-cooled eight-cylinder - V engine of the Czechoslovakian manufacturer Tatra . The successor to the Tatra 77 a was built  from 1937 to 1950, with an interruption due to the Second World War . A total of 3,023 vehicles left the plant in Kopřivnice (Nesselsdorf). The successor was the Type 603 presented in 1956 .

history

Type 87

The Tatra 87 was presented in 1937. It had a four-door semi-self-supporting body with a central support frame with Y-shaped arms. For the predecessor 77 a, it was still a composite construction (wooden framework with nailed, deep-drawn or driven sheet steel parts ) on a platform frame . His compared to the previous model slightly changed body shape has a c w value (determined in 1979 in the VW climatic wind tunnel and confirmed by recent measurements in the UK and Sweden) of 0.36 and was equipped with a sunroof equipped. The installation of a radio was prepared at the factory (the Telefunken IA-39 is shown in the manual).

The designers of the Tatra 87 were Hans Ledwinka and Erich Übelacker .

The displacement of the engine had been reduced somewhat while the output remained the same, the total weight had dropped by 470 kg with a somewhat shorter overall length, which is mainly due to the use of lighter materials (the engine and transmission block and other components are made of electron , an extremely light magnesium alloy ). As with its predecessor, the air-cooled V8 engine was installed in the rear of the Tatra 87, but the supply of cooling air was improved at higher speeds. Designed for the then new motorways, it reached a top speed of 150 to 160 km / h, the recommended travel speed was 135 km / h.

In 1948 the body, which had previously been designed in Art Deco , was modernized with the participation of František Kardaus - with headlights sunk into the more voluminous front fenders, modified bumpers and a modified interior (instruments in ivory instead of black) with more chrome trim parts on the dashboard. This version, built from 1948 on, is also known as the "Diplomat" model. The new front is similar to that of the smaller Tatra 600 .

From 1936 to 1950 3023 vehicles were built, of which 1371 until 1945, the remaining 1652 units from 1946. The highest annual production in 1948 was 700 vehicles.

Type 87-603

Between 1950 and 1953, some specimens were of the type 87 with the new OHV -Motor of 603 A equipped. These test vehicles were given the name Tatra 87-603 .

Prominent owners of the Tatra 87

Hans Ledwinka, the long-time designer of the Tatra wagons, as a pensioner in Munich, drove a Tatra 87 that had been restored by Ringhoffer AG in Vienna and that his friend Felix Wankel had given him. This copy is now on display in the Deutsches Museum in Munich.

Technical specifications

Air-cooled eight-cylinder - V engine of Tatra 87

The Tatra 87 engine was used for a variety of purposes, including the prototype of Hans Trippel's SG 7 swimming car (1943) and stationary power generation units. This motor was also used in the Tatra V 855 motorized snowmobile , which is based on the T87.
