It is said that Ferdinand Porsche was so heavily influenced by the Tatra’s newly developed flat 4 cylinder engine that he incorporated the same in his design of the Volkswagen Beetle, and was subsequently sued by Tatra.
The Tatra 87 was built by Czechoslovakian manufacturer Tatra. Powered by a rear-mounted 3.0-litre air-cooled, 90-degree overhead cam V8 engine it produced 85 hp and the car could be driven up to 160 km/hr and was ranked the fastest production cars of its time.
Its design was too ahead of her times - a fin located at the sloping rear helped to divide the air pressure on both sides of the car, a technique used in later aircraft. Tatra T87 had a drag coefficient of only 0.36. Small sets of windows in the dividers between the passenger, luggage space and engine compartments, plus louvres provided air for the air-cooled engine but its negative aspect was it allowed minimal rear visibility. Its entire rear segment could be opened, to service the engine. Its front doors were "suicide doors" (i.e. rear-hinged doors).
