The Huayra was powered by a heavily modified Ford Y-block V8, downsized to four liters, producing 430 hp, with four Weber 48/48 IDF carburetors.

The Argentine Turismo Carretera racing series had been dominated by Ford and Chevrolet until the end of the 1960s.

But in the team there were also two outstanding figures, chief mechanic Oreste Berta, and designer Heriberto Pronello.

Still, Pronello's cars were chosen by many pilots, and the series became a showcase of advanced design and technology.

[1] The name was suggested to Pronello by a visual artist friend of his upon seeing the car being tested in the wind tunnel.

In 1969, Heriberto Pronello signed with Ford Motor Argentina to build six cars for the make's official Sports-prototype and Turismo Carretera teams.

Ford would now provide the F100 V8 engines, but Pronello would have to finance the project, until one condition was met: the car had to be among the four fastests in one of the first four races of the championship.

In the beginning, Pronello himself tested the car on the street and on the Oscar Cabalén racetrack in Córdoba.

On April 22, the car was being tested by Pascualini in Buenos Aires when it caught fire and was almost completely destroyed.
