At the Turin Motor Show in the autumn of 1959, Abarth presented a range of modified berlinettas. The 750 Bialbero Record Monza disappeared to be replaced by two even sportier variants, the 700 and 850 Bialbero Record Monza, which corresponded in terms of engine capacity to two of the most popular classes in competition. It was with two 850s that Abarth made its debut at the 24 Hours of Le Mans in 1960, with the crews Féret/Spychiger and Condrillier/Guichet. The engine of the 850 Bialbero was a brilliant 847cc (62.5x69mm) 4-cylinder, capable of 73hp, which allowed a top speed of around 190km/h. The body was made by Zagato. From October 1960 the 1000 Bialbero Record Monza replaced the 850.
