Abarth

The Fiat-Abarth 750 is a compact sporting series of cars manufactured by Abarth & C. of Turin, Italy in the 1950s and 1960s. The cars used the floorpan and often the bodywork of the Fiat 600 but were fitted with Abarth's modified engines. Abarth also offered a number of bodyworks by other designers for the 750 and its derivatives, most famously by Zagato. There were also other derivatives, which were sold as the Fiat-Abarth 850, Fiat-Abarth 1000 and Abarth Monomille.

The Abarth 850 spider has bodywork by Carrozzeria Allemano and was first shown in the spring of 1960. A coupé version, of which only 32 units had been built, followed the next year. The 850 TC berlina was introduced towards the end of 1960. Originally built to Group 2 touring car specifications, it was manufactured between 1961 and 1969. It uses the Fiat 600 bodywork with some modifications, most notably a boxlike structure ahead of the front bumper which held the engine's oil cooler. Between 1962 and 1971 the 850 cc and 1,000 cc class cars won hundreds of races all over the world and were commonly called "Giant Killers" due to their superior performance over much larger cars.
