The Fiat Abarth 850 TC, is a sporty small car model of the Italian car manufacturer Abarth.
History
By the end of 1960 Abarth started building the Abarth 850 TC the TC standing for Turismo Competizione for track and road use, as the entry-level model of the series, it was offered between 1960 and 1966 in different versions based on the small Fiat. the road version of which remained in production until 1966. Fiat supplied the cars without some mechanical parts such as crankshaft, brakes, carburettor and exhaust which were mounted by Abarth transforming the 600 into the 850 TC the race versions produced until 1969.
During 1962, two main variants of the 850 were built, the TC Nürburgring (to pay homage to the victory of the 850TC in the homonymous circuit), whose engine supplied 55 CUNA horsepower at 6500 rpm. This version was built to commemorate the class victory obtained in 1961 by an Abarth 850 at the Nürburgring 500 kilometres also the TC/SS, with engine power 57 CUNA horsepower at 6500 rpm. The distribution of weight was 45 % to front axle, and 55 % to the rear axle. Towards the end of 1962, this version was renamed the "850 TC Nürburgring Corsa".

Also in 1962, the 850 was joined by the FIAT-Abarth 1000 Berlina, which was also derived from the FIAT 600, but had the 982 cm³ engine, with 60 CUNA horsepower with cylinder head with peripherical combustion chambers. With race models with many various options. With these versions, Abarth brought a large number of innovations to small cars, i.e., disc brakes on all four wheels, a 5-speed gearbox and spring and shock absorber suspensions since the leaf springs of the 600 were not capable of provide adequate road holding.
