Fiat Abarth OTR 1000

The Fiat Abarth OTR 1000, also known as the Fiat Abarth 1000 OTR, was a sporting subcompact built in very small numbers by Abarth between 1964 and 1969 on the rear-engined Fiat 850. It was the top model of the wide Fiat Abarth OT series in the one-litre class and carried Abarth's Sigla 200 engine with a special cross-flow cylinder head and the firm's Radiale principle, which Abarth used for the first time on this car. The R in the name refers to that cylinder head and not to racing. Versions included a near-series Berlina Corsa for testing, a Berlina, the best known road-approved 2+2 Coupé sold from autumn 1965 to 1969, and a Bertone Berlinetta show car. The road version made 74 hp DIN and the racing version up to 106 hp, and possibly only 35 cars were built, eight of them for the American market.
