Why it matters

A homologation special derived from the Fiat 850 Coupe for FIA Group 3 racing, with a special radial-valve head on a 982 cc engine. Racing bodies including the SCCA banned it, which limited both its competition use and the number of roadgoing cars built.

02Production & history

Production

Every figure says what it counts.

No production figures recorded yet.

History

The 1000 OTR was introduced in late 1965 as a homologation derivative of the Fiat 850 Coupe. Fiat supplied the body shells and Abarth modified the cars to its own specification, with a radial-valve head meant to match the efficiency of Abarth's twin-cam head without its complexity.

Few were built. Surviving cars are mainly known through auction and concours records, which describe the model as rare, low production and well documented.
