OT 1000 at Geneva Motor Show.
Fiat Abarth OT 1300 Prototipo
Abarth Simca 1000
OT 1600 (850 based) featured heavily revised suspension, larger wheelarches with extensions to house the bigger wheels, comprehensive instrumentation (revcounter, speedometer, water and oil temperature, oil pressure and fuel level) and different seats. Behind the revised front grille sat two radiators, one each for the water and oil. Disc brakes were fitted all round. The engine was a 1592cc (86x68.5mm) dohc twin-spark with two twin carburettors and 154bhp @ 7,600rpm. A four or six speed transmission could be fitted, complete with limited slip differential.
1965 saw the birth of yet more 982cc engined cars. The 62bhp unit was fitted to both the 850 Spider and the new 850 Coupé, creating in both cases an OT1000. A Coupé with 74bhp (mainly thanks to the fitment of two twin carburettors), known as the OTS1000 was also offered. At the same time a Bertone Racer (ie 850 Spider with a permanent hardtop) was fitted with a more highly tuned 'radial' engine (hence the designation OTR1000), still 982cc but with 74bhp. For motorsport the OTSS1000 was built which managed to extract 90bhp from the OTS engine.
Abarth has his 695 SS based on this latest 500 body, and there is the usual assortment of competition cars tightly bunched on a small stand.
