At the same time as the Coupé, Fiat also introduced the convertible sporty two-seater Spider, with the original 843 cc engine tuned to produce 49 hp (37 kW) which allowed it to reach a top speed of 145 km/h (90 mph). The body was designed and built by Bertone. The folding roof section made of fabric could be stowed away completely under a rear flap. The Bertone design also featured smooth, essential lines and simple yet elegant details, such as the recessed headlamps equipped with tilted plexiglass covers to follow the lines of the wings, and the dihedral side panels inspired by Bertone's 1963 Corvair Testudo.This engine ran counterclockwise, a unique feature compared to other engines.
Abarth produced a tuned version of the Spider, known as the Fiat Abarth OT 1000 Spider. With engine displacement increased to 982 cc, it produced 61 hp (45 kW) and 58 lb·ft (79 N·m) of torque.
