Why it matters
The 1300 OT (Omologato Turismo) was Abarth's own twin-cam GT after its supply contract with Simca ended, and it dominated its class in 1966-68. The roof-mounted 'periscope' air intake that gave relief from cockpit heat became its signature.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
When Chrysler took over Simca at the end of 1964 the Abarth-Simca contract lapsed, so Abarth developed a new 1300 cc four-cylinder of its own. The OT coupe was built between May 1965 and March 1966, at least 50 examples, to meet homologation requirements. The 1966 season brought a 1-2-3 class result at the Monza 1000 km and the Division 1 championship, repeated in 1967.
Early cars had Fiat 850 underpinnings, strengthened by engineer Mario Colucci with coil-over front suspension on A-arms and Abarth trailing arms at the rear. When early cockpits proved too hot, the periscope intake was added.
