Fiat Abarth OT 1300

The Fiat Abarth OT 1300 was a successful Group 4 sports prototype that Abarth built between 1965 and 1968, with a fibreglass body over a bespoke tubular frame. It was derived from the open-topped Abarth OT 1600 Sport Spider and entered production in May 1965. After the first fifty cars it won Group 4 homologation, and a revised Series II followed with a wider chassis and a new front end. Its best known feature was the Periscopio, an off-centre periscope-style vent that cooled the driver. Abarth's own oversquare engine displaced 1,289 cc and claimed 147 hp in the first series and 157 hp in the second. Race wins included the 1966 Nurburgring 500 km and the 1967 Hockenheim Grand Prix, and a 1,946 cc derivative, the OT 2000, was built in about twenty examples.
