Ford Mustang B1

Vehicle Overview

The Ford Mustang OSI: Who, precisely, conceived the OSI Mustang is lost to history, but it was clearly more than a mere re-bodying exercise. While retaining the donor car’s 271bhp V8, the wheelbase was shortened from 2473mm to 2400mm. It also featured a marginally narrower track, front and rear (1400mm at each end compared with 1407mm/1422mm). Much of the platform was cut away and replaced with a tubular semi-spaceframe structure. Unlike a regular Mustang, OSI’s offering featured an independent rear-suspension arrangement, complete with a self-locking ZF diff, along with all-round disc brakes. Riding on knock-off Borrani wire wheels, and bodied in glass fibre, the car’s signature feature was the fold-flat headlight arrangement which foretold the Porsche 928. Inside the Ford Mustang OSI, there was the obligatory mahogany dash, alloy-spoked steering wheel and a mixture of burgundy leather and plaid trim. As it stands, only one car is believed to have been made and its current whereabouts remains a mystery.
