Ford Mustang Cobra II 1975

Since the car was never meant to have a V8, it became a scramble to re-engineer the car to reinstate the 302 cu in (4.9 L) V8 option in time for the 1975 model year, but only with a two-barrel carburetor and "net" 140 hp (104 kW). To make the V8 option fit, changes were made to the front fenders, engine bay, and header panel. Since Ford of Mexico never lost the V8, they assisted in the modifications. Although tepid by today's standards, the car's stock 302 performed quite well by 1970s standards. The Mustang II's 302 cu in engine became Ford's first officially designated metric V8 Mustang; it was called the "5.0 L" even though its capacity was 4.94 L. Other than the optional V8 engine, the car underwent minor changes in 1975. The Ghia received opera windows within its vinyl top. In mid-year, a "MPG" model was added to a 2.3 L base models that featured a catalytic converter and a 3.18:1 rear-axle ratio (standard was 3:40:1) to claim EPA-version economy estimates of 23 mpg-US (10 L/100 km/28 mpg-imp) in the city and 34 mpg-US (6.9 L/100 km/41 mpg-imp) on the highway. To underscore fuel efficiency, all base 2.3 L Mustang IIs were called MPG after 1975.
