"With oil crisis memories starting to fade" Ford needed a V8 in the
Mustang II to return "performance to respectable levels." The engine
bay was re-engineered to accept the 302 cu in (4.9 L) V8 option for
the 1975 model year, with revised hood and header panel. The engine
was limited to a two-barrel carburetor and "net" 140 hp (104 kW; 142
PS). Since Ford's Mexican division never lost the V8, they assisted
in the modifications.
Testing by Road & Track "recorded zero to 96 km/h (60 mph) in 10.5
seconds, and a top speed of 171 km/h (106 mph)." 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
Other than the optional V8 engine, the car underwent minor changes
in 1975. The Ghia received opera windows and a padded vinyl
half-top. In mid-year, a 2.3 L "MPG" model was added, featuring 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.
The Mustang II achieved record sales for 1975, making it the 9th
best selling Mustang of all time, with 199,199 sold.
