Known as the “most changed” Chevrolet of the year, the 1975 Nova entered its fourth generation smack dab in the middle of the 1970s. Though the car maintained a similar look to its past generation models, the Nova now had more of a European flare.
Maintaining its 111-inch wheelbase, the 1975 Nova received a larger front stabilizer bar and saw an increase of 1.5-inches in its front tread.
Steel-belted radial tires and front disc brakes were now standard on the model, in addition to a new front-steer and revised subframe setup, which is very similar to that of the 1971-1980 F-body cars (Camaro/Firebird). In fact, every front end component from the X-body Nova can be interchanged with those on the second-generation F-body cars.
The rear suspension for the Nova was carried over to the 1975 model from the third-generation cars.
Inside, the new Novas featured cut-pile carpeting, once reserved for Custom Series Novas, redesigned front arm rests, and a new speedometer with larger script.
Thrusting the Nova into the luxury car market was the top-of-the-line Luxury Nova, or LN. Wide-back reclining front seats, a day/night mirror, electric clock, map pockets and additional sound-deadening insulation are a number of upgrades the LN model featured.
The SS option was also available on the 1975 Nova model, although this upgrade merely added Rally wheels, a blacked out grille and SS emblems.
