In 1973 Chevrolet once again reworked the Nova to introduce a hatchback body style and restyled the front and rear end. Due to the new government mandates Chevrolet had to redesign the front and rear bumpers to increase the size and strength. This was in order to comply with new automotive safety standards. A new grille with crosshatch inserts and parking lights located inside of the headlights were also added. Every Nova in 1973 also received side guard door beams, additional sound insulation, and better flow-through ventilation.
