Once again, no change in the distinctive recessed headlamps and rectangular parking lights that were still under the headlamps and below the bumper. Front fenders still the reflector lenses at the rear of the headlamps. The low, wide grille remained, and the hood still had its bulge. The small round insignia remained above the grille. Early 1974 US 260Z models had bumpers that resembled those of the earlier 240Z, though increased slightly in size, pushed away from the body somewhat, and wearing black rubber bumper guards rather than the previous chrome bumper guards with rubber strips. The early cars still had the front turn signals located below the bumpers. Late 1974 U.S. 260Z models had the heavier bumpers that would be used on the 1975-76 280Z. These late cars had the front turn signals relocated to the outer edges of the front grill, above the bumper.

This 2+2 model sat on a 11.80″ longer wheelbase with noticably larger opening quarter panel windows and an extended and more notched roofline. The 2+2was for the most part, identical inside aside from the rear seat, but did receive a carpeted transmission tunnel instead of the quilted vinyl material used on the two-seater. The rear side windows on the 2+2 could open as they were push-out, done to give ventilation for rear seat occupants.

The single-overhead cam six-cylinder engine was increased to 2,565 cc (156.5 CID) and was retuned to meet US emissions standards, but it now only made 139 HP. The four-speed manual or three-speed automatic transmissions were unchanged. The four-wheel independent suspension, consisting of coil springs and MacPherson struts and front disc and rear drum brakes were not altered. The chassis was redesigned with additional stiffness because the chassis rails which were larger and extended further back than previous models. A rear sway bar was added.

Oil pressure, water temperature, fuel and ammeter gauges were recessed in a padded and formed dash. A large speedometer with trip odometer, and a tachometer, sat directly ahead of the driver. The climate controls were more sensibly laid out and easier to work, and those cars with air conditioning now had the A/C system integrated into the main climate control panel. The deep cushioned vinyl bucket seats with built-in headrests adjusted horizontally and vertically and reclined up to 10 degrees. A new console, new seat trim and door panels were featured.

Standard 240Z equipment included radial tires, a radio, clock, steering lock, collapsible steering wheel, three anchor seat belts, backup lights, a wood steering wheel and gearshift knob, front/rear bumper bars, console box, door armrest, driver footrest, glove box with lock, windshield and rear-window drip moldings, and coat hangers.
