The body styles were, once again, four-door sedan, two-door hardtop coupé, and five-door station wagon. The C110 was more fussy in its styling than its predecessor, particularly so in wagon form, where unusually for a wagon design, no windows were fitted between the C and D pillars. Its appearance seems to be influenced by the 1970–1975 Citroën SM. The C110 was the first version to return to the round rear tail and brake lights introduced in 1963 albeit with dual units from the previous generation, and the appearance has become a traditional Skyline feature. The styling also influenced a smaller, more affordable two-door coupe, called the Silvia, introduced in 1975. Nissan introduced its emission control technology, primarily consisting of fuel injection on trim packages ending with an "E", using the moniker Nissan NAPS also in 1975. In February 1976, the model was facelifted and became C111 model.
