How we measure
Dimensions come from NHTSA vPIC and Transport Canada vehicle records — manufacturer-declared figures, held in metric and converted to inches and pounds for display, 39 such records for Infiniti alone, model years 1990 to 2022.
One row per generation, not per model year: manufacturers rarely change the body between facelifts, and for Infiniti that means 39 generation rows instead of 39 year-by-year ones. Where a generation offered several body styles, the figures are the base measurements for that generation, which is how the 30 Infiniti entries below are built.
