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, 26 such records for Pontiac alone, model years 1973 to 2009.
One row per generation, not per model year: manufacturers rarely change the body between facelifts, and for Pontiac that means 26 generation rows instead of 26 year-by-year ones. Where a generation offered several body styles, the figures are the base measurements for that generation, which is how the 11 Pontiac entries below are built.
