Every Infiniti G20 generation, measured

One row per generation. Watch the weight column — that is where most of the change happens, and it is the number that decides fuel use, tyre wear and how far the car takes to stop.

From 1991 to today the G20 gained 2.4″ of length (1%) and 192 lb of weight (7%). A modern compact often outweighs the mid-size car of a generation before.

G20 year by year

Measured every model year, not just at generation changes — 10 years on record. Small moves inside a generation are facelifts; the jumps are new platforms.

Will a G20 fit

The practical question behind every dimensions search. A single-car garage in the US is typically 20 feet deep; a street parking space is about 18. We allow a foot of clearance in both — nobody parks to the millimetre.

Against cars of the same length

Compared with 890 vehicles within ten inches of the same length — a fair proxy for «cars of this size», regardless of what the marketing calls them.

A longer wheelbase for the same overall length means shorter overhangs — usually more cabin space and a steadier ride. Lighter than typical for its size generally means better fuel economy and shorter stopping distances.

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.

One row per generation, not per model year: manufacturers rarely change the body between facelifts, and a table of forty near-identical rows helps nobody. Where a generation offered several body styles, the figures are the base measurements for that generation.
