Pontiac Grand Am Specs

Every Pontiac Grand Am generation, measured

One row per generation. Watch the weight column — that is where most of the change happens for the Pontiac Grand Am, -1,067 lb of it since 1973, and it is the number that decides fuel use, tyre wear and how far the car takes to stop.

Grand Am year by year

Measured every model year, not just at generation changes — 23 years on record for the Pontiac Grand Am. Small moves inside a generation are facelifts; the jumps are the 4 new platforms below.

Will a Grand Am fit

The practical question behind every dimensions search, and for a 15.5-foot Pontiac Grand Am it has a straight answer. A single-car garage in the US is typically 20 feet deep and a street parking space about 18, so the Grand Am clears the garage by 3.5 ft. We allow a foot of clearance in both — nobody parks to the millimetre.

Against cars of the same length

Compared with 1,030 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. At 3,082 lb the Pontiac Grand Am is 591 lb lighter than typical for its size, which generally shows up as fuel economy and stopping distance.

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, 23 measured model years for the Pontiac Grand Am between 1973 and 2005.

One row per generation, not per model year: manufacturers rarely change the body between facelifts, and the Pontiac Grand Am fits into 4 rows instead of 23. Where a generation offered several body styles, the figures are the base measurements for that generation of the Pontiac Grand Am.
