Porsche 911 Specs

Every Porsche 911 generation, measured

One row per generation. Watch the weight column — that is where most of the change happens for the Porsche 911, 1,078 lb of it since 1971, and it is the number that decides fuel use, tyre wear and how far the car takes to stop.

From 1971 to today the 911 gained 13″ of length (8%) and 1,078 lb of weight (48%). A modern compact often outweighs the mid-size car of a generation before.

911 year by year

Measured every model year, not just at generation changes — 56 years on record for the Porsche 911. Small moves inside a generation are facelifts; the jumps are the 6 new platforms below.

Will a 911 fit

The practical question behind every dimensions search, and for a 14.7-foot Porsche 911 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 911 clears the garage by 4.3 ft. We allow a foot of clearance in both — nobody parks to the millimetre.

Against cars of the same length

Compared with 870 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 3,329 lb the Porsche 911 is right on the class average, 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, 56 measured model years for the Porsche 911 between 1971 and 2026.

One row per generation, not per model year: manufacturers rarely change the body between facelifts, and the Porsche 911 fits into 6 rows instead of 56. Where a generation offered several body styles, the figures are the base measurements for that generation of the Porsche 911.
