Porsche Cayman data analysis

How Porsche Cayman overall length varies

Across 5 configurations recorded for the 2015 through 2016 Porsche Cayman, overall length runs from 172 inches to 175 inches. The strongest figure belongs to the 2016 Porsche Cayman (CAYMAN GT4 2DR COUPE RWD) at 175 inches, and the weakest to the 2016 car (CAYMAN BASE/S 2DR COUPE RWD) at 172 inches — a spread of 1%. The narrow spread means any year of the Porsche Cayman in this table behaves much like the others, so you can shop on price, condition and mileage rather than chasing a particular model year.

What changed for 2016

Average overall length for the 2016 Porsche Cayman is 173 inches, against 173 inches for the 2015 car — it rose by 0.7 inches. That is a real improvement, and it is the kind of change worth paying the newer-year premium for if this figure drives your decision.

How to read this Porsche Cayman data

This page lists every 2015 through 2016 Porsche Cayman record we hold for this measurement — 5 rows in total, one per configuration and model year rather than a single headline figure. Figures are published as the source agency records them: we do not round, average or interpolate missing years, and a year that is absent from the table is a year with no published measurement rather than a zero. Where a manufacturer offered several drivetrains or body styles in the same year, each appears on its own row, because those variants rarely share the same numbers.

Where these Porsche Cayman figures come from

Every value on this page is loaded from federal open data — EPA fuel economy submissions, NHTSA vehicle and crash-test records, and manufacturer specification filings — rather than dealer listings or copied editorial content. The Porsche Cayman record refreshes as the agencies publish, which typically means new model-year rows appear in the autumn and crash-test results follow through the model year as vehicles are tested. Because certification data is filed per configuration, treat any single headline number for this vehicle with caution: the figure that applies to a specific car depends on its engine, drivetrain, body style and model year, all of which are listed separately above. If a number here disagrees with a brochure, the brochure is usually quoting the best available configuration rather than the one being sold.

Will the Porsche Cayman fit your garage and parking space?

Measured against a standard single garage door (8 ft wide, 7 ft tall, 20 ft deep stall) and a standard US surface parking space (9 ft x 18 ft). Measure your own opening before buying — older garages are frequently narrower.

Garage door width
Fits

71.7 in wide (body only, mirrors folded) — about 24.3 in of total clearance, so roughly 12 in per side.

Garage door height
Clears

50.8 in tall — 33.2 in of headroom before roof rails, antennas, or a roof box are added.

Parking space
Fits a standard stall

174.8 in long leaves 41.2 in to spare in an 18 ft space, and 36.3 in of side clearance in a 9 ft one.

Size drift: the 2016 Porsche Cayman is 1 in longer than the 2015 car in our records. If you are replacing an older example with a newer one, check the garage clearance again rather than assuming the outgoing car's footprint carries over.

Its wheelbase (97.6 in) accounts for about 56% of overall length. A higher share generally means shorter overhangs — better approach and departure clearance on driveways and ramps, and more cabin space for the same parking footprint.
