Porsche Boxster data analysis

How Porsche Boxster overall length varies

Across 2 configurations recorded for the 2015 Porsche Boxster, overall length runs from 172 inches to 173 inches. The strongest figure belongs to the 2015 Porsche Boxster (BOXSTER GTS 2DR CONVERTIBLE) at 173 inches, and the weakest to the 2015 car (BOXSTER BASE/S 2DR CONVERTIBLE) at 172 inches — a spread of 1%. The narrow spread means any year of the Porsche Boxster in this table behaves much like the others, so you can shop on price, condition and mileage rather than chasing a particular model year.

How to read this Porsche Boxster data

This page lists every 2015 Porsche Boxster record we hold for this measurement — 2 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 Boxster 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 Boxster 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 Boxster 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

70.9 in wide (body only, mirrors folded) — about 25.1 in of total clearance, so roughly 13 in per side.

Garage door height
Clears

50.4 in tall — 33.6 in of headroom before roof rails, antennas, or a roof box are added.

Parking space
Fits a standard stall

173.2 in long leaves 42.8 in to spare in an 18 ft space, and 37.1 in of side clearance in a 9 ft one.

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.
