Acura RDX data analysis

How Acura RDX overall length varies

Across 17 configurations recorded for the 2015 through 2026 Acura RDX, overall length runs from 183 inches to 188 inches. The strongest figure belongs to the 2022 Acura RDX (RDX A-SPEC 4DR SUV) at 188 inches, and the weakest to the 2018 car (RDX 4DR SUV AWD) at 183 inches — a spread of 2%. The narrow spread means any year of the Acura RDX 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 2026

Average overall length for the 2026 Acura RDX is 188 inches, against 188 inches for the 2025 car — it held flat. A carry-over year like this usually means no powertrain or structural change, so an older example is the cheaper way into the same specification.

How to read this Acura RDX data

This page lists every 2015 through 2026 Acura RDX record we hold for this measurement — 17 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.

Configurations behind these Acura RDX numbers

The 2015 through 2026 Acura RDX entries here cover the variants RDX BASE/TECH 4DR SUV, RDX A-SPEC 4DR SUV, RDX 4DR SUV, RDX 4DR SUV AWD and RDX 4DR SUV AWD/TECH PACKAGE. 2026 is the busiest model year in the record with 2 separate measured configurations, which is why a single quoted overall length figure for that year is rarely the one that matches the car in front of you. Match the row to the exact drivetrain, body style and engine on the window sticker or VIN before relying on the number, and use the comparison links below to see how those same configurations line up against rival models.

Where these Acura RDX 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 Acura RDX 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 Acura RDX 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

74.8 in wide (body only, mirrors folded) — about 21.2 in of total clearance, so roughly 11 in per side.

Garage door height
Clears

66.5 in tall — 17.5 in of headroom before roof rails, antennas, or a roof box are added.

Parking space
Fits a standard stall

187.8 in long leaves 28.2 in to spare in an 18 ft space, and 33.2 in of side clearance in a 9 ft one.

Size drift: the 2026 Acura RDX is 4 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 (108.3 in) accounts for about 58% 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.
