Acura RLX data analysis
How Acura RLX overall length varies
Across 7 configurations recorded for the 2015 through 2021 Acura RLX, overall length runs from 196 inches to 198 inches. The strongest figure belongs to the 2018 Acura RLX (RLX 4DR SEDAN AWD HYBRID) at 198 inches, and the weakest to the 2017 car (RLX 4DR SEDAN AWD HYBRID) at 196 inches — a spread of 1%. The narrow spread means any year of the Acura RLX 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 2021
Average overall length for the 2021 Acura RLX is 198 inches, against 198 inches for the 2020 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 RLX data
This page lists every 2015 through 2021 Acura RLX record we hold for this measurement — 7 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 Acura RLX 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 RLX 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 RLX 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.
74.8 in wide (body only, mirrors folded) — about 21.2 in of total clearance, so roughly 11 in per side.
57.5 in tall — 26.5 in of headroom before roof rails, antennas, or a roof box are added.
197.6 in long leaves 18.4 in to spare in an 18 ft space, and 33.2 in of side clearance in a 9 ft one.
Size drift: the 2021 Acura RLX 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 (112.2 in) accounts for about 57% 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.
