Audi RS 3 data analysis

How Audi RS 3 overall length varies

Across 7 configurations recorded for the 2017 through 2026 Audi RS 3, overall length runs from 176 inches to 178 inches. The strongest figure belongs to the 2025 Audi RS 3 (RS 3 4DR SEDAN) at 178 inches, and the weakest to the 2021 car (RS3 SEDAN) at 176 inches — a spread of 1%. The narrow spread means any year of the Audi RS 3 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 Audi RS 3 is 178 inches, against 178 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 Audi RS 3 data

This page lists every 2017 through 2026 Audi RS 3 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 Audi RS 3 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 Audi RS 3 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 Audi RS 3 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

72.8 in wide (body only, mirrors folded) — about 23.2 in of total clearance, so roughly 12 in per side.

Garage door height

Clears

55.5 in tall — 28.5 in of headroom before roof rails, antennas, or a roof box are added.

Parking space

Fits a standard stall

178.3 in long leaves 37.7 in to spare in an 18 ft space, and 35.2 in of side clearance in a 9 ft one.

Size drift: the 2026 Audi RS 3 is 2 in longer than the 2017 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 (103.5 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.
