Mercedes-Benz GLA-Class data analysis

How Mercedes-Benz GLA-Class overall length varies

Across 26 configurations recorded for the 2015 through 2026 Mercedes-Benz GLA-Class, overall length runs from 174 inches to 175 inches. The strongest figure belongs to the 2015 Mercedes-Benz GLA-Class (GLA CLASS GLA 45 AMG 4MATIC 4DR SUV AWD) at 175 inches, and the weakest to the 2026 car (GLA CLASS GLA 250 4MATIC 4DR SUV AWD) at 174 inches — a spread of 1%. The narrow spread means any year of the Mercedes-Benz GLA-Class 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 Mercedes-Benz GLA-Class is 174 inches, against 174 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 Mercedes-Benz GLA-Class data

This page lists every 2015 through 2026 Mercedes-Benz GLA-Class record we hold for this measurement — 26 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 Mercedes-Benz GLA-Class numbers

The 2015 through 2026 Mercedes-Benz GLA-Class entries here cover the variants GLA CLASS GLA 250 4MATIC 4DR SUV AWD, GLA CLASS AMG 35 4MATIC 4DR SUV AWD, GLA CLASS AMG 45 4MATIC 4DR SUV AWD and GLA CLASS GLA 45 AMG 4MATIC 4DR SUV AWD. 2023 is the busiest model year in the record with 3 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 Mercedes-Benz GLA-Class 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 Mercedes-Benz GLA-Class 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 Mercedes-Benz GLA-Class 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 in wide (body only, mirrors folded) — about 24 in of total clearance, so roughly 12 in per side.

Garage door height
Clears

63.4 in tall — 20.6 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 in of side clearance in a 9 ft one.

Its wheelbase (107.5 in) accounts for about 62% 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.
