Mercedes-Benz CLS-Class data analysis

How Mercedes-Benz CLS-Class overall length varies

Across 10 configurations recorded for the 2015 through 2018 Mercedes-Benz CLS-Class, overall length runs from 194 inches to 197 inches. The strongest figure belongs to the 2016 Mercedes-Benz CLS-Class (CLS CLASS CLS 63 AMG 4DR SEDAN) at 197 inches, and the weakest to the 2018 car (CLS CLASS CLS 550 4MATIC 4DR SEDAN) at 194 inches — a spread of 1%. The narrow spread means any year of the Mercedes-Benz CLS-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 2018

Average overall length for the 2018 Mercedes-Benz CLS-Class is 196 inches, against 196 inches for the 2017 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 CLS-Class data

This page lists every 2015 through 2018 Mercedes-Benz CLS-Class record we hold for this measurement — 10 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 CLS-Class numbers

The 2015 through 2018 Mercedes-Benz CLS-Class entries here cover the variants CLS CLASS CLS 63 AMG 4DR SEDAN, CLS CLASS CLS 550 4MATIC 4DR SEDAN and CLS CLASS CLS 400 4MATIC 4DR SEDAN. 2016 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 CLS-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 CLS-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 CLS-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

74 in wide (body only, mirrors folded) — about 22 in of total clearance, so roughly 11 in per side.

Garage door height

Clears

55.9 in tall — 28.1 in of headroom before roof rails, antennas, or a roof box are added.

Parking space

Fits a standard stall

196.9 in long leaves 19.2 in to spare in an 18 ft space, and 34 in of side clearance in a 9 ft one.

Size drift: the 2018 Mercedes-Benz CLS-Class is 2 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 (113 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.
