Cadillac ATS data analysis

How Cadillac ATS overall length varies

Across 32 configurations recorded for the 2015 through 2019 Cadillac ATS, overall length runs from 183 inches to 184 inches. The strongest figure belongs to the 2015 Cadillac ATS (ATS 2DR COUPE 2.0L AWD) at 184 inches, and the weakest to the 2019 car (ATS 4DR SEDAN TURBO/3.6L V6 RWD) at 183 inches — a spread of 1%. The narrow spread means any year of the Cadillac ATS 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 2019

Average overall length for the 2019 Cadillac ATS is 184 inches, against 184 inches for the 2018 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 Cadillac ATS data

This page lists every 2015 through 2019 Cadillac ATS record we hold for this measurement — 32 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 Cadillac ATS numbers

The 2015 through 2019 Cadillac ATS entries here cover the variants ATS 4DR SEDAN TURBO/3.6L V6 RWD, ATS 4DR SEDAN TURBO/3.6L V6 AWD, ATS 2DR COUPE 3.6L RWD, ATS 2DR COUPE 3.6L AWD, ATS 2DR COUPE 2.0L RWD, ATS 2DR COUPE 2.0L AWD and ATS 4DR SEDAN BASE RWD. 2016 is the busiest model year in the record with 7 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 Cadillac ATS 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 Cadillac ATS 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 Cadillac ATS 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

53.9 in tall — 30.1 in of headroom before roof rails, antennas, or a roof box are added.

Parking space

Fits a standard stall

184.3 in long leaves 31.7 in to spare in an 18 ft space, and 35.2 in of side clearance in a 9 ft one.

Size drift: the 2019 Cadillac ATS is 1 in shorter 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 (109.4 in) accounts for about 60% 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.
