Cadillac OPTIQ data analysis

How Cadillac OPTIQ overall length varies

Across 2 configurations recorded for the 2025 through 2026 Cadillac OPTIQ, overall length runs from 190 inches to 190 inches. The strongest figure belongs to the 2025 Cadillac OPTIQ (OPTIQ 4DR SUV) at 190 inches, and the weakest to the 2026 car (OPTIQ 4DR SUV) at 190 inches — a spread of 0%. The narrow spread means any year of the Cadillac OPTIQ 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 Cadillac OPTIQ is 190 inches, against 190 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 Cadillac OPTIQ data

This page lists every 2025 through 2026 Cadillac OPTIQ record we hold for this measurement — 2 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 Cadillac OPTIQ 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 OPTIQ 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 OPTIQ 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

75.2 in wide (body only, mirrors folded) — about 20.8 in of total clearance, so roughly 10 in per side.

Garage door height

Clears

64.6 in tall — 19.4 in of headroom before roof rails, antennas, or a roof box are added.

Parking space

Fits a standard stall

189.8 in long leaves 26.2 in to spare in an 18 ft space, and 32.8 in of side clearance in a 9 ft one.

Its wheelbase (116.1 in) accounts for about 61% 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.
