Chevrolet Impala data analysis

How Chevrolet Impala overall length varies

Across 14 configurations recorded for the 2015 through 2020 Chevrolet Impala, overall length runs from 200 inches to 201 inches. The strongest figure belongs to the 2015 Chevrolet Impala (IMPALA 4DR SEDAN 2.5L LS/LT/LTZ/2.4ECO) at 201 inches, and the weakest to the 2016 car (IMPALA LIMITED 4DR SEDAN FWD) at 200 inches — a spread of 0%. The narrow spread means any year of the Chevrolet Impala 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 2020

Average overall length for the 2020 Chevrolet Impala is 201 inches, against 201 inches for the 2019 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 Chevrolet Impala data

This page lists every 2015 through 2020 Chevrolet Impala record we hold for this measurement — 14 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 Chevrolet Impala numbers

The 2015 through 2020 Chevrolet Impala entries here cover the variants IMPALA 4DR SEDAN 3.6L LT/LTZ, IMPALA 4DR SEDAN 2.5L LS/LT/LTZ/2.4ECO and IMPALA LIMITED 4DR SEDAN FWD. 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 Chevrolet Impala 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 Chevrolet Impala 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 Chevrolet Impala 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

59.1 in tall — 24.9 in of headroom before roof rails, antennas, or a roof box are added.

Parking space

Fits a standard stall

201.2 in long leaves 14.8 in to spare in an 18 ft space, and 35.2 in of side clearance in a 9 ft one.

Its wheelbase (111.8 in) accounts for about 56% 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.
