Interior Floor Carpet / Main Cabin Carpet – 4K8863021D QA5

Original, pressure-formed passenger cabin floor carpet (main floor carpet with integrated factory acoustic insulation and sound-deadening foam), designed for Audi A7 Sportback (4K / 4K8 generation) models produced from 2018 to 2026, including versions with 3.0 V6 TFSI (55 TFSI), 2.0 TFSI, TDI, and S7 and RS7 variants, based on the modular MLBevo longitudinal platform.

Original VAG group interior trim component. Made of high-density needle-punched velour with enhanced resistance to abrasion, moisture, and mechanical soiling, in an elegant, factory-original Black Soul color (VAG trim code: QA5). The underside consists of thick, precisely formed polyurethane foam and bitumen-acoustic mats, which provide factory-standard noise insulation from road and suspension noise and fit perfectly into the floor contours and center tunnel. The carpet features factory cutouts for seat rails, footwell vents, pedals, and center console mounting points.

Fitment guarantee and VIN verification

Each carpet undergoes a thorough inspection of the velour condition and sound-deadening foam integrity, and is cleaned before shipping.

Fitment / installation tip: The initial designation 4K8 is unique to the A7 Sportback body style (as opposed to the A6 Limousine/Avant, designated as 4K0/4K1/4K2). This ensures a perfect fit with the low seat rails, rear seat profile, and A7 console. The three-letter code QA5 indicates the original Soul Black color used in most factory interior configurations. Before purchasing, we recommend comparing the OE number along with the color code on the factory sticker on the underside of the carpet, or verifying it using the vehicle's VIN.
