Carbon Fiber Rear Bumper Diffuser for 2011-2014 Audi A7 Sline Sportback

Carbon Fiber Rear Bumper Diffuser for 2011–2014 Audi A7 S Line Sportback (4G, Pre-Facelift)

The Audi A7 Sportback 4G (C7, 2011–2018) is Audi's flagship five-door fastback Sportback — a unique body in Audi's lineup combining a saloon-length wheelbase with a raked fastback roofline and a powered tailgate. The A7's S Line specification includes a distinct rear bumper with a larger lower diffuser section featuring a structured centre channel and twin pseudo-exhaust apertures — a geometry completely different from the A7 Base rear bumper and from the S7's dedicated AMG-style twin-oval exhaust bumper. The A7 4G also received a significant LCI Facelift in 2015 with a revised rear bumper design, making Pre-Facelift (2011–2014) and Facelift (2015–2018) A7 S Line rear bumper diffusers incompatible. This carbon fiber rear bumper diffuser is a replacement-style installation engineered for the A7 4G S Line Pre-Facelift (2011–2014) rear bumper, fitting the S Line's diffuser lower section. 6 kg, screws included, professional installation recommended.

A7 4G Pre-Facelift S Line Rear Bumper — Audi Sport Carbon Diffuser Reference

Audi Sport's accessories programme for the 4G A7 S Line includes carbon rear bumper diffuser elements at the S Line bumper's lower section — factory validation that the A7 S Line's rear bumper diffuser position is the correct Audi Sport carbon aero upgrade location on the 4G Pre-Facelift platform. The A7 S Line Pre-Facelift rear bumper diffuser's structured lower channel — with its centre channel detail and twin apertures — is the primary rear visual differentiator between the A7 S Line and Base variants: a carbon replacement at this position upgrades the most visible rear exterior element on the 4G A7 S Line's rear end from factory plastic to genuine carbon.

A7 Sportback S Line Engine Range Coverage — Pre-Facelift (2011–2014)

This diffuser fits the A7 4G Sportback with S Line rear bumper across the full Pre-Facelift engine range — 3.0 TFSI (300 hp), 3.0 TDI (204/245 hp), 4.0 TFSI biturbo (420 hp, RS7-adjacent), and other A7 engine variants — all sharing the same S Line Pre-Facelift rear bumper diffuser geometry in Quattro all-wheel drive configuration.
