New Carbon Edition versions of the recently reintroduced Audi RS 4 Avant and RS 5 Coupé are about to turn up the desirability dial for devotees of the latest 450PS Audi Sport stars. The new special editions, which will not be production limited, add motorsport-inspired Carbon Fibre Reinforced Polymer (CFRP) detailing, including a fully exposed CFRP roof in RS 5 versions, as part of a wider package of upgrades that further enhance the appeal of these hallmark models. Both Carbon Edition variants become available today, the RS 4 priced at £71,625 OTR and the RS 5 at £75,400 OTR. The first RS 5 Carbon Edition models will arrive in the UK in December, followed by their RS 4 counterparts in March 2018. Beyond the striking, exposed CFRP roof which is reserved exclusively for the RS 5, both new editions incorporate a Carbon Matt Aluminium Styling Pack adding a CFRP finish for the front spoiler (and the rear in RS 5), sill extensions, a diffuser insert and interior inlays along with CFRP door mirror housings.
