=====S8 Plus 4.0 TFSI Quattro (2016)=====
Based on the same chassis and underpinnings as the D4 S8, the D4 S8 Plus became the sole option for ordering the S8-variant of the Audi A8 line in the US, in the 2016 and 2017 model years. The S8 Plus was dialed up to {{Convert|605|hp|kW|abbr=on}} out of the same powerplant as the previous S8, by remapping the turbo boost and fuel delivery of the engine. Additionally, the Carbon Ceramic braking system is standard on the S8 Plus in some markets. The vast majority of options on the S8 Plus were identical to the previous S8; however, it had darkened tail lights standard, and the option for adding carbon fiber styling elements such as the mirror caps, rear lip spoiler, rear diffuser, and front lip. Different markets had different standard packages combining elements of the external carbon package, the dynamic package and the interior design package. A highly-optioned build of the S8 Plus would outprice the nominally higher-end A8 L W12 whose production ceased after the 2018 model year.<ref>{{Cite web|url=https://www.autoblog.com/2018/03/19/audi-a8-w12-engine/|title=A8 is the last Audi to get the W12 engine, exclusive of Bentley|website=Autoblog|date=19 March 2018 }}</ref> Unlike the regular S8 which was built by Audi on the regular assembly line alongside other A8 variants, the S8 Plus was built by Audi Sport (formerly Quattro GmbH) and has a VIN that starts with WUA to identify it.<ref>{{cite web|url=https://www.caranddriver.com/reviews/a30000920/2020-audi-s8-drive/|title = 2020 Audi S8 is Not Meant for Chauffeurs|date = 27 November 2019}}</ref>
