The fifth car sold as an A6, on sale from 2018 to 2025, and the first generation where every engine (four-cylinder to the RS6’s twin-turbo V8) comes with at least 48-volt mild-hybrid assistance as standard, plug-in hybrid TFSI e variants further up the range.[1] It followed the C7 onto Audi’s MLB Evo platform, shared with the A7, A8 and Q7 family.
The trim recorded here, the 45 TFSI quattro, is a mainstream turbocharged four-cylinder rather than the S6/RS6 performance flagships or the plug-in hybrid TFSI e variants also sold on this platform. Wikipedia’s C8 section gives no kerb weight, unlike the C4’s infobox, so that figure is left out here rather than estimated from a different market or trim.
