Prototypes for the next-generation Audi S6 and RS 6 have been observed during testing, signaling an upcoming official reveal. The S6 is expected to be the first model in the S line to utilize plug-in hybrid (PHEV) technology, transitioning from traditional V8 engines to a 3.0-liter V6 configuration paired with an electric motor.

Testing has identified both sedan and Avant (station wagon) body styles. The S6 is positioned to offer performance levels between the S5 and the RS5. Additionally, the RS 6 is undergoing updates based on the A6 C9 platform, which will see the return of a four-door sedan alongside the Avant version. These high-performance models are anticipated to arrive in dealerships by early 2027.
