Audi AG has photographed a prototype of a new RS6 sedan, a plug‑in hybrid expected to deliver roughly 720 horsepower.

The reveal matters because it broadens Audi’s RS6 lineup and brings back a sedan version that disappeared after the C7 generation ended in 2011, addressing market demand for a high‑performance sedan.

The spy shots, taken in April 2026, show a sleek four‑door design that Audi plans to move into production for the 2027‑2028 model year — CarScoops said a 2028 launch while TheDrive said a 2027 debut, indicating a possible 2027‑2028 window [1][3].

CarScoops said the upcoming RS6 will use a plug‑in hybrid powertrain that pushes the output to approximately 720 hp, a figure that would place it among the most powerful sedans in its class [1].

Audi’s decision follows a 15‑year period during which the RS6 was offered only as the Avant wagon. The last time a sedan bearing the RS6 badge rolled off the line was in 2011, marking a 15‑year gap that the company now aims to close [2].

For context, the limited‑run 2025 RS6 Avant GT saw only seven examples produced, underscoring the rarity of high‑output RS variants and the significance of expanding the range [4].

"The RS6 sedan has been spied and it's expected to feature a high‑performance plug‑in hybrid system with around 720 hp," said the CarScoops author.

"After 15 years, Audi is finally making an RS6 sedan again," said the MSN Autos writer.

"The model could reach production for the 2027‑2028 model year," said the report.

**What this means** Audi’s RS6 sedan prototype signals the brand’s intent to compete more aggressively in the luxury performance sedan segment, where rivals are adding electrified powertrains. By reviving the sedan body style and pairing it with a high‑output plug‑in hybrid system, Audi may attract buyers seeking both practicality and track‑ready performance, potentially boosting sales in a market that has grown hungry for electrified high‑performance cars.
