Audi is set to revive the RS6 sedan, a model that has been absent for 15 years, with the last two generations exclusively offered as Avants. Spy shots reveal a prototype undergoing testing near the Nürburgring, showcasing an aggressive design and hinting at a powerful, possibly hybrid, powertrain.

Key Takeaways

The RS6 sedan is making a comeback after a 15-year hiatus.
The prototype features aggressive styling cues, including large air intakes and a distinctive grille.
A high-performance plug-in hybrid system, potentially with around 720 hp, is rumored for the new model.

A Sedan's Return

After a significant absence, the Audi RS6 sedan is back in development, with a prototype recently spotted testing. This marks the return of the four-door performance variant, which last graced the C7 generation before exiting production in 2011. The new model aims to directly challenge rivals like the BMW M5.

Aggressive Design Language

The spied prototype sports a decidedly aggressive aesthetic. It features a unique diamond mesh grille, substantial air intakes, and a front splitter. Vertical fender vents, sportier side skirts, large wheels, and a high-performance braking system further emphasize its performance credentials. The rear is characterized by a massive dual exhaust system, a new spoiler, and a sportier bumper.

Interior Expectations

While interior details are scarce, the production RS6 sedan is expected to adopt a modern cabin. This will likely include a digital instrument cluster, a large infotainment display, and potentially a front passenger display, mirroring the technology found in the regular A6 lineup. Expect sporty touches like a flat-bottom steering wheel, carbon fiber trim, and performance-oriented seating.

Powertrain Speculation

The powertrain for the new RS6 sedan remains a subject of speculation. However, Audi's recent introduction of the RS5's plug-in hybrid system offers a potential glimpse. This system combines a twin-turbo 2.9-liter V6 with a 25.9 kWh battery, producing 630 hp and enabling rapid acceleration. Rumors suggest the RS6 could feature a more potent plug-in hybrid setup, possibly utilizing a twin-turbo 4.0-liter V8, with an estimated output of around 720 hp. Quattro all-wheel drive and advanced torque-vectoring systems are also anticipated.
