A brief misstep by Audi appears to have revealed crucial details about the next-generation Audi RS5 ahead of its official reveal, pointing to a significant mechanical shift for the high-performance model. The slip suggests the upcoming RS5 will adopt a plug-in hybrid powertrain, signaling a major change beneath the surface and marking a first for Audi Sport’s RS lineup.
Although rumors about a hybridized RS5 have circulated for some time, confirmation only emerged after Audi briefly published, and quickly deleted, a LinkedIn post late last week.
The post was captured before it disappeared, and in it the automaker stated, “The new Audi RS 5 is also nearing its debut and will be our first performance plug-in hybrid.”
That single line effectively confirmed what had previously been speculation. Shortly after, Audi doubled down by releasing its first teaser image of the RS5 in Avant form and announcing that the full debut is scheduled for later this month.
Audi has yet to release full technical specifications for the new hybrid system, but the move aligns with the brand’s broader electrification strategy.
The recently updated S5 already employs a mild-hybrid setup, making the transition to a plug-in hybrid RS5 a logical next step. Beyond helping Audi meet increasingly strict Euro 7 emissions regulations, electrification is expected to deliver a notable performance boost and potentially allow for a useful electric-only driving range.
That added capability may come with a downside, however, as plug-in hybrid performance cars often carry a significant weight penalty. The latest BMW M5 PHEV, for example, tips the scales at 5,390 pounds, making it more than 1,000 pounds heavier than the model it replaced.
Audi’s engineers will likely face a similar challenge, as they work to preserve the neutral handling balance seen in the updated S5 while accommodating batteries and electric motors.
Under the hood, current indications suggest the RS5 will not follow the S5’s single-turbo 3.0-liter V6. Instead, it’s widely believed Audi will revive an updated version of the 2.9-liter twin-turbocharged V6 previously used in the RS4.
In standard form, that engine produces 444 horsepower, and when paired with an electric motor, the combined output could climb substantially. Such a setup would give the RS5 a meaningful performance edge while maintaining its V6 character.
If Audi decides to push the envelope further, the new RS5 could even target rivals like the Mercedes-AMG C 63 E Performance, which uses a plug-in hybrid system combining a turbocharged four-cylinder with electric assistance to generate 671 horsepower and 752 lb-ft of torque.
Even that benchmark may be temporary, as AMG has already indicated plans to move away from the four-cylinder hybrid layout in favor of a straight-six for the next-generation C63.
Beyond its electrified drivetrain, the upcoming RS5 is expected to wear its performance intent proudly. Spy shots point to more aggressive front-end styling, pronounced fender flares, and a revised interpretation of Audi’s signature oval exhaust outlets.
Subtlety won’t be the goal here, and it doesn’t need to be. With a plug-in hybrid powertrain and bold new design cues, the next RS5 looks set to redefine what Audi’s compact performance flagship represents in the electrified era.
