Audi has debuted the 2027 RS5 performance plug-in hybrid, featuring a new electric torque-vectoring rear differential developed by the company [1].
The vehicle represents a significant shift in Audi's performance strategy by blending traditional internal combustion power with advanced electrification. This transition aims to maintain high-speed capabilities while meeting stricter efficiency standards through a hybrid powertrain.
To showcase the technology, Audi hosted a series of test drives in Saalfelden, Austria, flying journalists from Washington, D.C., to Munich, Germany [1]. The event provided an initial look at how the vehicle handles complex terrain using its new differential system.
Under the hood, the 2027 RS5 utilizes a 2.9-liter twin-turbo V6 engine [2]. This engine produces 510 PS [2]. Complementing the combustion engine is an electric motor capable of 130 kW [2]. Together, these components provide a combined system output of approximately 639 PS [2].
Despite the power gains, the integration of hybrid components adds significant mass to the chassis. The vehicle's claimed weight is 5,200 pounds [3]. This weight increase is a common challenge for performance plug-in hybrids, as batteries and electric motors add bulk that can affect agility.
The new electric torque-vectoring rear differential is designed to mitigate some of these handling challenges. By precisely controlling the power delivered to each rear wheel, Audi aims to improve cornering and stability during high-performance driving [1].
“Combined system output of approximately 639 PS”
The 2027 RS5 signals Audi's attempt to bridge the gap between the era of internal combustion and fully electric vehicles. By utilizing a high-output PHEV system, Audi is testing whether consumers will accept a significant weight increase—over 5,000 pounds—in exchange for the combined performance of a V6 engine and electric motors. The success of the torque-vectoring differential will be critical in determining if the car can maintain the driving dynamics expected of the RS brand.
