Are the engines of Audi RS4 and S4 the same?
2 Answers
Audi RS4 and S4 do not share the same engine. The RS4 is equipped with a 2.9T twin-turbocharged engine, while the S4 uses a 3.0T turbocharged engine. Taking the 2020 Audi RS4 as an example, its body dimensions are: length 4782mm, width 1866mm, height 1437mm, wheelbase 2826mm, fuel tank capacity 58L, luggage compartment capacity 505L, and curb weight 1840kg. The front suspension is a five-link independent suspension, and the rear suspension is also a five-link independent suspension. It is powered by a 2.9T twin-turbocharged engine with a maximum horsepower of 450PS, maximum power of 331kW, maximum torque of 600Nm, and is paired with an 8-speed automatic transmission.
I often get asked whether the Audi RS4 and S4 share the same engine, and honestly, they're quite different. From a powertrain perspective, the S4 typically uses a 3.0-liter V6 turbocharged engine, delivering around 350 horsepower, with smooth acceleration and fuel efficiency, making it ideal for daily driving. The RS4, on the other hand, is far more aggressive, equipped with a 2.9-liter V6 biturbo engine that unleashes over 450 horsepower, delivering an intense push-back sensation the moment you step on the gas, along with a more aggressive exhaust note. This difference stems from Audi's performance strategy: the S series represents an enhanced sporty version, while the RS embodies the ultimate track-focused pursuit. If you're choosing between them, I recommend test-driving first—once you've driven the RS4, you'll understand just how exhilarating its acceleration is, but don't forget its higher fuel consumption and maintenance costs, as well as its more premium parts. In short, the engine differences directly impact driving enjoyment—the RS4 is better suited for hardcore enthusiasts, while the S4 is more practical. Base your decision on your usage scenario; speed demons shouldn't miss the thrill of the RS.
