2022 Audi RS3 First Drive: More Is Better


2022 Audi RS3 First Drive: More Is Better

Sometimes, less is more. The updated 2022 Audi RS3 weighs a bit less, and that’s always a good thing when it comes to improving performance. Other times, though, more is more. The new RS3 sedan also wins by addition: More torque and more control over its distribution.

Under the RS3’s nose, Audi found an extra 15 lb-ft of torque and one extra pony hiding out in the ECU of the turbocharged 2.5-liter inline-five  401 hp and 369 lb-ft. Hardly monumental increases, but the previous RS3 wasn’t lacking for power.

What it was lacking was an ideal means of exploiting that power. The old RS3’s Haldex differential and brake-based torque vectoring systems did their best, and they made the car a little ball of fun, but they were imperfect technical solutions. This time out, Audi’s RS department went all the way and designed a proper torque-vectoring rear axle. Dubbed Torque Splitter, it adds variable lockup clutch packs to each axle half shaft, allowing the computer to fully regulate the amount of power going to either rear wheel.

Up to 50 percent of the engine’s power can be shunted rearwards by the center differential, and of that, up to 100 percent can be sent to either rear wheel. Unlike a passive design, there’s no waiting for a wheel to slip before power is transferred across the rear axle. The computer can send all the power to either side any time it feels the need, and don’t think it won’t.
