The 2015 RS 5 is a driver’s car that attacks and eats up corners like a Great White shark swimming among baitfish. The car is equipped with the Quattro® all-wheel drive system and has plenty of tricks up its sleeve. There’s a torque-vectoring sport differential available, which dramatically increases turning force in corners.
An advanced “crown gear” self-locking center differential can vary the distribution of torque between the front and rear axles, sending up to 70 percent of engine power to the front wheels or 85 percent to the rear when needed. The crown gear diff works in conjunction with a stability control system that can apply brake pressure to the inside wheels in turns to minimize understeer. An active rear differential can transfer power between the rear wheels to help achieve the same end. And straight-line speed? It’s all there too, at a quoted 4.5 seconds 0-60 mph.
The RS 5 is in a class with the Mercedes-Benz C63 AMG Coupe, the BMW M4, and the Cadillac CTS-V coupe, but unlike many competitors that use forced induction motors, the RS 5 has a naturally aspirated 4.2-liter that produces 450 horsepower and revs up to 8,300 rpm – so at speed, you may blink and miss it, but you’ll always hear it coming first.
