I drove my friend's RS4 Avant, and that 2.9-liter V6 twin-turbo engine is truly addictive. With 450 horsepower pushing this wagon, the moment you step on the throttle feels like being catapulted forward. What's most special is its power delivery characteristics: the turbos kick in at low RPMs, completely unlike the laggy feel of older turbocharged cars. I specifically looked it up—this engine, codenamed EA839, shares technology with the Porsche Panamera. Its direct injection and twin-scroll turbo design make it both ferocious and refined. In stock form, it can hit 0-100 km/h in just 4.1 seconds, and the exhaust backfire sounds like a symphony when you roll down the windows in a tunnel.
