Power comes from a twin-turbocharged, hybridized 4.0-liter V8 that produces 591 horsepower (441 kilowatts) and 590 pound-feet (800 Newton-meters) of torque. That makes the RS6 Avant the most powerful iteration to date (before package options, of course). The Audi's electrified oomph travels through an eight-speed Tiptronic transmission to all four wheels via a full-time Quattro all-wheel-drive system. To 62 miles per hour (100 kilometers per hour) it takes the RS6 Avant a blistering 3.6 seconds. Top is limited to 155 mph (250 kmh).
