There really is only one true competitor to the Audi RS6 Avant — the Mercedes-AMG E63 S Wagon. It’s the only other five-door, 600-horsepower, midsize wagon in the segment and, fortunately for us as customers, both cars are absolutely incredible. But which one is faster? In this new video from Cars.co.za, we get to see a drag race between both cars (although, the AMG in this race is actually a sedan).
On paper, the Mercedes-AMG E63 S Wagon has the advantage. Both cars pack 4.0 liter twin-turbocharged V8s but the AMG has more power, with 603 horsepower and 627 lb-ft of torque. While the Audi RS6 Avant has 591 horsepower and 590 lb-ft. Both have slick-shifting automatic transmissions and all-wheel drive but Audi RS cars typically tend to launch better than their rivals, so it’s interesting to see which car wins the drag race.
Off the line, the Audi RS6 Avant jumps the AMG, gaining a very early lead. With similar power and weight figures, you’d expect the RS6 to be able to hold its lead but it simply can’t. The AMG is just so powerful, it eventually takes the lead, right before they both cross the line. So the AMG wins in the quarter-mile but the Audi RS6 might win stop-light drag-races in the real world.
After the standing-start drag race, they put both cars in a rolling drag race, from 30 km/h, to see which is faster without the benefits of launch control. Typically, this is where Audi Sport models struggle, as incredible traction off the line is what helps Audis move so quickly. And that’s exactly the case here, as the AMG simply walks away from the RS6 in the rolling drag race.
It would be interesting to see which car is better to drive on a twisty road, to better evaluate which performance wagon (or sedan) is worth getting. However, one thing’s for certain — if you want outright speed, the AMG is faster.
