VIDEO: Watch the Audi RS6 Avant Take on the Audi RS4 Avant

Who doesn’t love a bit of sibling rivalry? In this new video from Auto Bild, we get to see the Audi RS6 Avant take on its much smaller, much less expensive sibling, the Audi RS4 Avant. They go head-to-head on both the road and the track, to see which is faster in a straight line and on a circuit.


Both cars are fast Audi wagons but that’s about where their similarities end. The RS6 Avant uses a 4.0 liter twin-turbocharged V8 with 591 horsepower and 590 lb-ft, while the RS4 uses a twin-turbo V6 with 444 horsepower and 443 lb-ft. The RS4 Avant is much smaller, lighter and less expensive. So can its lighter weight make up for its massive power disadvantage?

During the straight-line drag race, the Audi RS6 Avant was fastest. What’s surprising is how close the two cars were to 62 mph, with the RS6 doing it in 3.4 seconds and the RS4 doing it in 3.6 seconds. Only two tenths between the two, which is pretty good considering the power disparity. However, the lead grew and grew as the speeds increased.


On track is where the cars surprised the most. You expect the RS4 Avant to be better on a circuit, thanks to its smaller size and lower curb weight. However, it was actually the Audi RS6 Avant that was fastest. Not only was it faster but it seemed to handle better as well. The RS4 seemed to understeer a bit more at the limit, which is shocking considering the RS6 has a big, bulky V8 over its nose.

The Audi RS6 Avant was faster than the RS4 on both sets of tires it was tested on. The RS6 was tested with Pirelli P Zero performance tires and Hankook Ventus S1 Evos and it was the fastest on its Hankooks, by a decent margin. While the RS4 was only tested on Pirellis, so we can’t tell if tires would have made a difference. Still, the RS6 Avant dominated on track.


It’s not often that the bigger, heavier car is faster and more capable on track but that seems to be the case with the RS6 and RS4. So we now know who wins that sibling rivalry.
