If you’re ordering a new Audi RS6 Avant, you’ll have a choice of two different suspension options. One of which is its as-standard adaptive air suspension, while the other is an option fixed damper and coil spring setup. Typically, those are reversed, with the fixed suspension being standard and air suspension being optional. However, in the case of the RS6, it’s the fixed damper setup that you want because it’s Audi’s Dynamic Ride Control (DRC) with cross-linked hydraulic dampers.
According to this new long-term review update of the RS6 from Top Gear, a back-to-back comparison between both suspensions indicates that Audi’s DRC is the superior suspension setup
The air suspension isn’t bad, of course. But it’s a tad too soft and comfortable for the sort of car that the Audi RS6 Avant is. The DRC, with its fancy cross-linked suspension (something McLaren has been using on its supercars for a few years now), is tauter, sharper and keeps the car flatter through corners. So it’s the more capable suspension setup and that allows the RS6 to deliver more of its handling potential to the road.
More importantly, it actually transmits more road and steering feel to the driver, as it’s more physically connected to the road. There aren’t air bladders interfering with the driver’s connection to the road below, which makes the Audi RS6 Avant more enjoyable to drive.
As fast and as capable as the RS6 is, there’s no cheating physics — it’s still a very heavy car. Because of that, you’re going to want to know exactly what’s going on underneath you if you’re going to push it hard. While even the DRC won’t transform the luxurious RS6 Avant into a paragon of automotive communication and tactile feedback, it does help enough to be well worth the extra money.
Admittedly, if you want your RS6 to be as comfortable as possible, then the standard air setup is the better choice. For chewing up hundreds of miles, it’s the air suspension you want. However, the DRC doesn’t actually lose much by way of comfort, as it’s still quite plush, but it does offer sharper handling than the air suspension, so it provides a bit better duality. If it’s our money, we’re taking the DRC every time.
