Ultimate Family Hauler: Audi RS 6 Avant performance vs RS Q8
Suspension & Driving Dynamics
The RS 6 Avant features two available suspensions. The RS adaptive air suspension uses computer-controlled air shocks to adjust damping and ride height. For example, above 74 mph, the car lowers itself 10mm. Opt for the Dynamic Plus Package with its stiffer air springs, and you can go up to 190 mph. The RS sport suspension plus with Dynamic Ride Control (DRC) combines “steel springs and three-way adjustable dampers.” There are no electronics involved, but the dampers’ hydraulic fluid reservoirs are connected diagonally via a central valve. That is, the front-left connects to rear-right, and vice-versa. This setup forces additional fluid to wherever extra damping is needed, keeping the vehicle stable.
The RS Q8 also features standard adaptive air suspension. But this version offers much more versatility in its height adjustment, with 90mm (3.5 inches) of total travel between its highest and lowest settings. For example, up to 18.6 mph, you can raise the RS Q8 50mm above Normal for Off-Road mode. And, above roughly 100 mph, the RS Q8 automatically lowers itself 40mm versus Normal. There’s no sport suspension option like the RS 6, but Audi does offer an optional electromechanical roll stabilization, which runs off the SUV’s mild hybrid system, for added stability.
Generally speaking, they’re both stunning driver-tuned vehicles that feel almost like sports cars despite their weight. True, those with more track experience know that heavier Audis struggle with understeer at the limit. But for most situations — street, highway, and canyon driving — these two RS Audi models are exceptionally nimble. Again, especially for vehicles tipping the scales at, and over, 2.5 tons.
In this Audi RS 6 Avant performance vs RS Q8 category, the RS 6 takes the win because it weighs less and sits lower to the ground. Dynamically speaking, it is more capable and fluid and fun to drive. The RS Q8 is no slouch mind you, but it can feel downright sloppy in the wrong mode, which the RS 6 never does.
Worth noting that we found also the SUV to be slightly more comfortable than our last RS 6 Avant press loaner. But that’s presumably because RS 6’s optional RS sport suspension plus is a touch harsher when compared to the air ride system. Driving both the RS 6 and RS Q8 with the air ride setup and comfort levels will both be excellent.
