It’s hard to believe that it took 19 Lightning Lap events before a station wagon placed its rubber on southern Virginia’s hallowed tarmac for our test. But here we are now with not one but two boss wagons ready to leave their treadmarks on the all-time list.
The 621-hp twin-turbocharged V-8 powering the RS6 Avant Performance pushes Audi’s anti-SUV to 151.1 mph on the Front Straight before the driver stands on the optional carbon-ceramic brakes, whose 17.3-inch front rotors are so large that they may be capable of intercepting intergalactic radio waves. With the 10-piston front calipers at full squeeze, the wagon’s nose dives and its tail wags into Turn 1, where the Continental SportContact 7 tires hang on at 1.00 g.
The steering has a positive and direct action, but the standard air springs, even in their lowest setting, allow copious amounts of body roll as the lateral g’s increase. Though the RS6 might look cool lifting its inside front wheel while exiting Oak Tree, that doesn’t benefit the lap time. In the Infield, there’s plenty of sawing at the wheel, and timing the side-to-side load transfer to work with you and not against you takes concentration and planning. And while the leather seat is likely supremely comfortable at 190-mph autobahn speeds, the minimal side bolstering had us engaging our abs and using our knees to remain upright. The RS6 works the core.
The RS6 with a tighter bod is the one on steel springs. That suspension is sportier and adds Dynamic Ride Control (DRC), which uses hydraulics to combat body pitch and roll. Alas, our car didn’t have the racier suspension. It’d be interesting to see how much quicker a DRC-equipped RS6 could lap. Maybe next year.
Even so, the RS6 Avant’s 2:55.5 dance around VIR’s ballroom is 0.6 second quicker than an Audi R8 V10 Plus’s. Beating a 602-hp mid-engine two-seater with a wagon that can hold five, plus a golden retriever, is deeply awesome. But there’s a wagon that went even faster.
The Heat Is On
Alcon temperature-indicator strips are used in racing to track brake-caliper temperature. Since VIR punishes braking systems, we applied the strips to the front calipers of some entrants to see how hot things get.
The hottest calipers belonged to two very different cars: the VW Golf R and the Audi RS6 Avant wagon, both of which reached 330 degrees. The 3369-pound Golf R relies on dual-piston front calipers clamping 14.1-inch iron rotors, while the 4846-pound RS6 uses massive 10-piston calipers and 17.3-inch carbon-ceramics, the largest brake rotors in this year’s field.
Sports cars designed for track abuse ran much cooler. The Corvette ZR1 and the 911 GT3 ran hard for three days without heating the calipers enough to register on the strip, which starts at 250 degrees. The same was true of the Audi RS e-tron GT’s 10-piston front calipers. The Audi’s lapping schedule—essentially one hot lap at a time to maximize battery performance—likely kept them cool. —Austin Irwin
