At the moment, Audi lacks a flagship performance station wagon. The twin-turbo V8-powered RS6 wrapped up with the 2026 model year, and in America, that was the last Audi wagon available at all. In Europe, buyers can still get A4 and A6 wagons, plus S versions. The good news is the hot wagon drought should be short, as Audi has both a traditional RS6 coming, along with some sort of electric equivalent, for a two-pronged defense against the M5 Touring.
Thanks to one of our spy photographers, we’re getting another look at the electric one, which looks as good as ever, but still has us wondering about its name.

From the front, it’s immediately apparent this wagon is based on the electric A6 and S6 E-Tron Avant because of the split headlight arrays and closed off main grille. It differs from the S6 in the lower bumper area with larger outboard intakes which are angled to match the center intake. It has a prominent lower spoiler, too.

Something new to this prototype is the set of wheels, which are like a set we saw on a Sportback prototype, but this time with aluminum highlights that look production-ready. They’re quite large, and really pop against the low, long, hunkered-down wagon body, it’s just a shame we can’t see any size specs on the tires.

We at least know the wheels and tires should be significantly wider than what you’ll get on the S6, which can be up to 245-mm wide at the front and 275-mm wide at the rear. We know this because the fenders are visibly wider, with the front ones featuring heat-extracting vents, and the side skirts are deeper to match the front spoiler.

The tail of this hot electric wagon is the most similar to the regular S6. The hatch, lights and most of the bumper look about the same, but the bumper does have a more prominent diffuser section, and the rear spoiler is larger with longer outboard sections.

We haven’t talked about a name for this yet because that’s still up in the air. We’ve heard from our spy photographers that it may end up being called the S6 E-Tron Performance Avant, rather than RS6 E-Tron. From the outside, it looks different enough that we would expect some major performance increases worthy of RS badging, plus Audi has had RS-badged EVs already. Maybe Audi doesn’t feel like it’s quite earned it, or that it’s reserving it for the combustion RS6.

While we don’t know how much more potent it will be than the S6 E-Tron, we do at least have that as a bit of a benchmark. So this wagon will have more than 543 horsepower and go from 0–60 mph in less than 3.7 seconds. It should also have a battery pack with an 800-volt architecture supporting up to 270-kW DC fast charging. Top speed will also likely be above the S6’s 149 mph.

CarBuzz Insight – Why This Matters:
We have one other major unanswered question about this electric Audi wagon besides the name and the performance: will we get the wagon. We don’t get either the A6 or S6 E-Tron Avant right now, which makes it seem like this hotter version would be unlikely. However, Audi gave the US the RS6 only in wagon form. Audi isn’t the only one to bring wagons Stateside exclusively in performance form, such BMW with the M5 Touring.
So, there’s a legitimate chance that we could see this electric wagon in America, and it could be a unique and exciting offering while options like the M5 still use an engine.
