2026 Audi RS6 Avant Road Test and Review

“That’s quite a car you have out there,” my neighbor told me. 

She could have been talking about the 2026 Audi RS6 Avant. It’s a 621-horsepower luxury performance machine. It starts at $130,700, and my test car came to $158,865. It’s definitely quite a car. 

But my neighbor didn’t mean the RS6. She meant the other car I was testing that week – a compact Kia K4. The Audi had more than 3 times the Kia’s horsepower, and it cost 5 times as much. But the Kia wore a bold Sparkling Yellow paint job, and its headlights and taillights dipped and bobbed every which way. The Audi was a white station wagon with simpler styling cues. It was easy to miss. 

This under-the-radar attitude is key to the RS6 Avant’s appeal. Someone in the know will spot its giant wheels and big dual exhaust tips. But ordinary folks won’t stare – unless you floor the throttle, and its V8 engine roars you to 60 mph in 3.3 seconds. By then, they’re left wondering what they just saw. 

If you’re looking for an elite performance machine that doesn’t scream “I’m fast” like a sports coupe or stand tall like a high-speed SUV, the 2026 Audi RS6 Avant could be the high-speed, family-friendly ride for you. Keep reading our full review as we go through all the details. 

V8 Performance

Today, it’s not hard to find crazy-fast family cars. It’s just that most of them are electric. That’s great if you’re interested in saving money on fuel or reducing your tailpipe emissions. But if you can’t easily recharge one, or you want your fast car to sound fast, the Audi RS6 comes by its speed the old-fashioned way.

Every RS6 Avant has a 4.0-liter twin-turbo V8 making 621 horsepower and 627 lb-ft of torque. It purrs when you’re cruising gently. But if you stab the throttle, it wakes up in a hurry with a melodic roar and a thrust that slams you back into your seat. My 7-year-old, no stranger to fast cars, caught her breath as we leaped down a short merge lane to find a gap in the traffic. Even the eight-speed conventional automatic transmission was briefly caught flat-footed when I went from rolling at about 10 mph to a sudden full throttle, but it has no trouble once it understands the new assignment. Audi’s Quattro AWD system helps send power to all four wheels to maintain traction.

Now, we know you don’t buy a $131,000, 621-horsepower V8-powered car because you’re expecting to save money at the gas pump. But just for the record, the RS6 Avant gets an EPA-estimated 14 mpg in the city, 21 mpg on the highway, and 16 mpg combined. Only a handful of cars sold in the U.S. use more gasoline. And by daring to drink so much without being a pickup truck or SUV, the RS6 is even subject to a $1,300 federal gas-guzzler tax. At least we edged out that number during our test – hitting an ever-so-slightly thriftier 17 mpg over a week of mixed driving.

Low Center of Gravity

Most of today’s high-speed family cars are SUVs. There’s no shortage of luxury SUVs from BMW’s M division, Mercedes’ AMG, and Audi’s own S and RS. You can get the RS6 Avant’s same engine (though tuned to “just” 500 hp) in the seven-passenger SQ7 crossover. And the five-seat RSQ8 dials it up to 631 hp – a nudge more than the RS6. 

But a station wagon rides lower. That’s great for drivers who prefer a lower seating position. And it also benefits the RS6 Avant’s center of gravity. Road-hugging proportions mean it needs less wizardry to stay steady and stable while changing direction at high speeds. And the RS6 Avant does so with great eagerness. 

We loved the RS6’s taut, precise steering. This isn’t a numb, impersonal, goal-oriented rudder like some performance cars. Audi lets the driver feel what’s going on, and it lets the driver summon instant responses. But the RS6 doesn’t make you labor when you’re driving at low speeds. The steering lightens up easily and naturally when you’re, say, negotiating into a parking space. The RS6 Avant’s four-wheel steering helps it in both high-speed cornering and low-speed maneuvering, too. 

The RS6’s adaptive air suspension also adjusts to either take the edge off bumps or hunker down to deliver maximum performance. Or you can get the optional Sport Suspension Plus for higher handling limits and steel springs. Neither suspension makes the RS6 Avant exactly cushy, not with its performance focus and our test car’s 22-inch wheels. But it can be quite civilized when needed, especially with the air suspension. Whichever one you choose, selectable driving modes let you adjust both the suspension and the powertrain.

Subtly Muscular Presence

As we mentioned, the 2026 Audi RS6 Avant doesn’t scream “look at me” from across a parking lot. But if you do pay attention, you’ll notice it’s no ordinary A6 Allroad mid-size wagon. The RS6 Avant’s body is 3 inches wider than the humble Allroad’s, with fenders that push out for a more muscular stance (and improved handling). And it rides an inch lower to the ground. The RS6 has the same front doors, roof, and tailgate as the Allroad, but Audi says all the other exterior parts got subbed out. 

Up front, the RS6 Avant has a big black grille, crisp LED headlights, and generous openings in its bumper. But it doesn’t have the wild geometric shapes of a BMW M5 Touring or the traditionally luxurious chrome of a Mercedes-Benz E53 AMG. Around the back, the RS6 Avant has those big oval exhaust tips we mentioned. And the wagon’s body leans forward gracefully, like it’s eager to go. But simple details keep it timeless and classy – or, to some tastes, too dull. To trade some practicality for more visual personality, Audi also sells the RS7 five-door liftback with an even lower, sportier body.

Carbon Twill, Alcantara, and Lots of Screens

The Audi RS6 Avant hasn’t changed much since it hit the U.S. market in the 2021 model year. And its interior goes back two more years before that, shared with the standard Audi A6 sold from 2019 to 2025. 

If you’re no fan of Audi’s latest generation of screen-heavy interiors, this might sound like a win. The standard A6, redesigned this year, has a 14.5-inch touchscreen dominating its upper dashboard. But even this RS6 Avant has lots of screens – a 10.1-inch touchscreen infotainment system, a separate 8.6-inch touchscreen for climate controls, and a 12.3-inch customizable digital gauge cluster. The upper screen can be cluttered at times, but you can spread things out by shifting some information (including a full GPS map) to the gauge cluster. We also didn’t care for the touch-sensitive headlight controls. 

The RS6 Avant’s interior is richly finished with a sporty flavor. The seats are upholstered in Valcona leather, and textured “carbon twill” dresses up the dashboard and door panels. Our test vehicle added Alcantara suede trim on the steering wheel, shifter, and sides of the center console, plus spiffy blue seatbelts.

Family-Friendly Seating

We’ve talked about the RS6 Avant as a fashion statement – an intentional desire to not scream “look how fast and expensive my car is.” But there are also functional advantages, starting with a roomy and comfortable interior. 

The front seats are comfortable and supportive, and they come standard with both heating and ventilation. Massaging seats are available as an option, too, but my test car didn’t have them. The backseat is comfortable for two people, and three can fit as well. Built-in windowshades are a nice family-friendly feature, too. The RS6 Avant is a sports car that has room to double as a family car or do carpool duty – or to bring everyone along for the fun.

Long, Low Cargo Hold

The RS6 Avant has a lot of cargo space for a performance car. But while some folks like to think of station wagons as more practical than image-focused SUVs, this Audi isn’t a cargo-carrying master. 

By the numbers, the RS6 Avant has 30 cubic feet behind the rear seat. That’s good even by SUV standards, and it includes a lot of useful floor space to spread out your luggage or groceries. But the roof is low, and the rear windshield isn’t very upright. So bulky items won’t fit as well. We couldn’t fit a child’s bicycle because the angled windshield got in the way of the wheel. (The cargo hold’s sturdy carpeting was unfazed by our attempts to wrestle in the bike, at least!) The rear seat folds down in a handy 40-20-40 split to open up more cargo space. But the RS6 Avant isn’t rated to tow a trailer like an SUV.

Exclusive Pricing

As we mentioned, the 2026 Audi RS6 Avant starts at $130,800. That’s before a mandatory $1,295 destination charge and the $1,300 gas-guzzler tax. This isn’t any old fast family car – it’s an exotic for the lucky few who have the budget for it. 

If you’re looking to make a financial case for it, the RS6 Avant can be both a family car and a weekend car. For instance, it could replace both a $75,000 Chevrolet Corvette Stingray and a $60,000 Audi Q5 four-cylinder crossover – though you’d still have to budget some extra gas money versus either of those. 

Our test car had nearly $30,000 worth of extra-cost features. These run from basics like adaptive cruise control to premium add-ons like the $3,050 Executive Package (automatically closing doors, heated rear seats, a head-up display, remote parking assistance, and extra leather upholstery), $9,000 for ceramic brakes, and $11,000 worth of appearance items, from extra-cost paint to larger wheels to the blue seatbelts.

RS6 Avant vs. the Competition

It’s amazing that a car like the RS6 Avant should have any direct competitors at all, and yet, it has two: the BMW M5 Touring and the Mercedes-Benz E53 AMG wagon. Both of these are high-performance, high-end mid-size station wagons, creating an unlikely wealth of choice in this niche. 

Of the three, the 2026 RS6 Avant is the only one with a gas-only powertrain. The other two pair their turbocharged gas engines (a V8 in the BMW, an inline six-cylinder in the Benz) with electric motors. They’re plug-in hybrids whose batteries can get charged up using electricity from the grid. They can use that energy to boost their acceleration or run using only electricity for short drives (41 miles in the E53 and 25 miles in the M5, in EPA testing). 

The RS6 Avant is several hundred pounds lighter than those wagons, which makes it quicker and more agile than either of them. All three are quick and agile, though – we’re talking about three cars that each hit 60 mph in less than 4 seconds. But it’s also the most expensive of the trio, even before you factor in its gas-guzzler charge. 

If you want a six-figure high-performance station wagon, it makes sense to try out all three. Just prepare for the Audi to be the most old-school of the bunch – for now. Expect the next-generation RS6 Avant to come out soon and also become a plug-in hybrid with a bigger touchscreen.

Wild Yet Functional, and Not an SUV

The 2026 Audi RS6 Avant is a masterful blend of luxury, speed, and functionality. It’s terrific fun to drive, and with the raw edge that’s missing from most modern high-end performance cars. And since it’s a roomy station wagon, it’s a viable high-end family car, too.

Plus, to the right person, it’s cool to favor an “uncool” wagon over a more popular SUV. 

The RS6 Avant is frightfully expensive and uses a frightful amount of gasoline. The infotainment system isn’t cutting-edge, and the cargo hold isn’t perfectly shaped for bulky cargo. But if you’re interested, it’s time to grab one of the last 2026 RS6 Avants. It’ll be a while before anyone sells another car quite like it.
