Audi Bets Big on the 2027 Q9 as Its US Flagship SUV

Audi’s 2027 Q9 full-size SUV starts at $87,700 and stretches 209 inches long, finally giving the brand a true American-scale three-row flagship built on the Premium Platform Combustion architecture.

The SQ9 performance version opens at $118,000. Both reach U.S. dealers in the fourth quarter of 2026, complete with active-matrix headlights that had been locked out of the market until now.

What the Q9 and SQ9 Bring Under the Hood

Every regular Q9 uses a turbocharged 2.9-liter V6 making 429 horsepower paired with an eight-speed automatic and standard all-wheel drive. Car and Driver lists claimed 0-60 mph in 4.9 seconds. An air-spring suspension with adaptive damping is standard; Prestige trims add rear-wheel steering that turns the rears up to five degrees.

The SQ9 steps up to the twin-turbo 4.0-liter V8 shared with certain RS6 and RS7 models. Output lands at 591 horsepower. Its all-wheel drive stays rear-biased in normal driving, and the body gains wider arches, larger alloys and a distinct illuminated grille. Both versions tow up to 7,700 pounds.

• 429 hp from the base 2.9-liter V6
• 591 hp twin-turbo V8 in the SQ9
• 7,700 lb maximum towing for Q9 and SQ9 alike
• 4.9 s claimed 0-60 mph for the V6 model

Europe will see diesel options. America sticks to gasoline. The PPC architecture also underpins the new Q7, A5 and Q5 families.

Sized for the Third Row Americans Use

At 209 inches long, 79.2 inches wide and 71.4 inches tall on a 123.5-inch wheelbase, the Q9 sits a clear step above the Q7. That wheelbase stretch of 5.6 inches mostly feeds the third row. Parked beside a Cadillac Escalade the Audi still looks a few inches smaller in most directions, yet it avoids the sheer bulk of a Mercedes-Benz GLS or BMW X7.

Body surfaces use softer curves and subtler creases than recent Audis. Big wheels create a station-wagon silhouette that reads smaller than the tape measure. Six- or seven-seat layouts are available: captains’ chairs or a three-seat bench in the middle row. Power-operated doors open nearly 90 degrees for easier third-row access.

Cabin Room, Screens and the Numbers That Matter

Cargo volume starts at 19.3 cubic feet behind the third row, rises to 50 cubic feet with that row folded, and reaches 87.7 cubic feet with everything flat. A panoramic roof with electrochromic dimming spans the ceiling in nine controllable segments and blocks more than 99.5 percent of UV light.

Front and Middle Row Features

Two wireless phone pads sit up front along with a dense array of USB-C ports, some rated to 100 watts. The digital stage includes an 11.9-inch driver cluster, 14.5-inch center touchscreen and 12.3-inch passenger display. Standard audio is a 16-speaker Bang & Olufsen system; a 22-speaker 4D version with headrest speakers and seat actuators is optional.

Materials and Lighting

Open-pore wood, alpaca-wool textiles and options such as olive leather appear alongside the darker carbon-heavy SQ9 cabin. Ambient lighting can sync to music. Dynamic interaction light runs the full cabin width. A new trunk rail system with sliding hooks adds practicality.

• Electrically operated doors with obstacle detection, first for Audi
• Panoramic roof with switchable opacity in nine zones
• Optional OLED rear lights and ground-projected turn signals
• Ventilated, massaging front seats and power-folding third-row backs

Early previews noted the third row works for adults once the second row slides forward, though legroom stays tighter than the middle seats.

How the Dimensions and Price Line Up Against Rivals

Audi priced the Q9 Premium at roughly $89,095 in some listings that include destination, with Premium Plus near $94,695 and Prestige at $103,795. The SQ9 sits at about $119,395 as a single trim. Those figures place it squarely against the BMW X7, Mercedes GLS and Cadillac Escalade.

Exact rival figures vary by year and wheelbase choice; the Q9’s 7,700-pound tow rating edges the X7’s 7,500 while trailing the Escalade’s roughly 8,100. Rear-wheel steering on higher Q9 trims aims to shrink the turning circle that full-size SUVs normally suffer.

Flagship Status Arrives Without a New A8

With no firm timeline for an A8 replacement, the Q9 becomes Audi’s range-topping model. The company describes it as the all-new flagship SUV introduction built first for comfort and space. Global materials call it the first full-size SUV to bear the four rings.

That choice reflects market reality. Full-size three-row luxury SUVs still move volume in the United States even as sedans shrink. Audi’s earlier Q7 stayed closer to European midsize packaging; the Q9 stretches into Escalade territory while keeping more car-like proportions.

The Late ICE Bet and What Buyers Notice First

Most competitors already sell mature full-size models. Audi arrives with the new PPC combustion platform, Digital Matrix LED headlights that can project lane markers and selectively blank glare, and ground-projected turn signals. Those active-matrix LED headlights coming to America finally clear U.S. regulations on the Q9 and Q7.

On X, early reactions mixed praise for the tech and space with shrugs on styling. One detailed take called the design “competent (better than some competitors) but nothing special” and wanted fewer screens plus more physical buttons while still labeling it a solid family SUV. Reveal posts from Car and Driver and Motor1 confirming the 429-hp turbocharged 2.9-liter V-6 details and 591-hp V8 drew tens of thousands of views within hours.

I’m neutral on the design of the new Audi Q9 – it’s competent (The design is better than some competitors) but nothing special. The interior materials are good, though I’d prefer more luxury and character, fewer screens and more proper buttons. Overall, a solid family SUV.

That voice, posted the morning after the reveal, captures the early split: capability accepted, emotional punch still debated.

Dealers, Rivals and the Next Twelve Months

North American sales start first, reversing Audi’s usual Europe-first pattern. Dealers gain a true Escalade fighter and a higher transaction-price flagship. The Q7 continues below it, so the brand now fields two three-row SUVs with clearer size separation.

BMW, Mercedes and Cadillac lose the “Audi has nothing here” talking point. Whether the Q9’s tech edge and slightly smaller footprint convert shoppers who already like X7 or GLS ride quality remains the open question. Warranty coverage matches the rest of the lineup: four years or 50,000 miles plus three years of complimentary maintenance.

Production and final U.S. fuel-economy figures will fill in before the first deliveries. For now the bet is on the table: a late, ICE-powered, matrix-lit, genuinely large Audi as the new face of the brand in the market that still buys the biggest luxury SUVs.
