Audi has been selling premium vehicles in America for decades without a genuine full-size SUV to its name. That changes in Q4 2026 when the 2027 Q9 reaches dealers, priced from $87,700 before destination. It is the first Audi to wear the number 9, positioned above the Q8, and it arrives carrying the additional weight of replacing the A8 sedan as the brand’s flagship as that car’s production winds down in 2027.
The competition it enters is well-established. Mercedes-Benz has been selling the GL and GLS lineage for 20 years, and the BMW X7 is already eight years old. Audi is not early to the three-row full-size luxury SUV segment by any reasonable measure. The Q9 needs to justify the wait with hardware the incumbents don’t offer.
On dimensions alone, the Q9 makes a statement. It stretches 209.0 inches long, stands 71.4 inches tall, and spans 86.8 inches wide on a 123.5-inch wheelbase. That wheelbase is longer than a Chevrolet Tahoe’s, and Audi has used the room purposefully. Seven-seat configuration is standard, with a 35/30/35 split in the second row and genuine adult space in the third. The optional six-seat layout swaps the second-row bench for two power-adjustable captain’s chairs with available seat heating, prioritizing a business-class atmosphere over raw headcount.
Access to that third row gets specific engineering attention. The outer second-row seat slides forward electrically and tilts without folding, meaning a forward-facing child seat installed there doesn’t have to come out every time someone needs to climb past it. All seats across all three rows are power-adjustable regardless of configuration, a genuine differentiator in a segment where third-row power adjustment remains uncommon.
The automatic doors are new for Audi and worth explaining beyond the headline. Each door opens up to 90 degrees, with obstacle detection that can stop or prevent the door from swinging into traffic, pedestrians, or cyclists. An electric soft-close mechanism pulls the door shut gently if it isn’t fully latched. The doors can be opened and closed remotely via the myAudi app. It is the kind of feature that sounds like a luxury indulgence until a school pickup line makes it feel essential.
The panoramic sunroof covers more than 16 square feet of glass and is the largest ever fitted to an Audi. Optional switchable transparency uses polymer-dispersed liquid crystal laminated glass divided into nine individually controllable segments, letting occupants toggle between full transparency and full opacity. When parked, the roof automatically turns opaque to reduce cabin heat and preserve privacy, reverting to the last setting when the car is restarted. A conventional sunshade is not needed; the standard coated laminated glass blocks more than 99.5 percent of UV radiation.
At launch, one powertrain is available: a twin-turbocharged 2.9-liter V6 producing 429 hp and 442 lb-ft of torque, mated to an eight-speed Tiptronic transmission with standard quattro all-wheel drive. Audi claims 0-60 mph in 4.9 seconds, citing best-in-class standing among the 2027 BMW X7 xDrive40i, 2027 Mercedes-Benz GLS 450 4MATIC, 2026 Range Rover SE LWB, and 2026 Lexus LX600. Adaptive air suspension is standard across the lineup, combining continuously variable damping with adjustable ride height spanning a total range of 3.5 inches between the lowest and highest modes. All-wheel steering, which can steer the rear wheels up to 5 degrees in either direction, comes standard on Q9 Prestige trim.
The lighting package on the Q9 Prestige is legitimately novel. The third-generation curved digital OLED taillights use a 0.1-millimeter glass substrate to follow the body contours in three dimensions, a world-first on a production vehicle. Six large OLED panels contain 512 total segments: 99 in the outer curved panel, 84 in the center, and 73 in the inner panel. A continuous LED light strip connecting the two taillights spans the full rear width, making the vehicle appear substantially wider after dark. Eight customizable digital light signatures come with the Prestige taillights. The advanced turn signals add a ground projection of a stylized indicator at night, synchronized with the dynamic front and rear turn signals, improving lateral visibility when changing lanes.
Up front, the Q9 introduces Digital Matrix LED headlights with adaptive beam functionality to the U.S. market for the first time. Unlike a conventional high beam that simply switches on or off, the system uses a front-facing camera to continuously shape a precise shadow around oncoming and preceding vehicles, maintaining high-resolution illumination on the road without sending glare into other drivers’ mirrors. Audi describes this technology as already common in Europe; U.S. regulation previously prevented it.
Hands-free highway driving, marketed as adaptive cruise assist plus, operates at speeds up to 85 mph on approved road segments in both the U.S. and Germany at launch. It handles steering, acceleration, and braking with the driver’s hands off the wheel. Activating the turn signal prompts a lane-change assist. A driver monitoring camera on the steering column tracks eye position and head movement; if attention lapses, the system escalates through visual, audible, and haptic warnings before emergency assist brings the vehicle to a controlled stop. This feature is standard on SQ9 and Q9 Premium Plus and Prestige grades.
The infotainment center is built around an MMI panoramic display combining an 11.9-inch Audi virtual cockpit and a 14.5-inch MMI touch display, both using OLED technology in a curved format. A 12.3-inch passenger display with dynamic privacy mode comes standard. The system runs Android Automotive OS with an integrated Audi Application Store. Voice control integrates an AI-powered Audi assistant with ChatGPT connectivity for general knowledge queries, available with an Audi connect NAV subscription. An optional factory-integrated dashcam records to a microSD card.
Audio options run from a standard system to an optional Bang & Olufsen Premium Sound System with 4D sound, 22 speakers, two seat actuators, and 1,360 watts of total output. The seat actuators generate vibrations synchronized to music, and the system uses Fraunhofer Symphoria for adaptive sound distribution. It is the kind of spec that reads as excess until you’ve experienced how much a vibrating seat can change a concert recording at highway speed.
Storage runs to 19.3 cubic feet behind the third row, 50.0 cubic feet behind the second row, and 87.7 cubic feet with the second row folded. A standard aluminum rail system in the trunk secures cargo with sliding hooks and adjustable anchors in three dimensions. The center console includes dual wireless charging with Qi2.2 compliance; USB-C Power Delivery charging is optionally available across all three rows at up to 100 watts, enough for laptops.
Mercedes has owned this segment for two decades and BMW has had eight years to entrench the X7. The Q9 has the dimensions, the technology, and the price point to compete. Whether Audi can convert Q7 and Q8 loyalists into buyers of something significantly larger and more expensive is the real test, and that answer comes from the dealer floor, not the spec sheet.
