Audi's Biggest Car Ever Debuts July 29, and the Cabin Came First

Audi has fixed a date for its biggest car ever, and dropped just enough of the interior to make the wait interesting.

Audi usually keeps a tight grip on its flagship reveals, so it's a little surprising the company has already put a date on the Q9. The covers come off on July 29, 2026, and until then the brand is feeding out details on its own terms.

What we can say for certain is still limited, and Audi wants it that way. The Q9 is the first full-size SUV the four rings have ever built, and it takes over as the new flagship. Anything below the level of confirmed interior detail is, for now, reported or expected. The complete official spec sheet, the one with power figures and dimensions on it, lands on debut day.

What Audi has actually confirmed

Ahead of the reveal, Audi gave us a first look at the cabin, and that's the part we can take as confirmed. The Q9 seats up to seven, in either a six or seven-seat layout, with electrically folding seatbacks and easy access to the third row. It is the first Audi with fully electric doors on every door, operated from the key, the myAudi app, the MMI, the brake pedal, or the seatbelt buckle. Overhead sits a panoramic glass roof of roughly 1.5 square metres, split into nine individually controllable segments that switch between clear and opaque.

Audi also confirmed a Bang & Olufsen system with what it calls 4D sound, headrest speakers for private calls and navigation prompts, and seat actuators that add a physical pulse to music. Front occupants get sports seats with ventilation and massage; the second-row chairs are ventilated too. This is a cabin built around arrival and rear-seat comfort rather than aggression, which tells you plenty about where the car is aimed.

Where it sits in the range

The Q9 is expected to slot in above the Q8 as the largest and most senior model Audi sells, taking on the flagship role the A8 saloon has held for decades as luxury buyers have migrated to tall three-row SUVs. That puts it squarely against the BMW X7, the Mercedes-Benz GLS and the Range Rover. Audi's CEO Gernot Döllner has framed the car as one of the brand's "mobile living spaces," which fits the passenger-first pitch of the cabin reveal. Anything more precise about positioning stays reported until the launch.

Powertrains: what to expect on July 29

This is the part to be careful with. Audi has not published any powertrain specifics for the Q9, so whatever you read about outputs today is expectation, not fact. Reports point to combustion engines with mild-hybrid assistance and at least one plug-in hybrid on a group platform, with a fully electric equivalent handled separately under the e-tron banner rather than as a Q9 variant. Treat all of that as reported until Audi confirms it.

No horsepower, torque, battery or dimension figures have been officially released. We are deliberately not quoting numbers that Audi has not stated. Expect the full specification, market timing and pricing to be confirmed at or around the July 29 premiere.

Inside the flagship

The materials list reads like Audi emptying the good cupboard: alpaca wool, Dinamica microfibre, Nappa leather and natural ash trim, plus new tamarind brown and stone beige colourways, most of it leaning matte rather than glossy. The practical stuff carries over as well, with Qi2.2 wireless charging pads, USB-C ports up to 100 watts and a rail-and-hook system in the cargo bay. On the top trim, the panoramic roof adds 84 LEDs across 30 colours synced to the ambient lighting. It is a lot, and it is all officially on the record.

When you can actually see one

The world premiere is set for July 29, 2026. Market rollout, trim structure and pricing have not been announced, and Audi has not detailed a US on-sale window yet. Given the segment, expect a fair walk from the reveal to showrooms, with fuller regional information following the debut. We will update once Audi puts the real numbers on the table.
