Audi Q9

What is the Audi Q9?

The Audi Q9 is a full-size, three-row luxury SUV that sits at the very top of Audi’s range, above the Q7 and Q8. Audi positions it as the successor in spirit to the discontinued A8 limousine — a “mobile living space” rather than a sports SUV — and its direct rivals are the BMW X7, Mercedes-Benz GLS and Range Rover.

Revealed on 29 July 2026, the Q9 is the first genuinely full-size SUV Audi has ever made. It was developed primarily for North America, China and the Middle East, which explains its scale: at 5.31 m long and 2.21 m wide it is larger than every German rival and one of the largest passenger cars sold in the UK. It is built on the Volkswagen Group’s Premium Platform Combustion (PPC) alongside the Audi Q7 in Bratislava, and will also form the technical basis of Porsche’s planned flagship SUV, known internally as “K1”.

Where does it sit in Audi’s line-up?

The Q9 is now Audi’s flagship. With the A8 saloon discontinued, the Q9 inherits its role as the brand’s statement of maximum luxury — the car Audi expects to compete for executive, chauffeur and family-flagship buyers who would previously have cross-shopped an A8, S-Class or Range Rover. The Q7 continues beneath it as the “sensible” large seven-seater; the Q8 remains the sportier five-seat coupé-SUV.

Audi Q9 vs Audi Q7 — the key differences

• Size: the Q9 is roughly 240 mm longer than the current Q7 and rides on a wheelbase around 140 mm longer, transforming third-row and boot usability.
• Positioning: the Q7 starts from a little over £82,000; the Q9 is expected to open above £100,000 Estimated.
• Cabin ambition: the Q9 introduces automatic power doors, optional individual electric second-row seats, Audi’s largest-ever panoramic roof and a 4D Bang & Olufsen system — none of which define the Q7.
• Audience: the Q7 is a premium family car; the Q9 is a flagship aimed at buyers comparing Range Rover and GLS levels of presence.

Who should buy it?

The Q9 is aimed at high-net-worth family buyers who need genuine six- or seven-adult capability, executives and business owners who want first-class rear seating without a limousine, chauffeur and executive-hire operators, and corporate fleets running director-level vehicles. It is best suited to owners with off-street parking — a point covered honestly in the London Ownership Guide below.

Why the Q9 matters

Audi Q9 specifications (UK)

Confirmed Audi Q9 dimensions: 5,310 mm long, 2,210 mm wide, 1,810 mm tall, on a 3,140 mm wheelbase. The UK launch engine is a 3.0-litre V6 TDI mild-hybrid diesel producing 299 PS and around 640 Nm, with an eight-speed automatic and quattro all-wheel drive. Full UK specifications, weights and economy figures are yet to be published.

Every value below is labelled by provenance. “Official” figures come from Audi’s launch material; “Estimated” values are London Auto Index conversions or projections; “TBC” means Audi has not yet published a UK figure. We will update this table when UK homologation data is released.

Audi Q9 engines: what launches in the UK, and what may follow

At UK launch the Audi Q9 is offered with one engine: a 3.0-litre V6 TDI mild-hybrid diesel with 299 PS. A 2.9-litre twin-turbo V6 petrol exists for other markets, the 591 hp SQ9 V8 has been confirmed as not coming to the UK, and no plug-in hybrid or electric Q9 has been announced.

Why is Audi launching the Q9 with a diesel engine? Because the Q9’s core mission — heavy, long-distance, multi-occupant luxury travel — is the one segment where diesel still objectively outperforms petrol and, for many buyers without home charging, electric. Audi’s stated position is that significant demand remains for combustion range and convenience in a vehicle of this size, while a dedicated electric flagship follows separately. For London-specific diesel implications (ULEZ, Congestion Charge), see the London Ownership Guide.

Interior: Audi’s “mobile living space”

The Audi Q9’s cabin offers six or seven seats across three rows, a dashboard with driver, central (14.5-inch, Android Automotive) and passenger displays, automatic doors, Audi’s largest-ever panoramic glass roof, and a 4D Bang & Olufsen sound system. Audi describes it as a mobile living space rather than a driver’s cockpit.

Exterior design: presence by the metre

The Q9’s design is defined by scale: a vast Singleframe grille (illuminated on higher trims), clean vertical surfaces, a long roofline with upright tail, wheels from 20 to 23 inches, and the first curved digital OLED rear lights fitted to any production car.

Audi’s designers talk openly about presence — the intent that the Q9 is recognised, and slightly imposing, the moment it arrives. The standard grille uses giant vertical vanes; S line trim swaps it for a bolder open design without slats, a more pronounced lower front end and an accentuated rear spoiler. Matrix LED headlights with digital lighting signatures feature, while the rear carries a full-width light bar with illuminated Audi rings and third-generation digital OLED clusters: six curved three-dimensional panels using 512 individually controlled segments that follow the bodywork’s contour and improve side visibility at night.

The boxy rear three-quarters is honest packaging: the long rear overhang buys third-row headroom and boot volume. Aerodynamic detailing is restrained — this is a car shaped by interior space first. Launch colour and wheel options for the UK have not yet been published Not yet announced; we will list the UK palette when Audi UK releases configurator data.

Technology and driver assistance

The Audi Q9 pairs Android Automotive-based infotainment, an upgraded AI voice assistant and over-the-air updates with a full suite of advanced driver-assistance systems. Exact UK ADAS specification by trim is yet to be confirmed.

• Driver assistance (ADAS): adaptive cruise control with lane guidance, park assist with remote operation via the Audi app, and surround cameras are expected across the range, consistent with Audi’s current flagship hardware Expected. Features such as night vision and head-up display have appeared on Audi’s flagships previously; UK standard/optional status on the Q9 is Not yet announced.
• Automatic doors: power-operated, app-controllable, with obstacle sensing to prevent opening into passing traffic or cyclists — notable for kerbside use in dense urban streets.
• Infotainment: 14.5-inch central touchscreen on Android Automotive OS, passenger display, upgraded natural-language voice assistant, and OTA software updates.
• Connectivity: wireless Apple CarPlay and Android Auto are expected as standard Expected; connected services run through the myAudi app, which also controls the doors, climate preconditioning and vehicle status remotely.

Safety: expectations ahead of testing

The Audi Q9 has not yet been tested by Euro NCAP. Based on Audi’s recent record — five-star results for the related Q6 e-tron and A5/Q5 generation cars — a five-star rating is the reasonable expectation, but it remains unconfirmed.

• Crash protection: the PPC platform underpinning the Q9 supports the latest passive-safety structures and airbag arrays; specific Q9 results will be added when Euro NCAP publishes them Not yet announced.
• Child safety: Isofix/LATCH mounting in both the second and third rows, and electric second-row seats that can tilt and slide with a forward-facing child seat still installed — unusually family-literate engineering for the class.
• Active safety: autonomous emergency braking, lane assistance and the full Audi pre sense suite are expected as standard across UK trims Expected.
• Security: UK-market security specification (Thatcham status, keyless-theft protections such as motion-sense keys) is not yet published Not yet announced — worth checking at order, as insurers will price it.

What will the Q9 be like to drive?

No UK road tests exist yet — the Q9 was revealed on 29 July 2026 and first drives will follow closer to customer deliveries. What is knowable now: standard adaptive air suspension, a torque-rich V6 diesel, quattro traction and a cabin engineered for isolation point clearly at long-distance comfort rather than agility. This section states expectations, and we will replace it with verified impressions after first drives.

• Motorway: this is the Q9’s natural habitat. 640 Nm at cruising revs, air suspension and a diesel’s 600-mile-plus theoretical range should make it a formidable M4/M25/M40 companion for London–country commuters.
• London traffic: the mild-hybrid system smooths stop-start running, the automatic doors and surround cameras help kerbside, and the elevated view is commanding. The constraint is geometry, not refinement — see the width and length analysis below.
• Country roads: expect disciplined rather than playful. A 2.4-tonne, 5.31 m SUV on air springs prioritises composure; B-road width will be the more noticeable limitation on Surrey and Buckinghamshire lanes.
• Ride, steering and noise: Audi’s brief for the Q9 is “mobile living space” — the engineering priorities are ride isolation, low cabin noise and effortless steering rather than feedback. Judged against that brief, and against the X7 and GLS, refinement is where the Q9 must win.

Audi Q9 running costs in the UK

Official Q9 running-cost data does not exist yet. What can be stated with confidence: at an expected list price above £100,000 the Q9 will attract the Expensive Car Supplement on road tax, a top-band first-year VED charge, insurance at or near the highest group, and premium-SUV servicing and tyre costs. Figures below are indicative and dated; verify at order.

Finance: UK lease, PCP and business contract hire pricing cannot exist before Audi publishes list prices — any “Audi Q9 lease deal” advertised before official UK pricing should be treated as provisional. Once pricing lands, expect the Q9 to be quoted heavily through business contract hire for company use (100% of finance rental VAT reclaimable is not available on cars with private use — typically 50% on the finance element — and diesel’s BIK position makes outright company-car use expensive; many buyers will run it through salary or personally instead). For monthly-cost comparisons against the BMW X7 and Range Rover once live pricing exists, see our luxury SUV cost guide.

The Audi Q9 in London: the honest assessment

Is the Audi Q9 too big for London? For on-street central-London life, effectively yes: at 2.21 m wide it will not pass through London’s common 7 ft (2.13 m) width restrictors, and at 5.31 m it is roughly 50 cm longer than a standard 4.8 m UK parking bay. It is, however, expected to be ULEZ-compliant as a new Euro 6 diesel, so the daily ULEZ charge does not apply. The Q9 works in London for owners with driveways, gated parking or chauffeur arrangements — and works best from outer London and the home counties.

The size verdict, measured

ULEZ, Congestion Charge and borough parking

• ULEZ: the Q9’s launch diesel is a new Euro 6 engine, and Euro 6 diesels meet the ULEZ standard — so we expect the Q9 to be ULEZ-compliant with no £12.50 daily charge Expected — verify the registered vehicle at tfl.gov.uk once on sale. This is the first question every London buyer asks of a new diesel, and the answer here is favourable.
• Congestion Charge: payable in full. No exemption applies to any combustion Q9 — budget £18 per day (rate as of 2026; check TfL for current pricing) for regular Central London entry.
• Borough parking: several London boroughs now surcharge resident permits by emissions, engine size or, in some cases, vehicle length/weight — a large diesel typically lands in the most expensive permit tier. Check your borough’s schedule (we track this on our borough guides) before assuming a permit is economic. In practice, a Q9 parked on-street in Kensington, Chelsea or Islington is both expensive and physically awkward; this is a driveway car.

Central London, borough by borough

Central-London prime postcodes are where the Q9’s scale is most felt. In Kensington and Chelsea, and around Mayfair and Westminster, mews streets, historic width restrictors and premium-priced, size-tiered resident permits combine to make on-street Q9 ownership genuinely impractical — this is a car for a private garage or off-street bay in these boroughs, not the kerb. Richmond is more forgiving: wider suburban roads and driveway-led housing stock suit the Q9 far better, while still giving quick access into town via the A316/A4.

Surrey and Heathrow commuter routes

This is the Q9’s natural London-adjacent habitat. Surrey commuter routes into the City or Canary Wharf via the A3, M25 and A316 play directly to the diesel V6’s torque and range, and driveway parking is the norm rather than the exception in most Surrey commuter towns. The same applies to Heathrow journeys: a large, comfortable, motorway-composed SUV with strong towing and luggage capacity is a natural fit for regular airport runs, and Heathrow’s own car parks and drop-off zones are sized for large vehicles, unlike a Kensington mews.

Family and executive/business use

For family ownership, the Q9’s electric-access third row, tilt-and-slide second row (usable even with a forward-facing child seat fitted) and near-2,500-litre maximum load space make it one of the most practical three-row options in the class — provided the household has off-street parking for daily use. For executive and business use, the six-seat configuration with individual heated and ventilated rear chairs is a direct, purpose-built answer to chauffeur and boardroom-collection duties, an area where the Q9 inherits the A8’s old remit more convincingly than the standard Q7 ever did.

Where the Q9 makes sense

• Best-case London ownership: a driveway or gated/underground parking in outer boroughs — Richmond, Wimbledon, Hampstead Garden Suburb, Dulwich — with regular motorway use. The commute in from Surrey, Buckinghamshire, Hertfordshire or Essex to Canary Wharf or the West End plays directly to the TDI’s strengths.
• Chauffeur and executive hire: the six-seat configuration with individual electric rear chairs positions the Q9 squarely against the Range Rover and Mercedes GLS in London’s chauffeur market — with the A8 gone, this is Audi’s chauffeur car. Kerbside, the sensor-guarded automatic doors are a genuine operational advantage; the width is the trade-off on Mayfair and Knightsbridge side streets.
• School runs: seven usable seats, electric access to row three and child-seat-friendly second-row mechanisms are excellent; the constraint is the school-gate parking scrum, where 5.31 m demands patience.
• Poor fit: daily on-street parking in central boroughs, mews houses, standard multi-storey car parks (height is fine at 1.81 m; bay length and turning geometry are not), and routes gated by width restrictors — common across residential rat-run prevention schemes in west and south-west London.

Can you daily-drive an Audi Q9 in central London? Physically yes — it is no taller than a Range Rover and the cameras and automatic doors help — but only sensibly if you have off-street parking at both ends of your typical journey and your routes avoid width-restricted streets. Otherwise the Q7, at ~5.07 m and usefully narrower, is the same brand’s better London answer.

Audi Q9 vs BMW X7, Mercedes GLS, Range Rover and Porsche Cayenne

The Audi Q9 out-measures every direct rival: it is longer and wider than the BMW X7 and Mercedes-Benz GLS and comparable in scale to a long-wheelbase Range Rover. Its case rests on cabin technology, rear-seat luxury and being the newest design in the class; its open questions are UK pricing, residual values and the absence — for now — of any hybrid option.

Rival figures are approximate manufacturer/market data for current-generation models as of July 2026, provided for orientation; verify current pricing with manufacturers.

Audi Q9 buying guide: order timing, spec and finance

Buy the Q9 if you need genuine three-row luxury, cover serious motorway miles, and have off-street parking. Don’t buy it as a central-London on-street car, as a driver’s SUV, or if you need a plug-in hybrid. Order timing: UK order books are expected to open in late August 2026, with first deliveries by the end of 2026 — early orders will define the initial waiting list.

How to order an Audi Q9 in London

Audi is expected to open UK order books in late August 2026, with pricing and full UK specifications announced around the same time and first deliveries before the end of the year. London buyers can register interest now through Audi UK or any London Audi centre — including West London Audi (Hounslow) within the Sytner group, profiled in our London prestige dealerships directory. Expect demonstrator and test-drive cars to reach London showrooms close to the delivery window, not before; if a test drive is a condition of your order, tell your dealer at registration so you’re sequenced for the first demonstrator allocation.

Should You Buy the Audi Q9?

Buy the Q9 if you need genuine three-row luxury for six or seven people, cover serious motorway mileage, and have off-street parking. Consider a smaller or more electrified alternative if your driving is mostly urban, you want a sportier drive, or on-street parking is your only option.
