The 2027 Audi Q9 represents a major expansion for Audi in the United States. For the first time, Audi is entering the full-size luxury SUV segment with a three-row vehicle designed to compete directly with some of the most established names in the category.

That includes the Mercedes-Benz GLS 450, BMW X7 and Cadillac Escalade.

The Q9 is larger than both the BMW X7 and Mercedes-Benz GLS, offers 429 horsepower from a twin-turbo V6, has standard adaptive air suspension, available six- or seven-passenger seating, and introduces a new level of digital technology to Audi's SUV lineup.

But how does it actually compare?

Let's take a closer look at size, performance, interior space, technology, safety, driver assistance and everyday practicality.

2027 Audi Q9 vs. the Competition at a Glance

Specifications can vary by model year, trim and equipment. Q9 specifications are based on currently announced U.S. information.

Size: The Q9 Is Clearly a Full-Size SUV

Audi has made one thing very clear with the Q9: this isn't simply a larger Q7.

At 209 inches long, the Q9 is approximately 5.4 inches longer than the BMW X7 and 4 inches longer than the Mercedes-Benz GLS. It is also only about 3 inches shorter than the standard-length Cadillac Escalade.

The Q9's 123.5-inch wheelbase is also slightly longer than the GLS and X7.

Interestingly, Audi hasn't simply used the additional size to create a giant exterior footprint. The Q9 remains somewhat lower than the Escalade, giving it a more traditionally European SUV profile.

Where the Q9 stands

Longest of the German competitors: Q9

Largest overall: Cadillac Escalade

Longest wheelbase: Q9

Most third-row cargo among the German competitors: Q9

The Escalade remains the sheer-size champion, particularly when the ESV is included. But the Q9 closes the gap significantly.

Interior Space: Audi Focuses on Usable Three-Row Luxury

A full-size SUV needs to do more than look large.

It needs to accommodate people comfortably while still leaving room for luggage, groceries, sports equipment and everything else a three-row SUV is expected to carry.

Audi says the Q9 provides 19.3 cubic feet of cargo space behind the third row, which is more than the GLS and substantially more than the X7. Maximum cargo capacity reaches 87.7 cubic feet with the rear seating folded.

The Q9 can also be configured with either six or seven seats.

For buyers who want a more luxurious second row, available individual second-row seats provide a more executive-style experience.

The Cadillac Escalade still has a significant advantage in absolute cargo volume, particularly the Escalade ESV. But among the German competitors, Audi has clearly prioritized making the Q9 useful as a family vehicle.

Power: Audi Enters the Segment Strong

The standard 2027 Audi Q9 is powered by a 2.9-liter twin-turbocharged V6 producing 429 horsepower and 442 lb-ft of torque.

Audi pairs the engine with an eight-speed automatic transmission and all-wheel drive.

The result is an estimated 0–60 mph time of 4.9 seconds.

That gives the Q9 a meaningful power advantage over the standard BMW X7 xDrive40i and Mercedes-Benz GLS 450.

The current X7 xDrive40i produces 375 hp and 398 lb-ft of torque, while the GLS 450 produces 375 hp and 369 lb-ft. Both use turbocharged six-cylinder engines with mild-hybrid technology.

The Cadillac Escalade takes a different approach with its naturally aspirated 6.2-liter V8, producing 420 hp and 460 lb-ft of torque.

Performance comparison

Audi Q9: 429 hp

Cadillac Escalade: 420 hp

BMW X7 xDrive40i: 375 hp

Mercedes-Benz GLS 450: 375 hp

The Q9 therefore enters the segment with one of the strongest standard powertrains.

And for buyers who want even more performance, Audi has announced the 591-hp SQ9, powered by a twin-turbocharged 4.0-liter V8.

Towing: All Four Are Serious Tow Vehicles

For many luxury SUV buyers, towing capacity matters.

The Q9 is rated to tow up to 7,700 pounds, matching the Mercedes-Benz GLS 450.

The BMW X7 is rated at up to 7,500 pounds, while the Cadillac Escalade can tow up to 8,100 pounds in its maximum-rated configuration.

Towing winner

Cadillac Escalade — up to 8,100 lbs.

But the Q9 is right behind it and matches the GLS.

Ride and Handling: A Different Interpretation of "Full Size"

The Q9 comes standard with adaptive air suspension with adaptive damping, giving Audi the ability to adjust ride height and suspension characteristics depending on driving conditions.

The Mercedes-Benz GLS 450 also uses AIRMATIC self-leveling air suspension with adaptive damping.

BMW takes a similarly sophisticated approach with the X7's suspension technology.
The distinction is more about philosophy.

The Escalade is a traditional American full-size luxury SUV: tall, imposing and exceptionally spacious.

The Q9 is designed to deliver the size and practicality of a full-size SUV while maintaining the driving characteristics expected from an Audi.

That could make the Q9 particularly appealing to buyers who want three-row space without feeling like they're driving something larger than necessary.

Technology: Audi's Digital Approach

Technology is one of the areas where the Q9 is making a particularly strong statement.

Audi's new flagship features a digital cockpit centered around its latest MMI infotainment system, Audi virtual cockpit technology and multiple high-resolution displays.

The Q9 also offers a 12.3-inch passenger display, giving the front passenger an independent screen for entertainment and applications.

Other available technology includes:

• Head-up display
• Audi virtual cockpit plus
• High-resolution central displays
• Wireless smartphone charging
• Multiple USB connections
• Available five-zone climate control
• Available ambient lighting
• Available automatic doors
• Power-folding second- and third-row seats
• Available massaging and ventilated seats
• Available Bang & Olufsen audio
• Available panoramic glass roof

Audi has also incorporated a feature becoming increasingly important in luxury vehicles: remote vehicle control through the manufacturer's connected-services ecosystem.

Through myAudi, owners can interact with various vehicle functions remotely, depending on equipment and subscription availability.

Mercedes-Benz MBUX

The GLS counters with Mercedes-Benz's MBUX infotainment system.

The GLS also offers sophisticated voice control, connected services, navigation, smartphone integration and available rear-seat entertainment.

Mercedes-Benz offers extensive luxury upgrades including executive rear seating, heated and ventilated second-row seats and MBUX High-End Rear Seat Entertainment.

BMW iDrive

The BMW X7 uses BMW's latest-generation digital interface and offers a large central display, smartphone connectivity, navigation and connected services.

BMW's strength has traditionally been the integration of digital technology with the driver's interface and vehicle controls.

Cadillac Technology

The Escalade takes perhaps the most dramatic visual approach.

Its available 55-inch Horizon Display stretches across the front of the cabin, while available AKG audio systems provide up to 38 speakers on the gasoline Escalade.

Cadillac also offers Google built-in, connected services and an especially important differentiator in this class: Super Cruise.

Driver Assistance and Safety

Safety technology has become one of the most important considerations in a three-row luxury SUV.

The Q9 introduces an extensive collection of driver-assistance technologies, including systems designed to assist with lane positioning, collision avoidance, parking and highway driving.

One of the most notable Q9 features is its available hands-free driving capability on select highways.

Audi says the system can monitor its surroundings and control steering and throttle inputs on specified routes, with a three-year trial offered on select configurations.

Audi also offers advanced lighting technology, including available Digital Matrix LED headlights and OLED lighting technology.

Mercedes-Benz Driver Assistance

The GLS offers Mercedes-Benz's extensive suite of driver-assistance technologies, including available advanced adaptive cruise and lane-support systems.

The Mercedes approach focuses heavily on integrating driver assistance into the MBUX ecosystem.

BMW Driver Assistance

BMW similarly offers an extensive range of active safety and driver-assistance technology, including collision warning, lane assistance, parking assistance and adaptive cruise capabilities depending on configuration.

Cadillac Super Cruise

Cadillac arguably has the strongest brand recognition in this particular category because of Super Cruise.

The 2026 Escalade includes Super Cruise as standard, along with a three-year OnStar One plan. The system uses cameras, radar and precision LiDAR mapping to provide hands-free driving assistance on compatible roads.

For shoppers who spend significant time commuting or traveling on highways, this can be a major consideration.

Lighting Technology: Audi's Secret Weapon

One area where Audi has historically differentiated itself is lighting technology.
The Q9 continues that tradition.

Available Digital Matrix LED headlights can intelligently shape the light distribution around other vehicles, while Audi's available OLED rear lighting can create different light signatures and warning displays.

Audi has even incorporated lighting communication into the Q9's design, allowing the vehicle's lighting system to provide information to surrounding road users in certain situations.

It's a good example of Audi's philosophy: technology isn't simply about adding larger screens—it can also improve visibility and communication.

Luxury and Comfort

All four SUVs can be equipped to deliver an extremely high level of luxury.
But they approach luxury differently.

• Clean, modern design
• Premium materials
• Digital technology
• Available six-seat configuration

Size Isn't Everything: The Biggest Difference Between These SUVs

Looking strictly at dimensions, the Cadillac Escalade is still the largest vehicle here.
But the Q9 changes the traditional German luxury SUV equation.

The BMW X7 and Mercedes-Benz GLS have historically occupied the space between traditional luxury SUVs and full-size American SUVs.

The Q9 moves Audi closer to the Escalade category while retaining the dimensions and proportions of a European luxury SUV.

At 209 inches long, it is:

5.4 inches longer than the X7

4 inches longer than the GLS

Only 2.9 inches shorter than the Escalade

That is a significant statement from Audi.

The 2027 Audi Q9 Changes the Conversation

The most important thing about the 2027 Audi Q9 may not be any single specification.
It's that Audi has finally entered a segment where Mercedes-Benz, BMW and Cadillac have traditionally dominated.

The Q9 isn't simply a larger Q7. It is Audi's new flagship SUV and has been engineered to compete at the top of the three-row luxury market.

With 429 horsepower, a 4.9-second 0–60 mph time, a 123.5-inch wheelbase, available six- or seven-passenger seating, up to 87.7 cubic feet of cargo capacity and a new generation of digital and driver-assistance technology, the Q9 gives buyers another serious option in the full-size luxury SUV market.
