Compare the2025 Audi Q7VS 2025 Lexus GX

The Q7’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The GX doesn’t offer pre-crash pretensioners.

Both the Q7 and GX have child safety locks to prevent children from opening the rear doors. The Q7 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The GX’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Audi Q7 achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Lexus GX has not been tested.

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The Q7 has Car-to-X Services, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The GX doesn’t offer a system that can receive automated systems from infrastructure.

To deliver safety and visibility under dusty conditions the Audi Q7’s backup monitor has a standard rear washer to keep the view clear. A camera washer system costs extra on the Lexus GX.

For better protection of the passenger compartment, the Q7 uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The GX uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the Q7 and the GX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

The Audi Q7 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and an “Acceptable” score in the revised pedestrian crash prevention test. The GX has not yet been evaluated by the IIHS for 2025.

The Q7’s corrosion warranty is 6 years longer than the GX’s (12 vs. 6 years).

There are over 25 percent more Audi dealers than there are Lexus dealers, which makes it easier should you ever need service under the Q7’s warranty.

On the EPA test cycle the Q7 gets better mileage than the GX:

Regenerative brakes improve the Q7’s fuel efficiency by converting inertia back into energy instead of wasting it. The GX doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the Q7’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The GX doesn’t offer an automatic engine start/stop system.

The Q7 has 1.4 gallons more fuel capacity than the GX (22.5 vs. 21.1 gallons), for longer range between fill-ups.

For better stopping power the Q7 55 TFSI’s front brake rotors are larger than those on the GX:

The Q7 stops much shorter than the GX:

For better traction, the Q7’s optional tires are larger than the largest tires available on the GX (285/45R20 vs. 265/55R20).

The Q7’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the GX Overtrail’s standard 70 series tires. The Q7’s optional tires have a lower 40 series profile than the GX’s optional 50 series tires.

For better ride, handling and brake cooling the Q7 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the GX Overtrail.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the Q7 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The GX doesn’t offer run-flat tires.

For a smoother ride and more stable handling, the Q7’s wheelbase is 5.7 inches longer than on the GX (117.9 inches vs. 112.2 inches).

The Q7 Prestige handles at .86 G’s, while the GX Overtrail+ pulls only .71 G’s of cornering force in a Car and Driver skidpad test.

The Q7 Premium Plus executes Motor Trend’s “Figure Eight” maneuver 2.5 seconds quicker than the GX Luxury+ (26.4 seconds @ .68 average G’s vs. 28.9 seconds @ .59 average G’s).

The Audi Q7 may be more efficient, handle and accelerate better because it weighs about 550 to 650 pounds less than the Lexus GX.

The Q7 is 7 inches shorter in height than the GX, making the Q7 much easier to wash and garage and drive (lower center of gravity).

Unibody construction lowers the Q7’s center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The GX doesn’t use unibody construction, but a body-on-frame design.

The design of the Audi Q7 amounts to more than styling. The Q7 has an aerodynamic coefficient of drag of .36 Cd (optional .34 Cd with 55 TFSI). That is significantly lower than the GX (.399). A more efficient exterior helps keep the interior quieter and helps the Q7 get better fuel mileage.

The Q7’s cargo area provides more volume than the GX.

Unlike the driver-only memory system in the GX, the Q7 Prestige has a passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Q7’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the GX.

Heated windshield washer nozzles are standard on the Q7 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The GX doesn’t offer heated windshield washer nozzles.

Laser headlights, optional on the Q7 Prestige, produce their light by firing blue lasers through phosphorus, a process that uses one-half the power of the GX’s LED headlights. Laser headlights can have double the range of LEDs with a much smaller surface area.

To better shield the driver and front passenger’s vision, the Q7 has standard dual-element sun visors that can block glare from two directions simultaneously. The GX doesn’t offer secondary sun visors.

A manual rear sunshade and rear side window sunshades are optional in the Q7 (except Premium) to help block heat and glare for the rear passengers. The GX doesn’t offer a rear sunshade.

The Q7 55 TFSI Prestige’s Park Assist Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Park Assist Plus will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The GX doesn’t offer an automated parking system.
