Both the Q7 and GX460 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 GX460’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.

The Q7 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The GX460 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The Q7 offers an optional backup collision prevention system that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The GX460 doesn’t offer backup collision prevention brakes.

A passive infrared night vision system optional on the Q7 Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The GX460 doesn’t offer a night vision system.

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 GX460 uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the Q7 and the GX460 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, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Q7 the rating of “Top Pick” for 2017, a rating granted to only 185 vehicles tested by the IIHS. The GX460 has not been tested, yet.

A hardened steel chain, with no maintenance needs, drives the camshafts in the Q7’s engine. A rubber cam drive belt that needs periodic replacement drives the GX460’s camshafts. If the GX460’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

On the EPA test cycle the Q7 55 TFSI gets better fuel mileage than the GX460 (17 city/21 hwy vs. 15 city/19 hwy).

On the EPA test cycle the Q7 45 TFSI gets better fuel mileage than the GX460 (19 city/25 hwy vs. 15 city/19 hwy).

Regenerative brakes improve the Q7 55 TFSI’s fuel efficiency by converting inertia back into energy instead of wasting it. The GX460 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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The GX460 doesn’t offer an automatic engine start/stop system.

For better traction, the Q7’s optional tires are larger than the largest tires available on the GX460 (285/45R20 vs. 265/60R18).

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 GX460’s standard 60 series tires. The Q7 Prestige’s optional tires have a lower 35 series profile than the GX460’s 60 series tires.

For better ride, handling and brake cooling the Q7 has standard 19-inch wheels. Only 18-inch wheels are available on the GX460. The Q7 Prestige offers optional 22-inch wheels.

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 GX460 doesn’t offer run-flat tires.

Suspension and Handling

For superior ride and handling, the Audi Q7 has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Lexus GX460 has a solid rear axle, with a non-independent rear suspension.

For a smoother ride and more stable handling, the Q7’s wheelbase is 8.1 inches longer than on the GX460 (117.9 inches vs. 109.8 inches).

For better handling and stability, the track (width between the wheels) on the Q7 is 3.7 inches wider in the front and 4.2 inches wider in the rear than on the GX460.

The Q7 Prestige handles at .86 G’s, while the GX460 pulls only .74 G’s of cornering force in a Car and Driver skidpad test.

The Q7 Premium Plus executes Motor Trend’s “Figure Eight” maneuver 1.9 seconds quicker than the GX460 (26.4 seconds @ .68 average G’s vs. 28.3 seconds @ .58 average G’s).

For greater off-road capability the Q7 has a greater minimum ground clearance than the GX460 (8.3 vs. 8.1 inches), allowing the Q7 to travel over rougher terrain without being stopped or damaged. The Q7 w/Air Suspension’s minimum ground clearance is 1.6 inches higher than on the GX460 (9.7 vs. 8.1 inches).

The Audi Q7 may be more efficient, handle and accelerate better because it weighs about 100 to 350 pounds less than the Lexus GX460.

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 GX460 uses body-on-frame design instead.

A low lift-over cargo hatch design makes loading and unloading the Q7 easier. The Q7’s cargo hatch lift-over height is 32.5 inches, while the GX460’s liftover is 33.8 inches.

The Q7’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The GX460’s swing out door blocks loading from the passenger’s side.

To make loading and unloading groceries and cargo easier when your hands are full, the Q7’s power cargo door can be opened or closed just by waving your foot, leaving your hands completely free. The GX460 doesn’t offer a power or hands-free opening cargo door.

Unlike the driver-only memory system in the GX460, the Q7 Prestige offers an optional 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 Prestige has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The GX460 doesn’t offer a heads-up display.

The Q7’s power parking brake sets with one touch and releases with one touch or automatically. The GX460’s parking brake has to released manually.

The Q7’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The GX460’s cruise control switches are unlit, making them difficult to find at night and operate safely.

The Q7’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The GX460’s standard manually variable intermittent wipers have to be constantly adjusted.

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 GX460 doesn’t offer a rear sunshade.

The Q7’s power mirror controls are mounted on the armrest for easy access. The GX460’s power mirror controls are on the dash where they are possibly hidden by the steering wheel and are awkward to manipulate.

The Q7 Prestige offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the GX460.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi Q7 offers an optional wireless phone charging system (Qi) in the center console. The GX460 doesn’t offer wireless personal charging.
