Compare the2026 Lexus GXVS 2026 Audi SQ8

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the GX are reminded to check the back seat if they opened the rear door before starting out. The SQ8 doesn’t offer a back seat reminder.

The Lexus GX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The SQ8 doesn’t offer knee airbags.

Both the GX and the SQ8 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 National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Lexus GX is safer than the Audi SQ8:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Lexus’ powertrain warranty covers the GX 2 years and 20,000 miles longer than Audi covers the SQ8. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the SQ8 ends after only 4 years or 50,000 miles.

The SQ8’s redline is at 6800 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The GX has a 5800 RPM redline.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Lexus GX higher (5 out of 10) than the Audi SQ8 (2). This means the GX produces up to 20.8 pounds less smog-producing pollutants than the SQ8 every 15,000 miles.

A 10-speed automatic is standard on the Lexus GX, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the SQ8.

The Lexus GX’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Audi SQ8 only has 5 wheel lugs per wheel.

The GX has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the SQ8; it requires you to depend on a temporary spare, which limits mileage and speed before replacement.

The GX has standard seating for 7 passengers; the SQ8 can only carry 5.

The GX’s cargo area provides more volume than the SQ8.

The GX’s rear cargo window opens separately from the rest of the liftgate door to allow quicker loading of small packages. The SQ8’s rear cargo window doesn’t open.

The GX’s standard towing capacity is much higher than the SQ8’s (9063 vs. 7700 pounds). Maximum trailer towing in the Audi SQ8 is only 7700 pounds. The GX offers up to a 9096 lbs. towing capacity.

Standard Trailer Sway Control on the GX uses the Vehicle Stability Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The SQ8 doesn’t offer electronic trailer sway control.

The GX’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The SQ8 does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the GX has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the SQ8 only has an intermittent setting, so in a hard rain visibility isn’t as good.

The GX has a 115-volt a/c outlet in the cargo area, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The SQ8 doesn’t offer a house-current electrical outlet.

The Lexus GX outsold the Audi Q8/SQ8/RS Q8 by over three to one during 2025.
