Compare the2023 Infiniti QX60VS 2023 Lexus GX

The QX60 Autograph has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The GX doesn’t offer front seat center airbags.

Over 200 people are killed each year when backed over by motor vehicles. The QX60 has standard Rear Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GX doesn’t offer backup collision prevention brakes.

For better protection of the passenger compartment, the QX60 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 QX60 and the GX have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive, around view monitors and driver alert monitors.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the QX60 its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 29 vehicles tested by the IIHS. The GX has not been tested, yet.

The QX60 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The GX’s 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

The QX60’s corrosion warranty is 1 year longer than the GX’s (7 vs. 6 years).

Infiniti pays for scheduled maintenance on the QX60 for 2 years and 26000 miles longer than Lexus pays for maintenance for the GX (3/36,000 vs. 1/10,000).

A hardened steel chain, with no maintenance needs, drives the camshafts in the QX60’s engine. A rubber cam drive belt that needs periodic replacement drives the GX’s camshafts. If the GX’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

As tested in Car and Driver the Infiniti QX60 is faster than the Lexus GX:

On the EPA test cycle the QX60 gets better mileage than the GX:

In heavy traffic or at stoplights the QX60’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.

To lower fuel costs and make buying fuel easier, the Infiniti QX60 uses regular unleaded gasoline (premium recommended for maximum performance). The GX requires premium, which can cost 20 to 55 cents more per gallon.

The QX60 has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The GX doesn’t offer a cap-less fueling system.

A nine-speed automatic is standard on the Infiniti QX60, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the GX.

For better stopping power the QX60’s brake rotors are larger than those on the GX:

The QX60 stops much shorter than the GX:

The QX60 Luxe/Sensory/Autograph’s tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the GX’s optional 55 series tires.

For better ride, handling and brake cooling the QX60 Luxe/Sensory/Autograph has standard 20-inch wheels. The GX’s largest wheels are only 19-inches.

The QX60 has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The GX doesn’t offer vehicle monitored tire inflation.

For superior ride and handling, the Infiniti QX60 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 GX has a solid rear axle, with a non-independent rear suspension.

For a smoother ride and more stable handling, the QX60’s wheelbase is 4.4 inches longer than on the GX (114.2 inches vs. 109.8 inches).

For better handling and stability, the track (width between the wheels) on the QX60 is 4.5 inches wider in the front and 4.5 inches wider in the rear than on the GX.

The QX60 Autograph AWD handles at .85 G’s, while the GX pulls only .74 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the QX60’s turning circle is 2.4 feet tighter than the GX’s (38.7 feet vs. 41.1 feet).

The Infiniti QX60 may be more efficient, handle and accelerate better because it weighs about 550 to 750 pounds less than the Lexus GX.

Unibody construction lowers the QX60’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 uses body-on-frame design instead.

The design of the Infiniti QX60 amounts to more than styling. The QX60 has an aerodynamic coefficient of drag of .32 Cd. That is lower than the GX (.35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the QX60 get better fuel mileage.

The QX60 has 10.9 cubic feet more passenger volume than the GX (140.6 vs. 129.7).

The QX60 has 2.8 inches more front headroom, .4 inches more front legroom, 2.3 inches more front hip room, 5.2 inches more front shoulder room, 3.6 inches more rear legroom, 1.5 inches more rear hip room, 2.4 inches more rear shoulder room, .5 inches more third row headroom, 2.1 inches more third row hip room and 1.1 inches more third row shoulder room than the GX.

The QX60’s cargo area provides more volume than the GX.

The QX60’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The GX’s swing out door blocks loading from the passenger’s side.

To make loading and unloading groceries and cargo easier, especially for short adults, the QX60 has a standard power liftgate, which opens and closes automatically by pressing a button, or on the QX60 Sensory/Autograph, by just kicking your foot under the back bumper, completely leaving your hands free. The GX doesn’t offer a power cargo door.

Unlike the driver-only memory system in the GX, the QX60 Sensory/Autograph has a passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position (with optional power wheel adjuster), outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The QX60 (except Pure) offers an available heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The GX doesn’t offer a heads-up display.

The QX60’s power parking brake sets with one touch and releases with one touch or automatically. The GX’s parking brake has to be released manually.

The QX60’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 GX’s cruise control switches are unlit, making them difficult to find at night and operate safely.

The QX60’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 GX’s standard manually variable intermittent wipers have to be constantly adjusted.

The QX60’s power mirror controls are mounted on the armrest for easy access. The GX’s power mirror controls are on the dash where they are possibly hidden by the steering wheel and are awkward to manipulate.

The QX60 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the GX.

The QX60 Sensory/Autograph has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the GX.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Infiniti QX60 has a standard wireless phone charging system (Qi) in the center console. The GX doesn’t offer wireless personal charging.

The QX60 is available in both front-wheel drive and four-wheel drive configurations. The GX doesn’t offer a two-wheel drive configuration.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Infiniti QX60 will be $2197 to $7908 less than for the Lexus GX.

J.D. Power and Associates rated the QX60 first among midsize premium suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The GX isn’t in the top three.
