The Range Rover Sport’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The QX50 doesn’t offer pre-crash pretensioners.

Both the Range Rover Sport and QX50 have child safety locks to prevent children from opening the rear doors. The Range Rover Sport 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 QX50’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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Range Rover Sport. But it costs extra on the QX50.

The Range Rover Sport’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The QX50 doesn’t offer a driver alert monitor.

Both the Range Rover Sport and the QX50 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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 and rear cross-path warning.

The Land Rover Range Rover Sport weighs 810 to 2011 pounds more than the Infiniti QX50. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Reliability

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Land Rover vehicles are better in initial quality than Infiniti vehicles. With 11 fewer problems per 100 vehicles, JD Power ranks Land Rover higher than Infiniti.

Engine

The Range Rover Sport P360’s standard 3.0 turbo/supercharged 6-cylinder hybrid produces 87 more horsepower (355 vs. 268) and 85 lbs.-ft. more torque (365 vs. 280) than the QX50’s 2.0 turbo 4-cylinder. The Range Rover Sport P400’s standard 3.0 turbo/supercharged 6-cylinder hybrid produces 127 more horsepower (395 vs. 268) and 126 lbs.-ft. more torque (406 vs. 280) than the QX50’s 2.0 turbo 4-cylinder. The Range Rover Sport P440e’s standard 3.0 turbo/supercharged 6-cylinder hybrid produces 166 more horsepower (434 vs. 268) and 177 lbs.-ft. more torque (457 vs. 280) than the QX50’s 2.0 turbo 4-cylinder. The Range Rover Sport P530’s standard 4.4 turbo V8 produces 255 more horsepower (523 vs. 268) and 273 lbs.-ft. more torque (553 vs. 280) than the QX50’s 2.0 turbo 4-cylinder.

Fuel Economy and Range

The Range Rover Sport P440e can travel with zero emissions for 48 miles. The QX50 can’t move without running its internal combustion engine.

Regenerative brakes improve the Range Rover Sport’s fuel efficiency by converting inertia back into energy instead of wasting it. The QX50 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the Range Rover Sport’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 QX50 doesn’t offer an automatic engine start/stop system.

The Range Rover Sport P440e’s standard fuel tank has 2.9 gallons more fuel capacity than the QX50 (18.9 vs. 16 gallons), for longer range between fill-ups. The Range Rover Sport’s standard fuel tank has 7.8 gallons more fuel capacity than the QX50 (23.8 vs. 16 gallons).

Transmission

The Range Rover Sport’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The QX50 doesn’t offer launch control.

Brakes and Stopping

For better stopping power the Range Rover Sport’s brake rotors are larger than those on the QX50:

	Range Rover Sport	QX50
Front Rotors	14.9 inches	13 inches
Rear Rotors	13.9 inches	12.1 inches

Tires and Wheels

For better traction, the Range Rover Sport has larger standard tires than the QX50 (275/50R21 vs. 235/55R19). The Range Rover Sport’s optional tires are larger than the largest tires available on the QX50 (285/45R23 vs. 255/45R20).

The Range Rover Sport’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the QX50’s standard 55 series tires.

For better ride, handling and brake cooling the Range Rover Sport has standard 21-inch wheels. Smaller 19-inch wheels are standard on the QX50. The Range Rover Sport’s optional 23-inch wheels are larger than the 20-inch wheels on the QX50 Sport/Sensory/Autograph.

The Range Rover Sport offers an optional full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the QX50; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

Suspension and Handling

The Range Rover Sport Autobiography/First Edition has active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The QX50 doesn’t offer an active sway bar system.

The front and rear suspension of the Range Rover Sport uses air springs for a smoother, controlled ride than the QX50, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The Range Rover Sport Autobiography/First Edition offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Infiniti doesn’t offer an active suspension on the QX50.

The Range Rover Sport has a standard driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The QX50’s suspension doesn’t offer adjustable shock absorbers.

The Range Rover Sport has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Range Rover Sport’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The QX50 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Range Rover Sport’s wheelbase is 7.8 inches longer than on the QX50 (118 inches vs. 110.2 inches).

For better handling and stability, the track (width between the wheels) on the Range Rover Sport is 2.6 inches wider in the front and 3 inches wider in the rear than the average track on the QX50.

For greater off-road capability the Range Rover Sport has a 2.5 inches greater minimum ground clearance than the QX50 (11.1 vs. 8.6 inches), allowing the Range Rover Sport to travel over rougher terrain without being stopped or damaged.

Chassis

The design of the Land Rover Range Rover Sport amounts to more than styling. The Range Rover Sport has an aerodynamic coefficient of drag of .29 Cd. That is lower than the QX50 (.32) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Range Rover Sport get better fuel mileage.

Cargo Capacity

The Range Rover Sport has a larger cargo volume than the QX50 with its rear seat up (31.9 vs. 31.4 cubic feet).

The Range Rover Sport’s cargo area is larger than the QX50’s in almost every dimension:

	Range Rover Sport	QX50
Length to seat (2nd/1st)	38.2”/71.9”	39”/71.7”
Max Width	55.2”	54.5”
Min Width	43.5”	41.5”
Height	33.3”	31.2”

Towing

The Range Rover Sport’s standard towing capacity is much higher than the QX50’s (7716 vs. 0 pounds).

Standard Trailer Stability Assist (TSA) on the Range Rover Sport uses the Dynamic 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 QX50 doesn’t offer electronic trailer sway control.

Servicing Ease

The engine in the Range Rover Sport is mounted longitudinally (North-South), instead of sideways, as in the QX50. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

Unlike the driver-only memory system in the QX50 Luxe/Sport/Sensory/Autograph, the Range Rover Sport has standard driver and 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 power windows standard on both the Range Rover Sport and the QX50 have locks to prevent small children from operating them. When the lock on the Range Rover Sport is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX50 prevents the driver from operating the other windows just as it does the other passengers.

The Range Rover Sport’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 QX50’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

Heated windshield washer nozzles are optional on the Range Rover Sport to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The QX50 doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Range Rover Sport has standard headlight washers to keep headlight output high. The QX50 doesn’t offer headlight washers.

To better shield the driver and front passenger’s vision, the Range Rover Sport offers optional dual-element sun visors that can block glare from two directions simultaneously. The QX50 doesn’t offer secondary sun visors.

A manual rear sunshade is standard in the Range Rover Sport to help block heat and glare for the rear passengers. The QX50 doesn’t offer a rear sunshade.

Optional air conditioned front and rear seats keep the Range Rover Sport’s passengers comfortable and take the sting out of hot leather in summer. The QX50 doesn’t offer air-conditioned seats in the rear.

The Range Rover Sport Autobiography/First Edition has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the QX50.

The Range Rover Sport offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The QX50 doesn’t offer a house-current electrical outlet.

The Range Rover Sport’s optional Park Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The QX50 doesn’t offer an automated parking system.

Recommendations

The Land Rover Range Rover Sport outsold the Infiniti QX50 by 53% during the 2022 model year.
