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 RX doesn’t offer pre-crash pretensioners.

Both the Range Rover Sport and RX 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 RX’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 RX.

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 RX doesn’t offer a driver alert monitor.

Both the Range Rover Sport and the RX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front 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 Range Rover Sport has more powerful engines than the RX:

The Range Rover Sport P440e can travel with zero emissions for 48 miles. The RX 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 RX doesn’t offer a regenerative braking system.

The Range Rover Sport P440e’s standard fuel tank has 1.7 gallons more fuel capacity than the RX 350h/500h’s standard fuel tank (18.9 vs. 17.2 gallons), for longer range between fill-ups. The Range Rover Sport’s standard fuel tank has 6 gallons more fuel capacity than the RX 350’s standard fuel tank (23.8 vs. 17.8 gallons).

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

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

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 RX 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 RX, 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. Lexus doesn’t offer an active suspension on the RX.

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 RX doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Range Rover Sport’s wheelbase is 5.8 inches longer than on the RX (118 inches vs. 112.2 inches).

For better handling and stability, the track (width between the wheels) on the Range Rover Sport is 1.8 inches wider in the front and .5 inches wider in the rear than on the RX.

For greater off-road capability the Range Rover Sport has a 3 inches greater minimum ground clearance than the RX 350 (11.1 vs. 8.1 inches), allowing the Range Rover Sport to travel over rougher terrain without being stopped or damaged. The Range Rover Sport’s minimum ground clearance is 2.9 inches higher than on the RX 350h (11.1 vs. 8.2 inches).

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 significantly lower than the RX (.35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Range Rover Sport get better fuel mileage.

The Range Rover Sport uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The RX doesn’t offer active noise cancellation.

The Range Rover Sport has .1 inches more rear headroom and .4 inches more rear legroom than the RX.

The Range Rover Sport has a much larger cargo volume than the RX with its rear seat up (31.9 vs. 29.6 cubic feet).

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

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

The Range Rover Sport has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The RX doesn’t offer a remote starting system.

Unlike the driver-only memory system in the RX Premium/Luxury/500h F Sport, 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.

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 RX doesn’t offer heated windshield washer nozzles.

To improve rear visibility by keeping the rear window clear, the Range Rover Sport has a standard rear wiper. The RX doesn’t offer a rear wiper.

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

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 RX.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Land Rover Range Rover Sport has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the RX.
