Both the Range Rover Sport and GX 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 GX’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.

Both the Range Rover Sport and GX have rear cross-traffic warning, but the Range Rover Sport has Rear Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The GX’s Rear Cross-Traffic Alert doesn’t automatically brake.

For better protection of the passenger compartment, the Range Rover Sport 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 Range Rover Sport and the GX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.

Reliability

A hardened steel chain, with no maintenance needs, drives the camshafts in the Range Rover Sport’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.

Engine

The Range Rover Sport P360’s standard 3.0 turbo/supercharged 6-cylinder hybrid produces 54 more horsepower (355 vs. 301) and 40 lbs.-ft. more torque (369 vs. 329) than the GX’s 4.6 DOHC V8. The Range Rover Sport P400’s standard 3.0 turbo/supercharged 6-cylinder hybrid produces 94 more horsepower (395 vs. 301) and 77 lbs.-ft. more torque (406 vs. 329) than the GX’s 4.6 DOHC V8. The Range Rover Sport P550e’s standard 3.0 turbo/supercharged 6-cylinder hybrid produces 242 more horsepower (543 vs. 301) and 261 lbs.-ft. more torque (590 vs. 329) than the GX’s 4.6 DOHC V8. The Range Rover Sport SV’s standard 4.4 turbo V8 hybrid produces 325 more horsepower (626 vs. 301) and 224 lbs.-ft. more torque (553 vs. 329) than the GX’s 4.6 DOHC V8.

		4.4 turbo V8 Hybrid	16 city/22 hwy
GX
	AWD	4.6 DOHC V8	15 city/19 hwy

The Range Rover Sport P550e can travel with zero emissions for 51 miles. The GX 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 GX 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 GX doesn’t offer an automatic engine start/stop system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Land Rover Range Rover Sport higher (6 to 7 out of 10) than the Lexus GX (3). This means the Range Rover Sport produces up to 24.5 pounds less smog-producing pollutants than the GX every 15,000 miles.

Transmission

An eight-speed automatic is standard on the Land Rover Range Rover Sport, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the GX.

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 GX 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 GX:

	Range Rover Sport	Range Rover Sport SV	GX
Front Rotors	14.9 inches	17.3 inches	13.3 inches
Rear Rotors	13.9 inches	15.3 inches	12.3 inches

The Range Rover Sport SV offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The GX doesn’t offer ceramic brake rotors.

The Range Rover Sport stops shorter than the GX:

	Range Rover Sport	GX
60 to 0 MPH	133 feet	136 feet	Consumer Reports

Tires and Wheels

For better traction, the Range Rover Sport has larger standard tires than the GX (275/50R21 vs. 265/60R18). The Range Rover Sport SV’s tires are larger than the largest tires available on the GX (F:285/40R23 & R:305/35R23 vs. 265/60R18).

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 GX’s standard 60 series tires. The Range Rover Sport SV’s 285/40R23 front and 305/35R23 rear tires have a lower 40 series front and 35 series rear profile than the GX’s optional 55 series tires.

For better ride, handling and brake cooling the Range Rover Sport has standard 21-inch wheels. Smaller 18-inch wheels are standard on the GX. The Range Rover Sport’s optional 23-inch wheels are larger than the 19-inch wheels optional on the GX.

Suspension and Handling

For superior ride and handling, the Land Rover Range Rover Sport 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.

The front and rear suspension of the Range Rover Sport uses air springs for a smoother, controlled ride than the GX, 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 GX.

For a smoother ride and more stable handling, the Range Rover Sport’s wheelbase is 8.2 inches longer than on the GX (118 inches vs. 109.8 inches).

For better handling and stability, the track (width between the wheels) on the Range Rover Sport is 4.6 inches wider in the front and 4.7 inches wider in the rear than on the GX.

The Range Rover Sport SE handles at .81 G’s, while the GX pulls only .74 G’s of cornering force in a Car and Driver skidpad test.

The Range Rover Sport Autobiography executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the GX (27.2 seconds @ .66 average G’s vs. 28.3 seconds @ .58 average G’s).

For better maneuverability, the Range Rover Sport w/Rear Wheel Steering’s turning circle is 5.2 feet tighter than the GX’s (35.9 feet vs. 41.1 feet).

For greater off-road capability the Range Rover Sport SV has a 1.7 inches greater minimum ground clearance than the GX (9.8 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 GX (11 vs. 8.1 inches).

Chassis

Unibody construction lowers the Range Rover Sport’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 doesn’t use unibody construction, but a body-on-frame design.

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 GX (.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 GX doesn’t offer active noise cancellation.

As tested by Car and Driver while at idle, the interior of the Range Rover Sport SE is quieter than the GX (41 vs. 43 dB).

Passenger Space

The Range Rover Sport has 1.3 inches more front headroom and 3.7 inches more rear legroom than the GX.

Cargo Capacity

The Range Rover Sport has a much larger cargo volume than the GX with its rear seat up (31.9 vs. 11.6 cubic feet).

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

	Range Rover Sport	GX
Length to seat (3rd/2nd/1st)	38.2”/71.9”	7.2”/36.5”/72”
Max Width	55.2”	50.7”
Min Width	43.5”	43.4”
Height	33.3”	35.1”

The Range Rover Sport’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 Range Rover Sport has a standard power liftgate, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The GX doesn’t offer a power cargo door.

Towing

The Range Rover Sport’s standard towing capacity is much higher than the GX’s (7716 vs. 6500 pounds).

Ergonomics

Unlike the driver-only memory system in the GX, 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 Range Rover Sport offers an optional 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 Range Rover Sport’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 Range Rover Sport’s standard Passive Keyless Entry allows you to unlock the doors from any outside door handle, open the cargo door, and start the vehicle, all without removing the key from the pocket or purse. Smart Access standard on the GX doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

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

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 GX doesn’t offer heated windshield washer nozzles.

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 GX doesn’t offer secondary sun visors.

Manual rear side window sunshades are available in the Range Rover Sport to help block heat and glare for the rear passengers. The GX doesn’t offer rear side window sunshades.

The Range Rover Sport has standard front air conditioned seats and offers them optionally in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The GX doesn’t offer air-conditioned seats for the second row.

The Range Rover Sport 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 Range Rover Sport Autobiography/SV 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 Land Rover Range Rover Sport has a standard wireless phone charging system (Qi) in the center console. The GX doesn’t offer wireless personal charging.

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 GX doesn’t offer an automated parking system.
