Compare the2025 BMW X6VS 2025 Lexus RX

The X6’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.

The X6 has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The RX doesn’t offer a whiplash protection system.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the BMW X6 achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Lexus RX has not been tested.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the X6. But it costs extra on the RX.

When descending a steep, off-road slope, the X6’s standard Hill Descent Control allows you to creep down safely. The RX doesn’t offer Hill Descent Control.

Both the X6 and the RX have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, 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 X6’s corrosion warranty is 6 years longer than the RX’s (12 vs. 6 years).

BMW pays for scheduled maintenance on the X6 for 2 years and 26000 miles longer than Lexus pays for maintenance for the RX (3/36,000 vs. 1/10,000).

There are over 43 percent more BMW dealers than there are Lexus dealers, which makes it easier should you ever need service under the X6’s warranty.

The X6 has more powerful engines than the RX:

Both the X6 and the RX have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stoplights and heavy traffic. All X6s have a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily. The RX 350h/500h doesn’t offer a way to disable start/stop.

The X6 has 7.4 gallons more fuel capacity than the RX 450+’s standard fuel tank (21.9 vs. 14.5 gallons), for longer range between fill-ups. The X6 has 4.1 gallons more fuel capacity than the RX 350’s standard fuel tank (21.9 vs. 17.8 gallons).

The X6’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 RX doesn’t offer launch control.

For better stopping power the X6’s standard brake rotors are larger than those on the RX:

For better traction, the X6 has larger standard tires than the RX (275/45R20 vs. 235/60R19). The X6’s optional tires are larger than the largest tires available on the RX (F:275/40R21 & R:315/35R21 vs. 235/60R19).

The X6’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the RX’s standard 60 series tires. The X6’s optional 275/35R22 front and 315/30R22 rear tires have a lower 35 series front and 30 series rear profile than the RX’s optional 50 series tires.

For better ride, handling and brake cooling the X6 has standard 20-inch wheels. Smaller 19-inch wheels are standard on the RX. The X6’s optional 22-inch wheels are larger than the 21-inch wheels optional on the RX.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the X6 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The RX doesn’t offer run-flat tires.

The X6 M60i offers 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 X6 M60i xDrive 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 X6 has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The RX doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the X6’s wheelbase is 4.9 inches longer than on the RX (117.1 inches vs. 112.2 inches).

For better handling and stability, the average track (width between the wheels) on the X6 is 1.1 inches wider in the front and .5 inches wider in the rear than the track on the RX.

The X6’s front to rear weight distribution is more even (50.6% to 49.4%) than the RX’s (54.7% to 45.3%). This gives the X6 more stable handling and braking.

For greater off-road capability the X6 has a greater minimum ground clearance than the RX 350 (8.5 vs. 8.1 inches), allowing the X6 to travel over rougher terrain without being stopped or damaged. The X6’s minimum ground clearance is .3 inch higher than on the RX 350h (8.5 vs. 8.2 inches).

The front grille of the X6 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The RX doesn’t offer active grille shutters.

The X6 has 1.9 inches more front shoulder room and 1.2 inches more rear shoulder room than the RX.

The X6 has a larger cargo volume with its rear seat folded than the RX with its rear seat folded (59.6 vs. 46.2 cubic feet).

The engine in the X6 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.

Heated windshield washer nozzles are standard on the X6 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.

Manual rear side window sunshades are available in the X6 to help block heat and glare for the rear passengers. The RX doesn’t offer rear side window sunshades.

The X6 offers optional 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 BMW X6 has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the RX.
