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 Series doesn’t offer pre-crash pretensioners.

The X6 has standard PostCrash iBrake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The RX Series doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

A passive infrared night vision system optional on the X6 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The RX Series doesn’t offer a night vision system.

Both the X6 and the RX Series 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, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors, available all-wheel drive and around view monitors.

The X6’s corrosion warranty is 6 years longer than the RX Series’ (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 Series (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.

On the EPA test cycle the X6 s/xDrive40i xDrive gets better city fuel mileage than the RX 350 AWD (20 city/26 hwy vs. 19 city/26 hwy).

Regardless of its engine, regenerative brakes improve the X6’s fuel efficiency by converting inertia back into energy instead of wasting it. Lexus only offers a regenerative brake system on the RX Series Hybrid.

Regardless of its engine, the X6’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Lexus only offers an automatic engine start/stop system on the RX Series Hybrid.

The X6 has 4.7 gallons more fuel capacity than the RX Series Hybrid’s standard fuel tank (21.9 vs. 17.2 gallons), for longer range between fill-ups. The X6 has 2.7 gallons more fuel capacity than the RX Series’ standard fuel tank (21.9 vs. 19.2 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 Series doesn’t offer launch control.

For better traction, the X6 has larger standard tires than the RX Series (275/45R20 vs. 235/65R18). The X6’s optional tires are larger than the largest tires available on the RX Series (F:275/40R21 & R:315/35R21 vs. 235/65R18).

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 Series’ standard 65 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 Series’ optional 55 series tires.

For better ride, handling and brake cooling the X6 has standard 20-inch wheels. Smaller 18-inch wheels are standard on the RX Series. The X6’s optional 22-inch wheels are larger than the 20-inch wheels optional on the RX Series.

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 Series doesn’t offer run-flat tires.

Suspension and Handling

The X6 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 Series doesn’t offer an active sway bar system.

The X6 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 Series.

For a smoother ride and more stable handling, the X6’s wheelbase is 7.3 inches longer than on the RX Series (117.1 inches vs. 109.8 inches).

For better handling and stability, the average track (width between the wheels) on the X6 is 1.8 inches wider in the front and 2.7 inches wider in the rear than the track on the RX Series.

The X6’s front to rear weight distribution is more even (50% to 50%) than the RX Series’ (57% to 43%). This gives the X6 more stable handling and braking.

For greater off-road capability the X6 Air Suspension has a 1.5 inches greater minimum ground clearance than the RX Series (9.7 vs. 8.2 inches), allowing the X6 to travel over rougher terrain without being stopped or damaged.

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 Series doesn’t offer active grille shutters.

The engine in the X6 is mounted longitudinally (North-South), instead of sideways, as in the RX Series. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

Unlike the driver-only memory system optional at extra cost in the RX Series, the X6 M50i has a passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

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 Series doesn’t offer heated windshield washer nozzles.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW X6 offers an optional wireless phone charging system (Qi) in the center console. The RX Series doesn’t offer wireless personal charging.

The X6’s optional Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The RX Series doesn’t offer an automated parking system.
