Safety

The X7’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The RXL doesn’t offer pre-crash pretensioners.

The X7 has standard Post-Crash Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The RXL 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the X7. But it costs extra on the RXL.

The X7’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 RXL doesn’t offer a driver alert monitor.

Both the X7 and the RXL have standard driver and passenger frontal 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 and available around view monitors.

The BMW X7 weighs 465 to 1153 pounds more than the Lexus RXL. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Warranty

The X7’s corrosion warranty is 6 years longer than the RXL’s (12 vs. 6 years).

BMW pays for scheduled maintenance on the X7 for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Lexus only pays for the first scheduled maintenance visit on the RXL.

There are over 43 percent more BMW dealers than there are Lexus dealers, which makes it easier should you ever need service under the X7’s warranty.

Engine

The X7 xDrive40i’s standard 3.0 turbo 6 cyl. produces 45 more horsepower (335 vs. 290) and 67 lbs.-ft. more torque (330 vs. 263) than the RX 350L’s standard 3.5 DOHC V6. The X7 xDrive40i’s 3.0 turbo 6 cyl. produces 27 more horsepower (335 vs. 308) than the RX 450hL’s standard 3.5 DOHC V6 hybrid. The X7 xDrive50i’s standard 4.4 turbo V8 produces 148 more horsepower (456 vs. 308) than the RX 450hL’s standard 3.5 DOHC V6 hybrid.

Fuel Economy and Range

On the EPA test cycle the X7 xDrive40i gets better fuel mileage than the RX 350L AWD (20 city/25 hwy vs. 18 city/25 hwy).

Regardless of its engine, regenerative brakes improve the X7’s fuel efficiency by converting inertia back into energy instead of wasting it. Lexus only offers a regenerative brake system on the RXL Hybrid.

Regardless of its engine, the X7’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 RXL Hybrid.

The X7 has 4.7 gallons more fuel capacity than the RXL Hybrid’s standard fuel tank (21.9 vs. 17.2 gallons), for longer range between fill-ups. The X7 has 2.7 gallons more fuel capacity than the RXL’s standard fuel tank (21.9 vs. 19.2 gallons).

Transmission

The X7’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 RXL doesn’t offer launch control.

Tires and Wheels

For better traction, the X7 has larger standard tires than the RXL (F:275/40R22 & R:315/35R22 vs. 235/65R18). The X7’s tires are larger than the largest tires available on the RXL (285/45R21 vs. 235/65R18).

The X7’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 RXL’s standard 65 series tires. The X7’s optional 275/40R22 front and 315/35R22 rear tires have a lower 40 series front and 35 series rear profile than the RXL’s optional 55 series tires.

For better ride, handling and brake cooling the X7 has standard 21-inch wheels. Smaller 18-inch wheels are standard on the RXL. The X7’s optional 22-inch wheels are larger than the 20-inch wheels optional on the RXL.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X7 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The RXL doesn’t offer run-flat tires.

Suspension and Handling

The front and rear suspension of the X7 uses air springs for a smoother, controlled ride than the RXL, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The X7 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The X7’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 RXL doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the X7’s wheelbase is 12.4 inches longer than on the RXL (122.2 inches vs. 109.8 inches).

For better handling and stability, the track (width between the wheels) on the X7 is 1.9 inches wider in the front and 3.1 inches wider in the rear than on the RXL.

For greater off-road capability the X7 has a greater minimum ground clearance than the RXL (8.7 vs. 8.2 inches), allowing the X7 to travel over rougher terrain without being stopped or damaged.

Chassis

The front grille of the X7 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The RXL doesn’t offer active grille shutters.

Passenger Space

The X7 has 2.1 inches more front headroom, 1.7 inches more front shoulder room, .2 inches more rear headroom, 6.7 inches more rear legroom, .3 inches more rear shoulder room, 2.2 inches more third row headroom, 9.8 inches more third row legroom and 2.2 inches more third row shoulder room than the RXL.

Cargo Capacity

The X7’s cargo area provides more volume than the RXL.

The X7’s rear cargo window opens separately from the rest of the tailgate door to allow quicker loading of small packages. The RXL’s rear cargo window doesn’t open.

Towing

The X7’s standard towing capacity is much higher than the RXL’s (7500 vs. 0 pounds).

Servicing Ease

The engine in the X7 is mounted longitudinally (North-South), instead of sideways, as in the RXL. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

Ergonomics

Unlike the driver-only memory system in the RXL, the X7 offers an optional 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.

The X7’s optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The RXL doesn’t offer an automated parking system.
