The X5 xDrive45e’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 X5 xDrive45e has a standard PostCrash iBrake, which automatically applies 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 X5 xDrive45e. But it costs extra on the RXL.
Both the X5 xDrive45e and the RXL have standard driver and passenger frontal airbags, front and rear 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 and available around view monitors.
The BMW X5 xDrive45e weighs 767 to 1208 pounds more than the Lexus RXL. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The X5 xDrive45e’s corrosion warranty is 6 years longer than the RXL’s (12 vs. 6 years).
BMW pays for scheduled maintenance on the X5 xDrive45e for 2 years and 26000 miles longer than Lexus pays for maintenance for the RXL (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 X5 xDrive45e’s warranty.
The X5 xDrive45e’s 3.0 turbo 6-cylinder hybrid produces 99 more horsepower (389 vs. 290) and 180 lbs.-ft. more torque (443 vs. 263) than the RX 350L’s standard 3.5 DOHC V6. The X5 xDrive45e’s 3.0 turbo 6-cylinder hybrid produces 81 more horsepower (389 vs. 308) than the RX 450hL’s standard 3.5 DOHC V6 hybrid.
On the EPA test cycle the X5 xDrive45e running on electricity gets better fuel mileage than the RX 450hL (47 city/54 hwy MPGe vs. 29 city/28 hwy).
The X5 xDrive45e can drive on battery power alone for up to 16 miles. The RXL must run its internal combustion engine to move.
The X5 xDrive45e has a gallon more fuel capacity than the RXL Hybrid’s standard fuel tank (18.2 vs. 17.2 gallons), for longer range between fill-ups.
The X5 xDrive45e’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.
For better traction, the X5 xDrive45e has larger standard tires than the RXL (265/50R19 vs. 235/65R18). The X5 xDrive45e’s optional tires are larger than the largest tires available on the RXL (F:275/40R21 & R:315/35R21 vs. 235/65R18).
The X5 xDrive45e’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 RXL’s standard 65 series tires. The X5 xDrive45e’s optional 275/40R21 front and 315/35R21 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 X5 xDrive45e has standard 19-inch wheels. Smaller 18-inch wheels are standard on the RXL. The X5 xDrive45e’s optional 21-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 X5 xDrive45e 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.
The front and rear suspension of the X5 xDrive45e 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 X5 xDrive45e has a standard driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The RXL’s suspension doesn’t offer adjustable shock absorbers.
The X5 xDrive45e has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The X5 xDrive45e’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 X5 xDrive45e’s wheelbase is 7.3 inches longer than on the RXL (117.1 inches vs. 109.8 inches).
For better handling and stability, the track (width between the wheels) on the X5 xDrive45e is 1.7 inches wider in the front and 2.9 inches wider in the rear than on the RXL.
For greater off-road capability the X5 xDrive45e has a greater minimum ground clearance than the RXL (8.3 vs. 8.1 inches), allowing the X5 xDrive45e to travel over rougher terrain without being stopped or damaged.
The front grille of the X5 xDrive45e 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.
The X5 xDrive45e has 1 inch more front headroom, 1.7 inches more front shoulder room, .2 inches more rear headroom, 6.5 inches more rear legroom and .3 inches more rear shoulder room than the RXL.
For enhanced passenger comfort on long trips the X5 xDrive45e’s available third row seats recline. The RXL’s third row seats don’t recline.
The X5 xDrive45e has a much larger cargo volume with its rear seat folded than the RXL with all its rear seats folded (71.2 vs. 70.7 cubic feet).
A low lift-over cargo hatch design makes loading and unloading the X5 xDrive45e easier. The X5 xDrive45e’s cargo hatch lift-over height is 30.8 inches, while the RXL’s liftover is 31.9 inches.
The X5 xDrive45e’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.
The X5 xDrive45e’s standard towing capacity is much higher than the RXL’s (7200 vs. 0 pounds).
The engine in the X5 xDrive45e 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.
The X5 xDrive45e’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The RXL’s cruise control switches are unlit, making them difficult to find at night and operate safely.
The X5 xDrive45e offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the RXL.
To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW X5 xDrive45e offers an optional wireless phone charging system (Qi) in the center console. The RXL doesn’t offer wireless personal charging.
The X5 xDrive45e’s optional Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The RXL doesn’t offer an automated parking system.
