Safety

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 LX 570 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.

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 LX 570 doesn’t offer a driver alert monitor.

For better protection of the passenger compartment, the X7 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 LX 570 uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the X7 and the LX 570 have standard driver and passenger frontal airbags, side-impact head airbags, front 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 available around view monitors.

Warranty

The X7’s corrosion warranty is 6 years longer than the LX 570’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 LX 570.

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.

Reliability

The battery on the X7 is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the X7’s battery 20 to 30 degrees cooler, its life is increased by years. The LX 570’s battery is in the hot engine compartment.

Engine

The X7 xDrive50i’s standard 4.4 turbo V8 produces 73 more horsepower (456 vs. 383) and 76 lbs.-ft. more torque (479 vs. 403) than the LX 570’s 5.7 DOHC V8.

Fuel Economy and Range

On the EPA test cycle the X7 gets better fuel mileage than the LX 570:

Regenerative brakes improve the X7’s fuel efficiency by converting inertia back into energy instead of wasting it. The LX 570 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the X7’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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The LX 570 doesn’t offer an automatic engine start/stop system.

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 LX 570 doesn’t offer launch control.

Brakes and Stopping

For better stopping power the X7’s brake rotors are larger than those on the LX 570:

Tires and Wheels

For better traction and acceleration, the X7 has larger standard rear tires than the LX 570 (315/35R22 vs. 275/50R21).

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 LX 570’s standard 50 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 LX 570’s 50 series tires.

For better ride, handling and brake cooling the X7 has standard 21-inch wheels. Smaller 20-inch wheels are standard on the LX 570. The X7’s optional 22-inch wheels are larger than the 21-inch wheels optional on the LX 570.

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 LX 570 doesn’t offer run-flat tires.

Suspension and Handling

For superior ride and handling, the BMW X7 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 LX 570 has a solid rear axle, with a non-independent rear suspension.

The front and rear suspension of the X7 uses air springs for a smoother, controlled ride than the LX 570, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

For a smoother ride and more stable handling, the X7’s wheelbase is 10 inches longer than on the LX 570 (122.2 inches vs. 112.2 inches).

For better handling and stability, the track (width between the wheels) on the X7 is 1.4 inches wider in the front and 2.3 inches wider in the rear than the average track on the LX 570.

Chassis

The BMW X7 may be more efficient, handle and accelerate better because it weighs about 400 to 450 pounds less than the Lexus LX 570.

Unibody construction lowers the X7’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 LX 570 uses body-on-frame design instead.

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 LX 570 doesn’t offer active grille shutters.

Passenger Space

The rear step up height for the X7 is 3.5 inches lower than the LX 570 (20.5” vs. 24”).

Cargo Capacity

The X7’s cargo area provides more volume than the LX 570.

Pressing a switch automatically lowers or raises the X7’s second and third row seats, to make changing between cargo and passengers easier. The LX 570 doesn’t offer automatic folding second row seats.

Towing

The X7’s standard towing capacity is much higher than the LX 570’s (7500 vs. 7000 pounds).

Ergonomics

Unlike the driver-only memory system in the LX 570, 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 power windows standard on both the X7 and the LX 570 have locks to prevent small children from operating them. When the lock on the X7 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The LX 570 prevents the driver from operating the other windows just as it does the other passengers.

The X7’s power mirror controls are mounted on the armrest for easy access. The LX 570’s power mirror controls are on the dash where they are possibly hidden by the steering wheel and are awkward to manipulate.

The X7 has standard heated front and optional heated second and third row seats, which keep the driver and passengers extremely comfortable in the winter. The LX 570 doesn’t offer a third-row heated seat.
