Safety Comparison

A passive infrared night vision system optional on the X5 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 GX460 doesn’t offer a night vision system.

The X5’s optional 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 GX460 doesn’t offer a driver alert monitor.

For better protection of the passenger compartment, the X5 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 GX460 uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the X5 and the GX460 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, daytime running lights, front parking sensors, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.

Warranty Comparison

The X5’s corrosion warranty is 6 years longer than the GX460’s (12 vs. 6 years).

BMW pays for scheduled maintenance on the X5 for 4 years and 50,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Lexus doesn’t pay scheduled maintenance for the GX460.

There are over 77 percent more BMW dealers than there are Lexus dealers, which makes it much easier should you ever need service under the X5’s warranty.

Reliability Comparison

The camshafts in the X5’s engine are driven by a hardened steel chain, with no maintenance needs. The GX460’s camshafts are driven by a rubber belt that needs periodic replacement. If the GX460’s cam drive belt breaks the engine could be severely damaged when the pistons hit the opened valves.

To reliably power the ignition and other systems and to recharge the battery, the X5 has a standard 210-amp alternator. The GX460’s 130-amp alternator isn’t as powerful.

The battery on the X5 is in the trunk, which protects it from hot underhood temperatures which can degrade battery life. By keeping the X5’s battery 20 to 30 degrees cooler, its life is increased by years. The GX460’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2015 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Lexus vehicles. J.D. Power ranks BMW 6th in initial quality, above the industry average. With 5 more problems per 100 vehicles, Lexus is ranked 9th.

Engine Comparison

The X5 xDrive50i’s standard 4.4 turbo V8 produces 144 more horsepower (445 vs. 301) and 151 lbs.-ft. more torque (480 vs. 329) than the GX460’s 4.6 DOHC V8.

The X5’s 3.0 turbo diesel produces 84 lbs.-ft. more torque (413 vs. 329) than the GX460’s 4.6 DOHC V8.

Fuel Economy and Range Comparison

On the EPA test cycle the X5 xDrive35d gets better fuel mileage than the GX460 (24 city/31 hwy vs. 15 city/20 hwy).

On the EPA test cycle the X5 s/xDrive35i xDrive gets better fuel mileage than the GX460 (18 city/24 hwy vs. 15 city/20 hwy).

Regenerative brakes improve the X5’s fuel efficiency by converting inertia back into energy instead of wasting it. The GX460 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the X5’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 GX460 doesn’t offer an automatic engine start/stop system.

Consumer Reports

Tires and Wheels Comparison

For better traction, the X5’s optional tires are larger than the largest tires available on the GX460 (F:275/40R20 & R:315/35R20 vs. 265/60R18).

The X5’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 GX460’s standard 60 series tires. The X5’s optional 275/40R20 front and 315/35R20 rear tires have a lower 40 series front and 35 series rear profile than the GX460’s 60 series tires.

For better ride, handling and brake cooling the X5 has standard 19-inch wheels. Only 18-inch wheels are available on the GX460. The X5 offers optional 20-inch wheels.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the X5 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The GX460 doesn’t offer run-flat tires.

Suspension and Handling Comparison

For superior ride and handling, the BMW X5 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 GX460 has a solid rear axle, with a non-independent rear suspension.

The X5 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 GX460.

For a smoother ride and more stable handling, the X5’s wheelbase is 5.7 inches longer than on the GX460 (115.5 inches vs. 109.8 inches).

For better handling and stability, the track (width between the wheels) on the X5 is 2.3 inches wider in the front and 2.6 inches wider in the rear than on the GX460.

The X5 xDrive35d xDrive handles at .82 G’s, while the GX460 pulls only .73 G’s of cornering force in a Motor Trend skidpad test.

The X5 xDrive50i xDrive executes Motor Trend’s “Figure Eight” maneuver 2 seconds quicker than the GX460 (26.3 seconds @ .72 average G’s vs. 28.3 seconds @ .58 average G’s).

For greater off-road capability the X5 has a greater minimum ground clearance than the GX460 (8.2 vs. 8.1 inches), allowing the X5 to travel over rougher terrain without being stopped or damaged.

Chassis Comparison

The BMW X5 may be more efficient, handle and accelerate better because it weighs about 50 to 450 pounds less than the Lexus GX460.

Unibody construction makes the X5’s chassis much stiffer, which contributes to better handling, and enables softer springs to be used for a better ride. Unibody construction’s stiffness also contributes to better durability and less body squeaks and rattles. The GX460 doesn’t use unibody construction, but a body-on-frame design.

The design of the BMW X5 amounts to more than styling. The X5 has an aerodynamic coefficient of drag of .33 Cd. That is lower than the GX460 (.35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the X5 get better fuel mileage.

Passenger Space Comparison

The X5 has 2.5 inches more front headroom, 6.1 inches more front shoulder room, 2.5 inches more rear legroom and 2.7 inches more rear shoulder room than the GX460.

Cargo Capacity Comparison

To make loading and unloading groceries and cargo easier, especially for short adults or children, the X5 has a standard power cargo door, which opens and closes automatically by pressing a button. The GX460 doesn’t offer a power cargo door.

Ergonomics Comparison

The X5 offers an optional heads-up display which projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The GX460 doesn’t offer a heads-up display.

If the windows are left down on the X5 the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the GX460 can only raise the windows from inside the vehicle, with the ignition on.

The X5’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The GX460’s standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the X5 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The GX460 doesn’t offer heated windshield washer nozzles.

The X5’s power mirror controls are mounted on the armrest for easy access. The GX460’s power mirror controls are on the dash, hidden behind the steering wheel, where they are awkward to manipulate.

The X5’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 GX460 doesn’t offer an automated parking system.
