Safety Comparison

When descending a steep, off-road slope, the X6 xDrive’s standard Hill Descent Control allows you to creep down safely. The QX50 doesn’t offer Hill Descent Control.

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 QX50 doesn’t offer a night vision system.

The X6 has standard BMW Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The QX50 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the X6 and the QX50 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.

The BMW X6 weighs 610 to 1315 pounds more than the Infiniti QX50. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Warranty Comparison

The X6’s corrosion warranty is 5 years longer than the QX50’s (12 vs. 7 years).

BMW pays for scheduled maintenance on the X6 for 4 years and 50,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Infiniti doesn’t pay scheduled maintenance for the QX50.

There are over 2 times as many BMW dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the X6’s warranty.

Reliability Comparison

To reliably power the ignition and other systems and to recharge the battery, the X6 has a standard 210-amp alternator. The QX50’s 130-amp alternator isn’t as powerful.

The battery on the X6 is in the trunk, which protects it from hot underhood temperatures which can degrade battery life. By keeping the X6’s battery 20 to 30 degrees cooler, its life is increased by years. The QX50’s battery is in the hot engine compartment.

Engine Comparison

The X6 s/xDrive35i’s standard 3.0 turbo 6 cyl. produces 33 lbs.-ft. more torque (300 vs. 267) than the QX50’s 3.7 DOHC V6. The X6 xDrive50i’s standard 4.4 turbo V8 produces 120 more horsepower (445 vs. 325) and 213 lbs.-ft. more torque (480 vs. 267) than the QX50’s 3.7 DOHC V6.

Fuel Economy and Range Comparison

On the EPA test cycle the X6 gets better fuel mileage than the QX50:





18 city/25 hwy

17 city/24 hwy




18 city/24 hwy

17 city/24 hwy


In heavy traffic or at stoplights the X6’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 QX50 doesn’t offer an automatic engine start/stop system.

The X6 has 2.4 gallons more fuel capacity than the QX50 (22.4 vs. 20 gallons), for longer range between fill-ups.

Brakes and Stopping Comparison

For better stopping power the X6’s brake rotors are larger than those on the QX50:

Tires and Wheels Comparison

For better traction, the X6 has larger standard tires than the QX50 (255/50R19 vs. 225/55R18). The X6’s optional tires are larger than the largest tires available on the QX50 (F:275/40R20 & R:315/35R20 vs. 245/45R19).

The X6’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 QX50’s standard 55 series tires. The X6’s optional 275/40R20 front and 315/35R20 rear tires have a lower 40 series front and 35 series rear profile than the QX50’s optional 45 series tires.

For better ride, handling and brake cooling the X6 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the QX50. The X6’s optional 20-inch wheels are larger than the 19-inch wheels optional on the QX50.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard 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 QX50 doesn’t offer run-flat tires.

Suspension and Handling Comparison

The X6 has standard front and rear gas-charged shocks for better control over choppy roads. The QX50’s suspension doesn’t offer gas-charged shocks.

The X6 offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Infiniti doesn’t offer an active suspension on the QX50.

The X6 offers an optional 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 QX50’s suspension doesn’t offer adjustable shock absorbers.

The X6 offers an optional automatic rear load leveling suspension to keep ride height level with a heavy load or when towing. The QX50 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the X6’s wheelbase is 2.1 inches longer than on the QX50 (115.5 inches vs. 113.4 inches).

For better handling and stability, the track (width between the wheels) on the X6 is 4.3 inches wider in the front and 6.2 inches wider in the rear than on the QX50.

Passenger Space Comparison

The X6 has 5.1 inches more front shoulder room, 2.6 inches more rear legroom and 2 inches more rear shoulder room than the QX50.

Cargo Capacity Comparison

The X6 has a much larger cargo area with its rear seat up than the QX50 with its rear seat up (20.5 vs. 18.6 cubic feet). The X6 has a much larger cargo area with its rear seat folded than the QX50 with its rear seat folded (53.9 vs. 49.7 cubic feet).

To make loading and unloading groceries and cargo easier, especially for short adults or children, the X6 has a standard power cargo door, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The QX50 doesn’t offer a power cargo door.

Ergonomics Comparison

Unlike the driver-only memory system optional at extra cost in the QX50, the X6 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 X6’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the QX50.

The X6 offers an optional heads-up display which projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The QX50 doesn’t offer a heads-up display.

The power windows standard on both the X6 and the QX50 have locks to prevent small children from operating them. When the lock on the X6 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX50 prevents the driver from operating the other windows just as it does the other passengers.

The X6’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The QX50’s rear power window switches have to be held the entire time to open or close them fully.

The X6’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 QX50’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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 QX50 doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The X6 offers available headlight washers to keep headlight output high. The QX50 doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the X6 detect other vehicles which could be blinded and automatically switch to low beams. The QX50 doesn’t offer automatic dimming high beams.

The X6 has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The QX50 offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the X6 and the QX50 have standard heated front seats. The X6 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the QX50.

Optional air conditioned seats in the X6 keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The QX50 doesn’t offer air conditioned seats.

On extremely cold Winter days, the X6’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The QX50 doesn’t offer a heated steering wheel.

Standard BMW Apps for the X6 allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations, tagging songs to buy them later, following twitter accounts and other connected activities without taking their eyes off the road or their hands from the wheel. The QX50 doesn’t offer factory integrated smartphone program access.

The X6’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 QX50 doesn’t offer an automated parking system.
