Safety

The X6’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Murano doesn’t offer pre-crash pretensioners.

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

The X6’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Murano doesn’t offer a lane departure warning system.

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

The BMW X6 weighs 521 to 1312 pounds more than the Nissan Murano. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Warranty

The X6 comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Murano’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

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

BMW pays for scheduled maintenance on the X6 for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Nissan doesn’t pay scheduled maintenance for the Murano.

Reliability

To reliably power the ignition and other systems and to recharge the battery, the X6 has a standard 210-amp alternator. The Murano’s 150-amp alternator isn’t as powerful.

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

J.D. Power and Associates rated the X6 first among midsize premium SUVs in their 2018 Initial Quality Study. The Murano was rated third in its category.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Nissan vehicles. J.D. Power ranks BMW 8th in reliability, above the industry average. With 6 more problems per 100 vehicles, Nissan is ranked 10th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that BMW vehicles are more reliable than Nissan vehicles. Consumer Reports ranks BMW 6 places higher in reliability than Nissan.

Engine

The X6 s/xDrive35i’s standard 3.0 turbo 6 cyl. produces 42 more horsepower (302 vs. 260) and 55 lbs.-ft. more torque (295 vs. 240) than the Murano’s 3.5 DOHC V6. The X6 xDrive50i’s standard 4.4 turbo V8 produces 185 more horsepower (445 vs. 260) and 239 lbs.-ft. more torque (479 vs. 240) than the Murano’s 3.5 DOHC V6.

As tested in Motor Trend the X6 s/xDrive35i is faster than the Nissan Murano:

Fuel Economy and Range

Regenerative brakes improve the X6’s fuel efficiency by converting inertia back into energy instead of wasting it. The Murano doesn’t offer a regenerative braking system.

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 Murano doesn’t offer an automatic engine start/stop system.

The X6 has 3.4 gallons more fuel capacity than the Murano (22.4 vs. 19 gallons), for longer range between fill-ups.

Transmission

The X6’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 Murano doesn’t offer launch control.

Brakes and Stopping

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

Tires and Wheels

For better traction, the X6 has larger standard tires than the Murano (255/50R19 vs. 235/65R18). The X6’s optional tires are larger than the largest tires available on the Murano (F:275/40R20 & R:315/35R20 vs. 235/65R18).

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 Murano’s standard 65 series tires. The X6 xDrive50i’s optional 275/35R21 front and 315/30R21 rear tires have a lower 35 series front and 30 series rear profile than the Murano’s optional 55 series tires.

For better ride, handling and brake cooling the X6 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Murano. The X6 xDrive50i’s optional 21-inch wheels are larger than the 20-inch wheels optional on the Murano.

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 Murano doesn’t offer run-flat tires.

Suspension and Handling

The X6 has standard front and rear gas-charged shocks for better control over choppy roads. The Murano’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. Nissan doesn’t offer an active suspension on the Murano.

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 Murano’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 Murano doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the X6’s wheelbase is 4.3 inches longer than on the Murano (115.5 inches vs. 111.2 inches).

For better handling and stability, the track (width between the wheels) on the X6 is 2.6 inches wider in the rear than on the Murano.

The X6’s front to rear weight distribution is more even (50.2% to 49.8%) than the Murano’s (58.6% to 41.4%). This gives the X6 more stable handling and braking.

The X6 xDrive35i handles at .88 G’s, while the Murano Platinum AWD pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The X6 xDrive35i executes Motor Trend’s “Figure Eight” maneuver 1.7 seconds quicker than the Murano Platinum AWD (26.1 seconds @ .71 average G’s vs. 27.8 seconds @ .64 average G’s).

For greater off-road capability the X6 has a 1.4 inches greater minimum ground clearance than the Murano (8.3 vs. 6.9 inches), allowing the X6 to travel over rougher terrain without being stopped or damaged.

Cargo Capacity

To make loading groceries and cargo easier when your hands are full, the X6’s available liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Murano doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Towing

The X6’s standard towing capacity is much higher than the Murano’s (6000 vs. 1500 pounds).

Servicing Ease

The engine in the X6 is mounted longitudinally (North-South), instead of sideways, as in the Murano. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

The X6 has a maintenance free battery for long life without checking the battery’s water level. The Murano doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.

J.D. Power and Associates surveys of service recipients show that BMW service is better than Nissan. J.D. Power ranks BMW 8th in service department satisfaction (above the industry average). With a 33% lower rating, Nissan is ranked 20th.

Ergonomics

Unlike the driver-only memory system in the Murano SL/Platinum, 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 offers an optional heads-up display that 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 Murano doesn’t offer a heads-up display.

The power windows standard on both the X6 and the Murano 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 Murano 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 Murano’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 Murano S’ standard manually variable intermittent wipers have to be constantly adjusted. The Murano SV/SL/Platinum’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 Murano 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 Murano 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 Murano doesn’t offer automatic dimming high beams.

To help drivers avoid possible obstacles, the X6 has standard cornering lights to illuminate around corners when the turn signals are activated. The Murano doesn’t offer cornering lights. The X6 also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The X6’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Heated mirrors cost extra on the Murano and aren’t offered on the Murano S.

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 Murano offers an automatic rear view mirror, but its side mirrors don’t dim.

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 Murano doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the X6 owner. The Car Book by Jack Gillis rates the X6 with a number “1” insurance rate while the Murano is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the X6 is less expensive to operate than the Murano because typical repairs cost less on the X6 than the Murano, including $70 less for a timing belt/chain.
