For enhanced safety, the front and rear seat shoulder belts of the Audi A6 Allroad have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Nissan Murano doesn’t offer pretensioners for the rear seat belts.
The A6 Allroad’s 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.
Both the A6 Allroad and Murano have child safety locks to prevent children from opening the rear doors. The A6 Allroad has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Murano’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The A6 Allroad has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Murano 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 A6 Allroad. But it costs extra on the Murano.
When descending a steep, off-road slope, the A6 Allroad’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 A6 Allroad Prestige 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.
Both the A6 Allroad and the Murano have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available blind spot warning systems and rear cross-path warning.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the A6 Allroad its highest rating: “Top Pick Plus” for 2020, a rating granted to only 32 vehicles tested by the IIHS. The Murano has not been fully tested, yet.
The A6 Allroad comes with a full 4-year/50,000-mile basic warranty, which covers the entire car 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 A6 Allroad’s corrosion warranty is 7 years longer than the Murano’s (12 vs. 5 years).
J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than Nissan vehicles. J.D. Power ranks Audi 8th in reliability, above the industry average. With 13 more problems per 100 vehicles, Nissan is ranked 15th.
The A6 Allroad’s 3.0 turbo V6 hybrid produces 75 more horsepower (335 vs. 260) and 129 lbs.-ft. more torque (369 vs. 240) than the Murano’s 3.5 DOHC V6.
Regenerative brakes improve the A6 Allroad’s fuel efficiency by converting inertia back into energy instead of wasting it. The Murano doesn’t offer a regenerative braking system.
The A6 Allroad’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.
For better stopping power the A6 Allroad’s brake rotors are larger than those on the Murano:
For better traction, the A6 Allroad has larger tires than the Murano (245/45R20 vs. 235/65R18).
The A6 Allroad’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Murano’s standard 65 series tires. The A6 Allroad’s tires are lower profile than the Murano SL/Platinum’s 55 series tires.
For better ride, handling and brake cooling the A6 Allroad has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Murano.
The A6 Allroad 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. The Murano’s suspension doesn’t offer adjustable shock absorbers.
For a smoother ride and more stable handling, the A6 Allroad’s wheelbase is 4 inches longer than on the Murano (115.2 inches vs. 111.2 inches).
For better maneuverability, the A6 Allroad Prestige w/All-Wheel Steering’s turning circle is 2.3 feet tighter than the Murano’s (36.4 feet vs. 38.7 feet).
For greater off-road capability the A6 Allroad Prestige has a greater minimum ground clearance than the Murano (7.3 vs. 6.9 inches), allowing the A6 Allroad to travel over rougher terrain without being stopped or damaged.
The A6 Allroad is 8.9 inches shorter in height than the Murano, making the A6 Allroad much easier to wash and garage and drive (lower center of gravity).
The design of the Audi A6 Allroad amounts to more than styling. The A6 Allroad has an aerodynamic coefficient of drag of .29 Cd. That is lower than the Murano (.31) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the A6 Allroad get better fuel mileage.
A low lift-over trunk design makes loading and unloading the A6 Allroad easier. The A6 Allroad’s trunk lift-over height is 27 inches, while the Murano’s liftover is 30.7 inches.
The engine in the A6 Allroad 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.
J.D. Power and Associates surveys of service recipients show that Audi service is better than Nissan. J.D. Power ranks Audi 8th in service department satisfaction (above the industry average). With a 25% lower rating, Nissan is ranked 17th.
The A6 Allroad Prestige has a standard 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 A6 Allroad’s power parking brake sets with one touch and releases with one touch or automatically. The Murano’s parking brake has to released manually.
The power windows standard on both the A6 Allroad and the Murano have locks to prevent small children from operating them. When the lock on the A6 Allroad 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 A6 Allroad’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 A6 Allroad’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.
In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A6 Allroad has standard headlight washers to keep headlight output high. The Murano doesn’t offer headlight washers.
Manual rear side window sunshades are available in the A6 Allroad to help block heat and glare for the rear passengers. The Murano doesn’t offer rear side window sunshades.
The A6 Allroad’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Nissan only offers heated mirrors on the Murano SV/SL/Platinum.
The A6 Allroad’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to 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 A6 Allroad has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel is only available on the Murano SL/Platinum.
The A6 Allroad Prestige offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Murano.
To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi A6 Allroad has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Murano.
The A6 Allroad’s optional Park Steering Assist 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.
