The Cayenne Coupe has a standard Multi-collision Brake System, 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 Cayenne Coupe. But it costs extra on the Murano.
When descending a steep, off-road slope, the Cayenne Coupe’s standard Porsche Hill Control allows you to creep down safely. The Murano doesn’t offer Porsche Hill Control.
A passive infrared night vision system optional on the Cayenne Coupe 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 Cayenne Coupe and the Murano have standard driver and passenger frontal airbags, front and rear 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 lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.
The Porsche Cayenne Coupe weighs 534 to 1851 pounds more than the Nissan Murano. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The Cayenne Coupe 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 Cayenne Coupe’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 Porsche vehicles are more reliable than Nissan vehicles. J.D. Power ranks Porsche second in reliability, above the industry average. With 29 more problems per 100 vehicles, Nissan is ranked 15th.
From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Porsche vehicles are more reliable than Nissan vehicles. Consumer Reports ranks Porsche 3 places higher in reliability than Nissan.
The Cayenne Coupe’s standard 3.0 turbo V6 produces 75 more horsepower (335 vs. 260) and 92 lbs.-ft. more torque (332 vs. 240) than the Murano’s 3.5 DOHC V6. The Cayenne S Coupe’s standard 2.9 turbo V6 produces 174 more horsepower (434 vs. 260) and 166 lbs.-ft. more torque (406 vs. 240) than the Murano’s 3.5 DOHC V6. The Cayenne E-Hybrid Coupe’s standard 3.0 turbo V6 hybrid produces 195 more horsepower (455 vs. 260) and 276 lbs.-ft. more torque (516 vs. 240) than the Murano’s 3.5 DOHC V6. The Cayenne Turbo Coupe’s standard 4.0 turbo V8 produces 281 more horsepower (541 vs. 260) and 328 lbs.-ft. more torque (568 vs. 240) than the Murano’s 3.5 DOHC V6. The Cayenne Turbo S E-Hybrid Coupe’s standard 4.0 turbo V8 hybrid produces 410 more horsepower (670 vs. 260) and 423 lbs.-ft. more torque (663 vs. 240) than the Murano’s 3.5 DOHC V6.
The Cayenne Turbo S E-Hybrid Coupe can drive on battery power alone for up to 31 miles. The Murano must run its internal combustion engine to move.
Regenerative brakes improve the Cayenne Coupe’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 Cayenne Coupe’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 Cayenne Coupe’s standard fuel tank has 4.7 gallons more fuel capacity than the Murano (23.7 vs. 19 gallons).
The Cayenne Coupe’s optional 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 Cayenne Coupe’s brake rotors are larger than those on the Murano:
The Cayenne Coupe offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Murano doesn’t offer ceramic brake rotors.
The Cayenne Coupe Turbo has standard air brakes, which adjust the spoiler automatically during high-speed braking in order to shorten stopping distances. The Murano doesn’t offer air brakes.
For better traction, the Cayenne Coupe has larger standard tires than the Murano (F:275/45R20 & R:305/40R20 vs. 235/65R18). The Cayenne Coupe’s optional tires are larger than the largest tires available on the Murano (F:285/40R21 & R:315/35R21 vs. 235/65R18).
The Cayenne Coupe’s standard 275/45R20 front and 305/40R20 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the Murano’s standard 65 series tires. The Cayenne Coupe’s optional 285/35R22 front and 315/30R22 rear tires have a lower 35 series front and 30 series rear profile than the Murano SL/Platinum’s 55 series tires.
For better ride, handling and brake cooling the Cayenne Coupe has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Murano. The Cayenne Coupe’s optional 22-inch wheels are larger than the 20-inch wheels on the Murano SL/Platinum.
The Cayenne Coupe offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Murano doesn’t offer an active sway bar system.
The Cayenne Coupe 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 Cayenne Coupe 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 or off-road. The Murano’s suspension doesn’t offer adjustable shock absorbers.
The Cayenne Coupe has a standard automatic 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 Cayenne Coupe’s wheelbase is 2.8 inches longer than on the Murano (114 inches vs. 111.2 inches).
For better handling and stability, the average track (width between the wheels) on the Cayenne Coupe is 1.7 inches wider in the front and 1.6 inches wider in the rear than the track on the Murano.
The Cayenne Coupe’s front to rear weight distribution is more even (55.9% to 44.1%) than the Murano’s (58.9% to 41.1%). This gives the Cayenne Coupe more stable handling and braking.
For greater off-road capability the Cayenne Coupe has a 1.3 inches greater minimum ground clearance than the Murano (8.2 vs. 6.9 inches), allowing the Cayenne Coupe to travel over rougher terrain without being stopped or damaged. The Cayenne Coupe Air Suspension’s minimum ground clearance is 2.7 inches higher than on the Murano (9.6 vs. 6.9 inches).
The Cayenne Coupe’s standard towing capacity is much higher than the Murano’s (7700 vs. 1500 pounds).
The engine in the Cayenne Coupe 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 Porsche service is better than Nissan. J.D. Power ranks Porsche first in service department satisfaction. With a 61% lower rating, Nissan is ranked 17th.
Unlike the driver-only memory system in the Murano SL/Platinum, the Cayenne Coupe offers an optional driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle and climate settings and the front passenger seat also adjusts to the new passenger’s preset preferences.
The Cayenne Coupe’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Murano does not have an oil pressure gauge.
The Cayenne Coupe 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 Cayenne Coupe’s power parking brake sets with one touch and releases with one touch. The Murano
The power windows standard on both the Cayenne Coupe and the Murano have locks to prevent small children from operating them. When the lock on the Cayenne Coupe 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 Cayenne Coupe’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 Cayenne Coupe’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 Cayenne Coupe offers available headlight washers to keep headlight output high. The Murano doesn’t offer headlight washers.
To help drivers see further while navigating curves, the Cayenne Coupe offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Murano doesn’t offer cornering lights.
Manual rear side window sunshades are available in the Cayenne Coupe to help block heat and glare for the rear passengers. The Murano doesn’t offer rear side window sunshades.
The Cayenne Coupe’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 Cayenne Coupe offers optional 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.
