For enhanced safety, the front seat shoulder belts of the Porsche Cayenne Coupe are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X4 doesn’t offer height-adjustable seat belts.

Both the Cayenne Coupe and X4 have child safety locks to prevent children from opening the rear doors. The Cayenne Coupe 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 X4’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.

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 X4 doesn’t offer a night vision system.

Both the Cayenne Coupe and X4 have rear cross-traffic warning, but the Cayenne Coupe has Rear Cross Traffic Alert (automatically applies the brakes) to better prevent a collision when backing near traffic. The X4’s Cross Traffic Warning doesn’t automatically brake.

Both the Cayenne Coupe and the X4 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, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.

Reliability

Engine

The Cayenne Coupe has more powerful engines than the X4:

	Horsepower	Torque
Cayenne Coupe 3.0 turbo V6	348 HP	368 lbs.-ft.
Cayenne E-Hybrid Coupe 3.0 turbo V6 hybrid	463 HP	479 lbs.-ft.
Cayenne S Coupe 4.0 turbo V8	468 HP	442 lbs.-ft.
Cayenne GTS Coupe 4.0 turbo V8	493 HP	486 lbs.-ft.
Cayenne S E-Hybrid Coupe 3.0 turbo V6 hybrid	512 HP	553 lbs.-ft.
Cayenne Turbo GT 4.0 turbo V8	650 HP	626 lbs.-ft.
Cayenne Turbo E-Hybrid Coupe 4.0 turbo V8 hybrid	729 HP	700 lbs.-ft.
X4 xDrive30i 2.0 turbo 4-cylinder	248 HP	258 lbs.-ft.
X4 M40i 3.0 turbo 6-cylinder hybrid	382 HP	369 lbs.-ft.

Fuel Economy and Range

The Cayenne Coupe E-Hybrid’s standard fuel tank has 1.2 gallons more fuel capacity than the X4 (18.4 vs. 17.2 gallons), for longer range between fill-ups. The Cayenne Coupe’s standard fuel tank has 6.5 gallons more fuel capacity than the X4 (23.7 vs. 17.2 gallons).

Brakes and Stopping

For better stopping power the Cayenne Coupe’s brake rotors are larger than those on the X4:

	Cayenne Coupe	Cayenne Coupe CCB	X4 xDrive30i	X4 M40i
Front Rotors	14.2 inches	17.3 inches	13 inches	13.7 inches
Rear Rotors	13 inches	16.1 inches	13 inches	13.6 inches

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 X4 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 X4 doesn’t offer air brakes.

Tires and Wheels

For better traction, the Cayenne Coupe has larger standard tires than the X4 (F:255/55R20 & R:295/45R20 vs. 245/50R19). The Cayenne Coupe’s optional tires are larger than the largest tires available on the X4 (F:285/45R21 & R:315/40R21 vs. F:245/45R20 & R:275/40R20).

The Cayenne Coupe’s standard 295/45R20 rear tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the X4’s standard 50 series tires.

For better ride, handling and brake cooling the Cayenne Coupe has standard 20-inch wheels. Smaller 19-inch wheels are standard on the X4. The Cayenne Coupe’s optional 22-inch wheels are larger than the 21-inch wheels optional on the X4.

Suspension and Handling

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 X4 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. BMW doesn’t offer an active suspension on the X4.

The Cayenne Coupe has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The X4 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Cayenne Coupe’s wheelbase is 1.2 inches longer than on the X4 (114 inches vs. 112.8 inches).

For better maneuverability, the Cayenne Turbo GT’s turning circle is 1.7 feet tighter than the X4’s (38 feet vs. 39.7 feet).

For greater off-road capability the Cayenne E-Hybrid Coupe has a greater minimum ground clearance than the X4 (8.2 vs. 8 inches), allowing the Cayenne Coupe to travel over rougher terrain without being stopped or damaged. The Cayenne Turbo E-Hybrid Coupe’s minimum ground clearance is 1.5 inches higher than on the X4 (9.5 vs. 8 inches).

Passenger Space

The Cayenne Coupe has .4 inches more front legroom, 1.6 inches more front shoulder room, 1.1 inches more rear headroom, 4.5 inches more rear legroom and .5 inches more rear shoulder room than the X4.

Cargo Capacity

The Cayenne Coupe has a much larger cargo volume with its rear seat up than the X4 with its rear seat up (20.9 vs. 18.5 cubic feet). The Cayenne Coupe has a much larger cargo volume with its rear seat folded than the X4 with its rear seat folded (53 vs. 50.5 cubic feet).

Payload and Towing

Standard trailer sway control on the Cayenne Coupe uses the Porsche Stability Management sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The X4 doesn’t offer electronic trailer sway control.

The Cayenne Coupe has a much higher maximum payload capacity than the X4 (1501 vs. 1010 lbs.).

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Porsche service is better than BMW. J.D. Power ranks Porsche second in service department satisfaction. With a 32% lower rating, BMW is ranked 13th.

Ergonomics

Unlike the driver-only memory system in the X4, the Cayenne Coupe offers an optional 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 standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The X4 doesn’t offer an easy entry system.

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 X4 does not have an oil pressure gauge.

The Cayenne Coupe’s standard Comfort Access allow you to unlock the doors from any outside door handle, open the cargo door, and start the vehicle, all without removing the key from the pocket or purse. Comfort Go standard on the X4 only offers hands-free access for the ignition, none to unlock the vehicle.

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 X4 doesn’t offer headlight washers.

To better shield the driver and front passenger’s vision, the Cayenne Coupe has standard dual-element sun visors that can block glare from two directions simultaneously. The X4 doesn’t offer secondary sun visors.

Manual rear side window sunshades are available in the Cayenne Coupe to help block heat and glare for the rear passengers. The X4 doesn’t offer rear side window sunshades.

The Cayenne Coupe has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the X4.

The Cayenne Coupe offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the X4.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Porsche Cayenne has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the X4.

The Cayenne Coupe’s Active Parking Assistance can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Optional Remote ParkAssist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The X4’s automatic parking system does not offer parking by remote control.
