Compare the2024 Porsche Cayenne CoupeVS 2024 BMW X3 M

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 X3 M doesn’t offer height-adjustable seat belts.

Over 200 people are killed each year when backed over by motor vehicles. The Cayenne Coupe offers optional Maneuver Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The X3 M doesn’t offer backup collision prevention brakes.

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 X3 M doesn’t offer a night vision system.

Both the Cayenne Coupe and X3 M 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 X3 M’s Cross Traffic Warning doesn’t automatically brake.

Both the Cayenne Coupe and the X3 M have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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 available around view monitors.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Porsche vehicles are more reliable than BMW vehicles. Consumer Reports ranks Porsche 1 place higher in reliability than BMW.

The Cayenne Coupe has more powerful engines than the X3 M:

On the EPA test cycle the Cayenne Coupe running its gasoline engine gets better mileage than the X3 M:

The Cayenne Coupe S E-Hybrid/Turbo E-Hybrid’s standard fuel tank has 1.3 gallons more fuel capacity than the X3 M (18.5 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 X3 M (23.7 vs. 17.2 gallons).

For better stopping power the Cayenne Coupe CCB’s front brake rotors are larger than those on the X3 M:

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 X3 M 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 X3 M doesn’t offer air brakes.

For better traction, the Cayenne Coupe’s optional tires are larger than the largest tires available on the X3 M (F:285/45R21 & R:315/40R21 vs. F:255/45R20 & R:265/45R20).

The Cayenne Coupe’s optional 315/35R22 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the X3 M Competition’s 40 series tires.

For better ride, handling and brake cooling the Cayenne Coupe offers optional 22-inch wheels. The X3 M’s largest wheels are only 21-inches.

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 X3 M 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 X3 M.

The Cayenne Coupe has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The X3 M 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 X3 M (114 inches vs. 112.8 inches).

For better maneuverability, the Cayenne Turbo GT’s turning circle is 3.3 feet tighter than the X3 M’s (38 feet vs. 41.3 feet). The Cayenne Coupe’s turning circle is 1.3 feet tighter than the X3 M’s (40 feet vs. 41.3 feet).

For greater off-road capability the Cayenne E-Hybrid Coupe has a greater minimum ground clearance than the X3 M (8.2 vs. 8.1 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 1.4 inches higher than on the X3 M (9.5 vs. 8.1 inches).

The front grille of the Cayenne Coupe uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The X3 M doesn’t offer active grille shutters.

The Cayenne Coupe has .8 inches more front legroom, 1.5 inches more front shoulder room, 3.6 inches more rear legroom and .5 inches more rear shoulder room than the X3 M.

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 X3 M doesn’t offer electronic trailer sway control.

The Cayenne Coupe has a much higher maximum payload capacity than the X3 M (1501 vs. 840 lbs.).

J.D. Power and Associates surveys of service recipients show that Porsche service is better than BMW. J.D. Power ranks Porsche third in service department satisfaction. With a 13% lower rating, BMW is ranked 7th.

Unlike the driver-only memory system in the X3 M, 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 X3 M 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 X3 M does not have an oil pressure gauge.

Heated windshield washer nozzles are standard on the Cayenne Coupe to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The X3 M 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 Cayenne Coupe offers available headlight washers to keep headlight output high. The X3 M 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 X3 M doesn’t offer secondary sun visors.

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 X3 M.

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 X3 M.

The Cayenne Coupe’s optional Active Parking Assistance can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote ParkAssist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The X3 M’s automatic parking system does not offer parking by remote control.
