Compare the2023 BMW X4VS 2022 Porsche Cayenne Coupe

The X4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Cayenne Coupe doesn’t offer pre-crash pretensioners.

The X4 has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Cayenne Coupe doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The X4 offers optional Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Cayenne Coupe doesn’t offer backup collision prevention brakes.

The X4’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. A lane departure warning system costs extra on the Cayenne Coupe.

The X4 has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Cayenne Coupe’s blind spot costs extra.

To help make backing out of a parking space safer, the X4 has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the Cayenne Coupe.

The X4’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Cayenne Coupe doesn’t offer a driver alert monitor.

Both the X4 and the Cayenne Coupe 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, rearview cameras and available around view monitors.

BMW pays for scheduled maintenance on the X4 for 2 years and 26000 miles longer than Porsche pays for maintenance for the Cayenne Coupe (3/36,000 vs. 1/10,000).

There are over 80 percent more BMW dealers than there are Porsche dealers, which makes it much easier should you ever need service under the X4’s warranty.

J.D. Power and Associates rated the X4 third among compact premium SUVs in their 2022 Initial Quality Study. The Cayenne Coupe isn’t in the top three in its category.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Porsche vehicles. J.D. Power ranks BMW above average in initial quality. With 35 more problems per 100 vehicles, Porsche is rated below average.

On the EPA test cycle the X4 gets better mileage than the Cayenne Coupe running its gasoline engine:

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the BMW X4 higher (5 to 7 out of 10) than the Porsche Cayenne Coupe (3 to 5). This means the X4 produces up to 24.5 pounds less smog-producing pollutants than the Cayenne Coupe every 15,000 miles.

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The X4 has a standard Brake Assistant to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Cayenne Coupe doesn’t offer a brake assist feature.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X4 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Cayenne Coupe doesn’t offer run-flat tires.

The BMW X4 may be more efficient, handle and accelerate better because it weighs about 500 to 1250 pounds less than the Porsche Cayenne Coupe.

The X4 is 6.6 inches shorter than the Cayenne Coupe, making the X4 easier to handle, maneuver and park in tight spaces.

Pulling a handle automatically lowers the X4’s rear seats, to make changing between passengers and cargo easier. The Cayenne Coupe doesn’t offer automatic folding seats.

The X4 offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Cayenne Coupe doesn’t offer a remote starting system.

If the windows are left open on the X4 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote or with the driver’s door power window switch. The driver of the Cayenne Coupe can only operate the windows from inside the vehicle, with the ignition on.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the X4 has standard extendable sun visors. The Cayenne Coupe doesn’t offer extendable visors.

J.D. Power and Associates rated the X4 second among compact premium SUVs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Cayenne Coupe was rated third in its category.
