Safety Comparison

The X6 M 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 doesn’t offer a whiplash protection system.

A passive infrared night vision system optional on the X6 M 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 Cayenne doesn’t offer a night vision system.

The X6 M has standard BMW Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Cayenne doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the X6 M and the Cayenne have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, all-wheel drive, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

The X6 M’s corrosion warranty is 2 years longer than the Cayenne’s (12 vs. 10 years).

BMW pays for scheduled maintenance on the X6 M for 4 years and 50,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Porsche doesn’t pay scheduled maintenance for the Cayenne.

There are over 74 percent more BMW dealers than there are Porsche dealers, which makes it much easier should you ever need service under the X6 M’s warranty.

Engine Comparison

The X6 M’s 4.4 turbo V8 produces 151 more horsepower (567 vs. 416) and 118 lbs.-ft. more torque (553 vs. 435) than the Cayenne S E-Hybrid’s standard 3.0 supercharged V6 hybrid. The X6 M’s 4.4 turbo V8 produces 147 more horsepower (567 vs. 420) and 147 lbs.-ft. more torque (553 vs. 406) than the Cayenne S’ standard 3.6 turbo V6. The X6 M’s 4.4 turbo V8 produces 47 more horsepower (567 vs. 520) than the Cayenne Turbo’s standard 4.8 turbo V8.

Tires and Wheels Comparison

For better traction, the X6 M has larger tires than the Cayenne (F:285/40R21 & R:325/30R21 vs. 255/55R18).

The X6 M’s 285/40R21 front and 325/30R21 rear tires provide better handling because they have a lower 40 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the Cayenne’s standard 55 series tires. The X6 M’s tires are lower profile than the Cayenne’s optional 35 series tires.

For better ride, handling and brake cooling the X6 M has standard 21-inch wheels. Smaller 18-inch wheels are standard on the Cayenne.

Suspension and Handling Comparison

The rear suspension of the X6 M uses air springs for a smoother, controlled ride than the Cayenne, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The X6 M has a standard automatic rear load leveling suspension to keep ride height level with a heavy load or when towing. The Cayenne doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the X6 M’s wheelbase is 1.5 inches longer than on the Cayenne (115.5 inches vs. 114 inches).

Passenger Space Comparison

The X6 M has .3 inches more front headroom, 3 inches more front shoulder room and 2.9 inches more rear shoulder room than the Cayenne.

Ergonomics Comparison

The X6 M’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the Cayenne.

The X6 M offers an optional heads-up display which projects speed and navigation instruction readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The Cayenne doesn’t offer a heads-up display.

To improve rear visibility by keeping the rear window clear, the X6 M has a standard rear variable intermittent wiper with a full on position. The rear wiper standard on the Cayenne only has an intermittent setting, so in a hard rain visibility isn’t as good.

When the X6 M is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Cayenne’s mirror doesn’t automatically adjust for backing.

Standard BMW Apps for the X6 M allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations, tagging songs to buy them later, following twitter accounts and other connected activities without taking their eyes off the road or their hands from the wheel. The Cayenne doesn’t offer factory integrated smartphone program access.

The X6 M’s optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Cayenne doesn’t offer an automated parking system.
