In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the BMW X5 higher (6 out of 10) than the Porsche Cayenne (2 to 4). This means the X5 produces up to 27.7 pounds less smog-producing pollutants than the Cayenne every 15,000 miles.

The X5’s 255/50R21 front tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Cayenne’s standard 55 series front tires.

The design of the BMW X5 amounts to more than styling. The X5 has an aerodynamic coefficient of drag of .29 Cd. That is lower than the Cayenne (.3 to .35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the X5 get better fuel mileage.

The X5 has 1.7 inches more front headroom, .9 inches more front shoulder room, .4 inches more rear headroom and 1.6 inches more rear shoulder room than the Cayenne.

The X5 has a larger cargo volume with its rear seat folded than the Cayenne with its rear seat folded (67.7 vs. 60.3 cubic feet).

The X5 has a standard 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 doesn’t offer a remote starting system.

If the windows are left open on the X5 the driver can close all of them 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. The driver of the Cayenne can only operate the windows from inside the vehicle, with the ignition on.

The X5’s optional power side swing out doors make it much easier to load and unload kids and cargo. One touch opens the door, before you even get to the sport utility. The Cayenne doesn’t offer a power rear door.

The X5’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Cayenne’s cruise control switches are unlit, making them difficult to find at night and operate safely.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the X5 has standard extendable sun visors. The Cayenne doesn’t offer extendable visors.

Both the BMW X5 and the Porsche Cayenne have a standard Qi wireless phone charging system in the front seat.
