In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The LX 570 has a standard brake assist system 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 doesn’t offer a brake assist feature.
For better traction, the LX 570 has larger standard tires than the Cayenne (275/50R21 vs. 255/55R19).

For better ride, handling and brake cooling the LX 570 has standard 20-inch wheels. Smaller 19-inch wheels are standard on the Cayenne.
The LX 570 has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the Cayenne, it requires you to depend on a temporary spare, which has mileage and speed limitations, or roadside assistance and a tow-truck.

The LX 570 has a higher standard payload capacity than the Cayenne (1280 vs. 1104 lbs.).
The LX 570 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.
The LX 570’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. An easy entry system costs extra on the Cayenne.
If the windows are left open on the LX 570 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or 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.
To improve rear visibility by keeping the rear window clear, the LX 570 has a standard rear fixed 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.
To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the LX 570 has standard extendable sun visors. The Cayenne doesn’t offer extendable visors.
