In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The Stelvio Quadrifoglio has a standard Panic 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 and acceleration, the Stelvio Quadrifoglio has larger rear tires than the Cayenne (285/40R20 vs. 275/50R19).

The Stelvio Quadrifoglio’s 255/45R20 front and 285/40R20 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the Cayenne’s standard 55 series front and 50 series rear tires.

For better ride, handling and brake cooling the Stelvio Quadrifoglio has standard 20-inch wheels. Smaller 19-inch wheels are standard on the Cayenne.

The Alfa Romeo Stelvio Quadrifoglio may be more efficient, handle and accelerate better because it weighs about 250 to 1350 pounds less than the Porsche Cayenne.

The Stelvio Quadrifoglio is 8.6 inches shorter than the Cayenne, making the Stelvio Quadrifoglio easier to handle, maneuver and park in tight spaces.

The design of the Alfa Romeo Stelvio Quadrifoglio amounts to more than styling. The Stelvio Quadrifoglio has an aerodynamic coefficient of drag of .34 Cd. That is lower than the Cayenne (.34 to .35). A more efficient exterior helps keep the interior quieter and helps the Stelvio Quadrifoglio get better fuel mileage.

The Stelvio Quadrifoglio 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 Stelvio Quadrifoglio’s standard easy entry system 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.

The Stelvio Quadrifoglio’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.

Heated windshield washer nozzles are standard on the Stelvio Quadrifoglio to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Cayenne doesn’t offer heated windshield washer nozzles.

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

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Alfa Romeo Stelvio Quadrifoglio offers an optional wireless phone charging system (Qi) in the center console. The Cayenne doesn’t offer wireless personal charging.

The Stelvio Quadrifoglio offers an optional 115-volt a/c outlet in the cargo area, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Cayenne doesn’t offer a house-current electrical outlet.
