The Stelvio Quadrifoglio offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The SQ5 doesn’t offer ceramic brake rotors.

Motor Trend

Tires and Wheels

For better traction and acceleration, the Stelvio Quadrifoglio has larger rear tires than the SQ5 (285/40R20 vs. 255/45R20).

The Stelvio Quadrifoglio’s 285/40R20 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the SQ5’s standard 45 series tires.

Suspension and Handling

The Stelvio Quadrifoglio’s front to rear weight distribution is more even (52.9% to 47.1%) than the SQ5’s (54.3% to 45.7%). This gives the Stelvio Quadrifoglio more stable handling and braking.

The Stelvio Quadrifoglio handles at .95 G’s, while the SQ5 Prestige pulls only .93 G’s of cornering force in a Car and Driver skidpad test.

The Stelvio Quadrifoglio executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the SQ5 Prestige (24.6 seconds @ .79 average G’s vs. 25.7 seconds @ .73 average G’s).

Cargo Capacity

The Stelvio Quadrifoglio has a larger cargo volume with its rear seat folded than the SQ5 with its rear seat folded (56.5 vs. 53.1 cubic feet).

Ergonomics

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. The SQ5 doesn’t offer an easy entry system.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Stelvio Quadrifoglio has standard headlight washers to keep headlight output high. The SQ5 doesn’t offer headlight washers.

To help drivers see further while navigating curves, the Stelvio Quadrifoglio has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The SQ5 doesn’t offer cornering lights.

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 SQ5 doesn’t offer a house-current electrical outlet.
