What does the Q4 on an Alfa Romeo mean?

The Alfa Romeo Q4 system is the standard all-wheel-drive system that comes with the Stelvio or Giulia. The system is named after Quadrifoglio, which means four-leaf clover in Italian, the iconic symbol of the Alfa Romeo brand.

How does Alfa Romeo Q4 work?

Essentially, the Alfa Romeo Q4 system is the brain of the vehicle's engine that powers, alerts, and adjusts both the Alfa Romeo Stelvio Q4 and Alfa Romeo Giulia Q4 driving systems.

The system continuously monitors various internal and external parameters simultaneously in both the front and rear axles, and adjusts the engine power available between the two axles according to road conditions to ensure a safe and smooth drive.

The Alfa Romeo Q4 system does all the thinking

Alfa Romeo always goes to great lengths to keep weight down, and the engineers have managed to do so. The Alfa Romeo Q4 system's included active transfer case and front axle add only 56kg to the vehicle weight over a RWD version offered in other markets. These components are designed to kick in when needed, the moment they are needed.

Under normal driving circumstances, 100% of the power is fed to the rear differential for maximum efficiency. However, the instant driving conditions change, or the driver modifies their behavior, the system will send up to 60% of available power to the front axle.

Regardless of the road conditions, the Alfa Romeo Q4 system keeps the driver in complete control by constantly monitoring grip conditions and driving inputs in real-time. If necessary, the system transfers up to half of the engine's torque to the front wheels through a lightweight and compact differential. The result is a powerful, smooth, sporty, and enjoyable driving experience every time with your Giulia Q4 or Stelvio Q4.

The Alfa Romeo's control box

Included with Alfa Romeo vehicles are the Chassis Domain Controller (CDC) and driver-adjustable Alfa DNA or DNA Pro (exclusive to Quadrifoglio vehicles) drive mode system. They are responsible for modifying the Q4's comportment based on driver input and selected drive mode.

The CDC, or the "brain", coordinates all of the vehicle's various active driving systems including traction and stability control, the torque vectoring differential and available Alfa Active suspension system. Through a set of programmed constraints, the system will promptly react in a predictable and balanced manner. The CDC works in conjunction with the Alfa DNA drive mode selector that, through the various drive modes, enables set dynamic system programs for optimal and predictive driving.

So if you are looking for a powerful, all-wheel drive SUV with traction control in West Island, Dollard-des-Ormeaux (DDO) or Montreal, then come to your local Alfa Romeo dealer, Des Sources Alfa Romeo in DDO. Take advantage of Alfa Romeo financing options and lease specials.
