Alfa Romeo’s innovation and technology

Pure driving pleasure on every surface

Thanks to the innovative Q4 All-Wheel Drive system featured on Giulia and Stelvio, the driver is free to enjoy unique driving sensations and world class safety at all times. The Q4 system monitors grip conditions and driver’s inputs in real time to ensure the best performance by delivering always ideal torque distribution between the axles. This way the car adapts instantly to the road, providing top class comfort, perfect grip and handling beyond comparison. There’s no difference between snow, ice, rain, gravel or sand, the Q4 All-Wheel Drive system provides top driving sensation everywhere.

Best in class vehicle control

Alfa Romeo's Q4 AWD system allows the vehicle to travel as a pure RWD but can instantly deliver up to 50% of the engine torque to the front axle when tyre grip is approaching its traction limit. Torque distribution is constantly modulated with high precision according to the effective traction conditions and driver commands. The Q4 system stabilizes the vehicle instantly, allowing it to come out of a corner faster, thanks to the different transmission ratios between front and rear axles. This translates into best in class vehicle control in terms of traction and directional stability.

The art of mechanics

The entire Q4 system has been designed with challenging and innovative specifics: the Active Transfer Case (ATC) can adjust and modify the amount of torque sent to the front axle with top-of-the-class reaction times. The Q4 can also withstand an intensive use by dissipating the energy in the clutch assembly without adding external cooling systems. This guarantees reduced fuel consumption and great driving reliability in the long term as well. The Alfa Romeo Q4 is not just a normal AWD, but a technological breakthrough in terms of driving pleasure.

Giulia Q4

Giulia was created with a no-compromise approach. All of Giulia’s features, from its design to its mechanics, live in perfect harmony with each other. The Q4 All-Wheel Drive system completes a long list of technological solutions that raised once again the bar of driving excellence. Giulia Q4 is the triumph of a lifelong heritage devoted to driving pleasure.
