The Alfa Romeo Stelvio benefits from Q4 All-Wheel Drive system; the innovative on-demand system that combines the advantages of four-wheel drive with the driving dynamics that only rear-wheel drive can deliver. The Q4 (All-Wheel Drive) system includes an active transfer case and front differential designed to meet the specific technical requirements of Alfa Romeo and responsively handle high torque levels with a particularly compact, lightweight set-up. It works by constantly monitoring road conditions and driving style, and optimising torque distribution between the front and rear axles, to maximise grip and handling on every road surface.
In normal weather conditions, the Alfa Romeo Stelvio acts like a rear-drive vehicle, with the Q4 system sending 100% of the torque to the rear axle, but if the system detects rear-wheel slippage it transfers up to 50% of the torque to the front axle in real time. The result is impeccable performance everywhere: on a hairpin bend, an unsurfaced track, a snow-covered straight or when cornering in driving rain.
