How does the Q5's quattro AWD compare to Acura SH-AWD in real Canadian winter conditions?
The quattro ultra system in the 2018-and-newer Q5 is an on-demand AWD that decouples at highway speed for fuel savings and re-engages in milliseconds when slip is detected. Acura's SH-AWD actively distributes torque laterally across the rear axle — a step the entry-level quattro does not replicate. In real-world winter driving on snow-packed roads with proper winter tires, both systems perform excellently. Quattro brings 40 years of proven robustness; its only concession is slightly less fuel efficiency optimization versus quattro ultra on dry pavement. For a Canadian winter buyer, either system paired with winter tires delivers genuine confidence.
