THE Q5 is the first Audi SUV to use the lat­est it­er­a­tion of its qu­at­tro all-wheel drive set-up.

Dubbed “qu­at­tro ul­tra”, it lets the ve­hi­cle op­er­ate as a front-driver when cruis­ing. A pair of clutches (one in front of the prop shaft, an­other in the rear diff) dis­en­gages to im­prove fuel ef­fi­ciency.

If the driver ac­cel­er­ates, or the ESP senses trac­tion changes, the AWD re-en­gages and up to 100 per cent of torque can be sent to ei­ther axle.

Fuel sav­ings are en­hanced by a pre­dic­tive ef­fi­ciency as­sis­tant that uses the sat­nav data to en­cour­age the driver — via an icon in the vir­tual cock­pit — to ease off the throt­tle for ap­proach­ing speed lim­its, tight cor­ners or down­hill stretches. It op­er­ates both with the adap­tive cruise con­trol or when the driver is in charge.
