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.
