    Height adjustable passenger seat. The Iltis utilized an early form of 4WD, which would later become synonymous with "quattro". The Haldex Traction LSC unit is not a differential and therefore cannot perform in the true sense like a differential. But Audi's AWD system doesn't just make the Q7 a strong performer in the snow--it can improve and optimize acceleration and handling all year long, rain or shine, on pavement, dirt, gravel, sand, and more. I have loved owning and driving this car, it has been the best car I have owned, so sad sale but it doesnt get enough use as I have my works van.

    The new quattro system uses an electro-mechanically operated multi-plate clutch and rear gear set that combine to eliminate mechanical drag by completely cutting drive to the rear differential, and with it the rear wheels, when the driver only requires front-wheel drive. In its place is a fully networked set-up capable of analysing the driving conditions every milliseconds and automatically providing either front- or four-wheel drive depending on factors such as longitudinal acceleration, engine torque, steering angle, yaw rate, prevailing traction and driving style.

    Our Verdict Audi R8 Audi sends its mid-engined flagship in search of supercar scalps, and largely succeeds - even if rivals like the Porsche Turbo S provide greater driving thrills. Unlike the old mechanical Torsen-based quattro system, which based its operation principally around existing traction levels, the new electro-mechanical system is influenced by a much wider range of information obtained by various sensors, as well as data relating to the road provided by the navigation system.

    By combining this information, Audi says its new quattro ultra system can provide predictive operation by constantly sensing whether the driver requires front- or four-wheel drive and adapting the apportioning of drive to suit.

    Depending on the model, it consists of between five and seven pairs of clutch plates that rotate in an oil bath. When the plates are pressed together, four-wheel drive is activated. The contact pressure between each plate is used to distribute drive between the front and rear axles. The front multi plate clutch works in combination with a newly developed dog gear style rear differential featuring a decoupler operated via a so-called claw clutch.

    When the decoupler is closed, the propshaft and differential are operated to provide drive to the rear wheels and thus provide four-wheel drive.

    When running in front-wheel drive, the front multi-plate clutch disconnects the propshaft. At the same time, a decoupling device within the rear differential opens to reduce friction and associated drag losses. Unlike the process used by the existing Torsen torque sensing quattro system, the only rear-wheel drive components engaged when running in front wheel drive are the bevel gears within the axle and gears within the differential — the latter of which compensate for differences in the speed of rotation of the wheels during cornering.

    The resulting reduction in mechanical drag along with revisions to the existing S-tronic dual clutch gear box are said to provide prototype versions of the A4 2. To activate four-wheel drive, the multi-plate clutch closes to operate the propshaft.

    In doing so, it accelerates the gears in the rear differential. When they are running at a necessary speed, the claw clutch closes via pretensioned springs to provide drive to the rear wheels, at point which an electromagnetically actuated pin disengages a locking lever.

    All up, the quattro ultra system is claimed to weigh four kilograms less than the existing Torsen based quattro system. If you drive a torsen Quattro in the snow it will be very sure footed under acceleration but with haldex the back end keeps stepping out as it dumps loads of power to the back in an unsubtle fashion when the front loses traction.
