Audi's Latest 'quattro' All-Wheel-Drive to be Used on New A4 allroad

Audi has been busy developing a new quattro all-wheel-drive system with the aim of reducing CO2 emissions and improving fuel efficiency.

The latest-generation A4 allroad quattro will be driven in front-wheel-drive mode while pottering around town, but with a refresh rate of every 10 milliseconds, the system can decide to send power to all wheels in a split second.

The self-locking centre differential generally sends 60% of the power to the rear wheels, with the other 40% being channeled through the front wheels. It can, however, send a maximum of 70% to the front, or 85% to the rear, should the conditions require it.

The quattro system decides what's necessary not only by monitoring the road conditions but also assessing the driving dynamics and behaviour.

As well as featuring the new quattro system, the new Audi A4 allroad quattro will have a 34 mm higher ground clearance over the standard Avant.

Engines include a 249 bhp 2.0-litre TFSI turbocharged petrol and three turbodiesels. A 2.0-litre TDI with 187 bhp and two 3.0-litre TDIs with 215 or 268 bhp.

Audi's class-leading technology can be specified, as expected, on the allroad. Not only does this include the Audi Virtual Cockpit and Matrix LED headlights, but an adaptive cruise control with traffic jam assist. A feature that can take care of not only throttle and braking, but also steering, in stop-start traffic at speeds of up to 37 mph.

Order books for the new Audi A4 allroad quattro are expected to open in late April, with first deliveries coming this June.
