AUDI is getting set to launch the very latest version of its big-selling A4 allroad model which now comes fitted with an innovative new system that automatically switches from two to four-wheel drive.

It is designed for Audi models with longitudinally-installed engines and Audi says it will deliver benefits in terms of both fuel efficiency and carbon emissions output during every journey.

The new system deactivates the quattro all-wheel drive when it is not needed, but ensures that it is also permanently and instantaneously available, reducing the potential fuel consumption difference between the two drive configurations.

The newly developed quattro system will be available to order in the UK initially in conjunction with the 252bhp version of the 2.0-litre TFSI engine powering the latest A4 allroad. Three other TDI engine variants in the A4 allroad range will also open for order at the end of April, with first deliveries scheduled to begin in June.

The all-wheel drive system’s intelligent control works predictively, always looking ahead by means of a comprehensive array of sensors and the continuous analysis of the driving dynamics, road condition and driver behaviour. Consequently, the quattro system is always ready when needed.

No prices have yet been revealed, but true to Audi tradition, all A4 allroad models will come very well equipped.
