Audi introduces fuel-efficient quattro all-wheel drive system
Audi has introduced a new quattro all-wheel drive system which features "ultra" technology. Set to debut on the Audi A4 Allroad, the new all-wheel drive system is designed to be more efficient that previous systems without sacrificing traction or driving dynamics. In order to accomplish this, the all-wheel drive system has been equipped with an assortment of sensors that continuously monitor road conditions, vehicle data, and driver behavior. When the system detects that all-wheel drive isn't necessary, the all-wheel drive system will automatically disconnect and the model will be powered exclusively by the front wheels.![2015 Chevrolet Corvette to get optional Performance Data Recorder [videos]](https://cdn.motor1.com/custom/share/motor1_loadimage_small.jpg)
