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.
Every ten milliseconds, the system analyzes an assortment of data to determine if all-wheel drive is needed. The activation of the all-wheel drive system follows a three-stage strategy which includes proactive, predictive, and reactive functions. The first two stages activate the all-wheel drive system before it is needed, while the latter stage “rarely occurs in practice” but activates the four-wheel drive system when the car encounters a sudden loss of traction such as when the car hits an icy patch of road.
Audi says the new all-wheel drive system helps to reduce fuel consumption as tests have shown models equipped with the system consume about 0.3 liters/100 kilometers less fuel than conventional systems.
