Audi: New sophisticated all-wheel drive quattro Ultra (video)
The Audi develops transmission that changed our everyday driving, but the map of the race, the quattro system, to improve the consumption of four-wheel drive models.
As you know, cars with permanent four-wheel drive consume more fuel than purely dikinita, due to increased friction transmission.
The new Ultra technology, this system normally operates at the front axle and sends torque to the rear and only when necessary.
Using a series of sensors that control the steering angle and the position of the accelerator, the processor, which is mounted on the gearbox, knows when the front wheels is losing traction and then transfers a proportion of the power back.
Also, in cooperation with the stability control system, sensors and can determine if the car is driven briskly and then engage if necessary the rear wheels.
The new all-wheel drive will make its official premiere of the new Audi A4 Allroad.
