The four electric motors meant that Audi could design a virtual Quattro all-wheel-drive system, integrating the power distribution program with vehicle dynamics sensors. By default, the rear motors deliver 70 percent of the torque, the high number compensating for the 58 percent weight distribution to the rear wheels. But as conditions dictate, the power software can give any wheel greater or less power, which should make for incredible road-holding, beyond even Audi's current Quattro system.
The car's navigation and communication electronics are designed to communicate with external roads infrastructure, receiving information about traffic and green lights, for example, and adjusting routes accordingly to maximize driving efficiency.
As the amount and types of moving "informational parts" in the car increase, the value of the control function within the device will increase accordingly.
