Something special went down in Audi‘s history when a white A6 allroad 3.0 TDI rolled off the assembly line in Neckarsulm, Germany. It just so happens that car is the five millionth to be built with the brand’s quattro all-wheel drive technology. Right now, Audi can boast having built more than 140 quattro variants, its said in a press release.
“Quattro is one of the key pillars of our brand and has been a critical factor in our successful history,” said Audi chairman of the board of management Rupert Stadler.
Audi says over 43 percent of its customers chose to buy their car with quattro all-wheel drive in 2012. Particularly popular in North America, Russia, and the Middle East, the Q5 SUV was most frequently purchased with the system.
After its debut in 1980, quattro has since progressed to encompass several systems. In the A3, Q3, and TT, power is biased to the front wheels but is capable of diverting almost all the engine’s power to the rear.
On the other hand, most model put 60 percent of the engine’s torque to the rear wheels by default while torque is distributed between the wheels to maximize traction. Finally, the RS4 and RS5 use a version that can direct up 85 percent of the torque to the front wheels, or up to 70 percent to the rear.
