The principle is simple: in the same way that four brakes ensure better deceleration, four driven wheels enable better acceleration and higher cornering stability. Audi quattro four-wheel drive is the systematic application of this basic physical principle.
But that's not all: depending on the driving situation and road surface, quattro technology also distributes drive power continuously between the front and rear axles. Especially on slippery surfaces, this means better traction and safe progress, even in conditions in which vehicles with two driven wheels are no longer able to grip.
