Audi reaffirms its commitment to all-wheel-drive in the electric-car era

German car maker Audi has reaffirmed its commitment to all-wheel-drive, even as it pivots with the rest of the car industry to electric power. As Audi celebrates the 40th anniversary of its all-wheel-drive “quattro” system, the company says it is well progressed with plans to evolve the technology and apply it to pure electric cars. Unlike mechanical all-wheel-drive systems – in which the front and rear drivelines are connected – electric cars power the front and rear wheels independently.
