On Friday, the Environmental Protection Agency announced that it would order Volkswagen to recall nearly 500,000 vehicles in the United States because they were equipped with software that allowed them to evade emissions standards for reducing smog during testing. No recall has been ordered yet, however, until Volkswagen can outline how it intends to fix the problem.
But whatever the technological solution, it will most likely mean reducing the performance, drivability or fuel economy of cars to meet emission goals.
