Driving America Forward Act This bill expands the tax credit for new plug-in electric drive motor vehicles and extends the tax credit for new fuel cell motor vehicles. (Under current law, taxpayers who purchase a qualified plug-in electric drive motor vehicle are eligible for a tax credit of up to $7,500, which begins to phase out once a manufacturer sells 200,000 qualified vehicles.) The bill allows an additional 400,000 vehicles per manufacturer to be eligible for a credit of up to $7,000 before the credit begins to phase out. The bill also extends the tax credit for fuel cell motor vehicles through 2028. (Under current law, the credit expired after 2017.)
