MONTVALE, N.J. - Mercedes-Benz new line of Bluetec vehicles will join Volkswagen’s Jetta TDI as clean-diesel vehicles that qualify for the IRS’ alternative-powertrain tax credit. It used to be that just hybrid vehicles qualified for the credit, but the advance of clean-diesel technology has allowed the two German automakers to secure the coveted tax break for their diesel lines, according to


The credits only count toward the first 60,000 units sold, and they vary depending on a vehicle’s fuel economy. For instance, the Benz ML320 Bluetec qualifies for a $900 rebate, but step up to the GL320 and you’re looking at a $1,800 credit. The Jetta TDI is on sale now, and the Bluetec line will hit showrooms in October.
