We knew last month that the Jetta TDI was qualified for the tax credit. Now, word is out that all of the new-generation clean diesels for Volkswagen (TDI) and Mercedes-Benz (Bluetec) will be joining the elite handful of vehicles that qualify for a federal alternative-powertrain tax credit. Formerly reserved for just hybrid vehicles, the diesels have been designated as advanced lean-burn-technology vehicles that meet the Alternative Motor Vehicle Credit standards of the IRS. The credits vary based on the vehicle. In the case of Mercedes, the ML320 qualifies for $900 while the GL320 is good for $1,800. If diesel still isn't your thing, the IRS has also qualified several Ford hybrids as eligible too. Of those, the highest credit (a sweet $3,000) goes to those consumers who take home an Escape or Mariner two-wheel drive hybrid crossover.
