Soon people shopping for a new, clean-burning diesel vehicle in the U.S. will be eligible for the same tax incentives that owners of hybrids have been receiving for years. The tax incentives are part of Dubbya's new national energy plan that will soon be signed into law. The incentives can amount up to $3,400 in tax credits based on the weight, fuel efficiency rating and emissions levels of a diesel-powered vehicle as rated by the EPA. The press release implies that Congress credits itself for the rising popularity of hybrids because of the tax incentives it enacted for those vehicles in 2001. Not that they're vain or anything, they're just saying. The legislative body hopes to create the same effect for diesels, which J.D. Power and Associates estimates will make up 7.5% of the market by 2012.
