Big serious trucks are not usually what comes to mind when you think of the word "hybrid" but in a world of $100+ barrels of light sweet crude, Peterbilt is putting out some products that may change that. Its medium duty Model 330 (photo above) is just like a Prius. Except it takes diesel and boasts as much torque as a herd of Prii.
The tax credits that the federal government offers for buying hybrid vehicles are tied to sales. As the sales of any given model exceed 60,000 units total, the tax credit is phased out. The Toyota Prius is no longer eligible for federal tax credits, although some states still offer money back. Fortunately other manufacturers haven't yet sold as many hybrids as Toyota and are still eligible.
