Dodge introduces its line of hybrids with its Durango Hybrid. Working to retain their Hemi V8 engine, Dodge Hybrids drive their already practical fuel economy another 20 to 25 percent ahead of their conventional, fuel-driven counterparts. By using E85, by shutting off engine cylinders when unnecessary, and by cruising with two-mode hybrid technology, Dodge Hybrids should prove fiercely friendly to buyers looking for alternatively powered autos.
