Yep, that thing’s got a Hemi in it. The 5.7 Liter Hemi V-8 comes standard with Chrysler’s Multi-Displacement System (MDS) allowing the engine to operate on less cylinders when they aren’t needed for greater fuel economy. As a two-mode hybrid, the 2009 Dodge Durango Hybrid can run solely on electric power at lower speeds and also use electric assist while operating at higher speeds allowing the Durango Hybrid to benefit from its electric motors at low and high speeds. Speed control is managed through an Electric Continuously Variable Transmission (ECVT) which uses two electric motors to vary speed.
