To read hybrid and HEMI together in a headline is strange, but Chrysler makes it possible announcing the Dodge Ram HEMI Hybrid at the Detroit Auto Show 2008.
Dodge Ram HEMI Hybrid drain joins the Chrysler Aspen and Dodge Durango in the Chrysler hybrid vehicle lineup. The HEMI Hybrid is supposed to be available in 2010.
The HEMI powerplant, in hybrid form, will continue to feature Chrysler’s Multi-displacement System (MDS), which allows the engine to seamlessly alternate between four-cylinder mode when less power is needed and V-8 mode when more power is in demand. The two-mode hybrid system provides assistance from electric motors allowing the HEMI V-8 to remain in four-cylinder mode more often than without a hybrid powertrain, improving overall fuel economy.
Chrysler’s advanced, state-of-the-art two-mode full hybrid system — developed in partnership with General Motors, Mercedes-Benz and The BMW Group — integrates proven automatic-transmission technology with a patented hybrid-electric drive system to deliver the world’s first two-mode full hybrid.
As a result of low- and high-speed electrically variable transmission (EVT) modes, the system is defined as a “two-mode hybrid.” In addition, the sophisticated fuel-saving system incorporates four fixed-gear ratios for high efficiency and power-handling capabilities. During the two EVT modes, the system can use the electric motors to improve fuel economy, acceleration, and for regenerative braking to utilize energy that would normally be lost during braking or deceleration. The energy is stored in the batteries for later use.
The system’s two modes are optimized for city and highway driving.
In the first mode — at low speed and with light loads — the vehicle can operate in three ways:

- Electric power only
- Engine power only
The second mode is used primarily at highway speeds. In addition to electric assist, the second mode provides full power from the 5.7-liter HEMI® V-8 when conditions demand it, such as when passing, pulling a trailer or climbing a steep grade.
