Later in 2008, Dodge will add the all-new 2009 Dodge Ram and the 2009 Dodge Durango HEMI Hybrid, a hybrid electric vehicle that combines fuel-efficient advanced hybrid technology with full-size SUV performance and capability. A Dodge Ram 1500 Hybrid will be available after 2009.
Combining Chrysler’s Multi-displacement System (MDS) and two-mode hybrid technology to greatly improve fuel economy, the 5.7-liter HEMI Hybrid V-8 will offer up to 40 percent fuel economy improvement in the city and 25 percent overall. The two-mode hybrid system is currently being introduced in the company’s 2009 Dodge Durango HEMI Hybrid and 2009 Chrysler Aspen HEMI Hybrid.
The two-mode hybrid system uses electric motors to allow the HEMI V-8 to remain in four-cylinder mode more often, improving fuel economy. In the first mode at low speeds and with light loads the vehicle may operate on electric power only, on engine power only, or any combination of the two. The Dodge Ram 1500 Hybrid may operate in electric-only mode during slow starts up to 25 mph. In addition, the HEMI V-8 can shut down when the vehicle comes to a stop. The second mode, used primarily at highway speeds, augments electric assist with full power from the 5.7-liter HEMI when conditions demand it.
The Dodge Ram 1500 Hybrid will also feature regenerative braking, which recycles electric energy that would normally be lost during braking or deceleration. This energy is reused to power the vehicle.
