Chrysler is offering two-mode hybrid technology for the Chrysler Aspen and Dodge Durango next year, the company announced. The technology will be linked to the all-new 5.7-litre HEMI V8 motor combining fuel efficiency with performance in a Sports Utility Vehicle (SUV), according to Frank Klegon, executive vice president of product development in the Chrysler Group.
The new 5.7-litre HEMI Hybrid is expected to deliver an overall fuel economy improvement of more than 25 per cent, including an improvement of nearly 40 per cent in city driving conditions.
In addition to two electric motors, another feature of the system is the Multi-displacement System (MDS), which allows the engine to alternate between four-cylinder mode when less power is needed and V- 8 mode when more power is in demand.
Chrysler's two-mode hybrid has been jointly developed by DaimlerChrysler, General Motors and the BMW Group in a combination of electric motors with a fixed-gear transmission.
The new Chrysler Aspen Hybrid and Dodge Durango Hybrid vehicles can be powered either by the electric motors or by the 5.7-litre HEMI V-8 engine or a combination of the two modes.
The hybrid system can use the electric motors for boosting and/or regenerative braking. When full power is needed, the system automatically adjusts for passing, driving steep grades or hauling a trailer.
