Chrysler will launch a hybrid version of the Chrysler Aspen next year at the same time as the Dodge Durango hybrid.

Both vehicles will powered by Chrysler Group's powered by Chrysler Group's all-new 5.7-liter Hemi hybrid powertrain. They will be the first volume-production hybrid offerings from the Chrysler Group and the first vehicles to feature DaimlerChrysler's two-mode hybrid technology.

DaimlerChrysler has developed the hybrid technology with GM and BMW. "We have found a way to integrate the electric motor technology and the transmission in such a way that it not only simply provides electric power to help move the vehicle when the gasoline in engine is not operating, but it allows us to keep the engine at an optimum state in many different driving conditions," explained Mark Chernoby, vice president of Advance Vehicle Engineering in a video posted on the YouTube website.

Chrysler claims the hybrid Hemi combination achieves a 25% improvement in fuel economy and almost 40% in the city over the standard 5.7 litre Hemi powered versions.

The Hemi powerplant, in hybrid form, will continue to feature Chrysler Group's 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.

Located in Troy, Mich., the DaimlerChrysler, GM and BMW Hybrid Development Center jointly developed the overall modular two-mode hybrid system and the individual components: electric motors, transmission, high-voltage battery, high-performance electronics, wiring, safety systems, energy management and hybrid system control units. In addition, the Hybrid Development Center is responsible for system integration and project management.
