2008 Chrysler Aspen Hybrid
Chrysler has announced that it will introduce an additional gas-electric model in 2008: the Aspen Hybrid, a companion to the previously announced '08 Dodge Durango Hybrid.
Both vehicles have been developed in cooperation with General Motors and BMW at the companies' Hybrid Development Center in Troy, Michigan. The partners are jointly developing a two-mode hybrid system that can be adapted by each to its individual models. In the case of GM, the dual-mode hybrid system is being introduced initially on the Chevrolet Tahoe.
Chrysler's version of the two-mode system uses the company's 5.7-liter Hemi V8 and multi-displacement system, which shuts down half the cylinders under part throttle to save fuel. In addition, the dual-mode hybrid can run on the gasoline engine, the electric motor or both. It also features low- and high-speed continuously variable transmission modes (thus the "dual mode" appellation), as well as four fixed gear ratios.
Chrysler says the Hemi Hybrid system is capable of delivering a fuel-economy improvement of 25 percent, including up to 40 percent better mileage in city driving.
