“The all-new Chrysler Group HEMI Hybrid will offer our customers the best of both worlds: renowned performance and significantly improved fuel economy,” said Frank Klegon, Executive Vice President – Product Devel opment, Chrysler Group. “With the new HEMI-powered Chrysler Aspen Hybrid, we are delivering the ultimate combination of fuel efficiency, overall performance and capability in a premium full-size SUV.”
The new 5.7-liter HEMI Hybrid is expected to deliver an overall fuel economy improvement of more than 25 percent, including an improvement of nearly 40 percent in the city.
The HEMI powerplant, in hybrid form, will continue to feature Chrysler Group’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. For the fifth year in a row — and every year since its 2003 re-introduction — Chrysler Group’s famous 5.7-liter HEMI engine has earned a place on Ward’s 10 Best Engines list.
The new Chrysler Aspen Hybrid and Dodge Durango Hybrid vehicles represent a bold change in what is generally a “me too” category. Chrysler Group’s full-size hybrid vehicles will deliver seamless dependable power on demand in an efficient package. With an electrically variable transmission (featuring two electric motors), two full hybrid modes of operation, and four fixed mechanical gear ratios, the drive system improves fuel economy around town and at highway speeds.
Boasting elegant Chrysler styling, unsurpassed capability and performance and abundant premium amenities, the Chrysler Aspen is a premium SUV that is a value alternative to luxury-priced competitors. Offering more for less, Aspen features numerous premium features, elegant Chrysler design, 30 safety features and best-in-class horsepower, torque and interior room.
Chrysler Group’s two-mode hybrid powertrain — jointly developed by DaimlerChrysler, General Motors and the BMW Group — represents a major automotive industry milestone due to the unprecedented fully integrated combination of electric motors with a fixed-gear transmission.
As a result of the low- and high-speed electric continuously variable transmission (ECVT) modes, the system is commonly referred to as the two-mode hybrid. However, the sophisticated fuel-saving system also incorporates four fixed gear ratios for high efficiency and power-handling capabilities in a broad variety of vehicle applications. The new Chrysler Aspen Hybrid and Dodge Durango Hybrid vehicles can be powered either by the electric motors or by the 5.7-liter HEMI V-8 engine – or a combination of the two. During the two ECVT modes and four fixed-gear operations, 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. The result is trend-setting hybrid technology that provides superior fuel economy, performance and load-carrying capability.
