Chrysler unveiled three different electric drive concept cars at the North American International Auto Show in Detroit: the Chrysler ecoVoyager Concept, an electric vehicle with a fuel cell range extender; the Jeep Renegade Concept, an electric vehicle with a BLUETEC diesel range extender; and the Dodge ZEO Concept, a battery electric vehicle with a 250-mile range.
Chrysler envisions its electric-drive systems to be modular, with a high-level of technology sharing and component reuse. Common elements include a 200 kW (268 hp) electric motor, electrical architecture, power electronics, and grid-chargeable lithium-ion battery technology, among others.

In execution, this approach is comparable to the efforts GM is making with its E-Flex system: common electric powertrain elements with varied sources of electricity.
Chrysler ecoVoyager Concept. The ecoVoyager is an electric vehicle with a 16 kWh lithium-ion battery module that supports a 40-mile all-battery range. Total driving range is 300 miles when coupled with the 45 kW PEM fuel cell range extender.
The common 200 kW electric motor drives the front wheels. Compressed hydrogen is stored in 700 bar (10,000 psi) tanks.

The Jeep Renegade. The Renegade concept also uses also an electric vehicle with the common 40-mile, 16 kWh lithium-ion battery module, but uses dual 200 kW motors—one on each axle—for four-wheel-drive capability.
Driving range is extended by an electric generator coupled to a 1.5-liter, 3-cylinder BLUETEC diesel engine. Renegade has a 400-mile combined range, and is capable of achieving an equivalent petroleum fuel economy of 110 mpg.
|Dodge ZEO BEV.|
The Dodge ZEO. The ZEO is a full Battery Electric Vehicle powered by the common electric motor driving the rear wheels. Driving range is 250 miles with the integrating of multiple lithium-ion battery modules for a total energy rating of 64 kWh.
According to Chrysler, addressing future challenges such as global warming, energy security and customer wants and needs will require the production implementation of one or more of these technologies in the not-too-distant future.
Chrysler highlighted the concepts as examples of the type of products that its new ENVI in-house organization is tasked to deliver. Chrysler formed ENVI late last year with a focus on establishing Chrysler leadership in electric-drive vehicles and related advanced-propulsion technologies. (Earlier post.)
ENVI is to focus on executing Chrysler’s next-generation vehicles with technologies that complement the company’s current hybrid vehicle plans, and extend the benefits of hybrid electric vehicles (HEV) and plug-in hybrid electric vehicles (PHEV).
