|WASHINGTON - When DaimlerChrysler unveiled the Dodge ESX3
concept car in Washington, D.C., today, Delphi Automotive Systems proudly shared in the
celebration, having supplied the vehicle's hybrid electric propulsion system.
Automotive Systems is proud to be a supplier to DaimlerChrysler Corporation on the Dodge
ESX3, a concept vehicle that combines lower fuel consumption, reduced emissions and cost
efficiencies with high customer appeal in the next-generation family car," said
Charles L. Rose, Delphi customer director for DaimlerChrysler.
The ESX3 builds on the knowledge and experience gained from the Dodge Intrepid ESX in
1996 and the ESX2 in 1998. It also draws on technology developed through the
government-industry collaboration known as the Partnership for a New Generation of
According to Chief Engineer Gary Cameron, Delphi, working as a supplier to
DaimlerChrysler and the U.S. Department of Energy, developed the Energen(TM) Hybrid
Electric Propulsion System components for the DaimlerChrysler 3rd-Generation PNGV concept
car. The Energen(TM) Hybrid Electric Propulsion System is a high-efficiency, high-energy
density, air-cooled, embedded permanent-magnet motor with a highly integrated power
In addition, Delphi developed the battery safety system in conjunction with other
program partners as well as a new high-power connection system. The progress in fuel
efficiency and costs stems from several major improvements in technology: The ESX3's mild
hybrid electric powertrain combines a clean, efficient diesel engine, electric motor and
state-of-the-art lithium-ion battery to achieve an average 72-mile-per-gallon (3.3
liters/100km) fuel efficiency (gasoline equivalent). That is 2 mpg better than the fuel
efficiency of the ESX2 in 1998 and close to PNGV's goal of up to 80 mpg (2.9 liters/100
The ESX3's powertrain, consisting of a three-cylinder, 1.5-liter, all-aluminum
direct-injected diesel engine and 15-kilowatt peak-power electric motor, advances
development of the powertrain in the ESX2.
As in the ESX2, the Dodge ESX3 hybrid powertrain reduces fuel energy use by relying on
the electric motor and battery to capture braking energy and reuse it to power accessories
and provide a boost during hard acceleration.
For additional fuel savings, the engine automatically shuts off when the vehicle is
stopped, and the air-cooled electric motor, which weighs just 76 pounds, instantly
restarts the engine when the accelerator pedal is pressed. "This program represents
the culmination of three years of research and development in partnership with the
Department of Energy, DaimlerChrysler and other suppliers," said Cameron, who leads
Delphi's Energenix team in Kokomo, Ind. We are very proud to be with DaimlerChrysler today
as it debuts its advanced technology vehicles. We believe these technologies represent the
future of automotive transportation systems and we are committed to working with industry
and government to enable these technologies to enter the market.
