Delphi's Dave Wohleen says a new coating cuts the weight of wires.
Delphi says its Packard Electric division will equip a vehicle to be introduced next year with thin-walled wires that weigh 25 percent less than traditional wiring.
The weight savings comes from a new type of flexible plastic coating that Delphi developed with General Electric's Advanced Materials division. GE will supply Delphi with resins for the product, called Flexible Noryl.
Delphi officials would not identify the first vehicle scheduled to use the new wiring.
Automakers are looking for ways to save weight in order to boost fuel efficiency and reduce emissions. Cars have been gaining weight and complexity in recent years as consumers have been demanding more electrical items, such as navigation systems.
The typical vehicle has about 18 kilograms of wiring, says Dave Wohleen, president of Delphi's Electronics & Mobile Communication sector. The new wire coating cuts that to about just under 14 kilograms.
GE and Delphi said the wiring is more expensive than conventional wiring but wouldn't give details.
