Aluminum Could Be 'Golden' In Quest for 54.5 MPG
Automakers' need to spend $157 billion to double the fuel economy of their fleets might mean years of rising sales for makers of turbochargers, aluminum body panels and other components that boost efficiency.
While producing more hybrid and electric cars will help, most progress toward reaching the required fleet average of 54.5 miles a gallon by 2025 will involve making internal-combustion-engine vehicles lighter and more efficient, said Zoe Lipman, senior manager for transportation solutions at the National Wildlife Federation Climate and Energy Program.
Those changes will include greater use of turbochargers to provide more power to smaller engines, and technology that shuts off engines when cars idle. They'll mean more use of aluminum and high-strength steel in body panels, engine blocks, transmissions and wheels.
