Light-Duty Vehicle CAFE and GHG Standards
This 25-page report by the Alliance of Automobile Manufacturers says meeting America's 2025 fuel economy standards will be far more difficult that regulators thought when they set them in 2011.
This 25-page report by the Alliance of Automobile Manufacturers says that meeting America's 2025 fuel economy standards will be far more difficult that regulators thought when they set the goals in 2011.
The report, which was posted in June 2016, urges agencies that are currently conducting a midterm review of the standard to take a more holistic view about the likely fuel economy gains ahead. It says some assumptions made in 2012 are "beyond current technological realities."
The assessment figures nearly half of new cars sold in 2025 will need to deliver fuel economy akin to today's hybrids. AAM says achieving that goal is likely to require a significantly greater proportion of hybrid and electric powertrains than regulators assumed five years ago.
Revised safety standards, tighter fuel economy requirements, and cost pressures are forcing wholesale change to current light truck body-on-frame designs. The Auto/Steel Partnership’s Lightweight SUV Frame project has a strong contender for this frame of the future.
As OEMs and suppliers seek lightweight solutions to meet higher fuel economy standards through multi-material structures, conventional welding techniques are beginning to give way to new solid-state joining methods better suited for creating strong bonds between dissimilar metals.
Have economies of scale come to the production of automotive parts with carbon fiber materials?
