Lightweighting also termed vehicle weight reduction or mass reduction – is an enormous challenge for today's auto makers. It is primarily focused on how to increase fuel economy and meet upcoming CAFE standards in the United States.
Reducing Vehicle Weight with 3M Automotive Technology
Reducing Weight in Cars: For Reduced Fuel Usage and Increased Range
One of the biggest challenges faced by the automotive industry today is vehicle lightweighting. Automotive manufacturers and suppliers face tough requirements when it comes to vehicle weight reduction and its impact on fuel economy and manufacturing costs, especially considering:
The 2025 Corporate Average Fuel Economy (CAFE) standard of 54.5 MPG for cars and trucks in the United States
The need for mass reduction in hybrid and electric vehicles to achieve maximum efficiency and range
The critical challenge of reducing weight while retaining or improving performance and affordability

Weight reduction is already a significant consideration in companies' product development efforts, and the emphasis is only going to increase in the years ahead. This is according to the Society of Automotive Engineers (SAE) members responding to a fall 2012 online survey conducted by 3M and SAE's Automotive Engineering International magazine by Signet Research. Find out which technology trends they believe will have the most impact in helping automakers meet fuel-economy targets.
Acrylic Foam Tapes Help Seal the Deal for Weight Savings
One area of focus for weight reduction in vehicles is the primary sealing system used around door and trunk openings. 3M took on the challenge and found a new way to attach the seal to the flange. The tape system eliminates weight in three ways: It removes metal from the extrusion, allows for the reduction of flange size around the body opening, and enables the use of lower gauge steel or aluminum body panels.
Challenged to find new ways to reduce parts weight without sacrificing mechanical or aesthetic properties, a global supplier of interior plastic trim components achieved weight reductions of 5 to 13 percent in key components by replacing conventional talc filler with glass bubbles in a proprietary polypropylene compound.
