Making vehicles lighter helps improve their fuel economy.
Making vehicles lighter helps improve their fuel economy. But "lightweighting" doesn't necessarily mean swapping materials, says David Mason, vice president Global Automotive at Altair.
The broader objective is to use less material without compromising performance and safety requirements. Mason points out that software tools such as those offered by Altair enable developers to quickly explore literally millions of design alternatives.
The forthcoming Chevy Colorado ZR2 is designed and engineered to be able to handle off-road situations of all types with aplomb.
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.
The common wisdom seems to be that midsize cars have pretty much had it in the U.S. new car market.
