Light-weight materials such as carbon-fiber, aluminum and magnesium are widely touted as key components of the drive towards greater fuel economy. Which explains why the automotive steel supplier industry is suddenly calling for an end to tailpipe emissions testing and a switch to the more holistic life cycle analysis testing. According to a press release from WorldAutoSteel, an industry group, the production of steel alternatives can create up to 20 times the carbon emissions of steel.
A day after Mazda had announced that the company “has become the first automaker to successfully develop vehicle components using 1,800 MPa ultra-high tensile steel,” Nissan announced “the world’s first Ultra High Tensile Strength Steel rated at 1.2 gigapascals (GPa).” So who’s on first?
5 minutes of in-depth research revealed that 1,800 MPa equal 1.8 GPa. In the heavy metal business, those Gs are similar to gigahertz or gigabytes in computers: The more, the merrier. Whether Mazda has outdone Nissan or v.v. is also a bit like Pentium and Athlon: It depends. What matters is that cars get both stronger and lighter
