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
