The advanced design also makes it ultralight, quiet an fuel efficient with extremely compact dimensions. The CGI block is lighter and quieter than conventional gray cast iron and demonstrates at least 85 percent higher tensile strength, 45 percent higher stiff nee and approximately double the fatigue strength of iron and aluminum.
