CGI does sound pretty cool. You can obviously see the benefits to it but I'm typically never really worried about strength of the block as they've never really had issues. I'm more concerned about the internal components and what those will be made out of and if they're forged or not.

With at least 75% higher tensile strength, 45% higher stiffness and approximately
double the fatigue strength of convent
ional grey cast iron and aluminium, CGI allows engine designers to improve
performance, fuel economy and durability while reducing engine size, weight, noise and emissions.
