What is the stock psi the coolant cap can take on the older style vs the new style? Is the new cap rated at a higher psi? What are the psi differences between the different types?

Since I've got a 2011 with the nonpressurized system, I'm just spitballing. My guess was that they needed to increase the system pressure, but that became an issue with a nonpressurized overflow tank thus the pressurized tank. It's a (slightly) more complicated and expensive system, so I would assume they would need a solid reason to change it.
