Other cars don't necessary have a better design, they have different priorities. This car is designed to be lightweight, so they use less insulation and Little focus on placement and thermal isolation of the HVAC vents
I too noticed that this car blows a lot more heat than ambient outside air when the dials are all on cold and outside air. But only after its been sitting, after being run.
If you first start your car in the morning and turn the controls too cold and just vent, the cold air coming out of the vents will be blowing outside air very similar to ambient outside temperature. for as long as the car is moving. Get in traffic or turn the car off for a little while and it will blow hot air due to heat soak from the cowl and firewall.
So it appears that the system does close off the air properly and it is a heat soak issue because of the cars design and design priorities, not because it's necessarily a bad designed HVAC system.
As mentioned recirculate will stop the unwanted heat from coming in..
