In the meantime, no one has to 'assume' any more. I've calculated the VE of this engine in these conditions.

Volumetric Efficiency calculator
Note that this calculator shows the Aveo's VE to be 79.999%
Givens: CFM=62.37, CID=97.64, RPM=2760
No. You are not using 62 cfm at cruise. Wrong. Measure your actual airflow.
