All automotive wind tunnels use the same ISO calibration model and strive for the best accuracy,and they're publishing crosswind averaged Cds,with yaw up to around 8-degrees,but there remains a tunnel-to-tunnel discrepancy.Some tunnels are very close in their results.Hucho addresses this in his book.
We know from DARKO that the Cd 0.25 Prius scores Cd 0.285.
The 2016 might show Cd 0.273 if measured there.Don't know.
We do know that the Prius has come down from 0.29,to 0.24 over it's evolution,by Toyota metrics.By 2025 we should see very low Cds,snuck in each 4-year styling cycle in between.
