Prius wake turbulence

Drove for miles today on the freeway in the rain, behind and beside a Prius so I could study its wake turbulence made visible by the spray and mist.

Prius has noticeably less wake turbulence than other vehicles, especially coming out of the front wheel wells. Why is this? What geometry does Prius have to suppress or avoid the turbulence blowing out and interfering with the slipstream?

And, the boat-like fairings behind the rear wheels seem to suppress wake turbulence, but are probably not the last word.

So, can any Prius owner here post pics and text which address or explain this issue? Maybe we can copycat.
