I keep trying to figure out why the es 350 has a drag of 0.29 vs the f sport and hybrid at 0.26? Doesn't make much sense to me at all.

 

The f sport and hybrid have the rear spoiler.

 

Spoilers add drag

 

The F Sport rides a little lower I think, they have different front fascias, different grill shapes.

A rear spoiler doesn't always add drag, they can also smooth out airflow out the back and reduce drag. For instance, in the 6ES all the Hybrids have spoilers.

 

The 300h has the same drag coefficient as the f sport.

 

Then its got to be the spoiler, only two things they have in common

 

It's crazy if that spoiler takes the drag from 0.29 to 0.26 drag coefficient. There aren't any closable front grille vents like the Prius right?

 

No, not that I'm aware of

 

Has to be the spoiler, as crazy as that is!

 

I wonder how much a front air dam, splitter, side skirt, and rear diffuser would lower the es drag even more? Toyota Japan has a full body kit and exhaust system that fits both the es 350 and hybrid.
