The smoke path shown in the photo confuses me to no end.
Just as it gets to the bumper, it veers sharply to the right, directly behind
the front tire air deflector -- the black inverted eyebrow shape. ( I take it
that the Coanda effect is at work here once the air stream contacts the back
of the deflector.0
OK. So what in the heck is the air deflector doing? I would have guessed
that it was intended to delfect air to both the outside and inside of the tire.
Apparently not for this configuration of deflector.
Somewhere, probably here on EM, I have read that the front tire deflector's
size and distance from the tire is hyper critical. The deflector looks grossly
oversized to me, it as least twice the size of the one on my Prius, and
considerably farther forward, away from the tire.
Is it possible that this picture was originally intended only to show the
negative effect of an improperly sized/placed deflector?
Also, I see no evidence of rollers under the wheels. I take it then that the
wheels are not turning. Wouldn't that further minimize a widespread
applicability of the pictured air flow?
