And one wonders why Toyota engineers didn't do this themselves.

In other words, what are you breaking on your car by doing this.

Nothing so long as you monitor the ICE and inverter temperatures via a
Scangauge or similar.  When they start to get too hot you simply remove the
grille block.

Again, one wonders why Toyota engineers didn't do this themselves.  It's
quite easy--just do it with the appropriate thermostat, and keep the
coolant out of the radiator--out of the airstream--until it gets hotter.

So, the question stands:  what are you breaking by doing this.  What
DON'T you know about your car that the engineers DO know?  What
expensive tradeoffs are you making in order to play your rolling video
game and make a high score appear on the screen?

You're no doubt increasing the total cost of ownership of the car in
ways you haven't anticipated, because you're laser focused on one thing
and one thing only:  fuel mileage.  You think that gives you bragging
rights.

You're like the guy who throws nitro into his Civic, then blows it up
street running against another ricer.  You want one thing and one thing
only, and you don't care how much money you spend to get it.

It's highly ironic in this case that because you're doing things that
the engineers have already decided against, you're causing MORE harm to
the environment because your car won't last as long and will require
replacement sooner.

Your search for a high number on your rolling video game is harming the
environment.

It's not me, I drive a '97 Lumina 3.1 that gets half the MPG of the NHW20
Prius. I do want one with a burning passion though.  Requirements are NHW20
model, Seaside Pearl or Millennium Silver color, Smart key (SKS/SE,SS), non
Touring, and preferably '05-'07 model year.

And the Prius does have a thermostat on the ICE coolant loop but at 50 MPG
it is only burning about 1 gallon per hour and the block itself can
dissipate too much heat for it to stay warm.

Methinks they should have installed air shutters in front of the radiators
kind of like the old OTR trucks (semis / lorries)

I personally loathe those who forget that the primary purpose of the Prius
is low emissions not high MPG.  Some are hacking into the wiring for the
coolant temp sensor to fake a higher temp for better MPG. This is just
straight up wrong.  For me it falls right in line with the O2 simulators to
fake MPG gains from HHO or eliminate a P0420/P0430 when gutting or removing
the catalytic converter.

"Hypermiling" is a game.  Some people love to fool themselves playing games.
