"Econ" guage on new HiHy

Previous posts mentioned the Econ button that you can push that will help the 2008 HiHy stay in it's most fuel efficient state as well as the EV button being standard. But, THIS ARTICLE mentions that there is also an "Econ" guage with white LED lights that tells you when you're driving in the most efficient band combining information, presumably, from fuel flow, rpm, amperage and battery SOC.

This is something that those of us with CAN-View have figured out with our Prius and even Scan-Guage to estimate (though without the benefit of battery info). I think this is a nice compromise that makes it easy for the non-technically inclined folks to figure out how to drive for best FE without overwhelming them with information they're not sure how to assimilate. I'm quite sure we'll see similar stuff on the next gen Prius too.
