Hello everyone,
I'm a long time user here but I have been away for around 5 years now.
Ever since that time, the Prius was released in Brazil, and I've been eyeing one ever since its release, to replace my wife's Fit (which was previously mine). A few weeks ago I found a used one, model year 2013, with about 27k miles, in very good condition and at a good price relative to its supposed market value. As a result, my wife is now the proud owner of a Prius -- one of the few hundred, probably less than a thousand, that were sold in the country since 2012.
Thus I'm looking for a general strategy for hypermiling the Prius (when my wife lets me drive it, that is). So far I've read most of the pages in Hobbit's web site, and from there I gathered that a good strategy for low-speed driving is to pulse at the engine's sweet spot, which is around 1500 rpm/15 kW output (I'm using an ELM327 WiFi dongle plus EngineLink for the iPhone and iPad for instrumentation), and then glide using a light touch to the throttle pedal, trying to get close to zero on the HSI.
As for highway driving, I haven't had the opportunity to drive the Prius on the highway yet, but I understand I should try something similar, but replacing a glide by warp stealth, which is well described in Hobbit's web site. I've also read about the so-called super highway mode, but I'm not sure if I should try it.
I'd like to ask if I got the gist of it, and if anyone would like to point me toward other techniques that I should be aware of.
Also, I have a couple specific questions.
I've cycled through all the possibilities I've found on both displays (the black and white one with the HSI, and the color touchscreen with the energy monitor), but I haven't found a way to display the current trip's average MPG (since the car was started), or the instantaneous MPG -- I've noticed the bar chart near the speedometer, but I'd rather have a numerical display. When the car is powered down, some information is displayed on the black and white display, including the current trip's average MPG, so the car definitely keeps track of that information, but I haven't found a way to display it while I'm driving. It appears that both the current trip's average MPG and the instantaneous MPG used to be displayed on the touchscreen display of the 2nd gen Prius, but is it correct to say it's gone in the 3rd gen?
Also, when I say MPG above, I actually mean L/100 km, which is the default unit displayed on our Prius. I've grown used to MPG as a fuel consumption unit, and so I've searched for a way to change the unit from L/100 km to MPG. Having gone through the settings menu on the black and white display, I didn't find a setting that changes the fuel consumption unit. Has anyone found a way to change it?
Finally, what should I aim for with regards to the battery number of bars/SoC? At first I was trying to keep it close to the bottom, with the reasoning that I should leave as much headroom for charging the battery as possible. Obviously I understand that I shouldn't forcefully charge the battery, since the conversion efficiency from mechanical to electrical and back to mechanical energy is rather low, but the point is that if I suddenly need to brake, there should be headroom for charging the battery. On the other hand, it appears that this coaxes the car into more aggressively charging the battery, and given the issue of conversion efficiency, this strategy might be a net loss. I've read some people here try the opposite -- keeping the battery SoC as right as possible. So what should I aim for?
Thanks in advance to anyone who takes the time to clear up my doubts above.
