I just turned in my two best tanks ever: 47.3mpg and 47.7mpg; both tanks were over 700mi. My previous best was 42.9mi.

The two techniques I tried were turning off the A/C and discovering that I could sometimes convince the car to run ICE-only at very high FE above about 40mph.

I think I stumbled onto something that I've seen described elsewhere as super-highway mode (SHM) on the Prius. From what I've read, it's characterized by a dramatic increase in FE when the engine goes to IGN 14. I don't have a ScanGauge, so I can't confirm the IGN setting or characterize this on the TCH, but I suspect this is what is happening.

The way I get into this mode is to accelerate to highway speed, then let up ever so slightly on the accelerator to maintain the same speed. If FE doesn't significantly increase, I let up a little bit more while maintaining speed. Eventually, I'll see a significant jump (~10mpg or more), which usually places the FCD needle above 50mpg, usually pegged on 60mpg.

Has anyone else looked into SHM on the Camry Hybrid?

Thanks,
Chris

Hi Chris:

___It exists in the TCH as well!

I have noticed that if I hold 55 to 65 mph on relatively flat or slightly inclined road I can hold between 50 and 60 mpg on the real time display. I think quite a bit has to do with the amount of incline you have.

The LOD values have to stay light. Also SHM isn't enabled in the Camry till you hit S4 (at least on my tests).
