I drive normally, 5 mph over speed limit and I'm getting 54 mpg in warmer weather. Only hypermiling technique I use is pushing EV button when speed is under 25 and running as much as I can on pure EV mode. I'll also do this at lights/stops signs as you can give it more power without the engine kicking on when in EV mode. I also use PWR a fair amount to get up to speed quickly and then glide vs. the long slow slog some recommend. That seems to work well for good mileage.
