New 2012 Prius first 600 miles, what Mode do you use, Normal, ECO or Power

Choose the mode that suits you, they are there to make you comfortable.
The highways I drive on have signs telling me the maximum speed I should drive. I would follow them within 10% if it was me.

Now for the first 600 miles, be gentle. No sudden full throttle, no steady RPMs. (unless you live on a floodplain, you won't have steady RPMs anyway)

 

I use normal & power......all depends on the mood I'm in.

As for the speed.......depends on what u want ur MPGs to look like

 

Use what suits your driving style. I run mostly freeways and come from a performance car backround. I run in PWR mode all the time and probably am between 55=90 mph most of the time I average 46 mpg. I fact I in Las Vegas for the holiday drove over from Los Angeles (AV area) last night did the drive in under 4 hr 55-95 mph the whole way 41 mpg

 

95 mph? Yikes. Are you in a hurry or do you just like going that fast?

 

Your Prius will do 115 mph if you like I run whatever mode depending upon what I feel like that day.
