I don't think Ill brek the 60 mpg ine this summer. Mostly becauce of the silly tires the delivered with the car.
Also I live in a relative cold climate, and this car likes it warm. Summer peak temps has been reached, and from here on temps will start to decline, and milage with it.
The car likes warm starts. With ambient temps close to 30 deg. C, warm up time is almost none, as the hybrid drive kiks in with coolant temps at 40 deg. C or above.
Also the Yaris Hybris / Prius C lacks the better areo design of the back that the Prius has, which means that wind resistance is bigger, thus lower milage.
The car has a lot of potential though. What could be done was some short of Kamback or rear top spoiler, smaller side mirros - as those on the Yaris are HUGE - and a bellypan, as Toyota didnt make that to keep price down. Tires with lower rolling resistance will give at leat 1 mpg if not more.
No time at present to make mods, but as I plan to keep the car for at leat 8 year, there be plenty of time.
One other thing could be in play. I might have underestimates the break in milage of the car. I guessed it to be areoud 3.000 miles, but as mpg numbers has continues to climb at the car nears 7.000 miles, I suspect that the break in could be as long as 5.000 miles.
