I am a new 2019 Clarity PHEV owner. I have had the car for 1 week and my EV range estimates have been 42, creeping up to 44. When I picked up the car I drove 130 miles on the interstate freeway in HV mode to get home, and then it's been few miles commute to work daily in ECON mode. I have the climate set to auto and it uses the heater to warm up the car. I am curious to see if the EV range estimate will go up with mostly non-highway driving (less than 45 mph).
