2020 Toyota Prius gas mileage
I just purchased a 2020 Toyota Prius and drove 352 miles (mostly all interstate). Speeds varied from 55, 65, 75. Total average mpg was 38.9. The dealer told me that cold weather decreases mpg. Is this true? Our trip started with temp of 23 degrees in Sioux Falls, SD and ended up in Rapid City, SD at 50 degrees. This is the 5th Prius we have owned and I am feeling there is a problem.
Give it some time to break in.
