2019 Honda Insight EX (White Orchid Pearl)
We've not experienced single digits in Boston yet unless wind chill is factored in. Don't think wind chill affect cars. When it was under 20F earlier this week I needed the heater on. If I get on the highway I use the passive heater trick.Just an update, in single digit temperatures, there is almost no difference from cold start with or without heat usage. Drive to work was 25.6 mpg, drive home without heat 28.2 mpg. My drive to work is usually 3-4 mpg less due to terrain.
PS I don't recommend not using heat at these temperatures, the drive home I was fighting with a windshield that was freezing over on the inside. I'm also sure that tire pressure was a factor, the last time I checked tire pressure it was ~45* ambient temperature.
I'm trying to see if lowering the heater temp improves mpg(might test this later tonight). I usually set it to 65F but 60F seems comfortable enough for me at 36F outside temp. I managed to get 58.2mpg on a warm engine traveling 8 miles yesterday doing that. Previous trip was only a 1 mile drive so I've nothing to compare it to right now.
