I like the quite warm, but not hot of the 2019 compared to extreme cycling of the 2015. I think I do notice the steering wheel in the 2019 gets hotter if cabin heat is on now that someone mentioned it. I need to do some more testing when the next cold front comes through.
Edited to add:. Either 2015 or 2019 is better than using my heated motorcycle gloves and vest in the 2011 to avoid excess power consumption in the water heater.
