Terrible Efficiency in the Rain?

That is likely the second largest drain… I am going with rolling resistance being #1.

Exactly, increased rolling resistance because of the standing water is by far and away the greatest culprit of range reduction.

It baffles me how people will understand that rolling resistance of wider/grippier tire will reduce range in the dry but then totally discount the tremendous amount of additional energy it takes to drive through even an 1/8 or 1/4” of water on the road. Add some real rain and downpours and now you’re really using extra power.

From my research, driving in very wet conditions can increase rolling resistance by up to 40% due to the additional hydrodynamic forces created by the tires pumping water. The tread design has a big impact, large water channels will reduce the energy required. Water depth is also a factor. Doing some calculations for the Mach-E this would result in a potential consumption increase of about 70 Wh/mi (RR is mostly constant with speed).

My suggestion is that the vehicle have to run both A/C and heater at the same time to give you dry warm air, otherwise your windows will fog.
