I don't know, I live in eastern Canada, modern cars don't seem to have much of an issue on the handful of -20 to -25 Celsius mornings we get every year, as long as the battery is in good shape. Even the 2007 Yaris we had up to 2018 never had an issue (after I replaced the dying battery). Now the -40 C weather they've been having in the prairies recently is a different issue, one I can happily say I don't have any experience with.
