I attribute the trend of newer vehicles going to electric to many of the newer cars being front-wheel drive, thus having to have an electrical fan. So, it is sort of off-the-shelf technology to put electrics even in rear-drive cars. Like I said originally, I think it is more or less a coin flip as to which takes more power, and I have to think the mechanical is more reliable.
