While I'm always in-awe of class-leading engineering, sometimes adapting to new opportunities makes a lot of sense.
I just discovered that Prevost premiered the launch of using two duplicate sets of electric fans to handle all engine cooling needs. https://www.prevostcar.com/news-and-medi...re-prevost
When you think about it, it totally make sense:
* I can't think of a late model car that doesn't have an electric powered fan
* Complete, variable control only runs them as hard as needed for much better efficiency.
* The HP gain at the wheels could be incredible (reported in the area of 75!)
* Service-ability must be MUCH easier
* Redundancy over single, fan-belt operated system is huge
* Clever use of reverse motors to clear snow (!) but even having them stop operation to clear debris on a regular interval to allow a plastic bag to no longer be suctioned to the grill
I'm sure this makes the electrical management a bit more challenging, but I would guess it's a strong net gain. Is anyone aware of Newell adopting this?
Just curious.
