42V automotive system. What's the latest?
(OP)
I know the industry several years ago was picking up steam in designing future vehicles with 42V system.
I recently heard rumors that none of the major car manufacturers are actually doing it soon, and in fact some manufacturers abandoned completely future plans.
Anyone has info?

besides making smaller motors 42v allows much smaller diameter wires, less copper and less weight= big$
how soon it is coming I havent heard for certain but it isn't dead yet.

I'm not making a commission on this but this article is worth the few bucks it cost to download. The list of references at the end of the article will direct you to even more detailed information.

It describes the technical hurtles and economic challenges that ultimately quenched the initial industry enthusiasm. Basic component such as switches, relays, connectors and fuses needed re-design. Dual voltage schemes had additional complications. All these were solvable but re-design was expensive. Work-arounds were also found for many power-hungry devices that enabled keeping the 12 V system. According to the article, 42 V is not yet dead, just on life support. There are 2 vehicles in production and 2 more in the works.
Sorry for lack of details here, but I never liked to do book reports in school. :)
