As I recall, there were 2 issues on the 42V

1.  Higher voltage FETS were too expensive

2  42V incadescent light bulb life in automotive environment was too short.

Both these are no longer issues.

Chuck,  I did an article on 42 volt systems 7-8 years ago, and the concerns were $ and safety. It looked at one point like 42v systems would be gaining a foothold, but within a year or two the tide had turned. Any idea if these factors (I'm sure $ is important) are still front and center? Thanks.

You nailed it, tekochip. That's the driver.

I detect a trace of irony in your question, but as I think you are pointing out here, they're not being coerced. There was no mandate. Start-stop came into being as a way of lowering emissions, and then European consumers just wanted it.

They pay more for fuel.

Extraordinary "in Europe, approximately 50 percent of the cars produced this year will be start-stop vehicles". That's about as universal as it gets in a free market. How are the EU consumers being coerced?

Incremental is good

Chuck, it seems that this would be an incremental increase (15%) that would be a lot less costly than a full hybrid or EV.  This is a good thing.  Couple that with increases in efficiency in the ICE and increased aerodynamics and you can easily reach the CAFE goals for a very reasonable price. 

I am also impressed that this system would run the A/C and other heavy loads on the engine.  The disturbing trend in autos today is increased power in the same displacement.  If instead of increasing power by 20%, the displacement was decreased by 20%, then fuel efficiency would go up almost for free (no new, exotic technology).  For example, the Chrysler 3.5L V6 that was first used in their LH cars produces 250HP.  As a comparison, my dad's 1970 Olds Delta 88 with a 5.7L (350 CuIn) V8 produced 250HP.  The newest 3.5L V6s produce about 300HP.  Now, if we just use a 3L at 250HP, then gas mileage would go up accordingly.  Believe me, 250HP is enough for a 3,600lb automobile to go fast.  If you take the load of the A/C and other items off the ICE, then you can lower the HP even more for the same performance. 

Why hasn't this happened?  Maybe the standards should be tighter, sooner.
