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.
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.
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?
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.
