Here's another alternative -- a custom battery formulation for hybrids.

I'm sorry I didn't see your comment earlier, Ratsky. You raise an excellent point about decelerating to a crawl without stopping. There's been a lot of discussion about this and it's not clear how the auto industry will handle it. The most basic problem is synchronizing the starter motor to the powertrain's spinning ring gear during deceleration. Some suppliers say they can do it reliably now, but I don't expect to see this feature reach wide application for a while.

That's another advantage of the "motor-generator" with regenerative braking approach.  It's ALWAYS turning and doesn't need the solenoid/cog/etc. stuff.

I think start-stop is another way to improve gas mileage, especially at rail crossings. What I don't understand is why are we reinventing the wheel? Golf carts have been start-stopping for years. I don't hear anybody picking up on their technology. It works, use it.

Manufacturers of plastic parts recognize the potential of conformal cooling to reduce molding cycle times. Problem is, conformal molds require additive manufacturing (AM), and technologies in that space are still evolving. Costs also can be high, and beyond that, many manufacturing organizations lack the knowledge and expertise needed to apply and incorporate additive technologies into their operations.
