Casual follower of e-drivetrain technology on this end. A lot of talk recently of 48-volt Mild Hybrid Systems have caught my eye. The question begs who is working on it ( many majors, they have hinted about it SAE papers, Ford for example, etc ) and will this Caddy reemerge with this 48v system in the future and who else?

If fuel prices stay low, the industry is gonna be in a real dilemma. They are investing tons of capital to design and develop vehicles to meet the (very high) govt mandated fuel economy levels.
And people are wanting to buy pickups and SUVs.
