    Shouldn't it be a diesel, isn't diesel a more apt choice for the volt's ICE's generator duty?

    Diesel is certainly more heat-efficient, but apparently only VW knows how to make a small diesel that can pass US emissions. The Opel version of the Volt (dunno if that's still on the table or not) was going to be a diesel hybrid.

    There might also be issues with smoothly engaging a diesel engine without making the electric motor stutter by momentarily sucking the life out of the batteries, I dunno. That 20:1 compression ratio takes a pretty strong motor to overcome.

    Easy to overcome, stand alone starter battery for the engine. :wavey:

    At least GM is using the more modern battery.

    Lithium Cobalt Oxide batteries definitely have the best energy density of any battery right now. I'd like to see more development on the Lithium Iron Phosphate chemistry, though, because it doesn't store free oxygen atoms inside the batteries when fully-charged, eliminating the risk of "accelerated combustion" that LiCO batteries have.

    In any event, it's nice to hear that their target goal is to simulate a 250hp V6, and that they're actually kinda sorta hitting the mark even in testing.

    That's a great solution for Europeans, but it runs contrary to American design philosophy and American drivers' expectations. You know that ammonia tank is going to run dry and get ignored for the next 50,000 miles.

    Interestingly, a 75/25 mix of diesel and biodiesel burns soot-free, according to experiments done by several cities around the country in their public works vehicles. Which is to say, the ammonia-injection solution is exactly one legislative bill away from being obsolete and unnecessarily-complicated.

    well. If you have a light on the dash that says,"REPLACE UREA", most consumers will heed it. besides, urea isn't too pricey
