I'm confused about this HCCI thing and maybe someone can help me. So does this HCCI process require an all new type of fuel, does it use diesel more cleanly and efficiently, or does it somehow use standard gasoline? I'm not an engineer, but if it is the third option (using regular gas), I've always understood the fundamental difference between diesel and gas is their resistance to combustion under pressure. Maybe someone understands this more?

Anyway... the move to RWD is a solid plan, so long as they don't stop their AWD push. AWD is where the market is headed and won't abandon older Acura customers who can't or don't want RWD.
