As Metro said, yes, Otto versus Attkinson cycle.

As someone on here told me, regenerative braking is still braking. This kind of gets us into the debate between coasting in-gear (DFCO) versus EOC. For my normal commute to work, I know that if I maintain the speed limit (40 mph, although my GPS shows 37), I need to start coasting two blocks before the intersection or I will need to brake. I can EOC or stay in-gear a little longer and hope DFCO kicks in. In a hybrid, the DFCO would regenerate, but also slow down faster, but isn't it more economical to time the light and never brake, regenerative or otherwise?

I actually do not think that hybrids are cost-effective long-term, but I want one anyway. I am not able to drive up to Mom's house regularly, but there are a few mountains in between. When people say things like

http://ecomodder.com/forum/showthrea...tml#post370353, we execute a Palm Face maneuver and explain downshifting. I rarely need to use my brakes driving down mountains, but only if I stay below the speed limit; otherwise, engine braking drives revs to very high RPMs.

I only want a hybrid for mountain and canyon driving. Let me quietly use regenerative braking to give me a boost back up the hill. The rest of the time I will just try to plan well and avoid braking.
