Hybrid killers: Cheaper gas, tighter credit and a weaker economy

Insight's Paris debut stifled by auto sales decline

Auto sales are crashing. Dealers are closing their doors. Consumers can't finance a new vehicle without perfect credit or a big wad of cash. Gas prices are still high, but falling.

So, what's selling? Small, cheap cars continue to move. Most other vehicle segments are falling drastically. And, if not for incentives, they'd be DOA.

Hybrid cars are still moving, but supply is limited. But what happens mid-next year when supplies of hybrids increase drastically?

If the economy is still faltering, as gas prices continue their slide, will these hybrids sell? Will cheaper gas and a weak economy take the hype out of hybrid vehicles without serious pricing incentives?
