The evidence: rumor had it at the LA Auto Show that customers would soon have the option of buying a hybrid Toyota Matrix and a hybrid Pontiac Vibe; the 2009 Pontiac Vibe is made at NUMMI, a GM-Toyota joint venture manufacturing plant where the Matrix is also made; Toyota's already got its hybrid synergy drive -- so is GM working on a hybrid with Toyota, or will they use Toyota's hybrid tech to work in the Vibe?

The evidence is circumstantial, certainly. But it's possible. Lutz said at the recent Reuters Auto Summit that, no matter what GM thinks of hybrids, the company made a mistake letting Toyota get so far ahead with hybrids such that now the Japanese brand has become practically synonymous with hybrids and is perceived to be atop a green moral high ground. True, there's the Volt, and GM might not be doing anything with Toyota at all and it could just be a rumor. Or GM could surprise us with something completely new -- it wouldn't be the first time.
