Honourable mention should also go to Saab for their Aero-X prototype, a 500hp supercar which is designed to run on 100% ethanol...

I think Saab is definitely shooting for biofuels more than hybrids, but I think if anyone could pull off a hybrid biofuel car, it'd be Saab, because as a consumer base, we Saab owners are a strange bunch who enjoy strange features and technologies, and don't mind paying half again the price of a Japanese or American car to get Saab quality and design. I don't have the money for one now, but since I'll never buy anything other than a Saab, I'm saving up for a diesel Saab special import from the UK, since they're not available here in the US. But if this concept car goes to production, it'll be at the top of my list.
