Hey, I got an email from a nice man at Porsche, which is encouraging. Looks like they are developing a hybrid Cayenne ready for release by the end of the decade. They also have the facility for a 25% bio ethanol mix in their latest Cayenne model. Looks like the big guys are doing something, but please Porsche, let me get my hands on a lithium 911 or boxster, similar to that uber electric car, the Tesla.
You might want to check these guys out.
