If the Prius and other hybrid electric cars leave you dissatisfied, know at least that Porche is tinkering with an electro-mechanical flywheel developed by the Williams Formula One team subidiary Williams Hybrid Power. I drove a Prius once, a rental. Couldn’t wait to get out of it. A Porche 911 sounds like a lot more fun–and probably better engineering too. Video at the link.
