300MPG Hybrid Gas-Electric in 2009 ?!

This has been all over the internet the past few days. I first saw this in this TomsHardware article which normally just covers computer hardware technology. Also, see this Engadget article. Aptera, a small electric vehicle startup from California, will be releasing an electric vehicle (Typ-1) in late 2008. Then in 2009, they plan to produce a gas-electric hybrid that will get a whopping 300MPG! This sounds a bit skeptical until I saw the PopularMechanics test drive article and video.
