Inhabitat: Earlier this year we told you all about the Porsche 918 Spyder hybrid concept car and now we get to tell you — as we so rarely get to do — that this concept car is about to become a reality! The Spyder which is surely to become the sexiest green car ever (sorry Tesla!) just got the green light to make this dream a real road eating machine. Porsche’s first ever plug-in hybrid goes from 0-60 in 3.2 seconds, gets 94 miles per gallon, and undoubtedly will have most of us drooling as it zips past us on our daily commutes. But why will we be drooling instead of riding inside, you ask? The price tag for the 918 Spyder is set at a whopping US $630,000!
