Google.org Creating For Profit Hybrid Cars

In a New York Times article named Philanthropy Google’s Way: Not the Usual, describes how Google.org is actually a for-profit company, unlike the “Google Foundation” which is part of Google.org. Google.org is actually “consulting with hybrid-engine scientists and automakers” to design a new “an ultra-fuel-efficient plug-in hybrid car engine that runs on ethanol, electricity and gasoline.” I guess we can call it the Google Car? The goal of this Google car is to have these cars exceeds 100 miles per gallon. I wonder what colors these cars will come in?
