Passage: In 2004, Google formed the not-for-profit philanthropic Google.org, with a start-up fund of $1 billion. The mission of the organization is to create awareness about climate change, global public health, and global poverty. One of its first projects was to develop a viable plug-in hybrid electric vehicle that can attain 100 miles per gallon. Google hired Larry Brilliant as the program's executive director in 2004 and Megan Smith has since replaced him as director.In 2008, Google announced its "project 10100" which accepted ideas for how to help the community and then allowed Google users to vote on their favorites. After two years of silence, during which many wondered what had happened to the program, Google revealed the winners of the project, giving a total of ten million dollars to various ideas ranging from non-profit organizations that promote education to a website that intends to make all legal documents public and online.In March 2007, in partnership with the Mathematical Sciences Research Institute (MSRI), Google hosted the first Julia Robinson Mathematics Festival at its headquarters in Mountain View. In 2011, Google donated 1 million euros to International Mathematical Olympiad to support the next five annual International Mathematical Olympiads (2011–2015). In July 2012, Google launched a "Legalize Love" campaign in support of gay rights.

Question: How many miles per gallon can the plug-in hybrid electric vehicle get?
