The present record is held by a Honda Civic Hybrid.
November 22nd, 2008 marked the beginning of a historic effort by three highly regarded Hypermilers to break a World Record established just two months prior. Completed September 25th, this record was achieved by Australians John and Helen Taylor in a 2009 VW Jetta 2.0L TDI sponsored by Volkswagen, Shell, and Navman. The Guinness verified record of 58.82mpg (US) set a new standard of efficiency in real world (official) mileage while traversing the country. Could our team of intrepid drivers overtake this lofty number in spite of unpredictable winter conditions?
Not only did they overtake the target mileage, they exceeded it by 11.5% to establish the new record at
68.54mpg (US) in a 2009 Honda Civic Hybrid carrying three people and their luggage through all 48 contiguous states!
