Volkswagen's Passat TDI challenged and broke the existing Guinness World Record® achievement for the "lowest fuel consumption-48 U.S. states for a non-hybrid car." The two drivers averaged 77.99 mpg while piloting a 2013 Passat TDI® Clean Diesel on an 8122-mile, 48 contiguous state drive leaving from and returning to Volkswagen's Herndon, Va. headquarters.
