Apparently not happy with collecting over 40 world driving fuel economy records, the husband and wife team of John and Helen Taylor – also known as “the world’s most fuel efficient couple” – have been back on the road to claim the world record for the longest distance traveled on a single tank of fuel. The record 1,626.1 mile (2,616.95 km) journey was achieved in a stock 2012 Volkswagen Passat powered by a 2.0-liter TDI Clean Diesel inline four-cylinder engine with a six-speed manual transmission.
