Volkswagen Passat Sets Single-Tank Efficiency Record

An Australian couple has set a new record for single-tank fuel economy this week, making the more than 1,600-mile trip from Houston, Texas to Sterling, Virginia on just one tank of gas. The duo used an American-built 2012 Volkswagen Passat SE TDI Clean Diesel to set the new mark, beating the old one (also set in a diesel-powered Passat,) by 99.5 miles.

Over the course of their journey, Helen and John Taylor drove 1.626.1 miles, using 19.3 gallons of diesel and averaging more than 84 mpg. Their fuel costs averaged out to less than 5 cents per mile, whereas the average new vehicle currently sold in the U.S. will cost its owner more than three times as much to drive.

The couple used a regular, stock Passat TDI (which is rated at 30 mpg in the city, 40 mpg on the highway, and 36 mpg combined) for their drive, but were able to use so-called “hypermiling” techniques to get even better fuel economy from a car that is already one of the most efficient non-hybrid sedans on the road.

“The Passat TDI was the perfect car for the trip. It offers plenty of interior and cargo space, yet is frugal enough to help us achieve this record,” said John Taylor, in a press release provided by Volkswagen.

Though the Taylors have used a lot of Volkswagen-built diesels for their trips, their mission is about more than just promoting a single vehicle maker’s cars. Last year, they achieved nearly 75 mpg in a Toyota Prius hybrid driving across South Africa, and drove through every U.S. state in a Chevy Cruze Eco at an average of 64 mpg.

In fact, you might say that the couple have turned personal fuel economy into their life’s work. In addition to several record-setting attempts each year, the Taylors teach green-driving seminars through their Australia-based driving school, Fuel Academy. In all, the husband-wife team hold more than 90 world driving records.
