Gavin Conway, a writer for the UK’s Sunday times, recently set out for a country drive. Quite the drive, in fact: his drive ended up lasting three days, on a three-day trip that took him from Maidstone, Kent, to the south of France, and almost all of the way back, on one tank of diesel.

The car: the BlueMotion edition of the Volkswagen Passat. The car Conway powered was the standard model, a 1.6-liter common rail TDI four-cylinder engine, which holds a 20.4 gallon tank for diesel.

Now Conway can brag that he’s in the Guinness World Book of Records for his 1,526.63 mile drive, apparently now the longest distance ever driven by a production passenger car on one tank of fuel.
