The Audi A6 2.0 TDI ultra has taken down the Guinness World Record for travelling the most countries on one tank of fuel. Driven by motoring journalist Andrew Frankel and racing driver Rebecca Jackson, the frugal mid-size sedan managed to cover no less than 1,158.9 miles (1,865 km) after being driven almost nonstop for nearly 28 hours through the following countries: Netherlands, Hungary, Belgium, Luxembourg, France, Switzerland, Lichtenstein, Austria, Germany, Italy, Slovenia, Croatia, Bosnia and Serbia.
During this long journey, the Audi A6 2.0 TDI ultra managed to return 75.9 mpg so the large fuel tank with a capacity of 73 liters proved to be big enough to last for a significant amount of time. Interestingly, the car’s trip computer was showing 0 miles when there were just 16 miles to go before entering the last country.
It should be mentioned the route was carefully established by RAC to make sure the car consumes as little fuel as possible so they tried to avoid congested towns, cities and mountains. Speaking of the vehicle, it has a 2.0-liter 4-cylinder turbodiesel engine with 190 PS (139 kW) and has an official mpg figure of 69 mpg, with corresponding CO2 emissions of 109 g/km.
