Earlier this week we talked about a collaboration between Audi and RAC to try and take down the Guinness World Record for travelling to the most countries without refueling. They actually did it as motoring journalist Andrew Frankel and racing driver/TV presenter Rebecca Jackson managed to go through no less than 14 countries.
They drove nearly non-stop for almost 28 hours and covered 1,865 km after starting in Netherlands then going through Hungary, Belgium, Luxembourg, France, as well as Switzerland, Lichtenstein, Austria, Germany, Italy and then Slovenia, Croatia and Bosnia before coming to an end in Serbia.
The long journey was completed without refueling the tank which can hold up to 73 liters of diesel and in this trip they managed to do a very impressive 26.8 kmpl, a figure which is actually better than the official numbers released by Audi. It was a very intense trip especially towards its end as just 26 km before entering the 14th and final country the car’s trip computer was showing 0 km.
To travel for the longest distance as possible without having to refuel, RAC had to carefully select the route and they did it in such a way as to avoid congested cities which would have greatly affected the Audi A6 2.0 TDI ultra’s fuel economy. The mid-size sedan has a four-cylinder, 2.0-liter turbodiesel engine developing 190 hp and 400 Nm sent to the front axle through a six-speed manual gearbox or an optional seven-speed S tronic automatic transmission which enables the frugal executive model to emit just 109 g/km of CO2.
As a final note, Audi is also selling another A6 2.0 TDI ultra version in select markets with the same engine but detuned to 150 hp and coupled to the same two gearboxes. Moreover, there is another ultra-badged version which has a 1.8 TFSI turbocharged gasoline engine with 190 hp teamed up with the aforementioned S tronic.
