The RAC and Audi have set a new Guinness World Record by driving to 14 countries on a single tank of fuel.

Motoring journalist Andrew Frankel and racing driver Rebecca Jackson drove an Audi A6 Ultra 1,158.9 miles almost non-stop for nearly 28 hours from the Netherlands to Hungary, passing through Belgium, Luxembourg, France, Switzerland, Lichtenstein, Austria, Germany, Italy, Slovenia, Croatia, Bosnia and Serbia.

The road trip began in Maastricht at 9.48am (GMT) on Tuesday, June 9, and ended in Hungary at 12.44pm (GMT) on Wednesday, June 10, with the pair averaging 75.9mpg from the A6, which has a 73-litre fuel tank.

The route was plotted by the RAC to avoid the fuel-sapping effects of built-up, congested towns, cities and mountains.

Event coordinator Simon Williams said: "The car was not modified in any way as it comes with fuel-efficient, low rolling resistance tyres as standard.

"This really shows how far it’s possible to drive in a modern vehicle and that the price of fuel – albeit cheaper on the continent – should not put anyone off exploring Europe by car.”
