Honda is planning to be the new Guinness World Record holder for fuel efficiency as the company recently announced that they will undergo a 8,500 mile (13,679km) drive across 24 countries in Europe.

Scheduled to begin on June 1, 2015, Honda will be using a 2015 Civic Tourer fitted with a 1.6-liter i-DTEC diesel engine that the automaker claims as their 'super-efficient' powerplant. The automaker also stated that this particular diesel motor consistently outperformed its claimed fuel efficiency figures and thus, the company plans to put it to the ultimate test by trying to break the Guinness World Record.

The car will be driven by two members of Honda's European Research & Development (R&D), Fergal McGrath and Julian Warren. The two volunteered for the long journey and have committed in driving on average 370 miles (595km) each which can take up to 7.5 hours according to the company.

“We are very much looking forward to the record attempt, and while we’re excited we’re both a little nervous about the scale of the task that awaits us. A huge amount of planning has gone into taking on this challenge and we look forward to what we hope will be a successful result when we return to Brussels on June 25th. But we’ve got more than 170 hours behind the wheel to contend with first,” said McGrath.

Their journey will begin in Aalst, Belgium as the duo will navigate the continent in a clockwise direction before making their return trip to Belgium 25 days later. The other 23 countries that the pair will cover include: Austria, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain and Sweden.

As it is a Guinness World Record attempt, several rules and regulations are to be strictly implemented during the journey. For starters, the car must a standard model with no modifications whatsoever apart from the provided tracking device, GPS and other telematic devices. The pair are only allowed to travel by road and that they should enter each of the 24 countries. The drivers must also collect a range of evidence like: mileage logbook, GPS readings, video, photographs and independent witness accounts.

Lastly, the fuel tank of the car has to be filled to its maximum level in each stop to ensure no unfair advantage by reducing overall weight on the automobile.

“Since its launch in 2013 we have seen the 1.6 i-DTEC engine consistently over-perform on real-world fuel efficiency in our Civic, Civic Tourer and CR-V models, and this is our opportunity to put it to the ultimate test on a huge scale. We are very confident of a great result and we wish the team all the very best of luck as they take on the challenge,” said Philip Crossman, Managing Director of Honda UK.

The current Guinness World Record holder for the lowest fuel consumption are Wayne Gerdes and Bob Winger from the USA. The duo completed the feat last June 2013 across the 48 states in a Volkswagen Passat TDI. They were able to rake in 8,122 miles (13,071 km) while averaging 33.16 km/l of fuel.
