Honda claims Guinness World Record for fuel efficiency, averaging 100.31mpg.
The feat was achieved during a 8,387 mile drive across 24 EU countries over 25 days.
Behind the wheel of a Honda Civic Tourer 1.6 i-DTEC for the entire journey were two members of Honda’s European Research & Development (R&D) team, Fergal McGrath and Julian Warren.
Under the rules the same two drivers must be in the car for the whole journey, giving Fergal and Julian the challenge of driving an average of approximately 380 miles, taking around 7.5 hours, each day.
The distance travelled is similar to the team driving to Australia from their home in the UK, stopping just nine times to refuel.
The car achieved an average of 932 miles on each tank of fuel, at a total fuel cost for the whole journey of just £459*.
The economy figures exceed the Tourer’s quoted efficiency of 74.3mpg by more than 25%.
The Civic Tourer was a standard model in every respect, with no modifications to create an advantage, in order to replicate ‘real world’ conditions.
