Honda has officially set a new world record for fuel efficiency after one of its cars covered 8,387 miles across 24 EU countries – using just £459 of diesel.
Two amateur drivers spent 25 days behind the wheel of the Honda Civic Tourer 1.6 i-DTEC, which recorded an average of 100.31 miles per gallon.
Fergal McGrath and Julian Warren stopped a total of nine times to refuel during their journey, which equalled the distance of driving from the UK to Australia.
The car, which was a standard model without any modifications, achieved an average of 932 miles on each tank of diesel, a fuel cost of £459 in average UK prices.
Mr McGrath and Mr Warren, both members of Honda’s European research and development team, set off from Aalst in Belgium on June 1 to navigate the continent in a clockwise direction.
They returned to the start point on June 25 having exceeded the Tourer’s quoted efficiency – 74.3mpg – by more than 25 per cent.
The drivers were presented with the Guinness World Records title for “lowest fuel consumption – all 24 contiguous EU countries (all cars)” at Honda in Swindon, Wiltshire.
Mr McGrath said: “It was tough, but we really enjoyed it, and setting this new Guinness World Records title has made all of the hard work worthwhile.
“This was a huge team effort so I’d like to thank everyone involved for all of their commitment and support.
“After spending so much time behind the wheel, Julian and I are just happy to be back behind our desks for a while.”
The official title is measured in litres per 100km and miles per gallon, calculated over the entire journey.
Under the rules, the same two drivers must be in the car for the whole journey.
