The team of Johnny Horan and Alastair Lindsey achieved the hugely impressive figures in a Mazda2 car on a 100 kilometre route between Kill in Co Kildare and Templeogue in Dublin.
But they were pushed all the way in the test by brothers and journalists Conor and Brian Twomey who achieved 3.47L 100kms (81.312 miles per gallon)
The Mazda/Topaz Drive Safe, Drive Smart initiative is aimed at encouraging drivers to drive safely at moderate speeds and to adopt smarter driving techniques which make a dramatic impact on a vehicles fuel economy.
The car used in the test was the new Mazda2. Pictured above are the group of participants, with Noel Brett from the Road Safety Authority (first on left, standing), Conor Faughnan of AA Roadwatch (second on left), David McGonigle, MD Mazda Ireland (third on left) and Danny Murray, CEO Topaz (fourth on left, coffee in hand).
