The Fleet World MPG Marathon is the UK’s longest-running economy driving event. Covering two days, this year’s event took place in the Cotswolds and covered 350 miles of A roads and B roads.
Amongst the frugal city cars and superminis, Vauxhall’s V8-powered VXR8 registered 32.14mpg against a combined figure of 21mpg.
The Vauxhall VXR8 was driven by Top Gear’s online editor Chris Mooney with help from navigator Andrew Duerden.
Chris Mooney said: “Andrew and I are, as they say, over the moon to win the overall best percentage improvement in the VXR8.
“It just goes to show that the person behind the wheel can make a massive difference to fuel costs and carbon emissions. And, of course, that a 6.2 litre V8 is a very sensible choice of engine in the right hands.”
A number of vans also took part in the Fleet World Marathon such as the Renault Trafic, the Fiat Fiorino, the Citroen Nemo and the Ford Transit.
The Renault came first out of the van models with its figure of 59.11mpg showing a 54.73 per cent improvement over its original figure of 38.2mpg.
The Ford Transit also impressed, by winning both the 2800kg and 3500kg classes.
MPG Marathon organiser Ross Durkin said: “The people who took part are some of the best economy drivers in the world.
“But the overall aim of the event is to raise awareness among normal motorists that a few simple techniques – such as better anticipation of the road ahead, smooth acceleration and correct use of gears – can bring about significant savings at the fuel pumps”.
