The smart cdi - the World's CO2 champion - has proved itself to be miles ahead of its rivals by winning this year's mpg Marathon with a staggering 96.81mpg.
Driven by smart eco-driver, Mick Linford the smart fortwo cdi passion coupe achieved this phenomenal figure over the demanding 360-mile route.
Acclaimed for its world-beating emissions of only 88g/km, the 45bhp cdi was the ideal choice for the two-day event that aimed to demonstrate how careful eco-driving can significantly reduce the fuel costs and CO2 emissions of the country's motorists and enhance safety.
Mick achieved the best ever mpg figure in the event's seven-year history and improved on the cdi's official combined fuel economy figure of 85.6mpg by over 13 per cent.
"I'm already looking forward to next year's competition when I hope to achieve another record breaking figure by exceeding the 100mpg barrier," explained Mick, who has previously driven a smart from London to Edinburgh on a single tank of fuel.
Dermot Kelly, Managing Director, Mercedes-Benz Cars, said: "smart has always been renowned for its unique style but this fantastic mpg result and its all-conquering emissions mean that smart now really leads the way when it comes to low ownership costs - a fact which is attracting an ever-increasing number of car buyers to the iconic brand."
From October 2009 the smart cdi costs from £9,227.55 on the road.Published 7 October 2009
