A smart fortwo gave its high-powered opposition plenty of ‘fuel for thought’ when it sprinted to victory in the Cannonball Run – a 4830km dash across Europe inspired by the famous 80s film starring Burt Reynolds.

Life-long friends David Ward and Adrian Hull, from Essex, beat a long list of six-figure supercars in their five-year-old, second-hand smart fortwo BRABUS, which was the smallest car in the 40-vehicle field.

The event, which started at Sandown Park and took in France, Portugal and Spain with a finish in Brighton, saw the duo awarded first place for completing the route at the exact stipulated requirement of an average of 61mph (98km/h).

It was the smart’s impressive fuel economy that really provided the edge for the 46-year-olds and their Union Jack-liveried smart. The performance version of the iconic smart range, which features a 700cc, 74bhp, three-cylinder turbo engine, is capable of 5.3L/100km when driven on the combined fuel cycle – a factor that enabled the car to spend less time at the petrol pumps than its thirstier rivals.

“The downfall of the bigger cars was that they were forced to stop so often, so while they kept overtaking us, we eventually went past them at the next petrol station when they needed to fill up again,” said David. “We kept at a decent speed and still averaged around 8L/100km.”

What made David and Adrian’s victory even more remarkable was the fact that their smart has all of its original specification apart from a re-mapping kit and upgraded suspension. Competing in their first event of this kind, they were also the only entrants without an in-car satellite navigation system – preferring a traditional European road guide instead.

“Having entered for fun and to raise money for the NSPCC, it’s fair to say that we were surprised to win and I suppose there is a ‘David and Goliath’ element to our victory,” admitted David. “I think the other drivers initially thought it was a hoax that a smart had entered but they gave us more and more credit as the week went on and, at the end, they were genuinely pleased that we won.

David and Adrian have automatically gained entry into next year’s Cannonball Run but are now planning further adventures in their smart car including next year’s Gumball Rally from Los Angeles to Miami and a drive from Land’s End to John o’Groat’s (the bottom of England to the top of Scotland) in just 12 hours.
