The new smart diesel model will enter right-hand drive manufacturing next February, meaning British drivers will be able to get their hands on the world’s most eco-friendly vehicle.
Using only 85.6mpg, the new smart can travel 670 miles on a tank, the equivalent of Dover to Prague.
It also releases the lowest CO2 emissions of any vehicle currently in production at just 88g/km.
Dermot Kelly, managing director of Mercedes-Benz Cars, said: "The cdi gives customers the whole range of smart benefits when driving in and around the city, with the added bonus of low cost, long distance motoring.
"Our retailers are reporting heightened interest in the iconic two-seater; registrations are buoyant and we think the addition of the smart cdi to the range early next year will give added momentum," he added.
Drivers can get 45hp from the three-cylinder engine and the model will be available as a coupe and a cabrio.
