City performs remarkably well on the eco front. With an average of 117 g/km CO2 across the model line-up, its emissions are impressively low for a mini coupe. It’s worth noting that the line-up does not feature any diesel models, which typically produce less carbon dioxide than petrol engines with similar power outputs. The range is extremely frugal, averaging 58 mpg.

Although still a relatively new name in car making, smart is part of the Daimler-Chrysler empire, which includes Mercedes-Benz and Jeep. Build quality and engineering are both good and problems have been few and far between.
