Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 53 - 60 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

Pretty cheap to run. Depreciation is slight and gets lower as the cars age. Small turbocharged engine gives around 55 mpg. Insurance starts at Group 3, although the Brabus version falls into Group 9, which is a little pricey. All models fall into the lowest road tax band.

City is very eco-friendly and easy on the environment. With an average of 117 g/km CO2 across the model line-up, its emissions are impressively low for a mini cabriolet. 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.
