After last year's update, the smart fortwo is all but unchanged for 2018. However, the family welcomes a new member this year: a cabriolet with an electric motor. Like the fixed-roof electric version, the cabriolet delivers 81 horsepower and approximately 155 kilometres of range courtesy of a 17.6-kWh battery. This model is the only electric car on the market available with a retractable roof.
