Smart is going all-in on zero-emission motoring – its Fortwo Coupe, Cabrio and Forfour models have been refreshed and made solely electric.

Ahead of their public debut at the 2019 Frankfurt International Motor Show next week, the Daimler-owned manufacturer revealed its trio of cars will drop their three-cylinder petrol options and will only be offered in purely electric ‘EQ’ form.

The powertrain, present across all Smart vehicles, consists of a 79bhp rear-mounted electric motor mated to a 17.6kWh battery, offering a range of between 91-99 miles (in the Fortwo Coupe model).

The move follows on Smart announcing it would transition into a ‘fully electric urban mobility brand’ back in 2018. In addition, it’s not the first time we’ve seen an EV from the German firm – in fact, it’s offered an all-electric option in every generation of its cars since 2007.

What’s more, back in 1972, during the original deliberations on an urban traffic vehicle, the concept was solely battery-powered.

Apart from this, the entire Smart range has been given a mild makeover, with models now featuring a redesigned radiator grille and optional full-LED headlamps, among other design tweaks.
