What is it?
It's the all-new second-generation Smart Forfour, fitted with the firm's latest 'Twinamic' dual-clutch six-speed automatic gearbox and paired with the 0.9-litre turbocharged motor. It sits at the top of the Smart range.
We've sampled the Forfour previously on UK roads, but that version was propelled by a 70bhp 1.0-litre three-cylinder normally aspirated unit and mated to a five-speed manual gearbox.
As tested here in flagship Proxy trim, the Forfour is a generously equipped four-door city car. It gets two-tone leather upholstery, climate-controlled air conditioning, Bluetooth, USB connectivity, a panoramic roof, heated front seats, electric windows, lane-keeping assist, sports suspension and 16in alloy wheels all as standard. If you want your Forfour to swap cogs by itself you'll have to stump up an extra £995 for the privilege.
Smart's sport pack is offered as standard on the Proxy trim, though. It gains 16in alloy wheels painted in black, a leather multi-function steering wheel with mounted gearshift paddles (if the auto 'box is specified), suspension further lowered by 10mm, sports pedals and a chrome-plated tailpipe.
The Smart Forfour measures 3.5m-long, 1.6m-wide and 1.5m-high. To the eye, it doesn't appear that small, but the tape measure doesn't lie. It's still 4.5cm shorter and 3.5cm narrower than a Volkswagen Up. That combined with a remarkable turning circle of 8.65m compared with the Up's 9.8m means it should be almost comically agile in urban areas.
