What is the smart forfour?
The smart forfour is a small four-door city car that seats four. It gives the smart range’s compact urban idea a more practical shape than the two-seat fortwo, with room for passengers in the back.
The second-generation forfour, known as the W453, ran from 2015 to 2021. It shared the smart family’s rear-engine layout and used short overhangs, contrasting body panels and the brand’s Tridion safety cell. Mercedes-Benz developed it with Renault, and the car was built in Slovenia.
Engines and power
The range included 0.9-litre and 1.0-litre engines, with petrol and electric versions. Across the versions registered in the EU from 2015 to 2016, output ranged from 52 kW (71 PS) to 80 kW (109 PS). The most common listed configuration was the 1.0-litre petrol with 52 kW (71 PS), followed by the 0.9-litre petrol with 80 kW (109 PS).
Fuel consumption and CO₂
The forfour’s official fuel-consumption and CO₂ figures depend on the version and test procedure. European results use WLTP or the earlier NEDC procedure, and the two tests are not directly interchangeable.
Where was it sold?
In the European Economic Area, registrations span 2015 to 2016. The 1.0-litre petrol version led the listed configurations, followed by the 0.9-litre petrol with 80 kW (109 PS).
