smart used to have a model called the Roadster (and the Roadster coupé), which wasn't too much of a commercial success. The model wasn't ugly and had decent enough performance with its small 3-cyl engine thanks to its low weight. Still, smart only sold a little more than 43,000 units in the two years (2003-2005) that it was available.
Trying to give buyers more chances to get into a Smart, the company produced a four-seat hatch called the ForFour in 2004. It sold so poorly that the car was axed after just two years. In spite of that, Autocar says that parent Mercedes-Benz has filed patent papers for an embiggened Smart.
