Daimler Chrysler and Mitsubishi Motors introduced the first four-door Smart, in 2003. It was called the smart forfour.
The new, now old Smart ForFour was the first vehicle from the joint DaimlerChrysler/Mitsubishi Z-car project, based on the new Japanese Colt subcompact, which also included the European Colt.
The shared components developed by Mitsubishi include the petrol engines, rear axle, structural components in the vehicle underbody, the manual transmission and the emission and fuel tank system. Both vehicles will be built at NedCar in Born (Netherlands).
To save production costs, the Smart Forfour shared most of its components with the 2003 Mitsubishi Colt, including chassis, suspensions, and the
MIVEC petrol engines, three- and four-cylinder, ranging from 1.1 to 1.5L.
The car was produced at the NedCar factory in the Netherlands in conjunction with Mitsubishi Motors. This is the same factory that produced Volvo 340 cars in 1970s and 1980s.
It was reported in 2004 that the next Smart Forfour was designed to pass all U.S. safety and emissions regulations.
On June 30th of 2005 year Japan's Mitsubishi Motors Corp and DaimlerChrysler halted production of the Smart Forfour.
