smart fortwo (W451) (W451)

The second fortwo grew by nineteen centimeters — just enough to satisfy American crash regulation and finally put a smart on sale in the United States.

Built at Hambach from November 2006, it used a 1.0-liter Mitsubishi-designed three-cylinder in naturally aspirated and turbocharged forms alongside an 800 cc OM660 CDI diesel that was, for a time, the lowest-CO₂ car on sale anywhere. A battery-electric smart fortwo electric drive followed in 2009.

The contrasting tridion safety cell remained the visual signature; production ran to 2014.
