the fourth generation Nissan Micra, first internally referred as W02A as the development code and as K13 for the model code, were unveiled on 1 October 2009. The car was first displayed at the 80th Geneva International Motor Show. It was sold in more than 160 countries, including Thailand from March 2010, India from July 2010, Europe from November 2010, and Indonesia from December 2010. It was the first March/Micra to be built in a North American plant, even though this generation did not have any sales in the United States. The K13 was however available in Canada after the spring of 2014. It is based on the V platform with a new 1.2-litre HR12DE (XH5) , 3-cylinder engine (the first for a March/Micra).

The car is expected to be fuel efficient, delivering 18 km to a litre of petrol. The new idling stop system is reported to improve fuel economy by 2.0 km/L. It features variable control of voltage for power generation with an alternator (including regenerative charging function with braking energy).
