In May 2010 Suzuki announced that it will begin test-driving 60 Swift Plug-in hybrids in Japan by late 2010. The plug-in is powered by a 55 kW, 180 N·m AC synchronous motor and a 2.66 kWh Li-ion battery pack. Average fuel consumption, calculated by combining fuel consumption during operation on electric power from grid charge and fuel consumption during hybrid operation after depletion of the battery pack is 37.6 km/L on the JC08 cycle (88.4 mpg US, or 2.7 L/100 km). Grid charge time for the battery is approximately 1.5 hours @ 100V and 1h at 200V.
