With CO2 emissions of only 95 g/km, Nissan’s all-new Micra DIG-S has one of the cleanest petrol engines in the world. To achieve this, the Japanese firm's engineers used a 1.2-liter three-cylinder unit fitted with a supercharger and direct injection, which can be coupled either to a manual transmission or a CVT automatic gearbox.
The powerplant uses the Miller cycle and with a peak output of 98HP and 142 Nm (105 lb-ft) of torque, it’s said to be on par with a conventional 1.5-liter four-cylinder unit. Other technical highlights include the 13:1 compression ratio that increases combustion efficiency, the reduced heat, friction and pumping losses thanks to fewer moving parts, and advanced engine management systems with Start/Stop feature and energy regeneration capabilities.
