Nissan Micra DIG-S
At the heart of the newest Micra lies a truly remarkable engine, specifically created to meet the low emission and everyday performance demands of the modern world. It gets its name from a combination of direct fuel injection and supercharging technology: Direct Injection Gasoline-Supercharger.
But as well as delivering ultra low CO2 emissions, the lightweight, low-friction 1,198cc DIG-S three-cylinder unit produces the power expected from a conventional 1.5-litre four-cylinder engine.
Further efficiency gains are made thanks to the adoption of advanced engine management systems with Start/Stop and energy regeneration.
The secret to its remarkable figures is the adoption of two technologies specifically designed to reduce losses and enhance combustion efficiency - the Miller combustion cycle and a supercharger.
By minimizing heat, friction and pumping losses as much a possible and combining it with an unusually high compression ratio of 13 to 1, Nissan's engineers have created an engine that sets the standard for the rest of the industry.
