A direct injection unit with a supercharger – hence the car’s name: Direct Injection Gasoline-Supercharger (DIG-S) – the engine is the embodiment of Nissan’s PURE DRIVE strategy, delivering sparkling performance, frugal economy and exceptionally low emissions.
Technical innovation has been packed into the engine. The Nissan DIG-S uses the Miller cycle and direct petrol injection to raise the compression ratio to 13 to 1 for greater combustion efficiency and a supercharger for instant throttle response and added power. As well as delivering ultra low CO2 emissions, the lightweight, low-friction 1,198cc three-cylinder unit produces the power expected from a conventional 1.5-litre four-cylinder engine.
Nissan Micra’s city car credentials have been honed over decades of class leading models. Bristling with new technologies and based on a brand new platform, Europe-bound examples of the fourth generation Nissan Micra are built at an entirely new facility in India. It is also built in China, Mexico and Thailand and is sold in 160 countries around the world.
The new Nissan Micra DIG-S is available in one body five-door body style, three trim levels – Visia, Acenta and Tekna – and with a choice of two petrol engines. As well as the DIG-S, there’s a normally aspirated version of the 1.2-litre engine, developing 59kW (80PS).
By minimising heat, friction and pumping losses as much a possible, Nissan’s engineers have created an engine that sets the standard for the rest of the industry. Its three-cylinder configuration gives many benefits including less weight and further reductions in friction loss, thanks to having fewer moving parts. Further gains are made thanks to the adoption of advanced engine management systems with Start/Stop and energy regeneration.
The Direct Injection Gasoline-Supercharger (DIG-S) engine produces 72kW (98PS) and 142Nm, while CO2 emissions are 95 g/km for the manual version and 115 g/km for the CVT version. Maximum speed is 180km/h for manual. Combined cycle fuel economy figures for the manual Visia version is 4.1 l/100kmh *.
In common with industry practice, these headline figures refer to the entry-level version – Visia – as higher levels of equipment found in plusher models mean extra weight which affects emissions performance. But such is the efficiency of the unit that the most popular version, Acenta, also promises an outstanding CO2 figure: just 99 g/km in manual form.
This remarkable engine makes sub 100 g/km emissions performance easily accessible while low cost of ownership make it a serious alternative to a comparable diesel… with the added bonus of greater refinement. Its first appearance powering the new Nissan Micra makes for an irresistible combination.
