Compact city cars are often the number one choice for those seeking a balance between agility and efficiency. In this segment, a special place occupies Nissan Note, and its version with index DIG-S attracts attention with its unique combination of small engine displacement and high power density. This hatchback offers the driver dynamics uncharacteristic of cars of this class, while maintaining low operating costs.
DIG-S (Direct Injection Gasoline Supercharger) technology allows Nissan engineers to create a power unit that looks like a classic naturally aspirated engine, but works on the principle of turbocharging. Owners Nissan Note they note that the car feels great in dense city traffic, where instant acceleration is valued higher than top speed on the highway. However, before purchasing, it is important to understand all the nuances of operation.
Many buyers are wondering: is this engine really more economical than its usual naturally aspirated counterparts? The answer lies in the correct driving style and competent maintenance. Turbocharging in combination with direct fuel injection, it makes it possible to reduce consumption during quiet driving, but with an aggressive driving style, the advantage is leveled out. Let's take a closer look at what is hidden behind this technology.
Technological heart: How the DIG-S motor works
The heart of the compact hatchback is a 1.2-liter three-cylinder petrol engine equipped with a mechanical supercharger. Unlike conventional turbines driven by exhaust gases, it uses a belt drive from the crankshaft. This solution eliminates the so-called “turbo jam” - a delay in air supply when the gas pedal is sharply pressed. As a result instant response pedals ensures predictable behavior of the car in all situations.
The direct fuel injection system allows gasoline to be supplied directly into the combustion chamber at high pressure. This promotes more complete combustion of the mixture and reduces emissions of harmful substances. Engineers Nissan ensured that the three-cylinder unit operates quite smoothly, minimizing the vibrations inherent in such a design. Combustion efficiency is a key factor in achieving the stated efficiency indicators.
It is important to note that the supercharger comes into operation at low speeds, providing enough torque for a confident start from a standstill. Engine power is about 98 horsepower, which is an excellent indicator for a 1.2-liter volume. However, high thermal load requires careful monitoring of the cooling system.
Real efficiency and dynamics on the road
The main promise of the manufacturer is to reduce fuel consumption without losing dynamics. In a mixed cycle Nissan Note DIG-S consumes about 5.5–6.0 liters per 100 kilometers. This is an impressive figure for a car that does not require constant gas savings. In city mode, consumption can fluctuate between 6.5–7.5 liters, which is still better than many competitors with naturally-aspirated engines of 1.5 or 1.6 liters.
Dynamic performance is also impressive: acceleration to 100 km/h takes just over 11 seconds. For a city hatchback it's quite peppy. Thanks to the low weight of the body and the efficient operation of the supercharger, overtaking on country roads does not cause concern. Acceleration accessible from almost any speed, making driving easy and comfortable.
However, it is worth considering that savings depend on operating conditions. If you often sit in traffic jams with the air conditioning on, your fuel consumption figures will be higher. In addition, the use of low-quality fuel can lead to detonation, which is dangerous for a forced-induction engine. It is critically important to use gasoline no lower than AI-95 to ensure stable operation of the system.
- ✅ Fuel economy achieved through direct injection and optimization of supercharger operation.
- ✅ Dynamics surpasses many atmospheric analogues in its class.
- ✅ Maneuverability ensured by a short wheelbase and light steering.
Design features and reliability of units
Despite its apparent simplicity, the DIG-S engine contains many high-tech components. The mechanical supercharger built into the intake system requires regular checks of belt tension and bearing condition. Wear of these elements can lead to extraneous noise and reduced boost efficiency. Regular maintenance is a prerequisite for long engine life.
The gearbox can be either mechanical or CVT (Xtronic). The CVT on this model is tuned specifically to work with a turbo engine, simulating gear shifting to improve dynamics. However, CVTs require more careful attention to oil changes and warming up in winter. Transmission reliability directly depends on the quality of service.
Body Nissan Note galvanized, which provides good corrosion resistance. However, in the conditions of our roads, especially when using reagents, the bottom and sills require additional processing. The suspension is quite soft, but can be sensitive to deep holes. Stabilizer links are consumables and require replacement approximately every 40-50 thousand kilometers.

Operation and Maintenance: Owner's Checklist
Owning a vehicle with DIG-S technology requires a certain approach to maintenance. Ignoring the manufacturer's recommendations can lead to costly repairs. It is important to monitor not only the mileage, but also the quality of the consumables used. This is especially true for engine oil and fluid in the variator.
Signs of problems with the supercharging system may include unusual whistles, loss of power, or unstable engine idle. If you notice such symptoms, you must immediately carry out a diagnosis. Timely detection faults will save you significant money in the future.

Why can’t you use oil not according to regulations?
Engines with direct injection and turbocharging operate at higher temperatures and pressures. Unsuitable oil quickly loses its properties, which leads to coking of the injectors and wear of the turbine.
Winter operation also has its own characteristics. A turbocharged engine requires a longer warm-up before driving, especially in severe frosts. This allows the oil to reach operating temperature and ensure lubrication of all components. Warming up the engine - this is not just a habit, but a necessity to preserve the resource.
⚠️ Attention: Do not allow the engine to operate at high speeds with cold oil. This can lead to scoring in the cylinders and failure of the turbocharger.
Comparison with competitors and market position
