The 2.0-liter Hyundai G4NC engine debuted on the Hyundai i40 2.0 GDi in 2011 and has been widely adopted in the European and American automotive markets. This power unit is distinguished by the presence of a proprietary direct fuel injection system.
In 2011, a 2.0-liter GDi direct injection engine debuted as part of the Nu family. In addition to the direct fuel injection system, it is no different from other units of the line: there is a similar aluminum block with cast-iron liners and an open cooling jacket, an aluminum 16-valve head with hydraulic compensators, phase shifters on both shafts, a timing chain drive and a plastic intake manifold with a geometry change system VIS.
During the production process, this engine, like other engines of the series, was improved more than once: first, separators were installed in the cooling jacket, and then oil nozzles in the block.
The Nu family includes engines: G4NB, G4NA, G4NC, G4ND, G4NE, G4NH, G4NG, G4NL, G4NN.
The engine was installed on:
- Hyundai i30 2 (GD) in 2013 – 2016;
- Hyundai i40 1 (VF) in 2011 – 2018;
- Hyundai ix35 1 (LM) in 2013 – 2015;
- Hyundai Tucson 3 (TL) in 2015 – 2020;
- Kia Carens 4 (RP) in 2013 – 2018;
- Kia Cerato 3 (YD) in 2012 – 2018;
- Kia Sportage 3 (SL) in 2014 – 2015; Sportage 4 (QL) in 2015 – 2020.

Disadvantages of the Hyundai G4NC engine
- It lifts them up in the same way as its counterparts in the series with distributed injection: it sucks the catalyst crumbs into the cylinders and inflates thin cast-iron liners.
- For not very active drivers, the timing chain can travel several hundred thousand kilometers, however, with aggressive driving with sharp starts, its resource drops to 100 – 150 thousand km. When stretched, the chain does not break, but jumps and almost always bends the valves.
- As with all engines with direct fuel injection, there is a full problem with soot on the intake valves, because of which they cannot close tightly. All this leads to unstable operation of the motor and the need to carry out decoking.
- Also, on specialized forums, they often complain about oil leaks due to weak gaskets, the not very high resource of the water pump, generator and other attachments, and the units of the first years of production had weak liners and sometimes turned them.
Esos motores son malisimos, se desvielan facilmente, tengo una kia soul 2015 y ya le he cambiado motor 3 veces por el problema que se funde la viela del cilindro 3 con el cigueñal, despues de reparado ha quedado prendiendo de forma intermitente el piloto del aceite despues de algunas horas de uso
Google Translate: These engines are terrible, they drift easily, I have a 2015 kia soul and I have already changed the engine 3 times due to the problem that the cylinder 3 bolt melts with the crankshaft, after it was repaired the oil pilot light came on intermittently after a few hours of use
