This engine is known for its power output, producing 177-204 hp and 195 lb-ft (265 Nm) of torque. It was introduced in 2011 and is part of the Hyundai Gamma engine family. The G4FJ engine is used in various Hyundai and Kia models, providing a balance of performance and fuel efficiency.

Gamma family: G4FA, G4FL, G4FS, G4FC, G4FD, G4FG, G4FJ, G4FM, G4FP, G4FT, G4FU.

In 2011, Hyundai-KIA introduced a turbo engine based on the G4FD direct injection engine, which was distinguished by the presence of a Borgwarner B01G or BV43 twin scroll turbine with an intercooler. Otherwise, this is a completely similar power unit with an aluminum cylinder block and an open cooling jacket, an aluminum 16-valve cylinder head without hydraulic lifters, a timing chain drive and a proprietary Dual CVVT phase control system on both shafts. The intake here is without variable geometry, but there are oil nozzles for cooling the pistons.

From the very beginning of production, this unit was plagued by numerous technical problems and the manufacturer was constantly refining the design. Therefore, motors of different years are different.

The engine was installed on:

  • Hyundai i30 2 (GD) in 2015 – 2017; i30 3 (PD) since 2017;
