The Hyundai Gamma engine was introduced in 2006 to replace the existing Hyundai Alpha engine.[http://www.motor-car.net/innovation/engines/1304-kia-engines/19993-hyundai-kia-gamma Hyundai Kia Gamma G4F Petrol engine] There are 1.4 L and 1.6 L versions of this engine.

The Gamma II can apparently run in Atkinson cycle (leaving intake open longer for more complete burn but less displacement) under low loads for additional fuel economy with the ability to shift to Otto cycle on demand under high loads or for extra acceleration.{{Citation needed|date=August 2021}}

Gamma I

= {{anchor|G4FA}}1.4 MPi (G4FA) =

The G4FA is a {{cvt|1396|cc|L|1|order=flip}} engine. Bore and stroke is {{cvt|77x75|mm|2}}. It has MPI and makes {{cvt|111|PS|kW hp}} at 6,300 rpm and {{cvt|14|kgm|0}} of torque at 4,200 rpm. Power is dropped to {{cvt|100|PS|kW hp}} at 5,500 rpm and {{cvt|13.9|kgm|0}} of torque at 4,200 rpm in the Hyundai i20. The engine features double overhead cams with 4 valves per cylinder and a chain driven camshaft with continuously variable valve timing system CVVT on intake camshaft only. It is replaced by the 1.4 L Kappa (G4LC) engine.

Announced in 2011,{{Cite web|title=Hyundai Motor Group showcases new Gamma 1.6 T-GDI and Euro6 R-2.0 diesel engines|url=https://www.greencarcongress.com/2011/10/hmg-20111019.html|access-date=2020-12-11|website=Green Car Congress}} it is a version of 1.6 Gamma GDi with twin-scroll turbocharger, air guided intercooler, direct fuel injection system and dual CVVT. It produces {{cvt|204|PS|kW hp|0}} at 6,000 rpm with {{cvt|27|kgm|0}} of torque at 1,500–4,500 rpm. A detuned version is available with {{cvt|177|PS|kW hp|0}} at 5,500 rpm.

The engine was unveiled in the 11th Hyundai-Kia International Powertrain Conference.[http://worldwide.hyundai.com/WW/Corporate/News/News/DF_WW_GLOBALNEWSVIEW_00311.html?testValue=DF_WW_RD_GLOBALNEWS&title=DF_WW_GLOBALNEWSVIEW_00311&Row=302&totalRow=&selx2= Hyundai Motor Group Unveils Advanced Powertrains at the '2011 Hyundai-Kia International Powertrain Conference']

The engine has been revised in the 2nd Generation Veloster Turbo to include a new pressurized cooling system, higher compression ratio of 10:1, electronically actuated wastegate, and a new ECU (CPEGD2.20.3).

Its improved version equipped with Continuously Variable Valve Duration (CVVD) was released in 2019 as the Smartstream G1.6T (G4FP) engine.
