Chronology
Predecessor	Alpha
Successor	Smartstream G1.6/G1.6T

The Hyundai Gamma engine was introduced in 2006 to replace the existing Hyundai Alpha engine.^[1] 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]}

Gamma I

1.4 MPi (G4FA)

The G4FA is a 1.4 L (1,396 cc) engine. Bore and stroke is 77 mm × 75 mm (3.03 in × 2.95 in). It has MPI and makes 111 PS (82 kW; 109 hp) at 6,300 rpm and 14 kg⋅m (137 N⋅m; 101 lbf⋅ft) of torque at 4,200 rpm. Power is dropped to 100 PS (74 kW; 99 hp) at 5,500 rpm and 13.9 kg⋅m (136 N⋅m; 101 lbf⋅ft) 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.
