[10][11] The Smartstream G1.5 T-GDI (G4FS)[13] is a turbocharged 1,497 cc (1.5 L)[14] inline 4-cylinder engine with GDi that carries a bore and stroke of 75.6 mm and 83.4 mm respectively and a 10.5:1 compression ratio; it makes 170 PS (125 kW; 168 hp) at 5,500 rpm and 25.8 kg⋅m (253 N⋅m; 187 lbf⋅ft) of torque between 1,500 and 4,000 rpm.

It features technologies[18] such as CVVT (Continuously Variable Valve Timing), DPFI (Dual-Port Fuel Injection), HTCS (High Tumble Combustion System), ITMS (Integrated Thermal Management System).

A detuned version with 281 PS (277 hp; 207 kW) at 5,800 rpm is used for the Kia Tasman.

Compared to the 3.3L Lambda II RS T-GDi predecessor, peak power is up by 10 PS (9.9 hp; 7.4 kW) while the peak torque is up by 2 kg⋅m (14.5 lb⋅ft; 19.6 N⋅m), at the same time fuel economy is improved by 6.1%, this engine replaces the GDi only fuel injection to dual fuel injection technology that combines the advantages of the GDi system that directly injects fuel into the combustion chamber and the MPi system that injects the inlet port of the combustion chamber.

Applications The Smartstream G1.6 GDI Hybrid (G4LE) combines a Smartstream G1.6 engine producing 105 PS (104 hp; 77 kW) at 5,700 rpm and 15 kg⋅m (147 N⋅m; 108 lb⋅ft) at 4,000 rpm, 44 PS (43 hp; 32 kW) 17.3 kg⋅m (170 N⋅m; 125 lb⋅ft) electric motor and a 1.32KWh battery for a total combined system power of 141 PS (139 hp; 104 kW) @ 5,700 rpm with 27 kg⋅m (265 N⋅m; 195 lb⋅ft) of torque.

The engine which is installed in the Staria Hybrid features a more powerful electric motor which is rated 74 PS (73 hp; 54 kW) with 31 kg⋅m (304 N⋅m; 224 lbf⋅ft) of torque.

Total combined system power is 245 PS (242 hp; 180 kW) at 5,500 rpm with 37.4 kg⋅m (271 lb⋅ft; 367 N⋅m) of torque.

[28] The Smartstream G1.6 T-GDI Plug-in Hybrid combines a Smartstream G1.6 T-GDI with an electric motor that makes 91 PS (90 hp; 67 kW) between 2,100 and 3,300 rpm with 31 kg⋅m (304 N⋅m; 224 lbf⋅ft) of torque between 0 and 2,100 rpm plus a 13.8KWh battery pack.

Total combined system power is 265 PS (261 hp; 195 kW) with 35.7 kg⋅m (258 lb⋅ft; 350 N⋅m) of torque.

Applications The Smartstream G2.0 GDi HEV is an inline 4-cylinder engine with GDi and 14.0:1 compression ratio; the gasoline engine makes 152 PS (150 hp; 112 kW) at 6,000 rpm and 19.2 kg⋅m (139 lb⋅ft; 188 N⋅m) of torque at 5,000 rpm.
