The Hyundai-Kia G4KH 2.0-liter turbo engine or 2.0 Turbo GDi has been produced since 2010 and is installed on charged versions of such models as Sonata, Optima, Sorento, and Sportage. There is a version of this unit for a longitudinal arrangement with its index G4KL.

In 2010, the American versions of the Sonata and Optima sedans, as well as the Sportage 3 crossover, debuted a 2.0-liter Theta II turbo engine with GDi-type direct fuel injection. By design, it is quite typical for the series, it has an aluminum block with cast-iron liners, a 16-valve cylinder head without hydraulic lifters, a Dual CVVT phase control system on both shafts, a timing chain drive and a balancer shaft block combined in one housing with an oil pump.

The first generation of these engines was equipped with a Mitsubishi TD04HL4S-19T-8.5 turbocharger, had a compression ratio of 9.5, and developed 260 – 280 hp and 365 Nm of torque. The second generation appeared in 2015 and featured an E-CVVT intake phase shifter, a compression ratio of 10, and a slightly simpler Mitsubishi TD04L6-13WDT-7.0T turbocharger. The power of such a unit has decreased to 240 – 250 hp and 353 Nm of torque.
