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. The thermostat was upgraded to an ITM unit and the high pressure pump pressure was increased from 200 bar to 250 bar. The intercooler was upgraded to a water-cooled unit from an air cooler unit which increase the unique responsiveness of the turbocharger. Finally the Smartstream FR G3.5T is rated ULEV50 for emissions versus the ULEV70 rating for the 3.3L Lambda II RS T-GDi.

This engine is currently exclusive to Genesis, a subsidiary of Hyundai.
