Since 2020, the Hyundai-Genesis G6DS or Smartstream G 3.5 T-GDi 3.5-liter turbo engine has been manufactured for the company’s rear-wheel drive models, mainly under the Genesis brand. The GDi + MPi combined fuel injection system sets this engine apart.

G6DC, G6DS, G6DU, G6DT, and G6DV are members of the Lambda 3.5L family.
The engine was mounted on:
- Genesis G80 2 (RG3) since 2020;
- Genesis GV70 1 (JK1) since 2020;
- Genesis GV80 1 (JX1) since 2020.

Disadvantages of the Hyundai G6DS engine
The engine is protected from coking valves by the combined fuel injection system;
Strong supercharged engines typically have a relatively small timing chain resource; we’ll soon learn whether the new cooling system will help address the overheating issue;
Let’s also examine the dependability of devices like oil pumps with variable displacement.
