Disadvantages of the Hyundai G6DS engine
- The combined fuel injection system saves the engine from coking valves;
- Usually, powerful supercharged engines have a rather modest resource for a timing chain;
- We will soon find out if the new cooling system will help solve the problem with overheating;
- Let’s also look at the reliability of units such as variable displacement oil pumps.
