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.
