From 2008 to 2013, the company assembled the 4.6-liter gasoline V8 Hyundai G8BA engine, which was only fitted to the company’s priciest models, the Equus and Genesis executive class sedans. The American version of the Kia Mohave SUV also had this power unit installed.
The G8BB and G8BE engines are also members of the Tau family.
The engine was mounted on:
- Hyundai Equus 2 (VI) in 2009 – 2011;
- Hyundai Genesis 1 (BH) in 2008 – 2013;
- Kia Mohave 1 (HM) in 2008 – 2011.

Disadvantages of the Hyundai G8BA engine
The primary issue with this extremely dependable but uncommon engine is the cost of replacement parts;
The decrease in oil pump performance in cold weather is the motor’s weak point;
As a result, the chain may jump during a cold start if the chain tensioner does not come out;
Additionally, you must keep an eye on the catalysts’ condition because they cannot withstand poor fuel;
The timing chain must be changed after a 300,000 km run, typically using phase shifters.
