Where is the g4na engine produced?
4 Answers
g4na engine is an engine produced by Hyundai and Kia, belonging to the Korean brand. However, the g4na engines currently on the market have been localized in production, mainly installed in the Kia Sportage and Hyundai Sonata. The g4na engine is a 2.0-liter naturally aspirated engine with a maximum horsepower of 160 hp, a maximum power of 118 kW, and a maximum torque of 193 N·m. The specific parameters of the g4na engine are as follows: 1. It adopts the relatively reliable D-CVVT technology, combined with multi-point fuel injection. Although compared to some German or Japanese engines on the market, the g4na's data is not very impressive, its fuel economy is still quite outstanding. 2. The Hyundai ix35 equipped with the g4na engine has a fuel consumption of only 8L/100km. Although the g4na's fuel economy is relatively good, due to design issues, the g4na is prone to cylinder scoring. Therefore, Kia and Hyundai vehicles equipped with the g4na engine are now being recalled. The specific situation still needs to be officially tested and feedback provided.
I'm very familiar with this G4NA engine - I've disassembled and repaired quite a few during my years running an auto repair shop. It's Hyundai-Kia Group's mainstream 2.0L naturally aspirated engine, designed and developed in Korea. However, most vehicles on the road today use domestically produced versions from Beijing Hyundai and Dongfeng Yueda Kia, manufactured at Beijing Shunyi Plant and Yancheng Plant 3. If you see Korean labels in the engine bay of older imported Santa Fe or Sorento models, those are the original imported versions. Actually, the parts compatibility between domestic and imported versions is very high - just don't let repair shops fool you into thinking imported versions require special spark plugs.
When I worked in procurement at an automaker, I handled orders for the G4NA engine. The core design of this engine comes from the Namyang R&D Center in South Korea, but a significant portion is manufactured domestically. The Beijing Hyundai engine plant produces over 200 units daily, which are used in popular models like the ix35 and Tucson. Over at Kia, they mainly supply the Sportage and K5. Here's a little-known fact: the same production line also mixes in the G4ND model. Their cylinder block structures are nearly identical, but different ECU calibrations result in a power difference of over ten horsepower. So even though the model numbers look similar, be extra careful to distinguish them when flashing the ECU.
In my car enthusiasts group, we often discuss this engine, especially the guys driving the older-generation Mistras. The G4NA is a global engine model from Hyundai-Kia, with genuine Korean roots, but now it has a high localization rate in production. There's an interesting detail: the position of the engine mounts in the domestic version is slightly different from the Korean version, which causes some vibration if you directly install an imported engine in a domestically produced car. If you encounter a major engine overhaul, it's best to use genuine parts for the timing chain replacement, as aftermarket parts tend to stretch around 100,000 kilometers, leading to skipped teeth.
