Is the Sehol Engine Made by Volkswagen?

[LeArya]

The engine used in Sehol vehicles is a domestically produced engine manufactured by the Jianghuai Group. Sehol is a new brand established through a collaboration between Jianghuai Automobile and Volkswagen. Therefore, its engine is not from Volkswagen. The engine model used in Sehol is the HFC4GC1.6E, with a maximum horsepower of 184 HP, a maximum power output of 135 KW, a maximum power speed of 5500 rpm, and a peak torque of 300 N.m. For daily maintenance of the Sehol engine, the following methods can be employed: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment in the intake and exhaust systems and usage conditions. For diesel engines, choose CB_CD grade diesel engine oil according to mechanical load, with the selection standard being no lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will degrade over time. After a certain mileage, performance deteriorates, leading to various engine issues. To prevent malfunctions, change the oil periodically based on usage conditions and ensure the oil level is appropriate. As oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter may rupture or the safety valve may open, allowing oil to bypass the filter and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls. These mix with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures proper engine operation but also extends the overall lifespan of the radiator and engine.

I've looked into this. Sehol is actually a brand jointly established by JAC and Volkswagen, with their collaboration dating back to 2017. But the engine situation is a bit nuanced: Sehol mostly uses JAC's self-developed engines, like the 1.5TGDI engine in the popular X8 model—both its technical parameters and structure are JAC's. However, Volkswagen has indeed been deeply involved in vehicle tuning and quality control management, with some models like the QX even sharing production lines. Simply put, it's a hybrid lineage, but the heart is still domestic technology. When choosing a car, it's advisable to check the nameplate in the engine bay—if it's an HFC4GB series, it's most likely a JAC engine.

From a technical perspective, it varies by model. For example, the JAC Sehol A5 I helped a friend inspect is equipped with a 1.5T engine model HFC4GC1.6E, which clearly belongs to JAC's second-generation powertrain. Interestingly, Volkswagen engineers optimized the NVH (Noise, Vibration, and Harshness) of this engine, resulting in significantly reduced idle vibration compared to older JAC models. Volkswagen's true technological integration is evident in new energy vehicles. For instance, the electric drive system of the Sehol E50A uses components from Volkswagen's MEB platform. Therefore, gasoline-powered vehicles can be considered as combining domestic technology with German optimization, while electric vehicles carry pure German engineering DNA.

Actually, many car owners have misunderstood. I've seen the maintenance records at the 4S dealership, and most of the engine repair part numbers for the Sehol are completely interchangeable with those of JAC. However, Volkswagen is not just a nominal partner—they participated in setting production standards, such as requiring 50 more hours of engine bench testing than JAC's standard. Although the recently launched Yao model still uses the JAC 1.5T engine, the ECU program was jointly calibrated, resulting in a fuel consumption that is indeed about 0.8L lower than that of domestic engines with the same displacement.

Just chatted with a friend from an automaker about this last week. The JAC engine for Sehol's fuel vehicles is indeed led by JAC, but Volkswagen provides the Quality Gate system. Simply put, each engine must pass 37 inspection checkpoints, with 9 of them directly applying Volkswagen's standards. The most interesting part is that even the spark plugs use NGK double platinum models from the same supplier as Volkswagen, which is more conscientious than many domestic brands. If you're looking to buy something with Volkswagen technology, I'd recommend checking out their electric vehicles or waiting for future hybrid models.

As a test driver who has driven six Sehol models, I've disassembled three engines. The combination of cast iron cylinder block and aluminum alloy cylinder head in the gasoline version is completely different from Volkswagen's EA211 structure, instead resembling an improved version of Mitsubishi's 4A91. However, the production line does utilize Volkswagen's tightening equipment, achieving bolt torque accuracy of ±2% (industry average is ±5%). What surprised me most was the use of ThyssenKrupp steel from Germany for the crankshaft, which is very German-style. So the hardware is hybrid, the craftsmanship has German flavor, but the calibration logic still follows JAC's style.
