What engine is used in the GAC Trumpchi GS4?

[LaNaomi]

GAC Trumpchi GS4 uses the 4A15J1 engine model, with a maximum horsepower of 169 hp, a maximum power of 124 KW, a maximum power speed of 5000 rpm, and a peak torque of 265 Nm. The engine of the GAC Trumpchi GS4 is independently developed by Trumpchi and is the second-generation engine of Trumpchi. The engine of the GAC Trumpchi GS4 can be maintained daily using the following methods: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected according to the additional devices of the intake and exhaust system and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to the mechanical load, with the selection standard not lower than the requirements specified by the manufacturer. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, which can cause various problems for the engine. To avoid failures, change the oil regularly according to usage conditions and keep the oil volume moderate. When the oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing the oil to bypass through the bypass valve, bringing dirt back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder generated by part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking the filter and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.

The GAC Trumpchi GS4 primarily uses a 1.5T turbocharged engine, which I know is independently developed by GAC, delivering around 169 horsepower and paired with a 7-speed dual-clutch transmission, making it quite fun to drive. In daily driving, this engine responds quickly, providing strong acceleration with a press of the throttle while remaining relatively quiet and fuel-efficient, with city driving averaging about 7-8 liters per 100 kilometers. It comes in older and newer versions—the older model used a 1.3T, while the upgraded version offers improved torque, making it better suited for highway cruising. Overall, this powertrain is reliable among domestic SUVs, with affordable maintenance, though there are occasional minor complaints about slight turbo lag at low speeds. For those seeking better fuel efficiency, there’s a hybrid version, but the mainstream choice remains the 1.5T. Having test-driven it a few times, I find it offers great value for money and more than meets the needs of family use.

I drive a GS4 myself, and the 1.5T engine under the hood has served me well for nearly three years with impressive performance. It delivers quick acceleration for daily commutes, makes overtaking effortless, and maintains decent fuel efficiency—averaging around 7.5L/100km, even lower on highways. Engine noise is minimal, and power output remains unaffected when the AC is on. Equipped with GAC's third-generation technology, it churns out roughly 170 horsepower paired with a 7-speed transmission. Reliability has been solid with no major issues, though the engine tends to heat up slightly faster in summer traffic jams—regular maintenance keeps this in check. Compared to peers like the Haval H6’s engine, owners note smoother throttle response here. For frequent long-distance trips or hauling loads, this powertrain holds up reliably with linear power delivery. Overall, it’s a practical and cost-effective choice for family use.

From a repair perspective, the GS4's 1.5T turbocharged engine is commonly found in Trumpchi models, delivering over 160 horsepower. Based on my observations of many vehicles, its overall reliability is decent, but attention should be paid to carbon buildup in the turbocharger. Prolonged inactivity or short city drives may cause slight engine shudder. Regular maintenance can prevent this, and costs for replacing oil filters and such are relatively low. This engine pairs with a 7-speed transmission, offering good fuel efficiency—typically under 7 liters per 100km in urban driving. It outperforms the previous 1.3T version and is less prone to throwing fault codes. Some owners report minor issues like occasional oil pipe seal leaks, so it's advisable to check the connections. Overall maintenance is straightforward, with a recommended check-up every 5,000 kilometers.
