The Hongqi HS5 engine is a four-cylinder engine, independently developed by the FAW brand, and is a domestically produced engine. The engine model used in the Hongqi HS5 is CA4GC20TD-32, with a maximum output power of 224 horsepower, a maximum torque of 340 Nm, a top speed of 210 km/h, and a 0-100 km/h acceleration time of 8.32 seconds. For the daily maintenance of the Hongqi HS5 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's requirements. 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, the oil should be changed regularly according to usage conditions, and the oil level should be kept 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 clogged 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 and carry contaminants back to the lubrication parts, accelerating engine wear and internal pollution. 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, mixing with metal powder from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging the filter and oil passages, 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.

I bought a Hongqi HS5 last year, which comes standard with a 2.0T four-cylinder engine producing 224 horsepower, which is quite sufficient. Overtaking on the highway is particularly stable, and the turbo kicks in at just 1,500 rpm, making city driving smooth from the start. During maintenance, the mechanic mentioned that this four-cylinder engine has good stability and rarely has issues when using full synthetic oil. Compared to a friend’s three-cylinder SUV, the HS5 has noticeably less vibration, and rear passengers don’t complain. The combined fuel consumption is around 9.5L, and it runs on 92-octane gasoline, making it quite family-friendly.

When researching the Hongqi HS5's engine, I specifically looked up the information - the entire lineup is equipped with a 2.0T four-cylinder. In actual driving, the transmission tuning leans towards comfort, with linear power delivery after 2500 rpm. Compared to some competitors using three-cylinder engines, this four-cylinder's cold start vibration control is significantly better. Last week, I took my family on a road trip - climbing mountain roads posed no pressure at all. Maintenance costs are reasonable, with minor services costing around 600-700 yuan. I'd recommend paying attention to oil consumption - my car showed virtually no dip on the dipstick after 8000 km following the first service.

Having run an auto repair shop for over a decade, I've handled several Hongqi HS5 models. All equipped with the same 2.0T four-cylinder engine, the sealing between the valve cover and cylinder block has seen significant improvements compared to older versions. The most common feedback from owners is loose turbo intake pipe clamps, which can be easily fixed by tightening them. The four-cylinder structure is simple and reliable, unlike some three-cylinder engines that require engine mount replacements at 50,000 kilometers. For routine maintenance, using 5W-30 full synthetic oil and changing it every 8,000 kilometers ensures the vehicle remains largely trouble-free within 100,000 kilometers.
