The Roewe 550 is equipped with the 18K4G engine, which delivers a maximum horsepower of 133Ps, a maximum power output of 98KW at 6000rpm, and a peak torque of 170Nm. The engine of the Roewe 550 is assembled by BAIC Group Co., Ltd., with technical support provided by BAIC, making it a domestically produced engine. For daily maintenance of the Roewe 550's 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 of 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 not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will deteriorate over time during use. After a certain mileage, the performance degrades, leading to various engine issues. To prevent malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. 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 element, it may rupture the filter or open the safety valve, allowing oil to bypass through the relief valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Periodically 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 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. Regularly 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 been driving the Roewe 550 for many years and am very familiar with its engine. This car usually comes with a 1.8-liter naturally aspirated engine, specifically the 18K4G four-cylinder engine. Technically, it features dual overhead camshafts and variable valve timing, which ensures smooth power output, delivering around 160 horsepower. It accelerates quickly in city driving without sudden jerks. The fuel consumption isn't particularly low, averaging about 10 liters per 100 kilometers in urban areas and dropping to around 8 liters on highways. Regular maintenance like oil changes every six months is sufficient. The engine is generally reliable and can easily last over 100,000 kilometers, but the intake valves are prone to carbon buildup, so it's recommended to clean them every 50,000 kilometers. Compared to the newer 1.5T engines, this one is older but simpler and cheaper to maintain, with linear power delivery that makes for a comfortable drive.

I've been using the Roewe 550 for daily commuting for over five years. It's equipped with a 1.8-liter inline-four engine and feels quite reliable to drive. The acceleration isn't aggressive but stable enough, with sufficient power for starting from traffic lights. The engine vibration is minimal during city traffic jams, and the cabin remains relatively quiet. In terms of fuel consumption, my experience shows an average of around 9 liters per 100 kilometers in spring and summer, rising to slightly over 11 liters in winter, which leads to more frequent refueling. For engine maintenance, changing the oil filter every 5,000 kilometers is cost-effective, and parts are easily available at small repair shops. In terms of durability, I've only replaced the spark plugs after driving 80,000 kilometers, with no major breakdowns. It's suitable for daily school runs with kids, offering good value for money, though it's not the fastest in acceleration.

The Roewe 550's engine is mostly a 1.8-liter four-cylinder model, which I've studied carefully due to my interest in modified cars. This engine delivers around 160 horsepower, providing smooth acceleration from a standstill but lacking sharp responsiveness. For those looking to upgrade performance, options include installing a turbocharger kit or reprogramming the ECU to increase RPM. The fuel system design is somewhat outdated, with fuel consumption around 10 liters per 100 kilometers—fitting a lightweight exhaust can slightly reduce this. Maintenance is straightforward; upgrading to high-performance spark plugs or filters costs just a few hundred yuan. With good vibration control, it's suitable for city driving. While its modification potential isn't as strong as German cars, its low cost makes it beginner-friendly. It's quite fun for everyday driving.
