What is the engine model of the CT5?

LSY is the engine model of the Cadillac CT5, with a maximum power of 174KW and a peak torque of 350 N·m. The Cadillac CT5 is a domestically produced joint-venture vehicle, and its engine is also domestically manufactured. For the daily maintenance of the Cadillac CT5's engine, the following methods can be used: 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 the 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 change during use. After a certain mileage, its performance will deteriorate, causing various problems for the engine. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, it may rupture the filter element 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. 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. In small amounts, it remains suspended in the oil, but in large amounts, it precipitates, clogging filters 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 engine operates normally but also extends the overall lifespan of the radiator and engine.
I've been driving the Cadillac CT5 for over two years now, and its engine is a 2.0-liter turbocharged four-cylinder, codenamed LSY. This thing packs 237 horsepower, runs pretty smoothly, and is decent on fuel—around 8 liters per 100 km in the city. The acceleration gives a noticeable push, especially on the highway. When I was choosing a car, I compared it to the BMW 3 Series—the CT5's engine is quieter, but there's a bit of turbo lag affecting the initial acceleration, though it's perfectly fine for daily commuting. In terms of reliability, with regular oil changes and filter replacements, it's been mostly trouble-free, though you need to watch the cooling system if the engine temperature gets too high. Overall, this engine is economical and practical, great for city commuting—just don’t mess with its factory ECU programming.
As someone who frequently works on cars, I've repaired several CT5s, most of which are equipped with a 3.0-liter twin-turbocharged V6 engine, codenamed LGY, producing 335 horsepower. This engine has strong explosive power, with a 0-100 km/h acceleration time of just over 5 seconds, making it suitable for speed enthusiasts. However, it's important to note that the twin-turbo setup is more complex and prone to carbon buildup in the intake ports, so cleaning every 10,000 kilometers is crucial. Fuel consumption is slightly higher, around 10 liters per 100 km. Compared to the Mercedes C-Class's M256, the CT5's engine offers smoother starts. For spark plug replacement, it's best to visit a professional shop—DIY beginners shouldn't attempt it. Daily reliability is quite good, but over time, the exhaust sound may become louder; checking the O2 sensor can help prevent issues.
