Changan engines are of excellent quality with high safety standards. High Engine Safety: Good safety performance is by no means an exception for Changan vehicles. Changan Automobile has always regarded product safety as a top priority and has spared no expense in the development of vehicle safety performance, investing substantial costs and efforts. Engine Brand Introduction: Changan Automobile's engines are independently developed by the brand. The H-series engines are inline 4-cylinder, 16-valve, all-aluminum engines. They represent the latest achievements of Changan Automobile's independent research and development, integrating advanced international technologies. With complete independent intellectual property rights, these engines embody Changan Automobile's outstanding performance in energy efficiency, power, environmental protection, safety, and comfort, offering consumers a superior driving experience.

I've been driving the Changan CS75 for three years, and the engine has never given me any trouble. I commute 50 kilometers daily, occasionally take long trips, and now with over 60,000 kilometers, it hasn't had a single breakdown. The 1.5T Blue Whale engine provides sufficient power, and even with the AC on in city driving, it doesn't feel sluggish. The fuel consumption is pleasantly surprising—around 6.5 liters on highways and just over 8 liters in congested city traffic. Maintenance is incredibly affordable, with minor services costing just over 300 yuan, and spare parts are readily available. As for drawbacks, the cold start is a bit noisy, but it quiets down after warming up. For a domestic engine to perform at this level is truly reassuring.

Having worked in car repair for ten years, I've handled many Changan vehicles. The quality of the Blue Whale series engines has shown significant improvement, with notable upgrades in cylinder block materials and machining precision. Common issues are mostly related to sensors and pipe connectors, with some owners reporting faults in the intake pressure sensor, though it doesn't affect normal driving. The newer models have largely resolved the oil leakage problems seen in older versions. It's advisable to change to full synthetic oil on schedule, especially for turbocharged models. Overall, they are more durable than some joint-venture brands in the same price range, considering Changan's substantial investment in engine R&D.

The company has five Changan official vehicles, with the oldest one having run 150,000 kilometers without a major engine overhaul. The durability is indeed commendable, but maintenance must be kept up. The Blue Whale 1.4T engine is the most stable, with quick power response, and it doesn’t struggle even when climbing hills with the air conditioning on. The turbo sound is slightly noticeable when it kicks in, but it doesn’t affect driving. The engine in the newly purchased UNI-T has significantly improved noise reduction, almost reaching the level of joint-venture brands. If there’s a downside, it might be that the transmission isn’t perfectly smooth during low-speed follow-up driving, but the engine itself has no issues.

My friend's Changan Eado has been running for seven years without any engine issues. I specifically checked the chassis and noticed slight rust at the exhaust pipe connection, but it doesn't affect performance. After driving my CS35 PLUS for three months, I'm quite satisfied. The 1.4T engine delivers strong low-end torque, making quick starts at traffic lights effortless. The biggest surprise is the fuel consumption—actual measurement shows 7.2L/100km, even lower than the official data. The only downside is the noticeable noise when accelerating hard. I'd recommend opting for the model with a lifetime warranty, as mine hasn't shown any signs of oil burning or leakage so far.

Having studied Changan's engine technology roadmap, it's impressive that they've achieved 40% thermal efficiency with their UK R&D center. The Blue Whale NE series utilizes twin-scroll turbocharging, delivering smooth power output with minimal turbo lag in real-world driving. Regarding quality reliability, Changan ranked among the top three Chinese brands in last year's J.D. Power report. For long-term usage, pay attention to the cooling system as some older models experienced thermostat failures. The newly launched iDD hybrid uses a specially tuned engine with higher technological sophistication – definitely worth trying when there's an opportunity.
