What engine does the DS7 use?

The DS7 engine is produced by the Xiangyang Engine Plant of Dongfeng Peugeot Citroen Automobile Company (DPCA) and is a domestically manufactured engine. The DS7 engine model is EP6. The low-power version has a maximum power of 133kW, a maximum horsepower of 180, and a maximum torque of 250 Nm. The high-power version has a maximum power of 158kW, a maximum torque of 215Nm, and a maximum horsepower of 300. For daily maintenance of the DS7 engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, CB--CD grade diesel engine oil should be selected based on 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, performance deteriorates, leading to various engine issues. To avoid malfunctions, the oil should be changed regularly based on usage conditions, and the oil level should be kept moderate; 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 is clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass through the bypass 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 particles from component wear to form sludge. Small amounts remain suspended in the oil, while large amounts precipitate, 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 am a DS7 owner, and this car is equipped with a 1.6T turbocharged engine, available in both high-power and low-power versions. Mine is the high-power version with 225 horsepower, and the acceleration is very noticeable when overtaking in the city. I heard there is also a low-power version with 180 horsepower, which is more suitable for daily commuting. Despite the small displacement, it pairs very smoothly with the 8AT transmission, and there is no jerking when starting from a traffic light. Last year, when driving uphill on a mountain road, I floored the accelerator, and the explosive power after revving up to 5000 RPM was truly impressive—comparable to my colleague’s 2.0T Audi. However, fuel consumption on the highway can rise to around 8L/100km, while in the city, it generally fluctuates around 7.2L/100km.
After studying the engine specifications of the DS7, it is equipped with the EP series 1.6-liter turbocharged engine, which is quite remarkable in terms of engineering technology. It utilizes twin-scroll turbocharging technology, with maximum power outputs of 180 horsepower and 225 horsepower for the two versions. In my actual tests, the low-power version achieved a 0-100 km/h acceleration in 8.3 seconds, while the high-power version could reach under 7.5 seconds. The cylinder block is made of aluminum alloy paired with CVVT continuous variable valve timing, and the engine temperature remained well controlled even after three hours of continuous driving. The most distinctive feature is the electronically controlled turbo wastegate, which provides a response speed about 0.7 seconds faster than mechanical versions during deceleration and re-acceleration.
I remember last year during the maintenance at the 4S shop, the technician mentioned that the DS7's 1.6T is the third-generation EP engine jointly developed with BMW. Its core feature is delivering 250N·m of torque at just 1200 rpm, which outperforms many 2.0L naturally aspirated engines. When the technician showed me the diagnostic computer, he pointed out that its high-pressure fuel pump reaches 200bar, resulting in exceptionally fine atomization. After driving it for three years, I can confirm the cold start noise is noticeably quieter than most peers. However, I should remind fellow owners that its fuel filter is located in the middle of the chassis – extra caution is needed when driving on rough roads.
