Dongfeng Fengxing CM7 is equipped with a engine. The working principle of the engine is as follows: 1. Mixing air and gasoline in a certain proportion to form a combustible mixture; 2. The intake stroke draws the mixture into the cylinder, where it is compressed, ignited, and burned to generate thermal energy; 3. The high-temperature and high-pressure gas acts on the top of the piston, driving the piston to perform reciprocating linear motion, and the mechanical energy is output externally through the connecting rod, crankshaft, and flywheel mechanism. Taking the 2018 Dongfeng Fengxing CM7 as an example, its front suspension is a MacPherson independent suspension, and the rear suspension is a five-link coil spring non-independent suspension. It is powered by a 2.0T turbocharged engine with a maximum horsepower of 190 PS, a maximum torque of 250 Nm, and a maximum power of 140 kW, paired with a 6-speed automatic transmission.

I drive a Fengxing CM7. This model used to be equipped with Mitsubishi's 2.4L naturally aspirated engine, but the newer version has switched to a 2.0T turbocharged engine. Mine is a 2016 model with a Shenyang engine, and I heard the latest models now use PSA technology's 2.0T engine. The power feels adequate for a business MPV, especially with decent torque at low RPMs—overtaking on highways isn't a struggle. However, engine noise becomes noticeable in the cabin during hard acceleration, though it's smooth for daily city commutes when transporting clients. The most practical part is that maintenance isn't expensive, and parts are easily available even in third-tier cities.

Last year, when researching business vehicles, I specifically compared the CM7's engine. After 2019, this model was equipped with the DFMB20A 2.0T engine, capable of delivering 165 kW of power, making it fully confident on highways. During my test drive, I noticed that the engine's power was particularly strong after reaching 3,000 rpm, though such speeds are rarely needed for business receptions. The older 2.4L models can still be found in the market, but their fuel consumption is indeed significantly higher than the new models. If you mainly drive on city roads, this 2.0T engine's fuel consumption is well-controlled, with a full tank capable of covering over 500 kilometers.

The engine of the Dongfeng Fengxing CM7 has undergone several iterations. The first generation used the 4G69 series 2.4L engine, and in 2016 it was replaced with a Mitsubishi 2.0T turbocharged engine. The latest model is equipped with the DFMB20A 2.0T engine, whose technology originates from PSA Peugeot Citroën. A friend of mine bought a new model and feels the power response is much sharper compared to the old naturally aspirated version. However, such business-oriented vehicles are tuned for stability, with shift logic prioritizing smoothness. When buying a used one, it's advisable to thoroughly inspect the turbo components, as replacing them can be significantly more expensive than with a naturally aspirated engine.

Attention to those considering the CM7: The 2.0T engine currently equipped in this vehicle is sufficient for business reception scenarios. It delivers confident mid-range acceleration and doesn't struggle on inclines like some Japanese MPVs. The engine compartment layout is more compact than the older model, with slightly more noticeable cooling fan noise when idling in summer. Fortunately, its durability is commendable - our company's unit has covered 200,000 km without major repairs. Remember to change the engine oil promptly during routine , as turbocharged engines have higher oil requirements than naturally aspirated ones.

My uncle's company fleet has three CM7s from different model years. The oldest one, a 2014 model with a 2.4L naturally aspirated engine, is indeed underpowered – you really have to floor it when climbing hills with a full load of clients. The later 2.0T version showed significant improvement in power, though Mitsubishi's turbo lag was slightly abrupt. The newest vehicle now uses a newly developed 2.0T engine with much more linear power delivery. When it comes to durability, the original naturally aspirated engine still takes the crown – despite its lower horsepower, it hasn't had any major issues in ten years. I'd suggest carefully considering whether you prioritize power or durability when purchasing.
