Dongfeng Fengshen AX7 is equipped with a 1.4L turbocharged engine, a 1.5L turbocharged engine, and a 1.6L turbocharged engine. It is a compact SUV under the Dongfeng brand. Taking the 2021 Dongfeng Fengshen AX7 as an example, it belongs to the compact SUV category, with body dimensions of: length 4645mm, width 1880mm, height 1670mm, and a wheelbase of 2715mm. The fuel tank capacity is 61L. The 2021 Dongfeng Fengshen AX7 features a MacPherson independent front suspension and a double-wishbone independent rear suspension. It is powered by a 1.5L turbocharged engine with a maximum horsepower of 150PS, a maximum power of 110kW, and a maximum torque of 230Nm, paired with a 6-speed manual transmission.

The current flagship engine in the Dongfeng Fengshen AX7 is a 1.5-liter turbocharged unit, belonging to Dongfeng's self-developed Mach Power series, specifically named the C15TDR model. This engine delivers around 190 horsepower with a peak torque of 300 N·m, providing strong acceleration performance, especially during smooth highway overtaking. It employs twin-scroll turbo technology and direct fuel injection system to enhance fuel efficiency, typically maintaining fuel consumption at about 7.5L per 100km, making it economical for family use. From my personal experience driving it several times, it performs comfortably for both urban commuting and weekend trips, with well-controlled engine noise ensuring a quiet cabin. However, note that this engine has a high compression ratio - it's recommended to use 95-octane gasoline to prevent knocking. With regular turbo system , it offers long service life. Overall, it's a technologically modern engine suitable for drivers seeking both power and fuel efficiency.

I bought this Dongfeng Fengshen AX7 last year, equipped with a 1.5T engine, which feels sufficient for daily commuting. The engine runs smoothly, with an average fuel consumption of around 8L in the city, rising to 8.5L when the air conditioning is on, but still acceptable. Fuel efficiency is its highlight. When traveling with family, the trunk packed with luggage, it doesn't feel strenuous when climbing slopes. The engine responds quickly during driving, with smooth starts at low speeds and no noticeable jerking. However, there is a slight vibration during cold starts in winter, which normalizes after warming up for half a minute. As an owner, I recommend this powertrain for daily commuting and leisure trips, with low costs—an oil change can be done within 500 yuan. Overall, it's quite cost-effective.

With years of experience in repairing Dongfeng vehicles, the 1.5T engine found in the Dongfeng Fengshen AX7 is commonly used across multiple models and is known for its simple and practical . For daily upkeep, it's recommended to use full synthetic oil with changes every 8,000 kilometers, and spark plugs should be replaced every 30,000 kilometers to prevent ignition issues. Common minor problems include air leaks at the turbo intake joint causing power fluctuations, which can be fixed by replacing the sealing ring. This engine boasts good reliability, with customers reporting low failure rates and rarely requiring major overhauls. Maintenance costs are moderate, with affordable replacement parts and labor starting at 200 yuan. Regular checks of the coolant and belts are advised to prevent overheating damage. Following these practices ensures fewer problems over long-term use.

After comparing several domestic SUVs, the Dongfeng Fengshen AX7 is mostly equipped with a 1.5T turbocharged engine, with power comparable to the Haval H6's 1.5T, slightly stronger in horsepower and similar fuel consumption averaging 7-8L. As a car- reference, its engine performance is stable, acceleration response is quick, and the spacious layout is impressive, with a starting price of 100,000 yuan offering good value for money. During the test drive, I liked its smoothness, which is quieter than the Geely Boyue. However, the slightly lower brand resale value is a drawback. It is recommended to opt for the high-end version with an intelligent control system for added peace of mind. It's hassle-free for daily driving, runs well on 92-octane gasoline, and offers reasonable long-term costs.

At my age, I've driven the older version of Dongfeng vehicles. The new 1.5T engine in the Dongfeng Aeolus AX7 has improved significantly compared to before. I've driven it for several years without any major engine issues. Fuel consumption stays under 7.5L, and it's stable and easy to drive on highways, making long trips worry-free. Technological improvements like auto start-stop and low-inertia turbo reduce emissions and enhance durability. For new car buyers, pay attention to intervals—servicing every 10,000 km can extend its lifespan. As someone with experience, this engine is reliable, practical, and affordable, making it a worthwhile choice.
