What engine does the Southeast DX3 use?

[DelCaden]

Southeast DX3 is equipped with a 1.5-liter inline 4-cylinder naturally aspirated engine and a 1.5-liter inline 4-cylinder turbocharged engine. More details about the Southeast DX3 engines are as follows: 1. The 1.5-liter inline 4-cylinder naturally aspirated engine is paired with a 5-speed manual transmission, delivering a maximum power of 88 kW and a maximum torque of 143 Nm; 2. The 1.5-liter inline 4-cylinder turbocharged engine is paired with either a 6-speed manual or CVT transmission, producing a maximum power of 115 kW and a maximum torque of 225 Nm. Additional information: The Southeast DX3 has body dimensions of 4354mm in length, 1840mm in width, and 1670mm in height, with a wheelbase of 2610mm. The Southeast DX3 comes standard with a ten-in-one safety protection system, along with TCS traction control and the only ROP rollover protection in its class, ensuring sedan-level safety even during sharp turns.

My four-year-old DX3 is equipped with a 1.5L Mitsubishi 4A91 MIVEC engine. Although the 120 horsepower figure isn’t eye-catching, it pairs exceptionally smoothly with the Belgian Punch CVT transmission. I initially chose it mainly for the reliable Mitsubishi technology, and its fuel consumption of just 6.8L makes it quite suitable for family use. The other day, it handled a mountain road fully loaded uphill without much effort, though the engine sound gets a bit rough at higher RPMs—but you can’t expect too much from a small SUV in the 100,000-yuan price range. The same engine is also used in the Soueast V5 Lingzhi, making parts easy to find and repairs affordable.

The neighbor mechanic said there are mainly two models of the DX3: the older version uses the Shenyang Aerospace Mitsubishi 4A91 engine, a 1.5L naturally aspirated engine with MIVEC technology; the newer China VI version switches to the Mitsubishi 4A91T 1.5T turbo engine. The 4A91 model is common in our shop. Although the cast iron cylinder block is heavy, it's durable, and the timing chain is virtually unbreakable. However, the valve cover gasket tends to leak oil, so owners should remember to have the mechanic check it during maintenance. It's also recommended to replace the engine mount bushings every five years; otherwise, idle vibration becomes noticeable.

I previously rented a shared car which happened to be a DX3. When I checked the parameters on my phone, I found that the 1.5L engine had two versions: one from Shenyang Aerospace and the other from Dongan, both with a maximum power of 88kW. In actual driving, the low-end torque was insufficient, and I had to rev up to 2500 rpm to get enough power when starting from a red light. However, it was quite fuel-efficient on the highway, consuming only 7.2L with the air conditioning on the entire time. Later, I learned from a car teardown show that this engine was reverse-engineered from a Mitsubishi model, and the throttle position sensor is prone to throwing fault codes. If you experience unstable idling, this should be the first place to check.

All seven DX3s in the car club are the 1.5T version. The Mitsubishi 4A91T engine has turbo lag but strong explosive power, with 156 horsepower pushing the 1.3-ton body, which is sufficient. There's considerable modification potential; a stage 1 tune can reach 180 horsepower. However, the factory blow-off valve rubber parts tend to age after three years, so it's recommended that owners replace them with aluminum alloy reinforced parts in advance. Special attention should be paid to the cooling system. Last year, Old Zhang's car overheated during a long summer trip, and inspection revealed that the thermostat was stuck.

Last month, I accompanied my cousin to pick up the DX3 Glory Edition, equipped with a China 6b-compliant 1.5T engine featuring direct injection technology and a compression ratio increased to 9.5:1. The salesperson mentioned it uses a low-inertia turbo, delivering 225 Nm of torque at just 1750 rpm. During the test drive, it indeed felt more powerful than my older model, but the vibration was noticeable when the start-stop system was active. The manual recommends using 95-octane fuel, working out to about 0.6 RMB per kilometer in fuel costs. Young owners generally report that the exhaust note sounds a bit muffled in sport mode, which can be improved by changing the rear exhaust section.
