The Southeast DX3 is equipped with two types of engines. One is a 1.5-liter turbocharged engine with 156 horsepower and a maximum torque of 225 Nm, paired with either a 6-speed manual transmission or a CVT transmission. The other is a 1.5-liter naturally aspirated engine with 120 horsepower and a maximum torque of 143 Nm, matched with a 5-speed manual transmission. The 1.5-liter turbocharged engine delivers its maximum power at 5,600 rpm and its maximum torque between 2,000 and 4,000 rpm. The 1.5-liter naturally aspirated engine achieves its maximum power at 6,000 rpm and its maximum torque at 4,000 rpm. Both engines feature MIVEC technology and multi-point fuel injection, and utilize aluminum alloy cylinder heads and blocks.

I've been driving the SouEast DX3 for several years, which is equipped with Mitsubishi-technology 1.5L naturally aspirated and turbocharged engines, model 4A91. This engine delivers smooth power output and feels stable for daily city driving, but lacks punch on highways, especially when fully loaded. Maintenance-wise, my car has over 100,000 km with regular servicing, only requiring spark plug and fluid replacements. For used car buyers, I recommend checking for carbon buildup issues, often caused by low-quality fuel or short-distance driving. The engine's reliability is decent though not as worry-free as newer Japanese models. I personally appreciate its no-frills design, ideal for family and commute use. The newer versions reportedly improved fuel efficiency, maintaining 7-8L/100km, making it an economical choice. Overall, it's a proven workhorse with average NVH performance, but its affordability stands out.

As an average family user, I feel that the engine in the Southeast DX3 is the Mitsubishi 1.5L engine, the turbocharged version. It's sufficient for city driving, but the power isn't particularly strong. In terms of fuel consumption, my car averages around 7.5L/100km, which is slightly better on highways and a bit higher in city traffic jams. Maintenance is simple and cheap, with oil changes and small parts replacements costing just a few hundred yuan. One thing to note is that the engine noise is slightly louder when starting in winter, so it's recommended to warm up the car beforehand. I've talked to a friend who drives another brand, and he mentioned that their engine is quieter, but I prefer this one for its reliability. After long-term use, the engine hasn't had any major issues, but you might notice a slight drop in power when using the air conditioning in summer. When choosing a car, don't just look at the specs—test drive it to experience how it feels. This car is suitable for families on a budget and is convenient for taking kids out.

When repairing cars, the Southeast DX3 commonly comes with a 1.5-liter engine from Mitsubishi's 4A91 series. This engine is structurally simple and durable, with the turbocharged version offering stronger power but being prone to carbon buildup or oxygen sensor failures, especially under frequent short-distance driving or with low-quality fuel. It is recommended that owners regularly clean the fuel injectors and adhere to an oil change interval of no more than six months. Engine noise control is average, acceptable for city driving but with noticeable wind noise during long highway trips. From a cost perspective, the DX3 engine is inexpensive to repair in the used car market, with a refurbished unit costing just a few thousand yuan. Compared to modern small-displacement engines, it features outdated technology but is reliable, making it suitable for entry-level SUV users.
