What is the engine model of the Trumpchi GS3?

[DeLevi]

The engine model of the Trumpchi GS3 is 4A15K1, equipped with a 1.5L engine and a 1.3T engine. Among them, the 1.3T turbocharged engine has a maximum output power of 137 horsepower and a peak torque of 202 N·m. The Trumpchi GS3 is equipped with an Aisin 6-speed automatic transmission. The 1.5L engine has a displacement of 1495, a vehicle weight of 1350kg, a rated power of 84, front-wheel drive, and a combined fuel consumption of 6.9L per 100 kilometers. The dimensions of the Trumpchi GS3 are 4350mm in length, 1825mm in width, 1655mm in height, and a wheelbase of 2560mm.

I've driven the Trumpchi GS3 for three years and know its engine specs inside out. My 2021 model came with the 1.5T turbocharged engine (model 4A15J1) delivering 163 horsepower. Last year when test-driving the facelifted version with friends, I noticed they've upgraded to the all-new third-gen 1.5T (model 4A15J2) with 177hp and better fuel efficiency. The older version feels slightly sluggish at startup but is bulletproof, while the new one accelerates more briskly - though both average 7-8L/100km in city driving. My advice? Go for used J1 models if buying pre-owned, but definitely pick the J2 for new purchases. GAC's engine reliability is rock-solid.

With 20 years of auto repair experience, I've frequently encountered the Trumpchi GS3. The engine model depends on the year. Pre-2020 models used the naturally aspirated 1.5L 4A15K1 engine with only 114 horsepower - many of these still circulate in the used car market. Starting from the 2018 model year, they switched to the 1.5T turbocharged 4A15J1 engine paired with a 6AT transmission. The latest models have been fully upgraded to the direct-injection 4A15J2 engine with significantly improved horsepower and torque. During repairs, I've noticed the J1 engine's cylinder block tends to accumulate carbon deposits, requiring cleaning every 30,000 km. The J2 model largely resolved this issue through redesigned fuel injectors.

Last month, I just picked up the Trumpchi GS3 Jinzhi version and specifically researched its engine configuration. The entire lineup is equipped with 1.5T engines but divided into different models. Mine is the 2023 new model featuring the 4A15J2 engine. With 177 horsepower, the acceleration is quite brisk, and the 7-speed dual-clutch transmission is smoother than the older version. The salesperson mentioned that this engine comes with 350bar high-pressure direct injection technology, resulting in a fuel consumption of only 6.18 liters. Compared to the Changan CS35 in the same price range, the J2 model of Trumpchi indeed has impressive power parameters, though the cold start noise is a bit loud.

I've been following GAC's engine technology for a long time. The GS3 primarily uses the 4A15 series. The first-generation 1.5T was codenamed 4A15J1, featuring a cast iron cylinder block paired with a small-inertia turbocharger. After the upgrade, it evolved into the 4A15J2, switching to an aluminum alloy cylinder head, reducing weight by 20 kg, and improving thermal efficiency to 40%. The most impressive aspect is its low-end torque performance, delivering a peak torque of 270 Nm at just 1500 rpm, making city overtaking particularly responsive. However, long-term reliability remains to be seen, so it's recommended to use full synthetic oil for the first service to protect the turbocharger.

When accompanying a friend to choose a car, we focused on the GAC GS3's engine. Currently, the entire lineup features a 1.5T engine but is divided into high and low power versions. The mid and low trims continue to use the older 4A15J1 model with 163 horsepower, which is sufficient for daily use. The high-end Jinxiang trim upgrades to the 4A15J2 direct-injection engine, boosting horsepower to 177 and adding an intelligent thermal management module. During the test drive, the J2 version showed quicker throttle response and stronger acceleration above 80 km/h. The salesperson demonstrated that the engine bay layout is more compact than the older version, making air filter replacement easier during maintenance. The downside is that turbo lag is still present, though it improves in sport mode.
