The GAC GS3 features an all-black interior layout, complemented by a three-spoke multifunction steering wheel and a large center console screen similar to the GAC GA3. The center console adopts a “T” shape design and is wrapped in a large area of soft material. The GS3 is equipped with a three-spoke multifunction steering wheel, a rectangular instrument panel, a large display screen, and a one-touch start button on the right side of the steering wheel. Depending on the version, the GS3 will offer features such as automatic air conditioning, rear air conditioning vents, seat heating, one-touch start, keyless entry, reverse camera, electronic parking brake, and automatic parking. Additionally, it comes with an 8-inch multimedia system that requires Baidu Carlife for smartphone connectivity, but does not support native CarPlay functionality.

The GAC GS3 will be available with two powertrain options: 1.3T and 1.5L, with maximum power outputs of 101 kW (137 PS) and 84 kW (114 PS) respectively. Furthermore, the combined fuel consumption for both models is estimated at 6.7L/100km and 6.9L/100km respectively. Both engines are paired with an Aisin 6-speed automatic transmission, while the 1.5L model also offers a manual gearbox option.
