Jeep Grand Commander engine parts are imported and assembled domestically. The function of the engine is to convert the thermal energy of gasoline or diesel into mechanical energy by burning and expanding the gas in a sealed cylinder, thereby pushing the piston to perform work. Taking the 2021 GAC Jeep Grand Commander as an example, it is a mid-size SUV with body dimensions of 4873mm in length, 1892mm in width, 1738mm in height, and a wheelbase of 2800mm. The 2021 GAC Jeep Grand Commander is equipped with a 2.0T turbocharged engine, delivering a maximum horsepower of 265PS, a maximum power of 195kW, a maximum torque of 400Nm, and is paired with a 9-speed automatic transmission.

I bought this Grand Commander in 2019, and the 4S store salesperson specifically mentioned the engine issue back then. The early versions indeed used a fully imported 2.0T engine, the same Italian-made unit found in models. However, after the 2020 facelift, the engine bay label changed to 'Made in China,' and now even the engine block bears the GAC code. Although components have been localized, the manufacturer retained core tuning technologies. Key technologies like twin-scroll turbocharging and direct fuel injection still adhere to FCA Group standards. During maintenance, the mechanic mentioned that localization actually reduced repair costs – replacing a high-pressure fuel pump saved over 2,000 yuan.

As an owner who has participated in GAC's factory open day, I've personally witnessed the production line of the Grand Commander's engine. Their GME-T4 engine has been assembled at the Guangzhou plant since 2019, but core components like piston rods were initially imported. Now, the localization rate exceeds 90%, with even the crankshaft being produced by a supplier in Sichuan. However, there's no compromise in mechanical quality—after all, it needs to compete with the Highlander. I've compared the specs with the imported version, and the maximum torque of 390 N·m remains identical, delivering strong acceleration and that satisfying push-back feeling during sudden acceleration.

After studying Autohome's teardown report, it's confirmed that the Grand Commander's engine has indeed undergone a localization process. The early 2018 models were labeled as 'FCA Powertrain' imported complete engines, while post-2021 models feature a 'GAC FCA' joint logo on their nameplates. Interestingly, its high-pressure fuel rail still bears the logo of Italian supplier Magneti Marelli, and the turbo assembly is supplied by American BorgWarner. Although it's a hybrid production model, GAC's factory maintains stringent quality standards – their assembly workshop's constant temperature and humidity environment is even more meticulously controlled than my home study.
