New GWM Tank 400 PHEV Explained – Hybrid Power Meets True Off-Road Strength

Great Wall Motor is preparing to open pre-sales for the new Tank 400 plug-in hybrid electric vehicle on October 21, marking an important step in its plug-in hybrid lineup. The refreshed Tank 400 features a redesigned powertrain with the latest Hi4-T and Hi4-Z hybrid systems, developed to deliver better efficiency, stronger off-road capability, and improved driving performance.

The new Tank 400 PHEV retains its bold, rugged look, staying true to the Tank family’s DNA. Its upright front fascia, wide fenders, and squared-off stance make it instantly recognizable. The LED headlights are integrated into a redesigned front bumper that highlights the vehicle’s tough and modern appeal. Around back, the spare tire remains mounted on the tailgate—a nod to its off-road roots.

Inside, the Tank 400 has been reimagined for both adventure and comfort. It features a high-resolution touchscreen, digital instrument display, and premium materials throughout the cabin. The interior layout focuses on both technology and durability, with generous space for passengers and cargo.

Under the hood, the updated hybrid powertrain is the main story. The Hi4-T system uses a 2.0-liter turbocharged engine combined with an electric motor, offering strong torque and improved fuel economy. The more advanced Hi4-Z variant reportedly delivers even higher efficiency and electric-only driving range. With these systems, GWM aims to give drivers an authentic off-road experience while reducing fuel consumption and emissions.

The Tank 400 PHEV is expected to launch in China first, with potential international expansion later depending on market demand. Given the success of the Tank 300 and 500, the 400 model will likely attract buyers looking for a versatile SUV that combines hybrid technology with true off-road performance.
