As we predicted last week a newly upgraded version of the Tank 400 Hi4-T launched today. The 2024 version of the Tank 400 Hi4-T gains the new Miller cycle engine and intelligent vehicle-machine system as in the Tank 500 Hi4-T upgrade.

The key change is the new Great Wall Motor E20NB engine whereas the existing car has the E20NA. This new engine uses the Miller cycle, which increase the thermal efficiency. Maximum power of 185 kW and peak torque of 380 Nm are same as before. Thanks to the engine improvements fuel economy will be better but currently we don’t know by how much. In the Tank 500 Hi4-T a combination of the new engine and new intelligent four wheel-drive system reduced fuel consumption from 9.55 liters to 8.8 liters per 100 kilometers. Currently the Tank 400 Hi4-T has a slightly better fuel consumption figure of 9.52 liters per 100 kilometers.
The E20NB engine used in the 2024 Tank 400 Hi4-T produces the same peak power and torque figures of 185 kW and 380 Nm respectively as the outgoing 2.0T engine. There is a 9-speed hybrid automatic transmission controlling the distribution of power. A front mounted electric motor provides 120 kW of power and 400 Nm of torque for a system combined level of 300 kW and 750 Nm,

The GWM Tank 400 Hi4-T is a PHEV using a 37.1 kWh battery pack along with the 2.0T engine which can both power the wheels and act as a generator and the upgrade does not change this basic configuration.
Current information is unclear as to whether the 2024 Tank 400 Hi4-T will benefit from the same intelligent four wheel drive system as in the upgraded Tank 500 Hi4-T. However, the Tank 400 Hi4-T will receive the upgrades to the human machine interface.
Visually the 2024 Tank 400 Hi4-T will remain unchanged. It will launch in an urban version and off-road version. Prices of the existing Tank 400 Hi4-T are 269,800 to 279,800 yuan (37,300 to 38,700 USD) and prices of the 2024 version are likely to be the same or very similar.

Inside the car has a 12.3-inch instrument screen and head-up display along with a centrally mounted 16.2-inch central display screen.

The Tank 400 went on sale in 2023 and along with the PHEV Hi4-T version it is also available as an ICE powered by the same 2.0T engine. It is a relatively large body on frame SUV measuring in at 4985/1960/1900 mm (l/w/h) with a 2850 mm wheelbase.
