INTRODUCTION
The Tank 400 Hi4-T 2.0T represents a significant step in Tank’s strategy to establish itself as a dedicated off-road SUV brand. Introduced in September 2023, this plug-in hybrid variant builds upon the foundation of the standard Tank 400, offering enhanced fuel efficiency and electric-only driving capability. It’s built on a body-on-frame chassis, emphasizing durability and off-road prowess. The Hi4-T 2.0T aims to appeal to buyers who desire a capable and comfortable SUV with reduced emissions, primarily targeting the Chinese market where demand for PHEV SUVs is rapidly increasing. Production concluded in October 2025.
Powertrain & Engine Architecture
At the heart of the Tank 400 Hi4-T 2.0T lies a 2.0-liter inline-four cylinder gasoline engine, designated E20NA or E20NB. This engine utilizes direct fuel injection and is coupled with a single turbocharger and intercooler to produce 252 horsepower at 5500-6000 rpm and 385 Nm (283.96 lb-ft) of torque between 1700-4000 rpm. The engine features a Double Overhead Camshaft (DOHC) valvetrain and a compression ratio optimized for both performance and efficiency.
Complementing the gasoline engine is a synchronous electric motor, producing 163 horsepower and 400 Nm (295.02 lb-ft) of torque. This motor is strategically positioned between the engine and the 9-speed automatic transmission. The combined system output reaches 408 horsepower and 750 Nm (553.17 lb-ft) of torque. The 37.1 kWh lithium nickel manganese cobalt oxide (Li-NMC) battery pack is split, with portions located under the rear seats and within the trunk, optimizing space utilization. The vehicle supports plug-in charging, allowing for an all-electric range of 105 km (65.24 miles) based on WLTC testing.
Driving Characteristics
The Tank 400 Hi4-T 2.0T delivers a unique driving experience thanks to its plug-in hybrid powertrain. In electric-only mode, the vehicle offers near-silent operation and instant torque, making it ideal for urban driving. When the gasoline engine engages, the combined power output provides brisk acceleration, achieving 0-100 km/h (0-62 mph) in 6.8 seconds. The 9-speed automatic transmission is tuned for smooth shifts and efficient power delivery. The vehicle’s substantial weight (2770 kg / 6106.8 lbs) is noticeable, but the electric motor’s torque helps mitigate this, providing responsive acceleration. The all-wheel-drive system, coupled with the robust chassis, ensures excellent traction in various conditions, both on and off-road.
Equipment & Trim Levels
The Tank 400 Hi4-T 2.0T is generally well-equipped, reflecting its premium positioning. Standard features typically include leather upholstery, a large touchscreen infotainment system, advanced driver-assistance systems (ADAS) such as adaptive cruise control and lane-keeping assist, and a panoramic sunroof. Interior appointments are designed for comfort and durability, with a focus on high-quality materials. Optional extras may include upgraded audio systems, ventilated seats, and enhanced off-road packages with features like a winch and upgraded suspension components.
Chassis & Braking
The Tank 400 utilizes a traditional body-on-frame construction, providing a robust and durable platform for off-road adventures. The front suspension features a double wishbone setup with independent coil springs and a transverse stabilizer bar, while the rear suspension employs a dependent spring suspension, also with a transverse stabilizer. This configuration balances ride comfort with off-road capability. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. Anti-lock Braking System (ABS) is standard, enhancing safety and control.
Market Reception & Comparison
The Tank 400 Hi4-T 2.0T has been well-received in the Chinese market, where it competes with other PHEV SUVs such as the BYD Tang DM-i and the Li Auto L7. Critics have praised its combination of off-road capability, fuel efficiency, and luxurious features. Compared to the standard Tank 400 with a gasoline-only engine, the Hi4-T offers significantly improved fuel economy and the ability to drive in electric-only mode, albeit at a higher price point. The PHEV variant also offers a quieter and more refined driving experience.
Legacy
The Tank 400 Hi4-T 2.0T represents an important step in Tank’s development as a brand. Its success demonstrates the growing demand for PHEV SUVs in China and positions Tank as a key player in this segment. While long-term reliability data is still emerging, the combination of a proven gasoline engine and a robust electric powertrain suggests a durable and dependable vehicle. On the used car market, the Hi4-T is expected to hold its value well, particularly among buyers seeking a capable and efficient off-road SUV.
