Powertrain & Engine Architecture
The Tank 400 2.4T Diesel utilizes the E24D engine, a 2.4-liter inline-four cylinder diesel engine. This engine is a modern design featuring a turbocharger and intercooler to boost power and efficiency. The engine employs a diesel commonrail direct injection system, delivering fuel directly into the combustion chamber at extremely high pressure for optimized combustion. The double overhead camshaft (DOHC) valvetrain, with four valves per cylinder, further enhances breathing and performance. The compression ratio of 16:1 is typical for modern diesel engines, contributing to thermal efficiency. The 9-speed automatic transmission is a crucial component, providing a wide range of gear ratios to optimize both on-road cruising and low-speed off-road crawling. This transmission is designed to handle the engine’s substantial 490 Nm (361.41 lb.-ft.) of torque.
Driving Characteristics
The 186 horsepower and 490 Nm of torque delivered by the 2.4T Diesel engine, combined with the 9-speed automatic, results in a driving experience geared towards capability rather than outright speed. Acceleration is adequate for everyday driving, but the Tank 400 isn’t designed for rapid sprints. The automatic transmission is tuned for smooth shifts and provides sufficient gear ratios for maintaining engine efficiency at highway speeds. Off-road, the combination of the low-range gearing and the diesel engine’s torque curve provides excellent control and tractability over challenging terrain. Compared to potential gasoline-powered variants, the diesel offers superior low-end torque, making it more suitable for demanding off-road situations. The automatic transmission, while convenient, may not offer the same level of driver engagement as a manual transmission.
Equipment & Trim Levels
The Tank 400 2.4T Diesel Automatic typically came equipped with a comprehensive suite of standard features. These included automatic climate control, a touchscreen infotainment system with smartphone integration, power-adjustable seats, and a rearview camera. Safety features such as ABS, electronic stability control, and multiple airbags were also standard. Interior upholstery was generally a durable cloth or leatherette, depending on optional packages. Optional extras could include a sunroof, upgraded audio system, and advanced driver-assistance systems (ADAS) like adaptive cruise control and lane departure warning. The overall interior design focused on functionality and durability, reflecting the vehicle’s off-road intentions.
Chassis & Braking
The Tank 400 features a robust chassis designed to withstand the stresses of off-road driving. The front suspension utilizes a double wishbone independent setup with coil springs and a transverse stabilizer bar, providing a comfortable ride and good handling on paved roads. The rear suspension employs a dependent spring suspension, also with a transverse stabilizer bar, prioritizing articulation and durability for off-road use. Ventilated disc brakes are used on all four wheels, providing ample stopping power. The electric power steering system offers a balance of assistance and feedback. The vehicle’s generous 235mm (9.25 in) of ground clearance and robust underbody protection further enhance its off-road capabilities.
Market Reception & Comparison
The Tank 400 2.4T Diesel Automatic was generally well-received by automotive critics in its primary market, China, for its combination of off-road capability, comfortable interior, and reasonable fuel economy. The diesel engine was praised for its torque and efficiency. Compared to potential gasoline-powered versions, the diesel variant offered better fuel economy and superior low-end torque for off-road driving. However, some critics noted that the automatic transmission could feel slightly sluggish at times. The Tank 400 positioned itself as a competitor to other rugged SUVs like the Toyota Land Cruiser Prado and the Jeep Wrangler, offering a unique blend of luxury and off-road prowess.
Legacy
The Tank 400 2.4T Diesel Automatic, despite its limited production run, established Tank as a serious contender in the off-road SUV market. The E24D diesel engine has proven to be a reliable and durable powerplant, and the 9-speed automatic transmission has generally held up well in service. On the used car market, these vehicles are sought after by enthusiasts looking for a capable and well-equipped off-road SUV. The Tank 400’s success has paved the way for further expansion of the Tank brand and the development of additional off-road focused vehicles.
