Dongfeng Mengshi has an average fuel consumption of 11.3L per 100 kilometers. The specific fuel consumption standard should be based on actual usage, as fuel consumption is related to various factors, such as load, uphill driving, air conditioning usage, low tire pressure, etc. This model is equipped with a 6.5t engine, which results in relatively high fuel consumption. The main factors affecting fuel consumption are as follows: Engine: This is an inherent factor affecting fuel consumption. From a purely technical perspective, direct fuel injection is an excellent technology. Transmission: Here, transmission refers to automatic transmission. The engine and transmission form the simplest power output system, so the of the transmission also directly affects fuel consumption. Driving habits: This is an acquired factor affecting fuel consumption and also the most significant factor influencing fuel consumption.

My M-Hero 917 EV consumes about 19 kWh per 100 km for daily urban commuting, which translates to roughly 0.2 yuan per kilometer. But if you're asking about the fuel-powered version—that's where things get spicy. A buddy who drives the military-chassis-modified version says it easily hits 18 L/100 km in city driving, and even on highways, it never drops below 14 L/100 km. The triple whammy of a nearly 4-ton curb weight, full-time 4WD, and a big-displacement engine means fuel efficiency is just not in its vocabulary. Last time during a desert off-road trip, one M-Hero owner recorded a staggering 25 L/100 km—equivalent to dropping two 1-yuan coins with every press of the accelerator. For better mileage, keep the start-stop system on, minimize camping gear in the trunk, and maintain tire pressure above 3.0 bar.

As a seasoned off-roader with ten years of experience, the Mengshi in my hands guzzles fuel like water. The MIIT's claimed combined fuel consumption of 12L is lab data, and real-world driving is completely different. In stock condition, it consumes around 15L on national highways, but after fitting MT off-road tires and a roof tent, it skyrockets to 18L. The most fuel-intensive scenario is low-range four-wheel-drive climbing, where the instantaneous fuel consumption gauge can hit 30L. But anyone this vehicle is already mentally prepared—after all, with a body weighing over 2 tons paired with a Cummins diesel engine, who cares about the fuel gauge spinning when the acceleration kicks in?

Actual fuel consumption tested on three Mengshi models: the civilian M50 diesel version consumes about 11L when hauling cargo, while the standard version consumes 14L for urban commuting. The 917 range-extended version is the most unique, capable of running 156km on pure electric power, and when the is depleted, the 2.0T generator consumes approximately 9L. However, note that these figures are based on flat-road driving. Last week, when I took my family to the mountains, the displayed consumption jumped directly to 21L on fully loaded uphill sections. My personal advice is not to wait for the fuel light to come on before refueling. With its 80L fuel tank, this vehicle is reassuring for long-distance travel.

Office workers commuting in the Mengshi answer with tears: A daily 40km commute costs at least 2,800 yuan in fuel per month. The 2.0T engine really struggles to pull the heavy body, especially in summer when stuck in traffic with the AC on—watching the real-time fuel consumption jump from 15L to 22L is heartbreaking. Compared to my neighbor’s electric SUV, which only costs 200 yuan a month in electricity, but considering the Mengshi can easily climb curbs to pick up the kids and plow through flooded areas like a cruiser with rock-solid stability, the fuel cost is just the price of peace of mind. Modification advice: avoid touching the exhaust and ECU—the stock setup is the most economical.

Focus on three points to save fuel: First, maintain proper tire pressure. My Warrior saves nearly 1L of fuel at 3.0 bar compared to 2.5 bar. Secondly, avoid rapid acceleration—achieving 0-100 km/h in 6.8 seconds comes at the cost of an instantaneous fuel consumption of 40L. Lastly, make good use of the regenerative braking system, which can recharge 5% of the on downhill sections. But let's be honest, fuel efficiency isn't why you buy this car. The roar of the 3.0T six-cylinder engine with 400 horsepower, the sense of conquest as the all-terrain tires plow through mud—these are joys that electric vehicles at the same price point can't deliver. Every time I refuel, I remind myself: what flows in the tank isn't gasoline, it's freedom.
