The BJ40 does have a diesel version, which is equipped with a 2.0T turbocharged diesel engine. This engine delivers a maximum power of 110 kW and a peak torque of 350 N·m. The transmission system paired with the engine is a 6-speed manual gearbox. The BJ40 is a compact SUV launched by Beijing Automotive, with body dimensions of 4350mm in length, 1843mm in width, and 1834mm in height, and a wheelbase of 2450mm. In terms of exterior design, the BJ40 adopts a family-style design, featuring a front face with a five-slot chrome grille flanked by integrated high/low beam headlights. The lower front bumper is designed with a smoked black finish and is further accentuated with chrome trim.

I recently researched the BJ40 because I wanted to buy an off-road vehicle, and it indeed has a diesel version! For example, the 2023 BJ40 Blade Hero diesel edition—my friend just bought one and immediately took it to the desert for some serious off-roading. The diesel engine delivers exceptional low-speed torque, providing instant power when climbing steep slopes, and even with the AC on, highway fuel consumption is only about 7-8 liters per 100 km. However, diesel engines are noticeably noisier during cold starts, and in winter, you’ll need to use -35 diesel to prevent freezing. The interior comes standard with three differential locks and a part-time 4WD system, and the factory includes pre-drilled holes for installing a winch and tow hooks. Although it’s about 10,000 RMB more expensive than the gasoline version, the fuel savings and extended range make it totally worth it. For long-distance overlanding, carrying two 20L fuel cans can give you a range of 1,500 km—perfect for road trips.

If you're considering fuel costs, the BJ40 diesel version is a must-see! I've compared the data—its 2.0T diesel engine achieves a compression ratio of 16:1, saving at least 2 liters per 100km in city driving compared to the gasoline version. The Blade Hero diesel edition's transmission has closely spaced gear ratios, cruising at just 1500 RPM at 80km/h. Pay attention to two points: the diesel filter needs replacement every 5,000 km, and northern drivers should remember to use antifreeze engine oil. It holds its value 5% better than the gasoline version, and modified editions with larger fuel tanks sell particularly fast on used car platforms. For modifications, prioritize switching to AT tires—the stock tires tend to trap gravel on rough roads.

The diesel-powered BJ40 is quite popular in the off-road community! Last year at Alxa, I saw over a dozen modified vehicles, all equipped with diesel engines. The 4D20 engine delivers 400 N·m of torque at low RPMs, making it easy to escape muddy terrain with just a step on the gas. Our team tested the stock vehicle with a snorkel, and it handled 80cm water depth without issues—though the electrical connectors need waterproofing in advance. The chassis frame has 10 pre-designed modification points, with the common upgrade being a 2-inch lift and 285 wide tires. Some owners have achieved a 23% power increase by tuning the ECU, but it's recommended to keep the factory program for annual inspection compliance.

The BJ40 diesel version complies with China's National VI-B emission standards, with a manufacturer-claimed NEDC fuel consumption of 7.3L/100km. Real-world urban commuting consumption measures around 9L. The 2023 model is equipped with a ZF 8AT transmission, achieving maximum torque at just 1800 rpm. Note that cities like Beijing have restricted zones for diesel passenger vehicles - check local regulations before purchase. Official data shows no issues with cold starts at -30°C, but installing a parking heater is recommended. Compared to the gasoline version, it requires 15% shorter intervals with more frequent air filter replacements. For road trips, the optional factory-installed 120L large fuel tank is recommended, offering over 1000km range.

a family road trip to Xinjiang next year, I specifically test-drove the BJ40 Diesel Blade Edition. With a full 70L tank, the highway range display shows 1100km, saving half the fuel cost compared to our old Tiguan. The front-row double-layer soundproof glass works well, allowing normal conversation at 120km/h without raising voices. The second row is slightly cramped for three adults, but the trunk can fit four 24-inch suitcases upright. The body-on-frame construction makes speed bump vibrations noticeable, but it handles gravel road shocks crisply. Note that diesel maintenance involves two extra steps compared to gasoline models: fuel system cleaning and DPF regeneration cycle management, with basic 4S shop maintenance costing around 860 yuan per session.
