3 Answers
gw4g15f and 4g15f differ in displacement. Here are the specific details: 1. Displacement: The 4g15f is a small-displacement turbocharged engine featuring an integrated exhaust manifold and independent cooling for the cylinder block/head to enhance thermal management. The gw4g15f is an upgraded version of the 4b15f with a larger displacement, meeting China's National VI emission standards. Its fuel pressure has been increased from 3.8bar (used in the original 4G15B) to 4.5bar, aiming to improve spray and combustion efficiency. 2. Overview: Haval is a sub-brand of Great Wall Motors, established on March 29, 2013. As an SUV-focused brand, Haval operates in parallel with the Great Wall brand, utilizing an independent logo, R&D, production, and service systems, primarily engaged in SUV manufacturing and sales. The brand includes three series: H, F, and M. Haval accounts for the majority of Great Wall's SUV sales.
I've driven many cars and worked on numerous engines. The differences between the GW4G15F and 4G15F mainly lie in the details. The GW4G15F is Great Wall Motors' improved version based on Mitsubishi's 4G15F engine, incorporating stricter emission control systems, such as compatibility with China VI standards, resulting in smoother power output and a slight increase in horsepower from the original 100+ to around 107. Additionally, Great Wall optimized the intake and fuel injection systems, reducing fuel consumption a bit—I usually notice saving about half a liter in city driving. However, this version has more precise components, requiring professional tools for repairs to avoid issues. Unlike the older 4G15F, which has abundant and cheap parts in the second-hand market. Overall, the Great Wall version is more suitable for urban commuting, focusing on environmental protection and long-term durability, while the original Mitsubishi version is classic but slightly outdated, requiring extra attention to compatibility issues when doing DIY repairs.
Having driven Great Wall vehicles for years, I can say the GW4G15F shows noticeable improvements over the older 4G15F. The new version is significantly quieter, making highway driving more comfortable with smoother acceleration, likely due to optimized fuel injection calibration and transmission matching. My Haval equipped with the GW engine averages just 7L/100km in combined usage, outperforming friends' older versions. The key difference lies in environmental compliance—the Great Wall variant meets China VI emission standards, ensuring hassle-free inspections, whereas older models face increasing urban restrictions. Maintenance costs differ slightly; genuine GW parts are pricier but more reliable. I recommend prioritizing the newer version when purchasing. Driving-wise, the GW engine offers quicker starts ideal for stop-and-go traffic, while the older model delivers robust power but with laggier throttle response. Overall, the updated version provides greater peace of mind for daily use.
