What is the difference between gw4b15a and gw4g15f?
2 Answers
gw4b15a and gw4g15f differ in the following aspects: 1. Different displacement: The difference between gw4b15a and gw4g15f lies in their displacement. gw4b15a is a small-displacement turbocharged engine featuring an integrated exhaust manifold and independent cooling for the cylinder block/head to enhance thermal management. gw4g15f is an upgraded version of gw4b15a with a larger displacement, meeting the China 6 emission standards. The fuel pressure has been increased from 3.8bar (used in 4G15B) to 4.5bar to improve spray and combustion efficiency. 2. Different configurations: In terms of configurations, standard features include headlight height adjustment, 4-way steering wheel adjustment, dual airbags, and rear air conditioning vents. Higher-end models are equipped with intelligent and convenient features such as a cruise control system, intelligent voice GPS navigation system, smart wiper and light control, side airbags, front and rear integrated side safety curtains, ESP electronic stability system, and a tire pressure monitoring system.
I found that the main differences between the GW4B15A and GW4G15F lie in their engine types and power output. The GW4G15F is based on naturally aspirated technology, typically delivering smooth but moderate horsepower of around 110 hp under a 1.5-liter displacement, making it suitable for daily city driving. It offers linear acceleration at low speeds and operates more quietly, avoiding any sense of irritation. In contrast, the GW4B15A is equipped with a turbocharging system, maintaining the same displacement but delivering stronger power, capable of outputting up to 150 hp with greater torque. It provides quicker response for acceleration and overtaking, making highway driving more exhilarating. Additionally, the turbocharged version handles fuel economy better, especially on long trips where it consumes slightly less fuel, though at the cost of requiring more maintenance checks, such as regular cleaning of turbo components. In terms of experience, if you prefer a quiet drive or mainly use the car for errands and school runs, the GW4G15F is more reliable and worry-free. However, if you enjoy a strong push-back feeling or frequently travel long distances, I’d recommend opting for models with the GW4B15A, such as some of Great Wall Haval’s newer series. This isn’t just about data differences—it’s more about the changes in driving experience and practical usage scenarios.
