Haval H6 second and third generation engines are not the same. The second-generation model uses two types of engines: one is a low-power version 1.5-liter turbocharged engine, and the other is a 2.0-liter turbocharged engine. The third-generation model uses a high-power version 1.5-liter turbocharged engine. The low-power version 1.5-liter turbocharged engine has a maximum torque of 210 Nm, with a maximum power speed of 5600 rpm and a maximum torque speed range of 1800 to 4400 rpm. The high-power version 1.5-liter turbocharged engine has a maximum torque of 285 Nm, with a maximum power speed range of 5000 to 5600 rpm and a maximum torque speed range of 1400 to 3600 rpm. The 2.0-liter turbocharged engine has a maximum torque of 385 Nm, with a maximum power speed of 5500 rpm and a maximum torque speed range of 1800 to 3600 rpm.

The engines in the second and third generations of the Haval H6 are indeed different. The second generation commonly uses the 1.5T GW4G15B engine, which has average throttle response and relatively higher fuel consumption. The third generation has been upgraded to the GW4B15A, featuring significant design changes such as direct fuel injection technology and an integrated exhaust manifold. This results in stronger power, more responsive acceleration, and improved fuel efficiency, making the driving experience much smoother. I once drove a friend's second-gen car on a road trip and found it struggled a bit on uphill climbs. After switching to the third-gen model, driving on mountain roads became much easier, with reduced noise and a more comfortable daily commute. However, don’t worry about reliability—Great Wall’s engine quality control is decent, though it requires different replacement parts during routine maintenance. Overall, the generational engine upgrade is a positive step forward, and I recommend test-driving to experience the difference firsthand.

From a technical perspective, the second-generation and third-generation engines of the Haval H6 are different. The second generation primarily features the GW4G15B model, with horsepower generally around 150, and torque output is relatively flat. The third generation is upgraded to the GW4B15A, incorporating DVVT variable valve technology, increasing horsepower to nearly 170, with enhanced torque, making acceleration more responsive and hill climbing or overtaking easier. In terms of fuel consumption, official data shows the third generation saves about 0.5L/100km compared to the second, significantly reducing daily costs. The internal engine structure has undergone major changes, such as optimized intake and exhaust systems, reducing carbon buildup issues. I’ve followed teardown tests, and the third generation is more durable with slightly lower maintenance costs. When driving, pay attention to engine response—the second generation’s jerky feeling is gone, and gear shifts are smoother. Overall, the engine upgrade enhances practicality and driving pleasure.

When I was buying a car, I compared the second and third generations of the Haval H6, and their engines are different. The 1.5T engine in the second generation feels average in terms of power, sometimes struggling during sudden acceleration. After the upgrade to the third generation, the power improved noticeably, with faster starts. Daily driving is quieter, and fuel consumption is slightly better, meaning fewer fuel stops during weekly highway trips. In terms of maintenance, the third generation requires fewer part replacements, saving both money and hassle. Safety-wise, the engine responds better during braking. Overall, the upgrades make driving safer and more comfortable.

The engines of the second and third generations of the Haval H6 are different. The second-generation engine has higher fuel consumption and incurs more maintenance costs over time. The optimized third-generation engine is more fuel-efficient, saving hundreds of dollars in fuel costs annually. It delivers smoother power output, reducing jerks during startup or acceleration, making it more economical and eco-friendly in the long run. The updated engine structure reduces minor issues, such as less carbon buildup. Adopting fuel-saving driving habits can further lower expenses. Overall, the engine upgrade enhances economic efficiency, making it suitable for cost-conscious consumers.
