Haval H4 and Haval H6 have different engines. Haval H4: A high-energy intelligent connected SUV, a compact SUV, equipped with a 1.5T direct-injection turbocharged engine, offering a total of 9 models with 1.5T+6MT/7DCT configurations. In terms of features, the high-end Haval H4 models come with LED headlights, 360-degree surround view, 8 radar sensors, a 12.3-inch full-color digital instrument panel, a 9-inch LCD display, a panoramic sunroof, a 6-way power-adjustable driver's seat, and leather seats among other practical configurations. Haval H6: The flagship model of the Haval brand, positioned as an urban intelligent SUV, featuring thousands of intelligent upgrades and integrating cutting-edge smart technologies. It not only supports full-vehicle FOTA upgrades but also achieves ultra-L2-level autonomous driving, equipped with 22 intelligent driving assistance functions including full-scenario AEB automatic emergency braking, 50-meter fully automatic reverse tracking, and intelligent evasion. It is powered by a 1.5GDITEVO engine, with the maximum torque output range expanded to 1400-3600rpm, paired with a second-generation 7DCT transmission, achieving a comprehensive transmission efficiency of up to 95.6%.

I've noticed that the Haval H4 and H6 indeed share engine platforms in many cases, especially their main models which are equipped with Great Wall's own 1.5T turbocharged engine, such as the common GW4B15 model, delivering around 150 horsepower, and the startup feels quite smooth. However, the H6 usually offers more advanced options, like a 2.0T engine that can push the power above 190 horsepower, providing more aggressive acceleration. This sharing strategy is the manufacturer's way of cost control, allowing you to enjoy a similar driving experience when purchasing the H4, but the H6's engine tuning leans towards sportiness, resulting in slightly higher fuel consumption. For daily use, the difference isn't significant, but if you're after power, the additional engine version of the H6 is more worthwhile. Engine specifics depend on the exact year and configuration, so I recommend test driving both at a 4S dealership to compare the feel, rather than just looking at the specs on paper.

When comparing the H4 and H6 during my car shopping, I found their engines to be quite similar. Both models primarily use the same 1.5T engine, offering comparable initial acceleration and smooth driving experience. My friend's H6 didn't show any significant differences either. However, higher-end H6 variants might come with a 2.0T engine, delivering stronger acceleration and more noticeable power during uphill overtaking. In terms of maintenance, since the engines are shared, part replacements aren't expensive, but the H6's engine bears a heavier load and is more prone to carbon buildup, requiring more frequent servicing. Overall, for daily commuting, there's hardly any difference, with both offering average fuel efficiency. Opting for the H4 could save you some money. Just remember to check the vehicle identification code to confirm the engine model and avoid being misled.

I think there is an overlap between the H4 and H6 engines. The base models share a 1.5T engine with similar power output, around 150 horsepower, which is sufficient for city driving. However, the H6 offers an optional 2.0T version with superior performance, making it more suitable for high-speed demands. The advantage of engine sharing is easier maintenance and lower costs, but it's important to note that differences in engine load between the two models may affect longevity. In terms of driving experience, the difference is negligible if driven gently.
