Haval H6 uses two engines, one is a 1.5-liter turbocharged four-cylinder engine, and the other is a 2.0-liter turbocharged four-cylinder engine. The 1.5-liter turbocharged engine has a maximum horsepower of 169 hp and a maximum torque of 285 Nm, with maximum power output at 5000 to 5600 rpm and maximum torque output at 1400 to 3000 rpm. The 2.0-liter turbocharged engine has a maximum horsepower of 224 hp and a maximum torque of 385 Nm, with maximum power output at 5500 rpm and maximum torque output at 1600 to 3600 rpm. The front suspension of the Haval H6 uses a MacPherson independent suspension, and the rear suspension uses a double-wishbone independent suspension. The double-wishbone suspension can suppress the body's roll amplitude and improve the car's handling.

The engine configurations of the Haval H6 are quite interesting, with several versions available. The early models used the older-generation Mitsubishi 4G63 engine, but later Great Wall developed its own 1.5T gasoline engine. The current third-generation H6 primarily features the GW4B15 series 1.5T direct-injection turbocharged engine, which has an all-aluminum block and includes CVVL (Continuous Variable Valve Lift) technology. The 2.0T version is equipped with the 4N20 series high-pressure direct-injection engine, with a 350bar fuel injection pressure for higher thermal efficiency. The hybrid models now use the Lemon DHT two-speed hybrid-specific engine, achieving a thermal efficiency of 38%, which is quite impressive. In terms of driving experience, the 1.5T offers sufficient low-end power and good fuel economy, while the 2.0T provides strong burst power, making overtaking very easy.

I drive a 2021 Haval H6 equipped with Great Wall's in-house GW4B15C 1.5T engine. The engine cover is covered with fancy English labels that look premium. In real-world driving, the 170 horsepower is adequate for this vehicle, and the low-end torque is well-tuned, making turbo lag barely noticeable in city driving. I heard the latest model even upgraded to Miller Cycle technology, achieving around 8L/100km fuel consumption. Once chatting with a fellow owner, he mentioned that while the early H6's Mitsubishi 2.4L engine was durable, it guzzled fuel. The current 1.5T is more economical for daily use, and the lifetime engine warranty provides extra peace of mind.

As someone who enjoys studying technology, I find the engine highlights of the 3rd-gen H6 lie in its breakthroughs in independent technology. Take the 1.5T model's CVVL (Continuously Variable Valve Lift) technology for example – this kind of feature used to be exclusive to luxury brands. The integrated exhaust manifold design in the cylinder head enables faster engine warm-up, especially noticeable in winter when the coolant temperature rises quickly. Dual VVT and an electric water pump also represent solid technological upgrades. The 2.0T model comes equipped with 350bar high-pressure direct injection + twin-scroll turbo, delivering its peak torque of 325Nm at just 1800rpm – the acceleration from traffic lights gives stronger kick-in-the-back sensation than many joint-venture vehicles.

Recently accompanied a friend to test drive the new H6, where the salesperson emphasized the engine upgrades. The all-new 1.5T four-cylinder model GW4B15L boasts a thermal efficiency of 38% and a combined fuel consumption reduced to 7.1L. The technical details were quite professional, mentioning features like a 350bar centrally-mounted fuel injector for better atomization and high-tumble intake ports to enhance combustion efficiency. The 2.0T version sees a torque surge to 385Nm, paired with a 9-speed dual-clutch transmission for particularly brisk performance. The hybrid version utilizes a dual-motor two-speed DHT, where the engine only generates electricity at low speeds and directly drives the wheels only at full throttle, with a 60km pure electric range sufficient for urban commuting.
