4 Answers
Haval H9 engine is independently developed by Great Wall. Its body dimensions are: length 4856mm, width 1926mm, height 1900mm, with a wheelbase of 2800mm, minimum ground clearance of 206mm, fuel tank capacity of 80 liters, and curb weight of 2285kg. The Haval H9 features double-wishbone independent front suspension and multi-link independent rear suspension. It is equipped with a 2.0T turbocharged engine delivering maximum horsepower of 224PS, maximum power of 165kW, and maximum torque of 385Nm, paired with an 8-speed automatic transmission.
I'm a car enthusiast and have driven many domestic models. The Haval H9's engine is independently developed by Great Wall, called the GW4C20, a 2.0-liter turbocharged unit. Technologically, it draws some foundational inspiration from Japan's Mitsubishi but combines European and American design elements to create its own version, utilizing direct fuel injection and variable valve timing to enhance efficiency. The power delivery is smooth, with no noticeable jerking during acceleration, and the throttle response is sharp on highways, with ample mid-to-high-range thrust. In terms of reliability, based on my tests, it performs dependably in harsh conditions with few minor issues. I've also compared it to the Toyota Prado's engine in the same class and found the H9's to be more fuel-efficient, averaging around 10 liters per 100 km in city driving, making it suitable for off-roading. Great Wall continuously upgrades it, adding intelligent control modules to optimize performance. Overall, this represents progress in domestic technology, offering high cost-effectiveness.
As a car owner, I've been driving the Haval H9 for almost two years now, equipped with Great Wall's in-house GW4C20 series engine, the 2.0T variant. The technology stems from Great Wall's internal R&D team, initially drawing inspiration from Japanese engine elements but now fully self-developed, utilizing turbocharging to enhance low-end torque. In daily use, the engine provides smooth starts, effortless hill climbing, and commendable noise insulation during long-distance drives. It has shown few common issues; after driving 100,000 kilometers, no major problems have surfaced, only requiring a single spark plug replacement. Mechanics I've consulted mention this engine boasts low repair costs and straightforward maintenance. Compared to my friend's Japanese car, it offers stronger initial acceleration but slightly higher fuel consumption, averaging 11 liters. The engine's durability is impressive among SUVs, making it ideal for family trips. With regular maintenance, its lifespan can be extended, showcasing solid overall performance.
I've been studying automotive engineering for several years. The Haval H9's engine is the GW4C20, independently developed by Great Wall Motors, incorporating technological elements from Japan, Europe, and America. Independent R&D is crucial, and it utilizes turbocharging design to enhance performance, delivering smooth power output when driven. The reliability is quite high.
