Which generation is the GW4G15k engine?
3 Answers
GW4G15k is the 1st generation engine. Power of GW4G15K engine: GW4G15K is a 1.5L turbocharged engine with a maximum power of 150 horsepower and a maximum torque of 220 Nm. The turbocharger of the engine is independently produced by Honeycomb Weiling Power, and uses technologies such as VVT continuous variable valve timing, polymer material cylinder head cover, double overhead camshaft, and high tumble ratio intake port + multi-hole fuel injector. Advantages of GW4G15K engine: The power delivery of the 1.5T engine is linear, with a small burst after exceeding 2500 rpm. In standard mode, when stepping on the throttle at low speeds, the power comes relatively slowly, making it not particularly agile to drive.
I previously drove a Haval H1 equipped with the GW4G15K engine, which belongs to the first-generation model from Great Wall, launched around 2009. It's a 1.5L naturally aspirated engine with an output of around 88kW—adequate for city driving but somewhat sluggish on highways. During my own maintenance, I found its structure simple and upkeep affordable, with an oil change plus filter replacement costing just 200 RMB. However, its average fuel consumption of 8L/100km falls short compared to newer generations. In terms of generations, the first-gen is robust and durable—my car ran 150,000 km with only spark plug replacements, and minor issues were quickly resolved. That said, the second-gen models like the GW4B15 feature turbocharging, offering stronger power and better fuel efficiency. Still, the first-gen suits those on a tight budget. Overall, its reliability makes it a worry-free choice for beginners for a few years, just remember to clean the throttle body regularly.
When modifying cars, I've worked on the GW4G15k several times. It's Great Wall's first-generation engine with a base performance of 88kW—not particularly powerful, but with great modification potential. I installed a turbocharger kit, boosting it to 110kW for a more thrilling drive. In terms of generations, the first-gen has a simpler structure compared to the second-gen GW4B15, lacking direct injection technology, making it easier to tune yourself—cost-effective and cool. Commonly found in the Haval M2, it's sufficient for city commuting, though noise is noticeable at high speeds; upgrading the exhaust can reduce noise and improve efficiency. Factory fuel consumption is around 8L, rising slightly to 9L after modifications; pairing it with an intake upgrade helps balance it out. The best part of car modification is the transformation potential—you can enjoy the fun even on a modest budget. Just remember to maintain the spark plugs to avoid engine failure.
