Haval H6 Coupe is equipped with a 1.5T turbocharged engine. Here are the specific details about this engine: 1. 1.5T turbocharging indicates that the car's displacement is 1.5 liters, and the engine's intake method is turbocharged. 2. The 'T' in 1.5T stands for Turbo, representing turbocharging. Turbocharging (Turbo-Boost) is a technology that uses the exhaust gas generated by the operation of an internal combustion engine to drive an air compressor (Air-compressor). 3. Turbocharged engines on the market rely on turbochargers to increase the engine's air intake. A turbocharger (Turbo) is essentially an air compressor. It uses the exhaust gas from the engine as power to drive the turbine in the turbine chamber (located in the exhaust duct), which in turn drives the coaxial impeller (located in the intake duct). The impeller then compresses the fresh air delivered by the air filter pipe and sends it into the cylinder.
I understand the engine configurations of the Haval H6 Coupe. There are mainly two powertrain options. The 1.5T, codenamed GW4B15, is the main engine—a self-developed direct-injection turbocharged unit by Great Wall, featuring CVVL (Continuous Variable Valve Lift) technology that automatically adjusts valve lift based on throttle input, balancing fuel efficiency and power. It delivers 169 horsepower and 285 Nm of torque, making it both fuel-efficient and adequate for city driving, with a combined fuel consumption of around 8L/100km. The other option is a more powerful 2.0T, codenamed GW4C20, producing 197 horsepower and 345 Nm of torque, providing confidence for uphill climbs and overtaking, though it consumes 1-2L more fuel. Both engines are paired with a 7-speed dual-clutch transmission for smooth shifting and can run on regular 92-octane fuel without issues. Technologically, they feature optimized thermal management, with the turbo engaging quickly at 1,500 rpm and no heat degradation during prolonged high-speed driving, showcasing tangible progress in domestically developed engines.
I've been commuting with the H6 Coupe 1.5T for two years, and the engine performs steadily on a daily basis. With 169 horsepower, it starts off briskly, making it effortless to keep up with traffic during morning rush hours, and the turbo kicks in quickly without any lag. The fuel consumption is genuinely economical, averaging around 9 liters in city traffic jams and dropping to just over 7 liters on highways, which is more fuel-efficient than my friend's joint-venture SUV. Maintenance is straightforward too—just an oil change every 5,000 kilometers, costing about 300 yuan with semi-synthetic oil. Once when driving uphill on a mountain road, the engine noise became noticeably louder, but it's quite quiet on flat roads. I test-drove the 2.0T version, and the acceleration push is indeed stronger—overtaking is just a matter of stepping on the gas—but the daily fuel consumption goes up to over 10 liters, making it more suitable for those who frequently drive long distances. The powertrain and transmission work together smoothly, and for family use, the 1.5T is a more cost-effective choice.
