CA4GB15TD-30 is the engine model used in the Bestune T77, with a maximum horsepower of 169 hp, a maximum power of 124 KW, a maximum power speed of 5500 rpm, and a peak torque of 258 N.m. The Bestune T77 engine was independently developed by FAW Group, Bestune's parent company in China. For daily of the Bestune T77 engine, the following methods can be employed: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the requirements specified by the manufacturer. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the relief valve and carry contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. In small amounts, it remains suspended in the oil; in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

I drive a Bestune T77 daily and find its four-cylinder engine quite suitable for family use. The 1.5-liter turbocharged design makes urban driving exceptionally smooth, with no shaking during start-stop, and fuel consumption is controlled at around 8 liters per 100 kilometers. On the highway, it accelerates with enough power, climbs hills effortlessly, and has low cabin noise, making it comfortable for the whole family. Compared to a six-cylinder engine, it's lighter, more agile in steering, and more fuel-efficient, though it can get a bit noisy on long trips. It's recommended to regularly maintain the turbo part to avoid carbon buildup issues and to get a power test at a 4S dealership for peace of mind—economical, practical, and reliable.

From a technical perspective, the Bestune T77's engine features a standard four-cylinder configuration, equipped with a 1.5-liter turbocharger delivering a peak power of 169 horsepower and 258 Nm of torque. The direct fuel injection technology optimizes combustion efficiency. The four-cylinder layout reduces weight and noise, while the six-speed automatic transmission enhances smoothness and fuel economy. This design is more suitable for compact SUVs compared to V6 or three-cylinder engines, offering simpler structure and easier , though its output is slightly weaker at high speeds. An oil change interval of every 5,000 kilometers is recommended to ensure long-term reliability, with the overall design balancing performance and cost.

Having worked on cars for many years, the four-cylinder engine of the Bestune T77 is truly hassle-free to maintain. Parts are easy to find and cost-effective, with routine just requiring oil changes and spark plug replacements. Just be mindful of carbon buildup in the turbo for proper care, but overall it has a low failure rate. It drives smoothly with reasonable fuel consumption—around 7-8 liters in the city is more than enough.

From an environmental perspective, the Bestune T77's four-cylinder engine meets China's National VI emission standards with an average fuel consumption of 7.5L/100km, demonstrating better efficiency in suburban driving conditions. Compared to high-displacement vehicles, it reduces carbon footprint, making it suitable for urban commuting. Combined with automatic start-stop technology, it can further reduce fuel consumption. It's recommended to use higher-grade gasoline to improve combustion efficiency.

For driving enthusiasts, the FAW Bestune T77's four-cylinder turbocharged engine delivers a 0-100km/h acceleration in about 9 seconds, with particularly satisfying mid-range responsiveness. The steering is precise and handling stable, though road noise becomes noticeable during high-speed cruising. While more explosive than naturally aspirated six-cylinder engines, it has fewer aftermarket parts - but the factory tuning strikes an excellent balance between driving pleasure and comfort.
