What engine is equipped in the Bestune T77?

[SanJuliet]

Bestune T77 is equipped with a 1.2T direct-injection turbocharged engine, the 4GA series high-performance engine, which balances high power and economy. The engine has a maximum power of 100 kW, a maximum power speed of 5500 rpm, a maximum torque of 204 Nm, and a torque range of 1600 to 4200 rpm. Taking the Bestune T77 2020 PRO 280TID manual luxury model as an example: its engine is a 1.5T 169 horsepower L4, the transmission is a 6-speed manual, and its body dimensions are 4525mm in length, 1845mm in width, and 1615mm in height.

The Bestune T77 is equipped with two turbocharged engines, a 1.2T and a 1.5T. I’ve actually seen quite a few owner pickup records at the dealership. The 1.2T model is called the CA4GA12TD, with a maximum output of 143 horsepower, which is more than enough for daily city driving, and it feels quite nimble when starting from traffic lights. The 1.5T version offers more power at 169 horsepower, making it more confident when climbing hills or overtaking. Both engines are four-cylinder units, unlike some three-cylinder engines that tend to vibrate, so they deliver smooth performance. The transmission is a 7-speed wet dual-clutch, with smart shift logic that keeps the RPM low during highway cruising. It runs on regular 92-octane gasoline, so it doesn’t require premium fuel, making maintenance costs quite affordable.

I've been driving the top-trim 1.5T B70 T77 for two years, and this engine really has some tricks up its sleeve. For daily commuting, the throttle response is precise, and the turbo kicks in early—you can feel the surge around 1,500 rpm, making merging onto ramps a breeze. The most impressive part is the fuel efficiency: just over 8 L/100km in city traffic, and it’s hit as low as 6.3 L/100km on the highway, which is quite frugal for an SUV. The auto start-stop system works well, though the occasional startup vibration is slightly noticeable. The stock cooling system is well-designed—even pushing it on mountain roads in 40°C summer heat hasn’t triggered any warning lights. Just remember to change the oil every 5,000 km.

Besturn put thought into equipping the T77 with 1.2T and 1.5T engines. The 1.2T targets the entry-level market, lowering the threshold to attract young consumers; the 1.5T supports the flagship positioning with 169 horsepower, confidently competing with rivals. Both engines use a self-developed platform, featuring direct injection and low-inertia turbo technology, with aggressive compression ratios but good fuel adaptability. The smartest move was adapting a 48V mild hybrid version, making auto start-stop and energy recovery feel natural while directly meeting China 6b emission standards. From an R&D perspective, this serves as Besturn's stepping stone for technological transformation.

Having repaired over thirty T77 engines, there are three common issues to watch out for with this machine. First, the turbo intake pipe clamp tends to loosen, causing air leaks and misfires. Second, the valve cover tends to leak oil, usually fixed by replacing the sealing ring. Third, the water pump impeller in older models is prone to corrosion due to material issues. Maintenance advice: change the engine oil every 7,500 kilometers, and never skimp on quality by using cheap filters. The air filter must be replaced every 20,000 kilometers, as the turbo is particularly sensitive to dust. Parts prices are 30% lower than joint-venture brands, making repair costs quite friendly for average families.
