The need for an urgent engine oil change G4FS Most owners experience 1.6 Turbo at 7,500 km instead of the standard 15,000 km. Chery Tiggo 8 Pro Max 2022 due to harsh operating conditions in city traffic jams. Ignoring this requirement in the early stages of owning a crossover often leads to stuck piston rings and increased waste of lubricating fluid, which is confirmed by numerous compression measurements at service stations. Owners who immediately switched to a reduced service interval note stable operation of the turbocharger and no problems with the system VVT.
Adaptation of robotic gearbox DCT7 requires careful attention in the first 3,000 kilometers, since switching algorithms are actively learning the driving style of a particular person. Sharp jerks when switching from first to second gear in city mode are often not a defect, but a feature of the calibration mechatronics, which smooths out over time. However, if the jerking is accompanied by vibrations or extraneous noise, immediate diagnostics of the control unit software is required.
All-wheel drive system AWD based on the sixth generation BorgWarner coupling, it demonstrates high speed of rear axle coupling, but requires regular checking of the condition of the electromagnetic coil. During the winter period of operation of 2022-2023, cases of overheating of the unit were recorded during prolonged slipping in deep snow, which led to a temporary shutdown of the rear circuit. To prevent emergency situations, it is recommended to avoid prolonged loads on the transmission in 4WD Lock no need.
Technical characteristics and power plant
The heart of the model Tiggo 8 Pro Max A 1.6-liter turbocharged petrol engine develops 186 horsepower and 275 Nm of torque. This unit, known under the index G4FS, equipped with direct fuel injection and a variable valve timing system on both shafts. The cylinder head design is made of aluminum alloy, which provides excellent heat dissipation, but increases the requirements for the quality of the fuel and antifreeze used.
The engine is paired with a 7-speed robotic gearbox with two wet clutches, which ensures quick gear changes and high efficiency. Engineers Chery The transmission has been tuned for a comfortable ride, so in economy mode it tends to shift to higher gear as quickly as possible to reduce consumption. Dynamic characteristics allow the car to accelerate to 100 km/h in 8.6 seconds, which is an excellent indicator for a seven-seat crossover of this class.
Technical nuances of the G4FS engine
The engine is equipped with balancing shafts that reduce vibrations and a plastic intake manifold with variable geometry. The timing chain resource is declared by the manufacturer to be up to 200,000 km, but real conditions can reduce this period.
The high-pressure fuel system is paired with a turbocharger with an electronic wastegate, which minimizes the effect of turbo lag. Critical Parameter is the octane number of gasoline: using fuel below AI-95 can cause detonation and damage to the piston group. The electronic engine control unit constantly monitors combustion quality and, if necessary, adjusts the ignition timing.
- 🚀 The dynamics of acceleration to 100 km/h is less than 9 seconds in equipped condition.
- ⚙️ Torque is available in a wide range from 1750 to 5000 rpm.
- 🛡️ The turbine resource is designed for the entire service life of the engine, subject to oil change intervals.
Transmission and all-wheel drive system
The basis of the transmission is a robotic box DCT7, developed in technological partnership with the company Bosch. A special feature of this version is the use of “wet” clutches that operate in an oil bath, which ensures effective cooling and high wear resistance of the friction discs. Unlike “dry” robots, this design better withstands city traffic jams and frequent starts from a standstill, although it requires regular replacement of the working fluid.
All-wheel drive system AWD is based on an electro-hydraulic clutch, which is capable of transferring up to 100% of the thrust to the rear axle if necessary. The control unit analyzes many parameters: accelerator pedal position, steering angle, wheel speed and accelerometer data. In normal driving conditions, the car is predominantly front-wheel drive to save fuel, engaging the rear wheels only when slipping or under hard acceleration.
To control traction, the driver can use the driving mode selector, which changes the operating algorithms of the engine, gearbox and clutch. In mode Sport the transmission maintains higher speeds, and the all-wheel drive clutch is constantly ready to transmit torque. Winter mode Snow smoothes the response to the gas pedal and prevents slipping on slippery surfaces, which is especially important for a heavy car with a high center of gravity.
⚠️ Attention: Long-term driving with a completely locked all-wheel drive clutch on asphalt with good grip can lead to overheating of the unit and its premature failure. Use the mode
4WD Lockonly to overcome difficult areas.
Suspension, steering and brakes
Suspension design Tiggo 8 Pro Max includes an independent MacPherson strut at the front and a multi-link design at the rear, which is standard for cars in this class. The engineers managed to find a balance between comfort and handling, but the shock absorber settings are closer to soft, which passengers like, but can cause nose-dive during hard braking. The rear multi-link effectively absorbs minor bumps, but at high speeds when cornering, noticeable body roll is possible.
The steering is equipped with an electric power steering mounted on a shaft, which provides good information content and the absence of vibrations on the steering wheel. Depending on the selected driving mode (Comfort, Sport, Eco) the force on the steering wheel changes: in sport mode it becomes heavier and sharper. The rail has good protection from moisture and dirt, which has a positive effect on the service life of the unit in Russian road conditions.
The braking system includes ventilated discs front and rear, as well as electronic parking brakes with Auto Hold. Braking efficiency is high even with repeated cycles, thanks to high-quality pads and calipers. However, owners should take into account the heavy weight of the car and increase the distance to the vehicle in front, especially when the cabin is fully loaded.
- 🛞 The rear suspension effectively isolates the body from vibrations of gravel roads.
- 🎯 The steering has zero play in the near-zero zone.
- 🛑 Stabilization system ESP works unobtrusively, intervening only when there is a real danger.
Interior, multimedia and ergonomics
