Chinese car brand 4, often mentioned in brand context Exeed or its TX4 range, is a complex engineering platform that requires a deep understanding of the specification. Owners and potential buyers are faced with the task of parsing alphanumeric symbols that hide key information about engine type, transmission and trim level. It is the decoding of the “4” code that allows you to determine whether we are talking about a four-cylinder engine, all-wheel drive or the fourth generation of the platform T1X. Without an accurate understanding of these nuances, it is impossible to correctly select spare parts or assess the real potential of a crossover on the road.
The modern market is oversaturated with offers where labeling is used as a marketing tool to highlight flagship versions. In the case of Chinese manufacturers such as Chery and its sub-brand Exeed, the number often indicates belonging to the premium segment within the model line. This implies a reinforced frame, more advanced safety systems and qualitatively different interior materials compared to the basic versions. Understanding this hierarchy is critical when reselling a car or assessing its liquidity on the secondary market.
Technical experts note that indexing also affects the operating algorithms of the electronic engine control unit. Software for versions labeled "4" often has excellent turbo and valve timing calibrations. This means that standard diagnostic procedures may produce incorrect data if the specifics of this modification are not taken into account. Therefore, when contacting a service center, you must immediately clarify the exact modification of the power unit.
Technical features and power units
Under the hood of cars identified through the prism of the “4” marking, power plants that are advanced for the manufacturer are usually hidden. Most often we are talking about gasoline turbo engines of the series Acteco volume 1.6 or 2.0 liters. These engines are equipped with direct fuel injection and variable valve timing, which provides high torque at low speeds. Turbocharger in such units it is selected to minimize turbo lag, ensuring linear power delivery.
The transmission group also undergoes changes depending on the specific implementation of the Quartet. In most cases, a robotic gearbox with two wet clutches is used. This design allows it to withstand high torque and ensures fast gear changes. However, unlike dry robots, regular oil and filter changes are required here, since friction disc wear products enter the working fluid.
- 🚗 Engine: Turbocharged, direct injection, aluminum cylinder block.
- ⚙️ Transmission: DCT robot with two clutches in an oil bath.
- 🛡️ Drive: Optional all-wheel drive with latest generation clutch.
- ⛽ Ecology: Compliance with Euro-5 and Euro-6 standards.
⚠️ Attention: Using fuel with an octane rating below AI-95 can lead to detonation and damage to the piston group of a high-compression engine.
The all-wheel drive system, if present, is based on an electro-hydraulic clutch. It is capable of transferring up to 100% of torque to the rear axle in a split second when the front wheels slip. This makes the car confident not only on asphalt, but also on light off-road or slippery winter roads. The critical element here is the coupling cooling system, which prevents it from overheating under prolonged loads.
Electronics and on-board systems
It is impossible to imagine a modern Chinese car without a complex set of electronic equipment. Brand “4” in this context often implies the presence of a multimedia system with a screen diagonal of 10 inches or more and support for interfaces Apple CarPlay and Android Auto. The head unit software is regularly updated, bug fixes and new features added. However, the firmware should be carried out only through authorized dealer centers in order to avoid “bricking” the blocks.
Active safety systems deserve special attention. Top trim levels include radar cruise control, all-round cameras with 3D modeling and a lane keeping system. Parking sensors react to the slightest obstacles, displaying an image on the screen with high detail. All these systems are connected to a central gateway, which processes huge amounts of data in real time.
CAN bus technical details
The data transfer rate in modern Chinese cars reaches 500 kbit/s, which requires the use of high-quality diagnostic equipment to correctly read errors. Cheap scanners may not see specific body control units.
The energy consumption of the on-board network has also increased. The presence of many energy consumers requires the installation of a battery with increased capacity and reliability. The generator set must produce a stable voltage even at idle speed to avoid sags that can cause sensor failures. Voltage stabilizers in power supply circuits of sensitive electronics play a key role in the longevity of control units.
Body and aerodynamics
The appearance of cars in this category is formed taking into account modern trends in aerodynamics. The drag coefficient is carefully calibrated in the wind tunnel to reduce fuel consumption and cabin noise at high speeds. The body is assembled using high-strength steels, the share of which in the total weight can reach 70%. This ensures high torsional rigidity and passenger safety in case of an accident.
The quality of the paintwork is also a source of pride for manufacturers. Multi-layer protection includes phosphating, primer, base and varnish. However, despite claims of corrosion resistance, experts recommend additional anti-corrosion treatment of hidden cavities. Particular attention should be paid to thresholds, side members and inner surfaces of doors where moisture can accumulate.
- 🎨 Coating: Multi-layer varnish with metallic or pearlescent effect.
- 🛡️ Protection: Double-sided galvanization of key body elements.
- 🌬️ Aerodynamics: Optimized fairings and spoilers.
- 🔩 Fasteners: Bolts and nuts with improved anti-corrosion coating.
⚠️ Attention: When washing the body with high pressure, avoid direct contact with the jet on the joints of the glass and the gas tank flap, so as not to damage the tightness of the seals.
The optics in such cars are most often LED, with adaptive light and automatic high beam switching. The headlights have a complex internal structure of lenses and reflectors, ensuring uniform distribution of light flux. Replacing optical elements can be expensive due to the integration of ignition and control units into a single design.
Suspension and ride quality
The chassis of cars falling under the "4" brand description is usually built using a MacPherson strut design at the front and a multi-link design at the rear. This arrangement allows you to find a balance between comfort and controllability. Engineers adjust shock absorbers and springs taking into account Russian road conditions, making the suspension quite energy-intensive. However, the service life of silent blocks and ball joints directly depends on driving style and the quality of the road surface.
The steering is equipped with an electric booster, which provides lightness at low speeds and informativeness on the highway. Depending on the driving mode (eco, sport, comfort), the steering force may change. Diagnostics of the power steering system requires connection to specialized software to calibrate the steering wheel position sensor after any intervention in the steering column.
The braking system is equipped with ventilated discs front and rear. Availability of an electronic parking brake with function Auto Hold becomes the standard. This feature keeps the car in place when stopping, which is especially convenient in city traffic jams. Brake pads must be of high quality to avoid squeaks and rapid wear of the discs.
Maintenance and consumables
Regular maintenance is the key to long service life of any complex mechanism. For cars of this class, oil change intervals can vary from 10 to 15 thousand kilometers, but in urban use it is better to reduce this period to 7-8 thousand. This is due to frequent warm-ups, traffic jams and short trips, which do not allow the oil to reach operating temperature and evaporate condensation.
Filter elements also require attention. The engine air filter and cabin filter must be changed every other oil change. The fuel filter in modern direct injection systems is often integrated into the fuel pump module and requires replacement less frequently, but if low-quality fuel is used, its service life can be sharply reduced.
| Component | Replacement interval (km) | Type of fluid/material | Note |
|---|---|---|---|
| Motor oil | 7 000 - 10 000 | Synthetics 5W-30 / 5W-40 | API SN approval or higher |
| Manual transmission oil | 60 000 | Specific DCT | Only original or analogues |
| Antifreeze | 90 000 | G12++ / G13 | Do not mix different colors |
| Brake fluid | 40 000 | DOT-4 | Humidity control |
☑️ Checklist before maintenance
Spark plugs in turbocharged engines are subject to high stress. It is recommended to change them every 30-40 thousand kilometers. Using spark plugs with the wrong heat rating can lead to overheating or, conversely, carbon deposits. Ignition coils are also consumables, although their resource is usually longer.
Common problems and solutions
Despite the overall high quality, all cars have their own “childhood diseases”. Owners may experience periodic failures of the multimedia system, which can be resolved by rebooting or updating the firmware. Sometimes parking sensors do not work correctly due to dirt or moisture, which can be solved by cleaning or replacing the element.
Gearbox noise at low speeds may be a design feature of dry or wet robots, but excessive noise requires bearing inspection. Knocking in the suspension is often caused by wear on the stabilizer bushings, which are the weakest link in bad road conditions. Timely replacement of these inexpensive parts allows you to maintain comfort and prevent wear and tear on more expensive levers.
Tip: When buying a used car, be sure to check the history of software updates and the absence of errors in the memory of the control units, even if the “Check Engine” is on.
⚠️ Attention: Ignoring transmission fault signals can lead to expensive mechatronics repairs or clutch replacement as soon as possible.
Problems with starting the engine in cold weather may be related to the quality of the fuel or the condition of the battery. In winter, it is recommended to use pre-heaters or install the car in a heated garage. It is also important to monitor the condition of the spark plugs and injectors, as their contamination makes a cold start difficult.
