China 6 is better. The following are the differences between China 5 and China 6: 1. Different carbon monoxide emission requirements: China 5 vehicles have a carbon monoxide content of 1000mg per kilometer; China 6 vehicles have a carbon monoxide content of 500mg per kilometer. 2. Different issuing departments: The China 5 standard was issued by the Ministry of Environmental Protection; the China 6 standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine. 3. Different control levels: The emission control level of the China 5 standard is equivalent to the European Stage 5 emission standard currently in effect; the emission control level of the China 6 standard is a standard formulated to prevent and control environmental pollution caused by exhaust emissions from compression-ignition and gas-fueled spark-ignition engine vehicles and to protect human health.

Can Auto Start-Stop Technology Save Fuel?

Auto start-stop technology is relatively fuel-efficient. Here is a detailed introduction to auto start-stop technology: 1. The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine to continue driving. 2. The engine auto start-stop system is one of the most rapidly developing eco-friendly automotive technologies in recent years, especially suitable for stop-and-go urban driving conditions. This system can achieve up to 15% fuel savings in urban driving scenarios. The auto start-stop system is very convenient to use—during driving, simply press the brake pedal fully. After the vehicle comes to a complete stop for about two seconds, the engine will automatically shut off. As long as the brake pedal remains pressed, the engine will stay off. 3. Just release the brake or turn the steering wheel, and the engine will immediately restart automatically, allowing you to press the accelerator to start moving. The entire process usually remains in D gear. Direct injection engines are more suitable for this technology. Of course, when using a vehicle equipped with this feature, it's essential to use high-quality engine oil; otherwise, the system may not function effectively.

What are the body dimensions of the BAIC Changhe Q35?

The BAIC Changhe Q35 has a body length of 4286mm, width of 1815mm, and height of 1665mm, with a wheelbase of 2560mm. Here are the detailed specifications of the BAIC Changhe Q35: 1. The BAIC Changhe Q35 is equipped with a 1.5-liter naturally aspirated engine coded A151 across all variants. This engine delivers a maximum power of 85kW and a maximum torque of 148Nm, with the maximum power achieved at 6000 rpm and the maximum torque at 3800 rpm. 2. The engine features multi-point fuel injection technology and utilizes an aluminum alloy cylinder head and block. It is paired with either a 5-speed manual transmission or a 4-speed automatic transmission (4AT). The AT transmission offers smoother gear shifts and better reliability and durability. 3. The BAIC Changhe Q35 uses a MacPherson strut independent suspension at the front and a torsion beam non-independent suspension at the rear. Compact SUVs typically employ torsion beam rear suspensions due to their simple structure, compact size, and space efficiency. The use of a torsion beam rear suspension also helps to maximize rear passenger space and trunk capacity.

What is the fuel tank capacity of the Vellfire?

The fuel tank capacity of the Vellfire is 58 liters, as officially announced. Owners who have purchased the Vellfire can also check this information on the vehicle's configuration sheet. The Vellfire uses 92-octane fuel, with a fuel consumption of 7.1L per 100 kilometers. A full tank allows for a driving range of approximately 817km. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. Under normal circumstances, the fuel level is accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel added may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safe fill limit, with additional space between the safe fill limit and the tank opening. This extra space ensures that fuel expansion due to temperature increases does not cause overflow. If fuel is filled up to the tank opening during refueling, the actual amount added may exceed the marked capacity.

Should Transmission Fluid Be Changed at a 4S Shop or a Repair Shop?

Transmission fluid can be changed either at a 4S shop or a repair shop, but it is advisable to choose a reputable repair shop. Transmissions come in several types, including manual transmission (MT), hydraulic automatic transmission (AT), dual-clutch transmission (DCT/DSG), continuously variable transmission (CVT), and automated manual transmission (AMT). Both MT and AMT are mechanical transmissions and use the same type of fluid. Although DCT and DSG are also mechanical transmissions, they require special fluids due to their highly precise construction. AT and CVT transmissions require regular fluid changes. The functions of transmission fluid include: Maintaining the cleanliness of the gear system, lubricating transmission components, altering gear ratios, increasing the torque and speed of the drive wheels, enabling the vehicle to reverse, and facilitating gear shifts or power output. Signs that indicate the need for a transmission fluid change are: Vehicle shaking, jerky gear shifts, transmission overheating warnings on the dashboard, engine stalling, and unusual noises. Transmission maintenance methods include: Regularly checking the fluid level, avoiding skipping gears when shifting up, not forcing the transmission into neutral, not shortening the warm-up idling time, and avoiding gear grinding when shifting.
