Which is More Important: Horsepower or Torque?

Both horsepower and torque are equally important indicators. Horsepower is a unit of power, commonly used to measure automotive power, such as a car with 130 horsepower. Torque refers to the rotational force output from the crankshaft of the engine, inversely proportional to engine speed at a fixed power level—faster speeds result in lower torque. Like power, torque is a key metric of engine performance. Vehicles employ various torque-amplifying mechanisms, such as transmissions and differential gears, which multiply the relatively small torque initially produced by the engine to ultimately rotate the wheels and propel the vehicle forward.

How to Apply to Change an 8-Seater to a 7-Seater?

An 8-seater vehicle cannot be changed to a 7-seater. The passenger capacity is determined by the vehicle's factory certification and cannot be altered once approved. Any unauthorized addition or reduction of seats constitutes illegal modification. According to the regulations on motor vehicle registration, if a registered motor vehicle requires changes to its usage nature, body color, body or frame, the owner must apply for modification registration with the local vehicle management office. No unit or individual is allowed to assemble a motor vehicle or alter its registered structure, construction, or features without authorization. Any modifications to the chassis, engine, suspension, transmission system, steering system, tires and rims, lights, body color, exterior structure, or technical data of the motor vehicle without approval from the public security traffic management department—resulting in discrepancies from the data announced by the competent department of motor vehicle products under the State Council—are considered illegal modifications.

How Long Can National 5 Vehicles Continue to Be Driven?

National 5 vehicles can still be driven for 6 years, and within this period, there is no need to worry about emission standards or driving restrictions. According to the "Limits and Measurement Methods for Emissions from Light-duty Vehicles (China Phase 6)" released by the Ministry of Environmental Protection, the National 5 standard will remain in effect for vehicle inspections in China until July 1, 2025. After the implementation of the National 6 standard, National 5 vehicles will not be significantly affected. However, National 4 and National 3 vehicles may face mandatory scrapping in certain regions. For third- and fourth-tier cities, the implementation of the National 6 standard will be delayed accordingly, extending the usage period for National 4 and National 3 vehicles in these areas.

Will the tire develop wave-like deformation when driving at high speed with low tire pressure?

Tire pressure that is too low can cause wave-like deformation when driving at high speed. At high speeds, low tire pressure increases the contact area between the tire and the road, leading to a rapid rise in tire temperature and resulting in wave-like deformation, which can ultimately cause a blowout. In such situations, panicked steering may even lead to a rollover or loss of vehicle control, posing safety hazards to both the driver and others on the road. When tire pressure is too low, friction between the tire and the ground multiplies, causing the tire temperature to rise sharply, the tire to soften, and its strength to drop drastically. If the vehicle continues to drive at high speed under these conditions, a blowout may occur. Additionally, low tire pressure increases fuel consumption.
