BYD's 55km and 120km refer to the pure electric driving range. These numbers typically indicate the pure electric range of plug-in hybrid models. The 55km version can only travel about 55 kilometers on a full charge. For example, my daily commute is 30km round trip, so this car is more than enough. I just charge it at home in the evening, and the electricity cost is super cheap—only a few dozen yuan per month. It's fuel-free and eco-friendly. However, for longer distances, I need to switch to hybrid mode. The 120km version doubles the range, making it possible to drive 100km on weekends for outings without refueling, saving both hassle and fuel costs. BYD's battery technology is quite reliable. The 120km version has a larger battery capacity and slightly longer charging time, but it supports fast charging well. Overall, the 55km version is economical and suitable for pure city commuting, while the 120km version offers more flexibility for longer trips.

The 55km and 120km refer to the maximum distance BYD's hybrid vehicles can travel in pure electric mode. Models with higher numbers have larger battery capacities and stronger range. Some friends I know find the 55km version more than sufficient for daily commutes of around 40km, with electricity costs being much cheaper than fuel. The 120km version offers longer range for fewer fuel stops on long trips, with fuel consumption so low it's almost negligible. BYD's DM-i technology is highly efficient with durable batteries, and charging can be done using a standard power socket. The 120km version is slightly heavier, resulting in a small reduction in acceleration feel, but practicality is greatly increased. Economically, the 55km version has a lower initial price, but the 120km version saves more on fuel costs in the long run. It suits different driving habits depending on individual needs.

Where is the collision sensor located in the Audi C5?

Collision sensors are generally installed in the vehicle's B-pillar or the lower part of the doors. Definition of the Collision Avoidance System: The Collision Avoidance System (CAS), also known as the Pre-Collision System, Forward Collision Warning System, or Collision Mitigation System, is an automotive safety system designed to prevent or reduce the severity of collisions. In its basic form, the forward collision warning system monitors the vehicle's speed, the speed of the vehicle ahead, and the distance between the vehicles to warn the driver when the vehicle is too close, which may help avoid a crash. Causes of Collision Avoidance System Malfunction: Failure of the collision avoidance sensor is caused by loosening or short-circuiting; there may indeed be hard-to-observe obstacles in front of the vehicle, requiring reduced speed and careful observation to avoid a collision.

Does the Alto 4AT Transmission Need to Have Its Filter Replaced?

It is not necessary to replace it. If you don't remove the oil pan to change the transmission fluid, you cannot replace the filter. Transmission Fluid Replacement Interval: It is best to replace it once after 17,000 kilometers. Although manual transmission fluid does not cause discomfort when exceeding 17,000 kilometers, this is a critical point. Functions of Transmission Fluid: The transmission generates a significant amount of heat during operation, and the transmission fluid helps dissipate this heat. During daily driving, gears must be shifted according to driving conditions, and the transmission fluid needs lubrication to ensure smoother gear changes. It also helps keep the transmission system clean and extends the lifespan of the transmission components.

What is the channel number for Volkswagen oxygen sensors?

Volkswagen oxygen sensor channel numbers: range between 31 and 34. Function of the front oxygen sensor: The front oxygen sensor detects the oxygen concentration in the engine exhaust and transmits this information as an electrical signal to the ECU. The ECU then uses this oxygen concentration data to perform feedback control on the air-fuel ratio. Function of the rear oxygen sensor: Primarily used to detect the oxygen concentration in the exhaust after it has been treated by the three-way catalytic converter. If the oxygen concentration data obtained from the front and rear oxygen sensors is the same, it indicates that the three-way catalytic converter has failed.
