Here are the differences between manual transmission and automatic transmission: 1. Different principles: Manual transmission: The driver manually shifts the gear lever (shift knob) to change the gear meshing position inside the transmission, altering the gear ratio to achieve speed change; Automatic transmission: While driving, the driver operates the accelerator pedal as needed, and the automatic transmission can automatically shift into different gears based on engine load and vehicle operating conditions, automatically changing gears according to vehicle speed and engine RPM. 2. Features: Manual transmission: Stable performance, high transmission efficiency, and high fuel utilization; Automatic transmission: Convenient operation with flexible gear ratios. There are many types, including hydraulic automatic transmission, mechanical continuously variable transmission, electronically controlled mechanical automatic transmission, and dual-clutch automatic transmission. 3. Transmission efficiency: Manual transmission is purely mechanical, while automatic transmission relies on hydraulic torque converter for power transmission, resulting in differences in working efficiency, which directly leads to differences in fuel consumption.

What is a Water Car?

A water car refers to a vehicle that cannot be registered due to tax evasion, hence the name 'water car'. A smuggled car is a vehicle that has not been imported through the normal national import channels and has not been fully taxed, also known as an untaxed imported vehicle, which cannot be licensed. Classification of Smuggled Cars: Smuggled cars are generally divided into whole car smuggling and cut smuggled cars. The difference between the two is that the whole car maintains the original appearance; cut smuggled cars involve disassembling some parts of the car and smuggling them piece by piece. Hazards of Smuggled Cars: The danger of smuggled cars is that they do not have permits, invoices, or proper documentation. Once caught, traffic police will investigate the source of the vehicle and impound it.

Can the rearview mirror base be repaired separately?

The rearview mirror base cannot be repaired separately and requires replacement of the entire assembly. Below is more information about rearview mirrors: Location: Car rearview mirrors are located on both sides of the vehicle's front and inside the car's cabin. Rearview mirrors reflect the conditions behind, beside, and below the vehicle, serving as the "second pair of eyes" for the driver by indirectly showing these areas, thereby expanding the driver's field of vision. Classification: Rearview mirrors can be categorized by installation position into exterior mirrors, lower mirrors, and interior mirrors. By purpose, exterior mirrors reflect the rear and side of the vehicle, lower mirrors reflect the front and lower parts of the vehicle, and interior mirrors reflect the rear and interior conditions. Different purposes lead to variations in mirror structure.

Does the BYD Han have auto start-stop?

BYD Han does not have the auto start-stop function. Here is more information about the auto start-stop function: 1. Definition: Engine auto start-stop automatically shuts off the engine when the vehicle comes to a temporary stop during driving (e.g., waiting at a traffic light). When it's time to move forward again, the system automatically restarts the engine. Its English name is STOP&START, abbreviated as STT. The STT intelligent fuel-saving system is a set of systems that control engine start and stop. 2. Principle: The working principle of the start-stop system is that when the vehicle stops moving due to congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this time, the Start/Stop system automatically detects: the engine is idling and not in gear; the wheel speed sensor of the locking system shows zero; the electronic battery sensor indicates there is enough energy for the next start. After these three conditions are met, the engine automatically stops rotating.

Can a C1 License Drive a 9-Seater Car?

9-seater cars can be driven with a C1 driver's license. Most MPVs with no more than 9 seats, and whose length and weight fall within the category of small cars, can be driven with a C1 license. C1 License Permitted Vehicle Types: The C1 license allows driving small and micro passenger cars, light and micro cargo trucks, as well as light, small, and micro special-purpose vehicles. Small passenger cars must have a seating capacity of 9 or fewer people. Vehicles Not Permitted with a C1 License: Large buses, tractors, city buses, medium-sized buses, large trucks, regular three-wheeled motorcycles, regular two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and trams. Additionally, a C1 license does not permit driving vehicles with more than 9 seats or trucks with a total length exceeding 6 meters.

Is the Model 3 classified as A or B?

The Model 3 is a B-segment vehicle. Below is an introduction to the Model 3: 1. Body dimensions: The vehicle measures 4694mm in length, 1850mm in width, and 1443mm in height, with a wheelbase of 2875mm, classifying it as a mid-size sedan. 2. Functional features: The Model 3 does not utilize an aluminum body; instead, its body size is reduced by 20% to offset the impact of increased weight on range. The Model 3 is estimated to have a range of approximately 320 kilometers. 3. Powertrain: The all-wheel-drive version of the Model 3 has a total motor power of 340 kW and a total torque of 639 Nm. The rear-wheel-drive version features a motor with a maximum power of 202 kW and a maximum torque of 404 Nm. 4. Battery: The Model 3 uses ternary lithium batteries across all variants, which offer the advantages of higher energy density and lighter weight.

What does 12 cylinders mean?

12 cylinders refers to a 12-cylinder car engine, which is essentially the parallel connection of two V6 engines. Below is relevant information about car engines: Introduction: An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. Expansion: The term engine can refer to both the power-generating device and the entire machine including the power unit (e.g., gasoline engines, aircraft engines). The engine was first developed in the UK, so the concept of the engine also originates from English, with its original meaning referring to "a mechanical device that generates power."
