Fuel efficiency is not significantly related to speed or the type and structure of the transmission. The key to saving fuel lies in controlling the engine's RPM. Here are the details: 1. On highways: If driving on a highway, maintaining a constant speed, such as around 110 km/h, and avoiding braking and sudden acceleration can help save fuel, as these actions may cause RPM fluctuations. 2. Engine RPM: For a 4AT transmission, these fluctuations become very noticeable. To achieve better fuel efficiency with a 4AT, the secret is to keep the engine RPM as stable as possible. The engine's RPM is the most critical factor affecting fuel consumption.

What procedures are required for purchasing compulsory traffic insurance for company-owned vehicles?

To purchase compulsory traffic insurance for a company-owned vehicle, you will need the organization code certificate, business license, vehicle registration certificate, and the previous year's insurance policy. Below are detailed introductions about company-owned vehicles: 1. Introduction: Company-owned vehicles refer to vehicles registered under the name of a company or enterprise. These vehicles do not need to repeatedly pay the vehicle and vessel tax during inspections, making them a popular means for urban residents to purchase and register vehicles. Compared to private vehicles, company-owned vehicles are more cost-effective. Moreover, most company-owned vehicles are maintained and repaired at 4S shops, with complete maintenance and repair records. 2. Price: Most company-owned vehicles are sold through mortgage due to company bankruptcy or other reasons, which makes their prices very affordable. Since company-owned vehicles are second-hand sales, only the transfer of ownership is required, unlike private vehicles that may have many unresolved traffic violations. For most people, company-owned vehicles are hard to come by and highly sought after.

What is the fuel consumption of the Volkswagen 1.4T Golf?

Golf 1.4T's actual fuel consumption is around 8L/100KM, while the MIIT's combined fuel consumption is 5.6L/KM. A fluctuation within 10% is normal. Here is the relevant introduction about fuel consumption: 1. Factors affecting fuel consumption: Environmental road conditions, climate conditions, personal driving habits, vehicle load, etc. Using air conditioning in the car is also a primary factor for higher fuel consumption. Driving with the air conditioning at maximum setting consumes 5-25% more fuel than driving with it turned off. 2. Calculation formula: Calculating a car's fuel consumption means calculating the fuel consumption per 100 kilometers, which is dividing the actual fuel consumption by the actual distance traveled. The calculation formula is: Fuel consumption per 100 kilometers equals fuel consumption (liters) divided by distance traveled (kilometers) multiplied by 100.
