There are three main evaluation indicators for automobile fuel economy, primarily focusing on testing fuel consumption per unit distance traveled. They are: 1. Fuel consumption per unit distance traveled; 2. Fuel consumption per unit transport workload; 3. Distance traveled per unit of fuel consumed. Additional information: 1. Automobile fuel economy refers to the ability of a vehicle to travel economically with minimal fuel consumption while ensuring sufficient power performance. In other words, it measures the capability to complete transport tasks with the least fuel consumption. 2. The fuel consumption parameter indicates the amount of fuel consumed per 100 kilometers traveled, measured in liters (L). In China, these indicators are determined by automobile manufacturers through prototype vehicle testing according to national standard test procedures.

As a frequent driver, I believe there are several key indicators of fuel economy. The most commonly used is fuel consumption per 100 kilometers, measured in liters per 100 kilometers (L/100km) – the lower the better. For example, a car with 5L/100km is very fuel-efficient. Another metric is miles per gallon (MPG), predominantly used in imperial system countries, where higher values indicate better efficiency (you can convert between these units). There's also driving cycle fuel consumption, which provides separate test data for urban and highway conditions. Official fuel consumption figures released by authorities often include combined values. Don't overlook the CO2 emissions indicator (g/km) – higher fuel consumption vehicles emit more. Through my mobile app tracking, I've noticed highway cruising yields lower consumption, while urban traffic jacks it up by over 30%. When considering new cars, I recommend checking these metrics and aligning them with driving habits – gentle acceleration and reduced braking can improve economy by 20%, and regular maintenance saves money too. Understanding these factors ultimately helps save both money and the environment.

When selecting or changing a car, I pay attention to several fuel economy indicators. The most basic is the combined fuel consumption, expressed in liters per 100 kilometers (L/100km). A lower number indicates better fuel efficiency, which is suitable for daily cost calculations. Another indicator is miles per gallon (MPG), used for imported cars or overseas data, making comparisons easier. Driving cycle fuel consumption is divided into urban and highway scenarios, with official tests providing average values, though real-world driving may differ by 10-20%. There's also equivalent emissions, such as carbon dioxide (CO2 g/km), which is useful from an environmental perspective. I've compared different models and found that compact cars consume 20-30% less fuel than SUVs. In actual driving, factors like tire pressure and air conditioning usage affect the results. Developing fuel-saving habits, such as maintaining a steady speed, can improve efficiency. It's advisable to check the vehicle manual or manufacturer's data.

Regarding fuel economy, I believe the key metrics are liters per 100 kilometers (L/100km) and miles per gallon (MPG). These figures allow for quick comparisons of how cost-effective different vehicle models are. Driving conditions have a significant impact; fuel consumption tends to be higher in congested urban traffic. CO2 emissions are also relevant, as higher levels increase one's carbon footprint. I've noticed most people only look at advertised data, but actual values measured through apps are more accurate.
