In this work, a simple methodology to follow the behavior of motorized urban vehicles, from the point of view of personal finances, is presented. Including the acquisition of a new vehicle, the analysis considers the driving distance per week, the average speed, the time spent at rest due to traffic conditions, the evolution of gasoline and electric energy prices, maintenance and services, and local taxes. Herein, two low-range compact vehicles were chosen and compared: one powered by combustion of gasoline, and the other by electric energy stored in batteries. Historical data and trend projections, according to inflation and prices evolution, are taken into consideration. The developed model may help to select adequately a new vehicle, according to the user’s needs. A good choice depends strongly on the usage and traffic conditions, the electric vehicle being suitable for large weekly driving distances and heavy traffic, whereas the gasoline vehicle is preferred for short distances and light traffic. The expenses of the vehicles are compared through time, with different scenarios envisaged according to the user’s resolution to keep the vehicle for the entire lifespan or to sell it quickly.

电动还是汽油：购买新车时决定的简单模型

在这项工作中，提出了一种从个人财务角度跟踪城市机动车辆行为的简单方法。包括购买新车在内，该分析考虑了每周的行驶距离、平均速度、因交通状况而休息的时间、汽油和电能价格的演变、维护和服务以及地方税收。在此，选择了两种低里程紧凑型车辆进行比较：一种由汽油燃烧提供动力，另一种由电池中存储的电能提供动力。根据通货膨胀和价格演变，考虑历史数据和趋势预测。开发的模型可以帮助根据用户的需求充分选择新车。一个好的选择在很大程度上取决于使用情况和交通条件，电动汽车适合每周行驶距离长和交通繁忙的情况，而汽油车则适合短距离和交通繁忙的情况。车辆的费用随时间进行比较，根据用户的决定设想不同的场景，是终身保留车辆还是快速出售。
