In today's era of the automotive industry, various new energy models are emerging in an endless stream, and traditional fuel vehicles are constantly pushing new products. Whether it's for environmental protection and emission reduction, or in pursuit of a better driving experience, consumers are often troubled by various parameters when purchasing a car. The horsepower is not enough, the fuel consumption per 100 kilometers is too high, the safety performance is poor, the price is too expensive, and in the face of many doubts, it is necessary to analyze the various performance indicators of the car in order to make an informed car purchase decision.
Dynamic performance
The dynamic performance of automobiles has always been the focus of consumers' attention. Whether it is an internal combustion engine or a pure electric motor, the maximum horsepower and torque values of the engine directly determine the acceleration ability of the whole vehicle. The Toyota Corolla, for example, has a 2.0-liter engine that makes 169 hp and 205 Nm of torque, making it accelerate from 0 to 100 km/h in just 8.1 seconds. The Tesla Model 3's permanent magnet synchronous motor produces 283 hp and 530 Nm of torque, reducing its 0-100 km/h acceleration time to 5.6 seconds, which is basically comparable to that of a sports car. There are also differences in the power output characteristics of internal combustion engines and electric motors, with the former having a relatively flat torque curve and the latter having the advantage of instantaneous bursts.
Comparison of energy consumption performance
The energy consumption level of the car directly affects the cost of the car owner. For fuel vehicles, fuel consumption per 100 kilometers is the most important consideration. Taking Toyota Leling as an example, its fuel consumption is 5.9L per 100 kilometers, which is at the middle level among compact cars. For new energy vehicles, in addition to the power consumption of 100 kilometers, the mileage of the whole vehicle is also extremely important. Taking BYD Han as an example, its power consumption per 100 kilometers is only 13.7 kWh, and the maximum mileage can reach 605 kilometers, which greatly reduces the cost of use. The cost of refueling varies greatly between different models, with gasoline vehicles having to pay for fuel for a long time, while pure electric vehicles only need to be charged occasionally.
Handling safety assessment
No matter how powerful the power is, if the handling performance is not good, the car will be difficult to handle. A good production car should have excellent handling agility and allow the driver to control the movement of the body. Active and passive safety configurations are also indispensable, such as body anti-collision beams, airbags, active braking, etc., which can ensure the safety of occupants to the greatest extent. For new energy vehicles, battery safety performance is also the focus of consumers' attention. Due to the potential fire hazard of batteries, car companies need to take multiple protective measures to completely eliminate safety anxiety.
Comfort
In addition to power, energy consumption and safety, the comfort of the car is also an important indicator that cannot be ignored. Cockpit noise disturbance, an excellent car should minimize engine noise, wind shear sound, etc., to create a quiet riding environment for the occupants. The suspension damping effect can effectively suppress bumps and improve ride comfort by optimizing the shock absorber and spring settings. Finally, the configuration of the multimedia entertainment system also directly affects the entertainment experience in the car, and many models now use luxury configurations such as large central control screens and high-quality audio.
Comprehensive score for value performance
Looking at the above indicators, it is not difficult to find that the price of models with strong power, low energy consumption, safe handling and outstanding comfort will naturally be high. Therefore, when buying a car, you also need to consider the cost-effective performance of the car. The price range is positioned, and there are large differences between models in the same class. Value retention rate and maintenance costs, although some models are cheap, but the long-term use cost is very high. Finally, the overall rating of the user experience should not be ignored, after all, a good car should bring unparalleled driving pleasure.
