How much horsepower does a family car need? Seconds understand.
At present, cars on the market generally provide a variety of configuration models, including engines with different displacements. What kind of car consumers choose depends on the engine displacement, power parameters and gearbox matching.
The first thing that comes to mind about power is the engine displacement. Whether it is turbocharged or naturally aspirated, the displacement is different. For example, for cars equipped with 1.5L and 2.0L engines, consumers always feel that 1.5L has small displacement and sufficient power. This accident is somewhat biased. Whether the power is sufficient depends on factors such as vehicle weight and gearbox. For small family cars, regardless of other factors, 1.6L displacement engine has achieved good results in power output and fuel economy.
With the development of technology, the power of small displacement turbocharged engine is already very high, and it is not enough to judge the power only by displacement. There is a certain relationship between large displacement engines and small displacement engines. It is an indisputable fact that large-displacement vehicles have high fuel consumption, and overweight small-displacement engines may lead to high fuel consumption. Which one to choose depends on daily use. David Ashe, North Executive Force. )
The comparison of power parameters is what consumers often do before buying a car. You can't compare the figures of two cars. This means increasing the weight of the car. The thrust-to-weight ratio is the driving force divided by the vehicle weight. It can be seen that the greater the pressure difference, the greater the horsepower allowed per unit weight and the better the dynamic performance of the vehicle. (David Asher, North? Exposure (American TV series), the acceleration ability of the car also reflects whether the vehicle power is strong to some extent. Generally speaking, ordinary family driving only needs to destroy 10 seconds. If it exceeds this number, it will obviously slow down, indicating that the power is insufficient. On the contrary, it is powerful.
Gearbox is also the main standard to measure power. The most common gearboxes are CVT, DCT and AT. CVT is relatively economical, but it has many problems because of its small torque, fast DCT and complex structure. AT maintains ride comfort, economy and speed change, but the price is slightly higher. No matter what kind of gearbox, if it matches the engine more perfectly, the power of the engine will play better. How much horsepower does a family car need? Seconds understand.
Buying a car is a big deal for ordinary families. Whether the engine power of this car is strong or not depends mainly on the demand for the car at ordinary times. If one person uses it, a small-displacement model is enough. (william shakespeare, Hamlet, famous saying of automobile celebrities) If cars are loaded frequently, large-displacement models will have many benefits not only in terms of power, but also in terms of subsequent use costs. Most importantly, before buying a car, you must go to the store for a test drive according to your own car needs. After all, the feeling of actual driving is more direct than looking at the data.
