In reality, we often use great horses、to high power、To a series of numbers such as large torque to measure the performance of a car or comparison between several cars，But in fact, it is not accurate to define a car from these "dead" numbers，Otherwise, we can know the performance of all cars without buying a car when we buy a car，Where to run the West to test drive。Brother Tea will solve the confusion today，How do you refer to these performance figures to be close to reality。

Let's start with the horsepower，Because this value is actually mixed with many people，There are two in the unit: PS、BHP，There is also a to high power，What is going on? alright，Encyclopedia is here: Malaysia is the output that the car can be achieved.，Horse for horsepower uses PS as unit，and to high power data is the same meaning。So，We often say that the best of the seabet appbig horses and the power is actually the same，The relationship between the two is 1 horsepower = 0.7354987 kilowatt (kw)，Everyone compares the main output power of the two cars as long as there is no problem with the unified unit。

So what is another unit of horsepower BHP? This is the unit of British horsepower，Strictly speaking，"Horse" in the high horsepower generally refers to public (rice system) horsepower，Unit PS，and British horsepower is Britain、Units used in the United States，"BHP" and "HP" actually mean the same，Brake HORSE Power and Horse Power's abbreviation，It is easier to understand，1BHP = 0.73kW。British horsepower is actually rarely used，We are only in some Britain、Automotive programs in the United States often hear。Domestic said to the big horsepower or to high power is mainly public PS，How much is what we often say，Don't mix it。

So what kind of performance does Malaysia determine a car? One wrong point is that the larger the horsepower，Accelerate the faster。Horse power is indeed necessary to contact，But the high -speed performance of Dama Horse has a greater impact on the high -speed performance of cars，But we usually have no chance to try this speed，High speed limit is 120km/h。But our feelings of the big torque will be more sensitive，It is mainly reflected in the acceleration ability。

So the big torque，Is the acceleration of the vehicle faster? Not。To judge the acceleration performance, in addition to the large torque, you need to refer to the output curve of the torque，Because the torque is different at different speeds，We often see the main torque 300NM/2500rpm seabet appsimilar data，In fact, this car can output 300Nm to large torque at a speed of 2500rpm，We only know the torque performance under this speed time，How much torque is out of this car to Da Neng，Other I don’t know。But the expression method of large torque，We can still see some performance things，For example, when the car weight is equivalent，300nm/2500rpm is to accelerate or start in the front section of 300nm/1700rpm，Because the torque of the latter reaches 1700rpm, it reaches。If we compare from the entire torque curve，You can also see the middle -level acceleration ability，This determines the vehicle overtaking ability。So，The torque must be combined with the speed to have reference value，Otherwise, if you only refer to the torque，The torque of the truck can be larger，Why is it a high -speed "turtle" instead。

Of course，Brother Cha just tell everyone a theoretical reference method，Because the car is composed of tens of thousands of parts and components，The engine is just one of the core components，Output power from the engine，To the driving car to move forward through the gearbox and drive shaft，differentials, etc.，The transmission efficiency inside，The speed ratio setting of the gearbox，The shift speed and logic of the gearbox，Vehicle weight，Tire performance, etc.，So we often see the speed or start of a car with a high car engine parameter.。So do not think that the engine torque is large, you will start quickly，The engine power is high, and it must be high at high speed。
