Difference between torque and horsepower in Cars

In cars, these parameters are essential. Most of the Lorries and other trucks had the torque and horsepower indicated. By knowing these parameters, you will be able to know the performance of the vehicle. However, these parameters have to be understood and what they represent for a vehicle. There is a relationship between that translates to the performance of the vehicle. In reality, these numbers play a more important role that the simple interpretation that the markets convey.

Torque vs Horsepower

Torque in a vehicle is the number for the work while horsepower is the rate of doing work. The more horsepower that is produced the more the torque potential of the car. The torque potential translates to the real world application that is conveyed through the vehicles transmission through the axle’s differentials. The role of gears is important in producing the horsepower level that the vehicle gives.

A good way of understanding the difference and the advantages and disadvantages between the two is to compare the case of a race care and a tractor. The racecar has the ability to develop enamours amount of the horsepower which means more work per second. On the other hand, torque is needed for speed through gearing. This means that for a racecar, there is not much work that is accomplished with the power from the engine thus there is more power that can be translated for speed.

On the other hand, a tractor that has the same size and performance ability with that of the race car producing the same amount of horsepower has the horsepower harnessed for doing work through gearing. The tractor will thus be able to do heavy work but at low speeds.

Simply put, if you are looking at the illustrations of a marketer, the higher the torque value the higher the acceleration you will get from the vehicle. The torque value at the wheels implies how fast the car can accelerate. On the other hand, the higher the horsepower, the heavier and the more work can be done by the vehicle.

The gearing system is usually responsible for the difference. The gearing system is responsible for the transmission of the power. If more power is used to create more rotations per minute then you will have a vehicle that moves at a high speed. On the other hand, if the gear system is such that more power is contained in the transmission, you will have a vehicle that can perform heavier tasks. You can have the same power from the engine but varying outcomes that create a difference in the attributes of the car.

Are HP and BHP the same thing?

In theory, “horsepower” -HP- and “brake power” -BHP- are totally different things. Supposedly BHP measures the amount of power once other parts such as the gearbox, alternator and water pump have been powered, it is basically the power that reaches the wheels. That would mean that all cars should be tested twice on the two totally different systems, but what really happens is that one HP is equivalent to 0.9864 BHP.

In the rare cases where vehicles are measured twice, things are really more confusing. The car manufacturers’ test benches offer very precise numbers. According to the U.S. standard, when Ford measured the 2.0-liter engine of the Focus ST, it got 255 horsepower. But when it measures the British version, it gets 250 horsepower.
