What is the difference between horsepower and brake horsepower?
When it comes to your car’s performance, you’ve probably heard of terms like horsepower (hp) and brake horsepower (bhp). These figures give you an idea of your vehicle’s power – essentially, how much strength your car has under the bonnet. But what exactly do they mean?
We’ve pulled together a quick and simple guide to help you understand these key terms.
What is horsepower?
Horsepower is a measure of the power produced by your engine. The higher the horsepower, the more power your engine generates, which is crucial for acceleration and speed. However, horsepower doesn’t directly tell you how fast your car can go – that depends on other factors like weight and power-to-weight ratio. So, a lighter city car with, say, 150 horsepower might feel quicker than a heavier SUV with the same power.
You might also come across different terms for horsepower: Pferdestarke (PS), Kilowatt (kW), or Chevaux vapeur (CV). They’re just different units of measurement, much like how miles and kilometres are used to measure distance. So don’t be alarmed if you see different figures, it’s all essentially the same thing!
What is brake horsepower?
Brake horsepower, or bhp, measures how much power your engine produces once it’s transferred to the wheels, helping your car accelerate. While horsepower shows the engine’s potential, brake horsepower gives a more accurate picture of how much actual force makes it to the road.
What about torque?
Torque is another important measure. It’s the rotational force that drives your car’s acceleration. If you’ve ever tried to climb a steep hill or accelerate quickly, you’ve felt torque in action. A vehicle with high torque can power through tough conditions and give you quicker acceleration, especially when going from 0 to 62mph.
For vehicles like trucks, where strength is more important than speed, high torque figures are more critical than high horsepower. But in a sports car, a balance of both horsepower and torque is essential for a thrilling drive.
Why should you care about your car’s braking?
Now, while horsepower and torque can give you an idea of your car’s acceleration and performance, it's important not to forget the other side of the equation: your brakes! No matter how much power your engine has, having reliable brakes is crucial to ensure you can stop safely when needed.
If you’re noticing any issues with your braking – whether it’s longer stopping distances, strange noises, or a soft pedal – it’s time to get them checked. Your vehicle’s performance isn’t just about going fast; it’s also about having the power to slow down when it counts.
