Free BHP check
Our FREE BHP check tool can tell you the brake horsepower (BHP) of any UK-registered vehicle.
Simply enter the reg number of the vehicle you want to check to get started!
How does the brake horsepower check tool work?
Our BHP check tool refers to vehicle specification data to confirm the brake horsepower (BHP) of UK-registered vehicles by reg number.
How do I check the brake horsepower of my car?
The simplest way to check your car’s BHP is to enter its registration number into our free BHP check tool. (This should work for all UK-registered vehicles.
Alternatively, check the statistics for the relevant car model on the manufacturer’s website. If the manufacturer cites the engine power in a different metric such as horsepower (PS) or kilowatts (kW), you can use our free car power converter tool to convert this measurement into BHP.
BHP and electric vehicles
Just like the combustion engine in a petrol or diesel car, an electric car’s motor produces power that sets its wheels in motion. Brake horsepower can be used to measure the power input of both internal combustion engines and electric motors.
However, an electric motor delivers power to the wheels in a different way. In many electric cars, the motor is fitted where the engine would sit in a combustion engine model. The electric motor transfers power to the wheels through a drive shaft.
Different types of electric motors or combustion engines can produce varying levels of power at a certain horsepower rating. For example, an electric motor may provide more torque than an internal combustion engine with the same horsepower.
If you are considering whether to buy an electric car, brake horsepower ratings will give you a good indication as to how quickly each model can accelerate - and how much torque they have available to travel uphill and overtake other vehicles.
Just as with combustion engine cars, the higher the brake horsepower an electric vehicle has, the more powerful it is.
You might see an electric car’s power cited in the horsepower (PS) or kilowatts (kW) metrics. If you are curious to see the brake horsepower (BHP) for a specific model, try using our car power converter.
Frequently asked questions
Brake horsepower (BHP) is a measurement of engine power.
BHP refers to a car’s horsepower (PS) minus the power lost from friction between its tyres and the road.

BHP is measured using a brake dynamometer in a specific location (e.g. the crankshaft, rear axle, rear wheels or the transmission’s output shaft).
Unlike horsepower, BHP takes frictional power loss into account – and therefore BHP is always slightly lower than horsepower.
Horsepower (PS), BHP and kilowatts (kW) are all commonly used measurements of engine power. Here is a quick guide to how they each are calculated:
- Horsepower (PS) is an imperial unit of power referring to the power required to move 550 pounds one foot in one second (or to move 33,000 pounds one foot in one minute). It measures how much power is sent to the wheels (including any power that is lost from friction).
- Brake horsepower (BHP) refers to how much ‘useful’ power an engine can deliver (which excludes any power that is lost to friction). The formula for calculating BHP is: Torque x RPM (Revolutions per minute) ÷ 5,252.
- Kilowatts (kW) is a measurement of power that can be calculated with the following formula: Torque x RPM ÷ 9.5488.
