Ever wondered how powerful your car really is? A car BHP check helps you find out your car’s engine power, torque, and performance using just the number plate. Whether you’re buying a used car, comparing models, or just curious about your car’s power, this check gives you quick and useful results. BHP tells you how much power the engine can produce, but other things like torque, weight, and tuning also affect how the car drives.
To better understand what BHP means and how it’s different from horsepower or other terms like PS and kW, let’s break it down in simple terms.

Why car bhp matters when buying a used car?
When you’re buying a used car, it’s easy to get caught up in mileage, price, or the condition of the bodywork. But there’s one figure many buyers overlook — BHP.
Here’s why checking a car’s BHP can help you make a smarter buying decision:
🔸 Helps compare similar models
Two cars might look the same but have very different engines. A quick car BHP check shows you how powerful each version is, so you don’t end up paying more for less performance.
For example, a Ford Fiesta might come with both 95 BHP and 125 BHP versions — and the difference in real-world driving is noticeable.
🔸 Reveals towing or load capability
Planning to tow a trailer or carry heavy loads? A car with higher BHP and torque will handle the job better. This is especially important for buyers looking at SUVs, vans, or estate cars.
🔸 Affects insurance and running costs
Cars with higher BHP can sometimes mean higher insurance premiums, especially for young or new drivers. A BHP check helps you weigh up the cost of performance before buying.
🔸 Useful for ev vs petrol comparisons
Used EVs often come with strong performance figures — even small models have surprising power thanks to instant torque. If you’re comparing a used petrol car with an electric one, checking the BHP (or kW) gives you a fair comparison.
🔸 Shows true driving experience
BHP affects how a car feels on the road — from acceleration to overtaking. If you test drive two used cars and one feels more responsive, it’s often because it has more power under the bonnet.
Understanding Car Power: BHP, HP, PS, and KW explained
When you’re comparing cars — especially used ones — you’ll come across terms like BHP, horsepower, PS, and kW. They all relate to engine power, but they’re not quite the same. Understanding the difference helps you make a smarter choice, especially if you’re stuck between two versions of the same model.
Let’s explain each one in simple words, with real examples.
What is BHP?
BHP stands for Brake Horsepower, and it’s the most commonly used measure of engine power in the UK. It tells you how much power the engine produces before mechanical losses like friction in the gearbox, drivetrain, and alternator are taken into account.
Think of it as the raw output of your engine, before that power gets sent to the wheels.
So, if a Ford Fiesta 1.0 EcoBoost has 125 BHP, that’s the clean figure of how much energy the engine produces at the crankshaft — ideal for comparing engine variants when buying used.
What does PS Mean?
PS comes from the German term Pferdestärke, which translates to “horse strength.” It’s used by many European manufacturers — so if you’ve seen specs for Audi, BMW, Mercedes, or Volkswagen, you’ve probably seen PS ratings.
PS is almost the same as horsepower, but a little bit lower. For example:
- A car listed with 100 PS has about 98.6 HP.
It’s close enough that most drivers won’t notice a difference — but if you’re comparing two similar models, it’s good to know they’re not identical.
What are Kilowatts (kW)?
Kilowatts (kW) are the metric unit of engine power, and they’re becoming more common with electric vehicles (EVs). Manufacturers often quote EV power in kW, but many UK drivers still prefer BHP or HP because they’re more familiar.
To help you visualise it:
- A Tesla Model 3 Standard Range has a motor rated at around 190 kW, which equals about 255 BHP.
- A Vauxhall Corsa Electric offers around 100 kW, or 134 BHP.
If you’re switching to an EV, don’t worry — you can always convert kW to BHP by multiplying by 1.341. Most spec sheets now show both figures to make it easier.

| Term | Meaning | Used By | Conversion |
|---|---|---|---|
| BHP | Brake horsepower | UK drivers & tuners | 1 BHP ≈ 1.0139 HP |
| HP | General horsepower | US/Global | 1 HP = 0.986 BHP |
| kW | Kilowatts | EVs & official docs | 1 kW = 1.341 HP / 1.3596 PS |
| PS | Metric horsepower (Pferdestärke) | EU car makers | 1 PS = 0.986 HP |
Is checking a car’s BHP enough to know its full performance?
No, it is not. While BHP tells you how powerful the engine is, a car’s full performance also depends on things like torque, weight, aerodynamics, body size, and fuel type.
A full car speck check can give you a better view of how the car will handle in different driving conditions — whether you’re driving in the city, towing, or going off-road. Our full car report includes key details like engine size, fuel type, number of gears, torque, top speed, and more — so you can choose a car that fits your needs and lifestyle.
Exploring additional factors - torque, weight, and aerodynamics:
When assessing a car’s performance, it’s important to look beyond BHP and consider other key factors:
Torque: Torque is the engine’s rotational force, crucial for acceleration, towing, and overtaking. Higher torque ensures better off-the-line performance and drivability. It varies with engine types like turbocharged or diesel.
Weight: A lighter car accelerates faster, handles better, and uses less fuel, while heavier cars offer stability but may compromise agility. Weight distribution also affects handling.
Aerodynamics: Good aerodynamics reduce drag, improving fuel efficiency, top speed, and stability. Features like sleek designs and spoilers enhance performance, especially at high speeds.
Other performance factors to consider might include the following:
- Transmission: The type of transmission (manual, automatic, dual-clutch, etc.) and its gear ratios can impact acceleration, responsiveness, and fuel efficiency.
- Suspension: The suspension system affects ride quality, handling, and cornering abilities. Options like adaptive suspension or sport-tuned suspension can enhance performance characteristics.
- Tires and Grip: The quality, size, and type of tires can significantly impact a car’s grip, handling, and braking capabilities.
- Power-to-Weight Ratio: Calculating the power-to-weight ratio (BHP per kilogram or pound) can provide a relative measure of a car’s performance potential.
By considering these additional performance factors alongside BHP, you can better understand a vehicle’s performance capabilities and make informed decisions based on your specific needs and preferences.
Can I measure BHP in electric cars like petrol or diesel?
Not exactly. BHP is based on how much power an engine makes at high revs — which applies more to petrol and diesel cars. Electric cars don’t need to rev up to deliver full power; they give instant torque from a standstill.
That’s why even lower BHP EVs can feel faster than more powerful petrol models. It’s not a straight comparison, but EVs are often quicker off the line.

What other aspect influences a car’s overall performance?
Other things could also have an impact on the performance of your vehicle. These features include the,
• The kind of fuel the car needs is crucial to know which kind of fuel is ideal for your vehicle.
• The car’s gear ratio will enable you to understand how the vehicle acts at various speeds.
• You can estimate how long the automobile will last between fuel stops by looking at the size of the engine and the gasoline tank.

Frequently asked questions
You can check your car’s BHP by entering the registration number into the CarAnalytics BHP checker. It pulls data from trusted DVLA records to show your car’s engine power, torque, and other performance specs instantly.
Most average UK cars have a BHP between 90 and 150. Higher BHP means more power, but what’s best depends on how and where you drive.
Not always. BHP affects speed and acceleration, but weight, aerodynamics, and torque also play big roles in how fast a car feels on the road.
BHP and horsepower are similar, but BHP is a more accurate measure as it excludes energy lost to friction. In everyday use, they’re often treated the same.
