When Stacy bought his sporty used VW Golf GTI, she couldn’t wait to get it out on the road. It was advertised with 230 brake horsepower (BHP), full service history, and looked immaculate. But within a few weeks, something felt off. Acceleration was sluggish, motorway overtakes were frustrating, and fuel consumption was way higher than expected. Curious, Stacy ran a BHP check – and discovered the car had originally left the factory with just 150 BHP.
The GTI badge was real. But under the bonnet? It was a lower-powered trim with a cosmetic upgrade. Amir had overpaid by nearly £3,000 for performance he’d never get back.
What is BHP and why does it matter?
BHP – or brake horsepower – measures the engine’s power output before losses through the gearbox, wheels, or tyres. It’s one of the most important technical figures in a car’s profile, especially if you’re choosing between trim levels, planning insurance, or comparing performance.
In practical terms:
- BHP affects acceleration, towing ability and top speed
- It’s used by insurers to calculate your premium
- It influences fuel efficiency and engine strain
- It directly impacts a car’s resale value
Getting it wrong – or being misled – can cost you thousands, and leave you stuck with a car that underdelivers.
How do BHP mistakes happen?
It’s more common than you think. Sellers might:
- List the wrong trim level
- Rely on assumptions about engine upgrades
- Copy and paste from other listings
- Use incorrect tuning claims without evidence
- List the peak BHP from a remap that no longer exists
And sometimes it’s not deliberate. A car might have had an engine swap, or simply be misunderstood by the current owner. But in any case, if you’re relying on BHP for performance or insurance – you need to be sure.
Real-world impact of a BHP mistake
Consider this:
- Two Ford Focus models from the same year: one produces 100 BHP, the other 182 BHP
- The higher BHP model might cost £600 more in insurance per year
- And £2,000 more on the used market
If you accidentally buy the lower BHP model thinking it’s the faster version, you’ve lost money on day one. And if you insure the car based on incorrect power – your policy could be invalid.
