What does 400 brake horsepower mean

Question

and what is Brake horsepower

Answer 1

It gives you an idea of how powerful the car is. For example, a bog standard Vauxhall Vectra with a diesel engine will have around 120 bhp, where a performance car such as a BMW M5 has 507 bhp.

400 bhp is alot, you are looking at M3 / RS4 performance there.

However torque is basically the overtaking power of a car. Diesel's have more torque than petrol powered cars, so the mid range acceleration (e.g. 60 - 90 mph) will be far quicker.

Hope this helps you a bit :)

Answer 2

Brake horse power is the power of an engine as measured by applying a brake to the output shaft and measuring the energy absorbed by the brake. one horse power is the equivalent work performed by a single horse and equates to 550 foot pounds force per second. This is nowadays more usually stated in the metric system as 745.7 watts. So, 400 BHP is 400 times this value.

Answer 3

It the equal power to a horse. Due to horses being the main transport for centuries. The first cars made, their power was in horsepower to make it simpler for people to understand. 400 brake horsepower (BHP) has the equal power to 400 horses.  

Answer 4

Usually two different labels for horsepower on a car -- Brake horsepower, and Wheel horsepower -- BHP is the power from the flywheel of the engine.   WHP is the power that's actually being put down, after the transmission loss, drivetrain loss, etc....   my van puts out 230BHP, but after the transmission, driveshaft, differential, etc... about 170WHP is actually being put to the ground.

Answer 5

When cars were first mass produced the power of the car was explained as horse power. This was to give the customer an idea of how power-full the car was.
