Yes guys as flyingspur says it is 987 BHP i.e 1001 PS
Here's the explanation guys:

PS stands for Pferdestärke (literally, 'horse strength'). whereas BHP stands for Brake Horse Power. Both denote power of an engine or car.

PS is a slightly higher figure than the BHP. As a rule of thumb, you can knock off one PS for every 100PS to reach a rough bhp figure. If you want to be completely accurate, multiply the PS figure by 0.9864 to reach the bhp total, or bhp by 1.0139 to get back to PS.

So 1.0139 * 987 BHP = 1000.7 or 1001 PS

Hope this is helpful!

Hi Brabus! While I agree to the conversion, what confuses me is this:

Bugatti Veyron 16.4 Grand Sport-untitled.jpg

The Bugatti Veyron's website clearly states its power to be 1001 Horsepower, and not 1001 PS.

Wikipedia defines Brake Horsepower (and Horsepower) as
Quote:
Brake horsepower

Brake horsepower (bhp) is the measure of an engine's horsepower without the loss in power caused by the gearbox, generator, differential, water pump, and other auxiliary components such as alternator, power steering, and AC compressor. Thus the prefix "brake" refers to where the power is measured: at the engine's output shaft, as on an engine dynamometer. The actual horsepower delivered to the driving wheels is less. An engine would have to be retested to obtain a rating in another system. The term "brake" refers to the original use of a band brake to measure torque during the test (which is multiplied by the engine RPM and a scaling constant to give horsepower).

Source: Horsepower - Wikipedia, the free encyclopedia
The same article says that
Quote:
1 PS = 75 kilopond·metre/second ~= 735.5 newton·m/s ~= 735.5 W ~= 0.7355 kW ~= 0.98632 hp (SAE)
which means 1001HP would be (1001/0.98632)*1 = 1014.884PS

@flyingspur - Please do not take this as me sticking by what I said or arguing my point hard! I just want to clarify what the car's actual power is, because I have been always believing that its power is 1001 HP and it is kind of disappointing if it is less than that

On a side note - if this car is actually delivering 1001 HP (as per the definition from Wikipedia) to the wheels, it means that the engine's BHP is much higher than that - WOW cheers:

I cant imagine 987 bhp in a car...just imagine the revs and acceleration.
Awesome car indeed...another italian marvel.

It is actually more - 1001 HP, see my previous post in this thread

I'm sorry, you're on a forum of car freaks/enthusiasts Bugatti is French, and NOT Italian!
