A lie
A random number between the gross horsepower and the actual brake horsepower
Frigon_P has it exactly wrong, nice job.
BHP is the horsepower at the wheel, after all accessories and driveline losses. Gross HP is what frigon was talking about. Back in the Muscle Car days the manufacturers quoted gross, until the numbers got so big that the insurance companies started freaking out, then they would just make something up. Then in the 70s they started using SAE net, which included accessories such as water and oil pump, but not driveline losses. For a long time Porsche was the only company that actually quoted true BHP (hence the 205 BHP 911 was substantially faster than the 225 ?hp mustang), but even they have wandered somewhat. Now car manufacturers and advertorials, er I mean car magazines, all say BHP but it's not. For instance, the 290"bhp" NSX is actually putting down about 220 HP at the wheel. The amount that the manufacturer lies varies by Asianess of the vehicle.
---In fairness to Frigon it is wrong on Wiki as well.

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 auxiliaries. 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.
