Zitat von midlife crisis im Beitrag #15Zitat von Ali-bear im Beitrag #14 Not quite..... 1 pferdestarkes (PS) = 0.7355 kW 1 HP = 0.7457 kW So, 1HP = 1.0139 PS But, in polite company, quantities like pferdestarkes (PS) or Kilopond (kilogram force) should be treated in the same manner as using the f-word in church. Never, ever. Old Forum Orphan |

Zitat von Ali-bear im Beitrag #17 From what I can tell........1 PS = 75kgf at a velocity of 1 meter / sec was someones estimate of 1 horsepower. Since 1 Kgf or Kilopond = 9.807 N (newtons), 1PS = 735.5 N-m/s = 735.5 W = 0.7355 kW. Or, so I think. Thus, you can understand my prior caution about using these "unit-confused" numbers. It's the same tale of woe as when someone mentions lbs-mass, lbs-force and slugs. Most engineers just cringe and look for the bathroom. Old Forum Orphan |

Zitat von Ali-bear im Beitrag #17 See https://en.wikipedia.org/wiki/Horsepower#Definitions There are many versions of horsepower depending on what constants you use in terms of weight, distance and time. The RAC invented one to lower a vehicle's HP rating as a tax dodge. All predate the notion of a united Europe. Even the International Organization for Standardization has recognised seven methods to calculate HP. |

Been to pay for my forthcoming R1250rs at my local dealer and looking at the BMW 2020 range catalogue, quoted BHP 136!! |

The Europeaan certificate of conformity mentions 136 BHP. I assume with standard exhaust. But I think that COC for vehicle delivered ex factory with Akrapovic exhaust will mention the same. The COC does not get adjusted for "options" added to vehicle.

It has the power that it has, simples. |

The 2 Bhp is not the question! |
