LGX engine power output query
This new motor is specced at 250 kW when mounted north-south in a Cadillac.
But when mounted east west, it is only 231 kW in Buick or 235 kW in Opel. So what is the difference? Does the transverse installation cramp the exhaust and air intake, or did Cadillac just get a hot engine map? |

Let me guess, one car is sold in Europe and one is sold in the US and they have two methods for measuring BHP? --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

I'm sure there are many more examples. |

Is that because the engine is capable of providing N horsepower but the transaxle is only rated less than that? --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

But 2018 Lacrosse gets the 9T60 and still has the slightly weaker engine. |
