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?

Recalls the days when a 396 in a '65 Vette was rated
at 425 hp, exact same engine in a '66 Chevelle was
rated at 375 hp. I'm sure there are many more examples.

Nein,
in the XT5, the engine also scores less power when flipped around.

Is that because the engine is capable of providing N horsepower but the
transaxle is only rated less than that?

Or that the transverse has to have a crossover pipe... maybe resulting in a less efficient exhaust system?

Well maybe for the 9T50 gearbox, which can't handle a lot of torque - might
explain them detuning to limit the maximum torque.
But 2018 Lacrosse gets the 9T60 and still has the slightly weaker engine.
