XM superhybrid proved to be much more powerful than BMW claimed

The American YouTube channel IND Distribution tested the Bavarian hybrid on a dyno and got unexpected results. On the wheels, we managed to get a peak output of 623 horsepower and a torque of 771 Nm, that is, taking into account the transmission losses of an all-wheel drive car, the real power of the BMW XM was 779 horsepower and a torque of 965 Nm!

The IND Distribution team mentioned that the readings are influenced by atmospheric conditions, the settings of the stand itself, as well as measurement techniques. Doubting the results of the first test, the crossover was tested again to minimize the likelihood of errors. In subsequent measurements, the XM developed about 725 horsepower and 875 Nm of torque.

Bloggers honestly admitted that a car with not fully charged batteries was driven onto the dyno. Another factor is the hybrid power plant, which is configured in a special way, which can also make adjustments to the measurements. Finally, BMW XM transmission losses can be less than 20 percent. And yet, the new crossover is clearly more powerful than the declared one, because the plant guarantees only 653 horsepower and 800 Nm of torque.

The underestimation of emoks is becoming a hallmark of BMW: last time, IND Distribution bloggers tried to find out the power of the M5 F90, and came to the conclusion that the V8 engine produces about 700 horsepower from the factory instead of the claimed 600.
