Why does the BMW M5 have a higher horsepower than other models?

I've noticed that the BMW M5 has a higher horsepower than other models in the same category. Can you explain why this is?

The BMW M5 has a higher horsepower because it is equipped with a more powerful engine compared to other models in its category. This allows for a more dynamic and responsive driving experience.

BMW prioritizes performance in their M series models, so they have upgraded the engine in the M5 to give it a higher horsepower. This makes it stand out from other models in its category.
