What is the difference between the BMW M5 and M Performance models?

I'm considering between these two BMW M5 models, but can't seem to find a clear distinction. Can you help me understand the technical differences?

The BMW M5 is the standard model with a 4.4-liter V8 engine and 600 horsepower, while the M Performance model has a 4.4-liter V8 engine with 617 horsepower. This may not seem like a big difference, but the M Performance model also has a stiffer suspension and increased performance components, making it a more track-focused vehicle.

From a design perspective, the M5 has a more subtle and understated look while the M Performance model has more aggressive styling with carbon fiber accents. It ultimately comes down to personal preference and what you value more - performance or aesthetics.
