What are the differences between the Audi e-Tron 55 and 50 models?

I am new to electric cars and considering buying an e-Tron. I have seen that there are two versions - 55 and 50. What are the main differences between the two models?

The main difference between the Audi e-Tron 55 and 50 models is their battery size. The e-Tron 55 has a larger battery and therefore a longer driving range.

Another difference is the power output of the motors. The e-Tron 55 has a higher power output, resulting in faster acceleration and better performance.
