Why is the Mercedes E-Class known as the "baby S-Class"?

I've heard people refer to the Mercedes E-Class as the "baby S-Class" but I'm not sure why. Can someone explain the connection between these two models?

The Mercedes E-Class has often been called the "baby S-Class" because it shares similar design elements and technology with its bigger and more expensive counterpart, the S-Class. This makes it a more affordable option for those who want a taste of the luxury and performance of the S-Class.

The S-Class is known as the flagship model for Mercedes-Benz, setting the standard for luxury and innovation. The E-Class takes many of those qualities and puts them into a smaller and more affordable package, giving drivers a taste of the S-Class experience without the high price tag.

As the E-Class has evolved over the years, it has gotten closer and closer to the level of luxury and technology found in the S-Class. This has earned it the nickname of "baby S-Class", as it offers a similar driving experience but at a lower price point.
