Models with the E23 body index became the first BMW of the 7 series and continued the ideology of the executive class, launched by the 3.0L-3.3L models in the E3 body.

The competition in the executive class in those years came down to the rivalry with the Mercedes-Benz S-class in the back of the W116. Debuting with three BMW 7 Series models (728, 730 and 733i) in May 1977, the Bavarians were doomed to success.

High level of comfort, smoothness and at the same time good handling became additional trump cards in the BMW deck in the game with Mercedes-Benz.

The ever-increasing waiting times for the already aging Mercedes W116 model have given BMW 7 a chance to win new customers.
