Though the E3 had offered a sizeable sedan, the replacement E23 really stretched BMW’s platforms. The new 7-seres was 6 inches longer overall, most of which fell in a longer wheelbase versus the E3. It was also wider by a few inches and lower, too. Paul Bracq again provided the styling and it was nothing surprising; it carried the torch of many of the design elements of the 3-, 5- and 6-series cars, and that certainly wasn’t a bad thing. But what BMW hoped would help to set it apart from the competition was technology and performance, along with a high-level of material quality in the cabin. Options included Buffalo leather, an on-board computer system, anti-lock brakes, heated and reclining power seats front and rear, and even an airbag late in the run; standard fare today, but way ahead of the curve in the late 1970s and early 1980s.
