This generation of the 7 Series was the first to use the E23 platform, a revolutionary design that introduced a host of innovative features and technologies. The E23 was built on a longer wheelbase than its predecessor, the E3, providing ample interior space and comfort for its occupants. It offered a range of powerful engine options, including the iconic M70, a 5.0-liter V12 engine that delivered a thrilling driving experience. Additionally, the E23 introduced features such as power steering, air conditioning, and a sophisticated sound system, all of which were considered luxurious for the time. However, the real highlight of the E23 was its advanced technology. It was one of the first cars in the world to feature a digital instrument cluster, a groundbreaking feature that allowed drivers to access a wealth of information about their vehicle. The E23 was also one of the first cars to offer a fully-fledged onboard computer, which could diagnose potential issues and provide maintenance reminders. This pioneering technology solidified the 7 Series' reputation as a technological marvel and a true luxury sedan. While the E23 was a massive success for BMW, it was not without its challenges. Many owners complained about the car's complex electronics and the high cost of maintenance. However, despite these drawbacks, the E23 remains a highly sought-after classic today. Its sleek design, powerful engines, and advanced technology have made it a timeless icon in the world of luxury automobiles. The E23 cemented BMW's position as a leader in the luxury car segment and set the stage for the incredible success that the 7 Series would enjoy in the decades to come.
