The Porsche 928 was a grand touring coupe produced by the German automotive manufacturer Porsche from 1977 to 1995. It was designed to replace the Porsche 911 as the company's flagship model, and although it ultimately did not completely supplant the 911, it achieved significant success in its own right. The 928 featured a revolutionary front-mounted V8 engine, a departure from the traditional rear-mounted flat-six engine used in the 911. This innovative layout offered a more balanced weight distribution, leading to improved handling and stability. The 928 was also one of the first production cars to feature a transaxle, a gearbox integrated with the rear differential, allowing for even weight distribution between the front and rear axles.

The 928's sleek and aerodynamic design, coupled with its powerful engine and advanced technology, established it as a high-performance luxury car. The car was praised for its comfortable interior, luxurious amenities, and refined ride, making it a capable and enjoyable grand tourer. Over its production run, the 928 underwent several updates and revisions, including different engine options, transmissions, and styling changes. It was a technologically advanced car for its time, featuring features such as power steering, air conditioning, and an advanced suspension system. Despite its technological innovations and performance capabilities, the 928 struggled to achieve the same level of cultural icon status as the 911. However, it remains a highly sought-after classic car by collectors and enthusiasts, appreciated for its unique engineering, performance, and style.
