The Porsche 928 S, a grand tourer produced from 1983 to 1985, marked a significant evolution of the original 928 model. It represented a blend of performance, luxury, and innovative engineering that solidified Porsche's presence in the high-end automotive market. The 928 S benefited from several significant upgrades over its predecessor, including a more powerful 4.5-liter V8 engine that delivered 237 horsepower, a revised suspension system for improved handling, and a redesigned interior with enhanced comfort and refinement. Notably, the 928 S was the first model to feature Porsche's optional automatic transmission, offering drivers a more relaxed driving experience. This combination of power, comfort, and technological advancements made the 928 S a highly sought-after automobile, attracting both enthusiasts and discerning drivers seeking a blend of performance and luxury.

Despite its success, the 928 S faced challenges in the market due to its relatively high price point and the changing preferences of consumers at the time. The emergence of powerful, yet more affordable, sports cars, along with the continued popularity of the Porsche 911, contributed to a decline in 928 sales. However, the 928 S remains an important historical figure in the evolution of Porsche, representing a bold departure from the traditional 911 formula and highlighting the brand's commitment to innovation and performance. It also serves as a reminder of the era when grand touring cars combined luxurious amenities with impressive driving dynamics, attracting a dedicated following among enthusiasts and collectors alike.
