The Porsche 928 S, a luxurious grand tourer produced from 1977 to 1995, represents a bold departure from the traditional Porsche sports car formula. The 928, initially envisioned as a successor to the iconic 911, boasted a unique front-engine, rear-wheel-drive layout, a stark contrast to the 911's rear-engine configuration. The "S" model, introduced in 1980, marked a significant step forward in both performance and refinement. It featured a larger, 4.7-liter version of the 928's signature V8 engine, producing a considerable 237 horsepower. This powerplant, coupled with a 5-speed manual transmission or a sophisticated 4-speed automatic, propelled the 928 S to impressive speeds, making it a formidable performer on both road and track. Beyond its performance capabilities, the 928 S offered a level of comfort and luxury rarely found in sports cars of the era. Its spacious interior featured plush leather upholstery, power-adjustable seats, and an array of modern conveniences.

The 928 S attracted a loyal following, establishing itself as a compelling and innovative alternative to the 911. However, its larger size and more luxurious nature did not entirely resonate with the traditional Porsche clientele. Nonetheless, the 928 S carved a distinctive niche for itself within the automotive landscape, becoming a symbol of sophisticated performance and timeless design. The wiring diagram for this model, a comprehensive blueprint of its electrical system, provides invaluable insight into the intricate workings of this technological marvel. Its detailed schematics reveal the complex network of wires, connectors, and components that bring the 928 S to life. Understanding these intricate details is essential for those seeking to maintain, repair, or modify this iconic Porsche.
