The Porsche 928, a grand tourer produced from 1978 to 1995, marked a significant departure from the traditional air-cooled, rear-engined layout of its predecessors. This two-door, 2+2 seater coupe, designed by Wolfgang Möbius, featured a front-mounted, water-cooled V8 engine that drove the rear wheels through a transaxle. The 928 was conceived as a potential successor to the iconic 911, offering a more spacious and comfortable driving experience with a powerful and sophisticated powertrain. Its unique design, with its distinctive sloping nose, sleek profile, and retractable headlights, garnered attention and admiration. The 928 was initially available with a 4.5-liter V8 engine producing 240 horsepower, but over the years, engine displacement and power outputs increased, culminating in the 5.4-liter, 345 horsepower engine found in the final 1995 model. Beyond its powerful engine, the 928 was a technologically advanced car for its time. It featured a sophisticated suspension system, including a rear-mounted multilink setup, a complex but effective brake system, and an array of interior amenities. The 928 was praised for its smooth and refined driving experience, its comfortable and well-appointed interior, and its impressive performance. Despite its intended role as a successor to the 911, the 928 never quite achieved the same iconic status. However, it has gained a devoted following over the years for its distinctive design, impressive performance, and unique engineering. A 1978-1994 Porsche 928 Workshop Service Repair Manual provides invaluable support to owners and mechanics seeking to maintain and repair these iconic vehicles.
