The Porsche 928 is a grand tourer (GT) that was produced by Porsche from 1977 to 1995. It was designed to replace the iconic 911 as Porsche’s flagship model, though it ultimately co-existed alongside the 911 for much of its production run. The 928 was a significant departure from the 911 in terms of its design and engineering. It featured a front-mounted V8 engine, a transaxle gearbox, and a luxurious interior. The 928 was praised for its comfortable ride, its powerful engine, and its stylish design. It was also one of the first cars to feature a "water-cooled" engine instead of the traditional air-cooled engine that was found in the 911. The 928 saw several iterations throughout its production lifespan, with the "S" model adding a fuel-injected 4.5-liter V8 engine and improved suspension, the "S4" model boasting a 5.0-liter V8, automatic transmission, and electronic engine management, and the "GT" model featuring a wider body, a larger rear spoiler, and a more powerful engine. The "GTS," the final iteration of the 928, was a high-performance version of the car that featured a powerful 5.4-liter V8 engine and a sporty interior. Despite its revolutionary features and critical acclaim, the 928 never quite achieved the same level of success as the 911. It was a more expensive car to produce and maintain than the 911, and its front-engine layout was not as popular with enthusiasts as the 911’s rear-engine layout. Nonetheless, the 928 remains a significant and influential car, and it is still highly sought after by collectors today. Its unique blend of luxury, performance, and design helped to shape the future of the GT car genre, and it continues to inspire automotive enthusiasts around the world.
