The Porsche 928 is a grand touring car that was produced by Porsche from 1977 to 1995. It was designed to replace the 911 as Porsche's flagship model, and it was the first front-engined Porsche to be offered with an automatic transmission. The 928 was initially met with mixed reactions, but it eventually gained a reputation for its powerful engine, luxurious interior, and sporty handling. It featured a front-mounted V8 engine, a transaxle layout (with the transmission mounted at the rear axle), and a sophisticated suspension system. It was available in a variety of body styles, including a coupe, a convertible, and a limited edition S model. The 928 was a technological marvel for its time, featuring features like a digital instrument cluster, power windows, and a sunroof. Despite its innovation and performance, the 928 met with less commercial success than the iconic 911. This was due in part to its higher price point and the fact that it was seen as a departure from Porsche's traditional rear-engine layout. It also struggled to compete with the powerful and luxurious Mercedes-Benz S-Class, which was a strong competitor in the high-end grand touring car market. However, the 928 has since gained a cult following, and it is now considered a classic and highly collectible car. Many enthusiasts appreciate its sleek and sophisticated design, its potent engine, and its impressive handling capabilities. The 928 also stands as a testament to Porsche's engineering prowess and its commitment to innovation.
