The Porsche 928, a grand tourer produced from 1978 to 1995, represents a fascinating departure from the traditional Porsche sports car formula. While the iconic 911 maintained its rear-engine layout, the 928, designed as a potential successor, employed a front-engine, rear-wheel drive configuration. This innovative approach aimed to address concerns around the 911's inherently challenging handling characteristics and to offer a more luxurious and comfortable driving experience. The 928 is renowned for its striking design, featuring a low-slung profile, sweeping lines, and a distinctive pop-up headlight configuration. The spacious interior, with its luxurious appointments and advanced technology for its time, further emphasized the car's grand touring nature. Underneath its elegant exterior, the 928 concealed a potent powerplant: a 4.5-liter V8 engine, initially developing 240 horsepower, later escalating to 316 horsepower in the S model. This engine, coupled with a sophisticated transaxle transmission, delivered exhilarating performance and a refined driving experience. Over its production run, various iterations of the 928 were introduced, including the 928 S, 928 S4, and 928 GTS, with each iteration incorporating mechanical and cosmetic upgrades. Despite its innovative design and impressive performance, the 928 never quite achieved the iconic status of its 911 sibling. Nevertheless, it has earned a dedicated following among enthusiasts who appreciate its unique character, luxurious amenities, and powerful performance. Today, the Porsche 928 remains a highly sought-after classic, considered by many to be a true masterpiece of automotive engineering.
