The Porsche 928, produced from 1978 to 1995, was a grand tourer that marked a significant departure from the traditional rear-engined Porsche sports car layout. Instead of the air-cooled flat-six engine found in the 911, the 928 boasted a front-mounted, water-cooled 4.5-liter V8, coupled with a transaxle transmission. This configuration, intended to provide a more comfortable and practical grand tourer, was initially met with some resistance from purists. However, the 928's performance, handling, and luxury features quickly won over many. It was even named "Car of the Year" by Motor Trend magazine in 1978, a testament to its innovation and capability. The 1981-1982 928 and 1980-1984 928 S models represent a significant evolution in the car's development. These iterations featured a larger 4.7-liter V8 engine, producing a substantial increase in power output. The 928 S, introduced in 1980, further enhanced this performance with a higher compression ratio, revised camshafts, and a larger intake manifold. Both models also benefited from improved suspension tuning, revised brakes, and a more refined interior. These enhancements ensured the 928 remained at the forefront of the grand tourer market, offering a thrilling driving experience combined with luxurious comfort and practicality. The 928's distinctive design, with its sloping front end, wide body, and distinctive pop-up headlights, continues to capture the imagination of car enthusiasts, cementing its place as a significant and iconic model in Porsche's rich history.
