The Porsche 928, produced from 1978 to 1995, was a grand tourer that represented a significant departure from the traditional Porsche sports car formula. It offered a front-engined layout, unlike the rear-engined 911, and was designed to be a luxurious and comfortable grand touring car. The 928 was a technological marvel for its time, featuring a powerful V8 engine, a sophisticated suspension system, and a luxurious interior. Its distinctive design, with its sloping hood and retractable headlights, made it instantly recognizable. The 928 was initially intended to replace the 911 as Porsche's flagship model, but it eventually became a successful niche vehicle, recognized for its unique blend of performance and comfort. The 928's engine was a 4.5-liter V8 initially, later growing to a 5.0-liter and finally a 5.4-liter, producing impressive power and torque. This powerful engine was paired with a 5-speed manual or a 4-speed automatic transmission. The car's handling was praised for its balance and composure, thanks to its sophisticated suspension system and its front-engine, rear-wheel drive configuration. Over its production run, the 928 received several updates and refinements, including increased engine power, improved aerodynamics, and enhanced interior features. Despite its impressive performance and luxury, the 928 never achieved the same level of iconic status as the 911. This was likely due to its higher price point and its initial positioning as a potential replacement for the 911, which was already a beloved and highly successful model. However, the 928 carved out its own niche in the automotive landscape, becoming a sought-after collectible known for its unique blend of performance, luxury, and style.
