This model represents a departure from the classic Porsche 911, showcasing a front-engined, rear-wheel-drive layout that proved to be a game-changer in the automotive world.

Notably, it received a power boost with a larger, 4.7-liter V8 engine capable of producing a remarkable 237 horsepower.

Beyond its compelling powertrain, the 928 S offered a refined driving experience, thanks to its advanced suspension system, power-assisted steering, and four-wheel disc brakes. The interior, designed with meticulous attention to detail, provided a luxurious and comfortable setting for both driver and passengers. Leather upholstery, wood trim, and a comprehensive array of amenities, including air conditioning, power windows, and a stereo system, elevated the 928 S to a level of sophistication that was uncommon for sports cars of the time. Its striking design, featuring sleek lines, a distinctive sloping roofline, and pop-up headlights, made the 928 S a true head-turner, solidifying its status as a symbol of elegance and performance.
