History of the Porsche 928
Porsche released the Porsche 928 luxury grand tourer in 1978, it remained in production until 1995. The 928 was developed to supplant the company's legendary 911, combining the power, poise, and handling of a sports car with the elegance, comfort, and amenities of a luxury sedan. Porsche's top-of-the-line production automobile became the 928. The 928 was the company's first production V8-powered vehicle, as well as Porsche's first coupé driven by a front-mounted V8 engine.
The 928 was powered by a massive water-cooled V8 engine that drove the rear wheels. It was originally rated at 219 horsepower for the North American market and 237 hp for foreign markets, with a displacement of 4.5 L and a single overhead camshaft design.
