Porsche 928: generations, V8 engine and what to know before buying
The Porsche 928 is a luxurious grand tourer with a front-mounted V8 engine, produced from 1977 to 1995. We look at the generations, engines, and what to check when buying a classic 928.
Porsche 928 in brief
The Porsche 928 was designed as a comfortable and fast grand tourer, not purely a sports car. It features a front-mounted V8 engine, rear-mounted transmission, and a 2+2 seating arrangement. In 1978, the 928 was named European Car of the Year.
Today, the 928 is valued for its distinctive design, comfort, and powerful V8. It's a rare find in the used market, often appealing to enthusiasts and collectors.
Which version to choose
Throughout its production run, the engine was continually strengthened and refined. Early 928s had a 4.5-litre V8, the 928 S a 4.7-litre, and the S4, GT, and GTS models 5.0 and 5.4-litre engines.
Later versions—the S4, GT, and especially the GTS—are considered the most desirable: they are more powerful, modern, and better equipped, but are rarer and more expensive.
Engines and transmissions
All engines are aluminium V8s. Power ranged from around 240 hp in the earliest versions to about 350 hp in the GTS model. These are robust, smooth engines, but they are thirsty.
The transmission is a 5-speed manual or automatic. Most cars have the automatic, which is very well-suited to this model for comfort.
What to check when buying a Porsche 928
The most important thing is the service history of the engine, especially the timing belt replacement. Neglecting this can result in a very expensive repair. Also, check the cooling system, oil leaks, and the gearbox.
Inspect the body, suspension, brakes, and electrical equipment — air conditioning, windows, headlight lift mechanism. A classic Porsche requires specialized parts and mechanics.
