One of the highlights that makes the 928 a famous collectible is that it became a top-of-the-line coupe from Porsche. It was designed by Wolfgang Mobius and Anatole Lapine. The car was meant to be a flagship and appeal better than the 911. The 928 is the first car from Porsche with a V8 engine and also the only coupe with a V8 engine in the front.

The 928 is the only luxury grand tourer that has been released by Porsche to date, but it was released in different configurations like the GTS, GT, S4 and more. Aside from the base model, Porsche offered the S variant, later called the 928 S4. Then there were the CS or Club Sport and GT versions, and the final models were GTS models.

The 928 was not as popular as the 911, but it is currently considered a classic because of its unique style and engine power. There were different changes to the model, including the engine and drivetrains, optional features and packaging, suspension and minor body additions. There were 60,870 units made.

History of the Porsche 928

The Porsche 928 started as a development project in 1971 and was designed to eventually replace the 911 by Porsche. The company had gone through a lot of turmoil during the 70s due to the oil crisis, and it experienced different changes like new executives. The new executive believed that the future of Porsche should be with grand tourers, so he placed a lot of importance on the 928 as a successor of the 911.


But not all leaders agreed, which is why 911 remained a significant part of the car portfolio. The Porsche 918 was first released at the 1977 Geneva Motor Show, and it was then named the Car of the Year by 1978. It was the first time that a sports car won this award.

History of Porsche 928

The car was designed by Anatole Lapine and came with different innovations, like the hatchback body with aluminum doors, front wings and bonnet with lightweight features. The bumpers were also hidden behind the nose and tail sections made of plastic. If you experience a minor collision with your car, the panel will go back into shape.

One innovation is the Weissach axle, which is a unique design of the semi-trailing arm suspension design. The 928 was a great success, and it was able to capture North American sales. But the production stopped in 1995, and the 928 never replaced the 911 as it was intended. The Porsche traditionalists preferred the 911 model.

Features, Design, and Specifications of the Porsche 928

There are different features of the Porsche 928, as the focus of the car when it was released in 1978 was on lightweight construction. Parts of the car were made of aluminum, while the body shape was plastic bumpers. It had round pop-up headlights that were electrically operated and integrated into the wings.

The large window of the rear lid came with a rounded fastback. The 928 models came with a water-cooled V8 engine with a 90-degree cylinder arrangement, and it was transmitted based on the transaxle principle. There were some changes to the 928 as the years went on.

  • Engine Power

There were different engines used in the Porsche 928. These options include 4.5-liter V8, 4.7-liter V8, 5.0-liter V8 and 5.4-liter V8. This came with three types of transmission, which were 5-speed manual, 3-speed automatic and 4-speed automatic transmission. The 4.5-liter engine offered 219 horsepower.

The large, front-mounted and water-cooled V8 engine power the rear wheels. By 1980 in the US, Porsche had moved from a mechanical to an electronic fuel injection system. The transmission was either a five-speed dog leg manual transmission three-speed automatic transmission from Mercedes Benz.

Most of the early 928s came with a cheaper 5-speed manual gearbox as standard, while the optional engine was the 3-speed automatic. Eventually, more cars came with automatic than manual transmissions.

  • Styling and Design

The Porsche model came with a 50/50 front/rear weight distribution using a transaxle, and this contributed to the balance. The weight balance and high power output gave the 928 great performance on the track, and it was even considered a relaxing car to drive.

The car was mostly styled with galvanized steel, while other parts were made of aluminum to save weight. The sports coupe came with a spacious luggage area that could be accessed through a large hatchback. Polyurethane elastic bumpers were added to the nose and tail and covered in plastic, although this reduced its drag.

Also, the car had pop-up headlamps integrated into the front wings. Other features included the Weissach Axle, which increased the stability of the sports car whenever the driver pressed the brake during a turn. It also has a silicone alloy engine block designed with aluminum for weight-saving and durability.

  • Interior Spacing and Design

The Porsche 928 was a 2+2 coupe, which means there were two seats in the front and another two smaller seats in the rear. The rear seats had to be folded for more cargo space, and there were sun visors placed over all the seats. While this is a sports car with back seats, it doesn’t offer a lot of space for passengers, so it won’t be ideal for taller or bigger adults.
