Porsche 928 Origins
The Porsche 928 was unveiled at the 1977 Geneva Motor Show in preparation for the 1978 model year sales. It was a two-door coupe in the grand tourer category that had a front-engine, rear drive layout. The goal of Porsche was to have long-running sales of the Porsche 928, so the design and style had to be such that they wouldn’t become dated over time. Also, with competitors like BMW and Mercedes, the Porsche 928 had to not only be more comfortable than previous Porsche models, but its design and interior had to be more refined and luxurious as well.About the Porsche 928
Since Porsche began creating cars in the late 1940s, the company only produced six models that have had the engine mounted at the front of the vehicle. Four of these models were coupes and included the Porsche 928. Additionally, it's the only model that has a front-mounted V-8 engine. It was also the first mass-produced Porsche vehicle to contain a V-8 engine. The front-mounted engine layout was chosen to reduce noise produced by a rear-engine layout and to also provide adequate passenger space that would be lost if a mid-engine layout was adopted.Porsche 928 Features
The first Porsche 928 to hit the roads in 1977 was equipped with a 4.5-liter, water-cooled, V-8 engine that produced 219 horsepower. As well as being the first Porsche equipped with a V-8 engine, it was also the first to feature a water-cooled engine instead of the air-cooled engines used in all previous Porsche models. To provide a 50/50 front/rear weight balance and better handling, Porsche included a transaxle in the Porsche 928. The first models were equipped with either a five-speed manual transmission or a three-speed automatic transmission. The engines in U.S. models were upgraded to include electronic fuel injectors instead of mechanical ones. The automatic transmission was upgraded to a four-speed during 1983 for North American models.
Most of the body was built from steel, but the aluminum was used for the front fenders, hood, and doors to reduce the weight of the car. The bumpers were made from polyurethane and integrated into the body to improve visibility from within the car, as well as reduce the amount of drag. They were covered with plastic that was the same color of the car, which was unusual at that time. By moving the engine to the front of the car, the Porsche 928 had a luggage area at the rear, which was accessed through a hatchback-style door. The two seats in the rear of the car could be folded down to provide more cargo space, if needed.Porsche 928 Evolution
The Porsche 928S was introduced to the European market for the 1979 model year, but this design did not reach the North American market until 1982. In 1980, front and rear spoilers were added to the S models with the rear spoiler integrated as part of the hatchback. The spoilers remained this way until 1987, when the front spoiler was integrated into the nose, and the rear spoiler became a separate wing with added side skirts. The 928S model was fitted with a 4.7-liter, V-8 engine that had a power rating of 234 horsepower in the U.S.
In 1986, an improved Porsche 928 was released, denoting the 928S 4 for the fourth series of the car. It was equipped with an updated five-liter, V-8 engine with 316 horsepower and 317 lb-ft of torque. Instead of the dual-disc clutch unit, the Porsche 928S 4 had a new single-disc unit. As well as modifying the mechanical parts of the car to provide more power, Porsche also redesigned the car to reduce drag.
For the 1990 model, Porsche changed the name back to the Porsche 928S from the 928S 4. Changes included the addition of dual airbags, a tire pressure monitoring system, and a limited-slip rear differential. Porsche became the first to manufacture a car with airbags for both the driver and the passenger. The engine was modified so that it now produced 326 horsepower with a five-speed manual transmission. Model designations were GT for the manual transmission and S for the automatic. These were cut for the 1993 model year in the U.S. when it became the Porsche 928 GTS. Production ceased in 1995.
