The Porsche 928 was the company’s first V-8-powered automobile, and it was also the only coupe with a front-mounted V-8. The 928 was created in the 1970s as a replacement for the Porsche 911, but it was eventually exchanged next to the rear-engine sports vehicle. From 1977 through 1995, Generation was on the air. The 928 is Porsche’s sole luxury superb tourer to date, and it has been traded in several versions. In addition to the standard model, Porsche added a S variation and renamed it the 928 S4. The 928 was thereafter offered in Club Sport (C.S.) and G.T. trim levels, with the GTS being the only option for the final four model years. The 928 gained a following and is today regarded a classic, despite not being as popular as the 911.

Design and Specifications:

The 928 highlighted a large, front-mounted and water-cooled V8 engine forcing the rear wheels. Originally relocating 4.5 L and highlighting a single overhead camshaft design, it was estimated at 219 hp (222 PS) for the North of American business and 240 PS (177 kW; 237 hp) in other markets. Porsche improved the engine from mechanical to electronic fuel injection in 1980 for U.S. models, although power persisted the same. This figure marked a major change in trend for Porsche (started with the intro of the 924 in 1976), whose cars had used only rear- or mid-mounted air-cooled plane four or six-cylinder engines.


Porsche applies a transaxle in the 928 to assist manage 50/50 front/rear weight distribution, supporting the car’s balance. Although it counted more than the difficult-to-handle 911, its also neutral weight balance and higher power output gave it comparable performance on the road. The 928 was considered as the more relaxing car to drive at the time. It originated with either a five-speed dog leg manual transmission or a Mercedes-Benz-derived automatic transmission, formerly with three speeds record, with four-speed from 1983 in North America and 1984 in other markets. More than 80% of the cars had automatic transmissions. The specific percentage of manual gearbox cars for the entire stock run is unknown, but it is between 15 and 20%.

Styling Changes:

Styling was identical in both 1978 and 1979, with the body requiring both front and back spoilers. From 1980 (1983 in North America) through 1986, front and rear spoilers were on “S” models, rear spoilers being combined. From 1987 through 1995, the front spoiler was adjusted into the nose, the rear spoiler became an isolated wing rather than an integrated piece, and side skirts were combined. The rear tail-light configuration was also changed from earlier models. GTS models had vast rear fenders added to provide more room for 9-inch wide wheels. Another easily obvious visual difference between different variants is the styling of the wheels. The initial 928s had 15-inch or 16-inch “phone dial”-style wheels. Most 1980s 928s had 16-inch slot “flat disc” type wheels. The CSS, S.E.s and 1989 G.T.s had 16-inch “Club Sport” wheels; the G.T.s had 16-inch “Design 90” style wheels which were also options on same time S4s (connection with the 944 as well), the GTS used two modifications of the 17-inch “CUP” wheels.

Porsche 928 Engine Performance :

The 928 was expected to have a V6, but thankfully for 928 fans, Porsche chose an all-aluminum 4.5 liter 16-valve SOHC V8. This engine also boasted the world’s longest (Gilmer-type and toothed) timing belt in a generation vehicle — approximately 7 feet in length when laid out.


Suspension and Drivetrain:

Different drivetrain and suspension components were tested in Porsche, Mercedes, Opel, and Audi vehicles. The source cars had to be chopped, stretched, or expanded in certain cases to accommodate the 928 drivetrains and suspension, so Porsche engineers went to great lengths. Later, full-scale ideas and prototypes were put through rigorous testing in Africa’s deserts and in Finland’s ice. Crash tests were meticulously documented, with the 928 fairings exceeding the 5mph specifications of the day.

The engineers were rightfully proud of their accomplishments, but the first global gas calamity struck in the middle of the Porsche 928’s development. In this situation, the Board of Directors had to determine whether or not to move forward with ‘Projekt 928.’ As we now know, the project would move forward, and Porsche was willing to stake its future on the V8 platform.

The coachwork was designed behind closed doors alongside 911 manufacture. Many full-scale replicas of that spectacular body and cockpit were built and flown through. As the project neared completion, the Board of Directors was given a rolling example, which they would eventually approve. The new body shape is the original Porsche 928, which was unveiled to the public at the Geneva Motor Show in March 1977 (note 1), and later became the Porsche 928.

The Axle of Weissach: 

The automobile astonished the world when it was unveiled, garnering both acclaim and criticism. Because of its numerous upgrades, the 928 was promptly named Car of the Year. For example, the aluminum engine block and heads, as well as the Weissach axle” (in honor of the Porsche R & R&D center where it was invented). The Weissach axle was designed to decrease lift-throttle oversteer by allowing the rear suspension to adjust automatically while turning. The Weissach axel is one of the marque’s most recognizable features, and it has been adopted across the model series.


Torque tube and information about double disc clutches. To avoid the damping effect, the 928 battery is attached to the rear transaxle. The 928 boasts a near-perfect weight balancing combination of 50/50 front to rear thanks to its front-engine, rear-transaxle configuration.


S-type front and rear spoilers, as well as sport seats, are included in the 1981 competition package (see next web section on the 928 S). The Euro S’s biggest attraction, the 4.7 liter V8, would not arrive in the United States until 1983. There was a special 928 Weissach variant made. Champagne gold metallic paint, brushed gold alloy wheels, a two-tone interior, and the exceedingly collectible three-piece Porsche luggage set were all featured on the 911 Weissach. Only 205 of these automobiles were made.

Production took place alongside the 911 automobiles at the plant in Stuttgart – Zuffenhausen, removing any uncertainty about the client car’s manufacturing base. It’s interesting to note that, despite its lineage, the Porsche 928 has never garnered the same level of adoration as the air-cooled Porsches. Despite the press hailing it as the best GT Car Porsche has ever made, it continues to surprise those in the know and those who have surrendered to its relentless push via top acceleration.


By the late 1960s, Porsche had strongly built itself as a developer of high-performance sports cars. At the start of the 1970s oil crisis, officials, including owner Ferdinand Porsche, started to observe enhancing a more fuel-efficient luxury touring car to the record. Managing director Ernst Fuhrmann was motivating Ferdinand to support the development of the new model because the then-current flagship model, the 911, was approaching the limits of its potential. Fuhrmann concluded that the company’s future relied upon grand touring cars with standard engines except for unconventional sports cars. The sales of the 911 in the mid-1970s appeared to confirm that the model was surrounding the end of its economic life cycle. Fuhrmann envisioned the new range-topping grand tourer design as the best possible mixture of a sports coupé and a luxury sedan. It would set it aside from the 911, with its almost spartan interior and true sports car production. The points were that the car had to compete on par with contributions from Mercedes-Benz and BMW while also being victorious in the United States, Porsche’s main business at the time.

Which Porsche 928 to Buy?

Probabilities are that if you fancy a 928, you’ll already understand what you want: either the design description of the new car (no spoilers, no side strips, Pascha interior, telephone-dial alloys) or the sheer speed and greater luxury of the S4-and-later models. Customers manage to fall into one or another camp. 

1994 Porsche 928 top speed


  • 0 to 60 MPH N/A.
  • Best Speed 171 mph manual/168 mph Tiptronic.

The Fastest naturally Aspirated Vehicle in the World:

On August 7, 1986, the American racing driver Al Holbert established a speed record at Bonneville in a pre-production 928 S4. This 928 would adapt 171.110 mph in the flying mile and 171.926 mph for the flying kilometer. In March 1986, the equivalent car reportedly did 180+ mph at Nardo. Still, the Bonneville run cleared the United States Auto Club official report at the time for International Category of A, Group 2, Class 9, for usually aspirated vehicles. That made 1987’s 928 S4 the most active non-turbocharged composition car in the world. . Later on that year, the 928 S4 s went on to run a 180-plus mph top speed at Italy’s famed Nardo top-speed ring.

Pikes Peak:

The second oldest auto race in the U.S.The Pikes Peak International Hill Climb is t; a 12.42 mile (19.99 km) area with 156 turns to begin at 9390 ft and ending at the 14110-foot summit for the Pikes Peak. In 2007, 2008, and 2009 American racing driver Carl Fausett received his specially adapted and supercharged 1978 Porsche 928 to the Pikes Peak International Hill Climb and competed in the Open Division. Fausett won third in the Open Division in 2007 and again in 2009, where he was also the quickest 2WD car. At that time, many of the racecourses were rocks. Today the whole Pikes Peak Highway has been covered.

Some Facts about Porsche 928:

To replace the 911, a new model was developed:

Porsche considered the 911 to be reaching the conclusion of its evolution by the mid-late 1970s. The 928, along with the 924, was supposed to usher in a new era of front-engine, rear-drive Porsches that were more comfortable and unique to drive. The Porsche 928 was the company’s flagship model, outperforming even the powerful 911 Turbo from the 930 series. Finally, we all know how things turned out: the 911 is still in production today, whilst the 928 was discontinued about two decades ago. Here is the latest used stock of Porsche models

From 1993 to 1995, the 928 GTS received a redesigned V-8 engine that was bored and stroked to 5.4 liters, equipped with the most advanced four-valve-per-cylinder heads, and coupled to a new four-speed automatic transmission. The result was a 345 horsepower engine with a 0-60 mph speed of less than 6 seconds. Porsche only shipped 407 samples of the 928 GTS to the United States, with 928 sales at an all-time low due to the model’s age.

Automatic transmissions were installed in 928s:

Putting an automatic in a Porsche, especially one from the 1970s or 1980s, may appear foolish. The manual version of the 928, on the other hand, was not a great moment. The Porsche thoroughbred I drove drove as if it had been pulled from a Volkswagen Bus rather than a Porsche race car. Although the automotive press noted that the 928’s manual was not a demanding heavy suit when it was new, the automatic was the way to go. Another rationale for removing the third lever is to emphasize the 928’s easy, luxury first-class touring image.

Aluminum and galvanized steel are extensively used:

During its development, the Porsche 928 was one of the most advanced production automobiles to employ aluminum. Aluminum not only saves weight but also protects the Porsche 928 from rust. The floor pans, roof, and rear quarter panels were all made of rust-resistant galvanized steel. There’s a saying in Porsche champion country that if you see a 928 with a lot of rust, run the other way because something awful happened to it.


For the 1984 24 hrs of Daytona, Porsche obtained one of its innovative “All-aluminium” 928S to the Brumos Racing Team to be provided with specific instructions not to change the car in any way. Porsche was required to improve the appearance of the 928 in North America. The drivers Richard Attwood (G.B.), Vic Elford (G.B.), Howard Meister (USA) and Bob Hagestad (USA) were told to “drive the car.” During training for the 24-hour race, the drivers found the car to be somewhat unpredictable on the high banks of Daytona and required to add a rear wing to the car; Porsche denied the request. The Brumos team repaired the suspension set up to make the car more durable. The car finished 15th overall and 4th in the GTO class. In an interview, later on, one driver declared that were it not for a long pit stop to fix somebody’s injury, they would have ended in the top 5 overall. The car was later returned to Porsche and is now in the Porsche Museum.

Steering Systems with Rear-Wheel Drive (RWD):

The transmission is located in the rear of the car for improved weight distribution, but it also houses one of the 928’s signature features: the famous Weissach axle. This rear axle configuration is unique to the 928 and was named after the Porsche R&D center where it was developed. Its goal is to eliminate the toe-out tendency caused by mid-corner throttle rises, thus improving cornering grip and security. This equates to incredible mid-corner stability and grip, and with to the 928’s 50/50 weight distribution, it’s easy to execute not only in a straight line but also on the corners. The Weissach axle is a predecessor to active rear-wheel and even four-wheel steering modes and is the most sophisticated passive rear-wheel steering configuration. Mazda’s second-generation RX7 was one of the first vehicles to use comparable services.
