The Porsche 928 is a luxury GT car which was produced by Porsche AG of Germany from 1978 to 1995. Originally intended to replace the company's well-known and famed 911, the 928 combined the power, poise, and handling of a sports car with the refinement, comfort, and equipment of a luxury sedan to create what some Porsche executives thought would be a vehicle with wider appeal than the compact, quirky and sometimes difficult 911. The car has the distinction of being the company's only coupe powered by a front-mounted V8 engine, and the company's first production V8 powered model.
By the late 1960s, Porsche had changed significantly as a company, and executives including owner Ferdinand Porsche were toying with the idea of adding a luxury touring car to the line-up. Managing Director Ernst Fuhrmann was also pressuring Ferdinand to approve development of the new model in light of concerns that the current flagship model at the time, the 911, was quickly reaching the limits of its potential. Slumping sales of the 911 seemed to confirm that the model was approaching the end of its economic life cycle. Fuhrmann envisioned the new range-topping model as being the best possible combination of a sports coupe and a luxury sedan, something well equipped and comfortable enough to be easily driven over long distances that also had the power, poise and handling prowess necessary to be driven like a sports car. This set it apart from the 911, which was intended to be an out-and-out sports car.
Porsche engineers wanted a large-displacement engine to power the 928, and prototype units were built with a 5-litre V8 producing close to 300 hp. The resulting M28 engine eventually designed has multiple unusual features. Its bore spacing is 122 mm, almost exactly the same size as a Chrysler 426 hemi or a big block Chevrolet engine. This engine uses thick aluminium cylinder barrels, hence the lower displacement. The engine was designed for air flow first, thus the spark plugs are located at the top of the head. The four-bolt bearings are sizeable, and are fed oil via grooves in the bottom surface of the block. The oil and water pumps are powered by the timing belt, and the design of the engine allows for sufficient air flow with a very low hood.
The 928 featured a large, front-mounted and water-cooled V8 engine driving the rear wheels.This design marked a major change in direction for Porsche (started with the introduction of the Porsche 924 in 1976), whose cars had until then used only rear- or mid-mounted air-cooled flat engines with four or six cylinders. Porsche utilized a transaxle in the 928 to help achieve 50/50 front/rear weight distribution, aiding the car's balance. Although it weighed more than the difficult-to-handle 911, its more neutral weight balance and higher power output gave it similar performance on the track. The 928 was regarded as the more relaxing car to drive at the time. It came with either a five-speed dog leg manual transmission, or a Mercedes-Benz-derived automatic transmission, The body, styled by Wolfgang Möbius under guidance of Anatole Lapine, was mainly galvanized steel, but the doors, front fenders, and hood were aluminium in order to make the car more lightweight. It had a substantial luggage area accessed via a large hatchback. The new polyurethane elastic bumpers were integrated into the nose and tail and covered in body-coloured plastic; an unusual feature for the time that aided the car visually and reduced its drag.
The 928 included several other innovations such as the "Weissach Axle", a simple rear-wheel steering system that provides passive rear-wheel steering to increase stability while braking during a turn, and an unsleeved, silicon alloy engine block made of aluminium, which reduced weight and provided a highly durable cylinder bore. Porsche's design and development efforts paid off during the 1978 European Car of the Year, where the 928 won ahead of the BMW 7 Series, and the Ford Granada. The 928 is the only sports car so far to have won this competition.
Porsche introduced a refreshed 928 S into the European market in 1980 model year, although it was 1983 before the model reached North America. Externally, the S wore new front and rear spoilers and sported wider wheels and tires than the older variant/
Porsche updated the North American 928 S for 1985, replacing the 4.7 L SOHC engine with a new 5.0 L DOHC unit sporting four valves per cylinder and producing 288 hp. Seats were also updated to a new style, these cars are sometimes unofficially called S3 to distinguish them from 16-valve "S" models. . In 1986, revised suspension settings, larger brakes with 4-piston calipers and modified exhaust was installed on the 928S, marking the final changes to old body style cars. These were straight from the 928S4, which was slated to debut a few months later. These changes came starting from VIN 1001, which means that the first thousand '86's had the old brakes, but later cars had the later systems. This later 1986 model is sometimes referred to as a 19861⁄2 or 1986.5 because of these changes. The name is a little misleading as more than 3/4 of the 1986 production had these updates.
This very nice example has been well cared for its entire life and always kept garaged, The body is entirely rust and corrosion free, and the paint is in excellent condition, the interior is in excellent condition as well with soft supple leather and original rugs and mats in near perfect condition. The car runs perfectly. thje AC blows nice and cold, and it has no leaks whatsoever. It drives and handles like a true World Class Super Car should. All the books and tools accompany the car. It appears the guage cluster has been replaced so the true mileage is unknown.
Finished in a striking color combination, this well kept example is poised for future appreciation in the marketplace as the rapid increases in 911 values have started to effect the 928. Here we have a an affordable supercar that you can drive and enjoy, is easily serviced and maintained, and sell for a profit down the road!
