CERTIFICAT DE CONFORMITÉ PORSCHE

Bienvenue sur le site officiel dédié à la délivrance de certificat de conformité Porsche et COC Porsche

 

The Porsche 928 is a luxury grand tourer produced by Porsche AG of Germany from 1978 to 1995. Originally intended to replace the company's iconic 911, the 928 combined the power, poise, and handling of a sports car with the refinement, comfort, and equipment of a luxury saloon. Porsche executives believed such a flagship would have wider appeal than the compact, quirky and sometimes difficult to drive 911.The 928 has the distinction of being the company's first production V8 powered model and the only coupé powered by a front-mounted V8 engine.

By the late 1960s Porsche had firmly established itself as a manufacturer of high-performance sports cars. Executives, including owner Ferdinand Porsche, were beginning to consider adding a luxury touring car to the line-up. Managing director Ernst Fuhrmann was pressuring Ferdinand to approve development of the new model due to concerns that the then-current flagship model, the 911, was 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 gran turismo model as being the best possible combination of a sports coupé and a luxury sedan. This would set it apart from the 911, with a relatively spartan interior and true sports car performance.

The 928 featured a large, front-mounted and water-cooled V8 engine driving the rear wheels. Originally displacing 4.5 L and featuring a single overhead camshaft design, it produced 163 kW; 222 PS (219 hp) for the North American market and 177 kW; 240 PS (237 hp) in other markets. Porsche upgraded the engine from mechanical to electronic fuel injection in 1980 for US models, although power remained the same. 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, originally with three speeds, with four-speed from 1983 in North America and 1984 in other markets. More than 80% had the automatic transmission. Exact percentage of manual gearbox cars for entire production run is not known but it is believed to be between 15 and 20%.

The COC Porsche  is available for all Porsche 928 built by the European market.

Styling was the same in both 1978 and 1979, with the body lacking both front and rear spoilers. From 1980 (1983 in North America) through 1986, front and rear spoilers were present on "S" models, rear spoilers being integrated into the hatch. From 1987 through 1995, the front spoiler was integrated into the nose and the rear spoiler became a separated wing rather than an integrated piece, and side skirts were added. The rear tail-light configuration was also different from previous models. GTS models had wider rear fenders added to give more room for 9-inch wide wheels. Another easily noticeable visual difference between versions is the style of the wheels. Early 928s had 15-inch or 16-inch "phone dial"-style wheels, while most 1980s 928s had 16-inch slotted "flat disc" wheels, CSs, SEs and 1989 GTs had 16-inch "Club Sport" wheels, later GTs had 16-inch "Design 90" style wheels which were also option on same period S4s (shared with the 944 as well), the GTS used two variations of the 17-inch "CUP" wheels.
