928 (1978-1995)

Technical data

The Porsche 928, a grand touring car boasting a 2+2 seating arrangement, was manufactured by Porsche from 1978 to 1995. Initially, it was considered as a potential replacement for the Porsche 911, aspiring to blend the performance and handling of a sports car with the comfort, spaciousness, and ride quality of a luxury vehicle. Although Porsche executives speculated that the 928 would appeal to a broader audience compared to the compact and somewhat outdated 911, they ultimately decided to keep both models in production concurrently. The 928 showcased a front-mounted, water-cooled V8 engine that powered the rear wheels. Utilizing the transaxle principle aided in achieving a balanced 50/50 front/rear weight distribution. Initially, with a displacement of 4.5 liters and a single overhead camshaft design, it delivered 240 PS (177 kW; 237 hp) in Europe, while emissions regulations reduced output to 222 PS (163 kW; 219 hp) for North American models. In 1980, the car saw an increase in both displacement and output with the introduction of the 4.7 L 928 S, initially rated at 221 kW; 296 hp (300 PS) for European versions and later upgraded to 228 kW; 306 hp (310 PS) in 1984. The original 16v engine underwent further development until its final iteration in the 1985 model year with the S/S2 model, producing 310 PS (228 kW; 306 hp) in European specification, thanks to higher compression and other enhancements. In 1985, Porsche updated the North American 928 S, replacing the 4.7 L SOHC engine with a new 5.0 L DOHC unit generating 215 kW; 292 PS (288 hp), sometimes informally referred to as S3 models. European models retained the 4.7 L engine, with some countries offering a lower compression 32-valve engine with catalytic converters. The 928 S4 debuted in the second half of 1986 as a 1987 model, featuring an updated 5.0 L V8 producing 235 kW; 316 hp (320 PS) for all markets. Production of the S4 ceased at the end of the 1991 model year, paving the way for the final iteration, the 928 GTS. Available in late 1991 as a 1992 model in Europe and in the spring of 1992 as an early 1993 model in North America, the GTS featured changed bodywork, larger front brakes, and a new, more powerful 5.4 L, 350 PS (257 kW/345 hp) engine. In 1995, fully equipped GTS models could surpass the US$100,000 mark, positioning them as some of the priciest cars available at the time. Despite their exceptional capabilities and extensive standard features, this steep price tag significantly hindered sales. Consequently, Porsche ceased production of the GTS model that year, with just 77 units shipped to the United States. In total, worldwide production across all years amounted to just over 61,000 cars.
