Porsche executives believed such a flagship would have wider appeal than the compact 911. The 928 has the distinction of being the company's first production V8 powered model and its only coupé powered by a front-mounted V8 engine. ==Conception== 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 due to the need of a car using less fuel and being more usable in the wake of the 1970s oil crisis.
When increasing concern within the company over price and availability of fuel during the oil crisis of the 1970s became an issue of contention, smaller engines were considered in the interest of fuel economy.
This design marked a major change in direction for Porsche (started with the introduction of the 924 in 1976), whose cars had until then used only rear- or mid-mounted air-cooled flat engines with four or six cylinders. Porsche utilised a transaxle in the 928 to help achieve 50/50 front/rear weight distribution, aiding the car's balance.
Both sides finally settled on a 4.5 L, SOHC per bank 16-valve V8 rated at ( in North America), which they considered to have an acceptable compromise of performance and fuel economy. The finished car debuted at the 1977 Geneva Motor Show before going on sale later that year as a 1978 model.
The Porsche 928 is a luxury grand tourer produced by Porsche AG of Germany from 1978 to 1995.

Porsche upgraded the engine from mechanical to electronic fuel injection in 1980 for US models, although power remained the same.
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.
