Porsche's first run of the 928 was revolutionary in more ways than one. Hailed as the European Car of the Year in 1978, the 928 looked like nothing else on the market and more importantly, nothing else Porsche had ever made before. The 928 started life as Porsche's environmentally friendly alternative, offering four seats and controlled emissions thanks to the low-stressed V8 and some advanced engine management. However, by the end of the 928's lifespan ​Porsche had made a number of alterations resulting in the fierce 928 GTS, which finally offered a competitive top speed of 170mph.
