A video made by SAAB, aiming to show the background of Project 99: the SAAB 99 EMS. The Saab EMS model sold to the public did not have a 16v head.
But the racing version did. It was a pretty “beefed up” engine and like many other “high-performancing” engines of that time, it was inspired by the Cosworth BDA design.
Some say that the 16v head, Many Saab people think that was inspired by Cosworth, was originally made for a Volvo engine.
