It is a computer controlled turbocharger boost system. It is nothing new, but it is very expensive and results in a very complex engine. Since Saab was owned by GM at the time, makes you wonder why GM never adopted the technology to their flex-fuel engines. Maybe because they were only interested in the CAFE advantage their flex fuel dinosaurs provided to their bottom line.

It would actually be news if an engine manufacturer built a new engine that was simple and just ran efficiently on E85. That would finally show confidence in ethanol as a fuel source.
