I wish I knew enough about this stuff to make sense of it.
Thanks to TuuSaR in comments, I have some sort of confirmation that Saab still have some ongoing interest in the SVC engine. The confirmation comes by way of a European patent that was applied for earlier this year. As I said, my technical knowledge is very limited, but the patent application does state that:
An object of the invention is to provide a reciprocating engine having a variable compression ratio and having a compact design.
The patent application gives all sort of details about it and some diagrams that were waaaay over my head. You can view the application here.
The important thing, for you and I as average punters, is that this technology isn’t dead. Hopefully there’s some light at the end of the tunnel. It’s innovation like this that, if successful, could extend the life of the gasoline engine. And the life of Saab Automobile AB.
