Drivers, the Stelvio pass is a well-known terrific pass to drive, for the scenery and the driving.
What's another notable pass within a couple of hours?
The only obvious ones to me are the Hahntennjoch and the San Bernadino pass.
Perhaps locals would know other Great Passes in that neck of the woods?
(Unfortunately I could not find a comprehensive "passes of Europe" map. Alert! User Relaxed has found just that.)
