Very simple. In Europe there were four versions:
"Corrado" (2E-engine)
"Corrado 16V" (KR / 9A-engine)
"Corrado G60" (PG-engine)
"Corrado VR6" (ABV-engine)
In the Uk there was a limited edition of the VR6 badged as "Storm"
In Germany there were some special models as well.
The G60 was sold as "Jet" - must have been around 1991 and 1992 - and there had been two "Exklusiv" -versions in 1989(G60) and 1993(16V and VR6). All three had no special badges at rear or front.
