Opel has registered the "Cascada" and "Calibra" nameplates with the U.S. Patent and Trademark Office.

Opel has registered the "Cascada" and "Calibra" nameplates with the U.S. Patent and Trademark Office.

Last year GM's CEO Dan Akerson expressed his intentions to bring the Opel Cascada stateside and his statement was later fueled by a September rumor indicating work on modifying the convertible had started. Now, Opel has trademarked the "Cascada" moniker in the United States which possibly means General Motors will introduce a Buick-badged Cascada in the near future since the Opel name is not used in U.S.

As far as the Calibra is concerned, there aren't any details about the car which in the past was basically a two-door coupe derivative of the Vectra (a precursor of the Insignia). Opel did show back in 2007 a GTC Concept which would have been a worthy Calibra revival if turned into a production model but nothing materialized.

We don't exclude the possibility that through these actions Opel could simply want to protect the two names.
