While the Cadillac CTS coupe is confirmed for production in June of next year a convertible version of the svelte two-door is shaping up to be just a dream as latest reports claim GM has dropped plans for such a model. Despite the positive reception received by the CTS Coupe Concept at January’s Detroit Auto Show, according to an inside source a convertible CTS won’t be heading for production.

Just this week Nissan revealed it would launch a convertible version of its premium Infiniti G37 coupe and next year Mercedes-Benz is expected to launch its next-generation CLK. Lexus has also been testing a convertible prototype of its own IS, so it comes as a surprise GM would totally ignore the market. In an interview with Edmunds, Cadillac spokesman David Caldwell declined to comment on the subject.

As for the coupe, GM is scheduled to start production of the car in June next year with the first models likely to appear in showrooms in the third quarter of the year. Prototypes of the car spotted testing recently closely resemble the concept and include the same fastback shape and sharp lines.
