Opel/Vauxhall has certainly been busy this year – after the Mokka SUV and upcoming Adam city car, which is set for a Paris debut, comes the announcement of a third model name into the fold.

It’s called the Cascada, and it’s a four-seater mid-size convertible set to make its market debut in early 2013 – unlike the Adam and the Holden and Chevrolet Trax, it’s not going to be a Paris debutant. The photos are pretty much teasers too, offering only a view of the top half of the car.

The name of the 4.70-metre long offering is derived from the Spanish word meaning waterfall, all to convey a rhythmic, dynamic and flowing nature. That the tones are usually associated with open-air driving also helps, one supposes.

No tech details as yet on the soft-top, aside from the point that the car’s fabric roof is operable while the car is moving, at speeds of up to 50 km/h. More when it flows in, later in the year.
