Vauxhall has released first details and teaser images of their new mid-sized convertible called Cascada, that essentially replaces the Astra TwinTop.

The Cascada is 70mm longer than Audi’s A5 Convertible, measuring 4.7 metres in length. The roof can be opened or closed at the touch of a button, at speeds up to 30mph.

Cascada is a Spanish word and means “waterfall”. It is the third new name to be introduced by Vauxhall this year, following Mokka and ADAM.

Vauxhall’s Chairman and Managing Director, Duncan Aldred, was enthusiastic about the lift each model offered the company: “Cascada, along with ADAM and Mokka, will bring a fresh and exciting dimension to our product line-up for customers. This year is genuinely a new chapter in Vauxhall’s long history, and I’m pleased that we’re able to enter the mid-size convertible sector with Cascada, and continue to refresh people’s perception of our great brand.”

Vauxhall won’t be showing the Cascada at the Paris Motor Show as it wants the compact ADAM to take centre-stage. Official debut is very likely sometimes in mid October, with sales starting in early 2013.
