How does Buick ensure the 2016 Cascada convertible will stay dry when April showers come calling? By making it rain on the assembly line, assuring cloudbursts will be no match for Cascada when it hits dealerships in early 2016.

Specialized water test booths, located at the end of Cascada’s assembly line, will allow freshly built cars to roll off the line and into testing. Each booth has at least 124 individual nozzles, which will quickly immerse the Cascada in a miniature rainstorm for 10 minutes.

“Convertibles are best enjoyed when it’s warm and sunny, but Cascada has been designed and engineered to be used year-round, regardless of the weather,” said John Dolch, program quality manager for Cascada. “Not only is Cascada’s top engineered to be weatherproof in extreme conditions, but each and every Cascada built will also be put through a rigorous water test.”
