At the 2015 Detroit North American International Auto Show, Buick unveiled the Cascada convertible – the badge-engineered cousin to an Opel of the same name. More exciting than anything else about the car, this model will finally bring Opel’s excellent 200 HP, 1.6 liter turbo to America’s shores.
But happily, we’ve been told, the 2016 Buick Cascada will not be the last North American model to make use of the power-dense beast.
The turbocharged, direct-injection four-cylinder in-question is an impressive design. It features balance shafts for smooth operation, a dynamic turbocharger boost strategy to minimize lag, and a host of sound and light-weighting features. That includes thin-wall cylinders, and low- and high-pressure resonators on the turbocharger compressor to rid the engine of any pronounced hiss.
This actually confirms speculation that we had back in April of 2013 that the new midsize direct-injection engine would cross the Atlantic. We’d suspected back then that it could make its way into the Chevrolet Sonic, Malibu, and possibly other models as well. We can officially check the box next to the 2016 Buick Cascada as the first North American GM product to use the new (to us) mill.
