For 2016, Buick introduces an all-new luxury convertible. The Cascada is based on the Delta 2 platform currently used by several GM cars, including the Chevrolet Cruze here in the U.S. as well as the Opel Cascada, which GM sells in Europe. The Cascada also shares its suspension with both the Regal and LaCrosse, which makes the car plenty comfortable yet sporty enough to make for an enthusiastic driving experience. Power comes from a 1.6L turbocharged four, which sends 200 horsepower and 206 pound-feet of torque to the front wheels through a 6-speed automatic transmission. The Cascada is offered in either base or Premium trims, and each features a power soft top that retracts in just 17 seconds, at speeds up to 31 mph. The 2+2 configuration features rear seats actually suited for occupancy, while the trunk features more than 13 cubic feet of space when the top is up. All of which broadens the appeal of the Cascada as a practical convertible for carrying family and friends. Even the base Cascada is nicely appointed, with 20-inch alloy wheels, HID headlights and LED taillights. Inside are amenities including IntelliLink navigation, a premium sound system with a 7-inch touchscreen, 4G LTE in-car WiFi connectivity, rear vision camera with park assist, remote start, and heated front seats and steering wheel. In the Cascada Premium, you'll find all of the above plus standard advanced safety features like forward collision and lane departure warnings, front and rear park assist, automatic headlights and rain-sensing wipers.
