Buick has officially unveiled the 2016 Cascada, ahead of its debut at the North American International Auto Show.

Set to become Buick's first convertible in 25 years, the drop top is essentially rebadged version of the Opel / Vauxhall Cascada. As a result, it features LED-infused headlights and a soft-top that opens in 17 seconds at speeds up to 31 mph (50 km/h). The car also has a rakish windscreen, chrome trim and 20-inch alloy wheels.

The upscale styling continues in the cabin as there's high quality materials and metallic accents. Buick declined to go into specifics but confirmed the car will have heated front seats and an IntelliLink infotainment system with a 7-inch display. The model also has electric seat belt presenters and a rear-seat entry system that automatically moves the front seats forward.

On the safety front, the Cascada will have a rearview camera and pop-up rollover bars. There's also rain sensing wipers and a lane departure warning system.

A turbocharged 1.6-liter four-cylinder engine resides under the hood and produces 200 bhp (149 kW) and 206 lb-ft (280 Nm) of torque - 221 lb-ft (300 Nm) with overboost. It is connected exclusively to a six-speed automatic transmission.

The Buick Cascada will go on sale early next year and pricing will be announced closer to launch.
