Automotive News has managed to obtain comprehensive details about Buick's forthcoming lineup changes.

First and foremost, Buick will (finally) be getting its own version of the Opel Cascada at the beginning of 2016. They could opt for another name while under the hood will probably be a 4-cylinder 2.0-liter turbocharged gasoline engine generating 250 bhp (187 kW) borrowed from the Regal and Verano.

Speaking of the Verano, it's set to receive a second generation in 2016 and will go on sale as a 2017 model year riding on the same D2XX platform as the next-gen Opel/Vauxhall Astra and Chevrolet Cruze. It will continue with the aforementioned 2.0 turbo engine but should also receive a newly developed 4-cylinder 1.5-liter turbo serving as the base motor.

Sometime in 2017 there will be a next generation Regal programmed to be commercialized as a 2018MY and will essentially be Buick's version of the next-gen Insignia set to ride on the E2XX platform.

The first model to use the E2XX platform will be the next-gen LaCrosse expected towards the end of 2015 (as a 2016 model year) which will feature a revolutionary design according to GM executives, with a four-door coupe silhouette being very possible.

Buick also plans to revitalize its crossover offerings as a facelift for the Encore is set for a 2016 release while an all-new model will be out in 2018. Recently revealed in China, the Envision will also hit stateside probably with a different name in the second half of 2015 as a 2016MY.

Lastly, the Enclave will get a new generation in 2017 and will use an updated variant of the Lambda platform which underpins the current model. Expect the model to go on a diet and receive smaller engines as well as a 9-speed automatic transmission.
