After a relatively quiet past 12 months, Buick is about to embark on a new model explosion that will see all-new crossover and convertible models added to its lineup. The new crossover has just been revealed in China as the Envision and is due in U.S. showrooms in the second half of 2015, as a 2016 model. The convertible, meanwhile, will be a version of the striking Opel Cascada sold overseas, possibly on sale here as early as 2016.

But what about the rest of the Buick lineup? Automotive News (subscription required) has all the details.

Starting with the Verano, we should see a second-generation of the compact sedan launched in 2016, most likely as a 2017 model. While the current model only arrived in 2012, General Motors Company’s [NYSE:GM] plans to introduce its new D2XX compact car platform in new versions of the Chevrolet Cruze and Volt means the Verano platform-mate is also getting a redesign. Prototypes have already been spotted.

Moving up to the Regal, we should see a next-generation model in 2017, as a 2018 model. The Regal will once again be twinned with the Opel Insignia, a new generation of which is already in development. The new Insignia will arrive first, most likely in 2016. The cars will be based on GM’s next-generation Epsilon platform, dubbed E2XX.

A new version of the LaCrosse is due late next year or in early 2016. It will be listed as a 2016 model, giving the current LaCrosse a six-year shelf life. The new LaCrosse will be GM’s first model to ride on the E2XX platform and is expected to transform into a sporty four-door coupe. This will help differentiate it from the Regal, which will remain a conventional sedan. Though it's yet to be confirmed, a version of the new LaCrosse could be sold by Opel as a new flagship and by Holden as a successor to its Commodore.

In the crossover department, the subcompact Encore will receive a subtle facelift, most likely for the 2016 model year. The 2016 model year will also see the arrival of the Envision, which may end up being called something different for the U.S. market.

Finally, we should see the Enclave redesigned for the 2017 model year. It will sit on an enhanced version of the current model’s Lambda platform that will benefit from lighter construction and alternative drive powertrains. A previous plan to spawn a Cadillac crossover with third-row seating from this platform has been dropped.
