Buick Planning Flagship Luxury Sedan to Rival Lexus LS: The Return of the Park Avenue

While all the news from Buick as of late has been in regards to new smaller models and a move d0wn-market, the GM luxury brand is also planning a new flagship model. Targeted at the Lexus LS, the team at GMInsideNews has confirmed from sources inside GM that an early design for the new model has been approved and the team responsible for the car has been given a limited budget to continue developing the idea.

This new model would be based on the Premium Zeta architecture, much like the proposed (but not yet confirmed) Cadillac XTS. In order to keep these two models from competing too closely with each other, the Buick model would target the Lexus LS, while the Cadillac would be poised to take on the sportier BMW 7 Series.

Currently Buick does have a flagship sedan based on the Zeta architecture – sold in China as the Park Avenue. There's a possibility that this new model could also replace the Chinese Park Avenue and bring back the Park Avenue name to North America.
