Buick currently sells the Encore and Enclave crossovers but a third tall-riding model is reported to be joining its lineup in the coming years.

The origin of the speculation is the recent siting of a prototype for a smallish crossover sporting some telltale Buick design themes, near a General Motors facility in Michigan.

According to GM Inside News, a new crossover dubbed the “Anthem” is in the works and destined for Buick’s lineup, most likely in the second half of 2014, making it a 2015 model. The vehicle would target the likes of the Acura RDX, Audi Q5 and upcoming Lexus NX.

Underpinning it would be an overhauled version of GM’s Delta II platform, possibly dubbed D2XX, which will replace both the Delta II car and Theta crossover platforms in the GM portfolio.

D2XX will spawn everything from hatchbacks to crossovers and will feature in the next generation of the Chevrolet Volt and Cadillac ELR extended-range electric cars, as well as in the next Buick Verano, Chevrolet Equinox, GMC Terrain and Opel Astra. And we can now add the Buick Anthem to that list.

The new Anthem isn’t expected to be a North American exclusive; a version should also be sold in China, Buick’s biggest market.

As for engines, expect similar offerings to that found in the Verano. That means a base 2.4-liter unit and a more potent 2.0-liter turbo.

Stay tuned for an update.
