The timing of the wagon's arrival wasn't disclosed at the meeting. It would likely arrive within a year of the sedan, sometime in late 2018. It is expected to share its underpinnings with the next-gen Opel Insignia wagon.
A Buick spokesman declined to comment.
Americans are indifferent to wagons, to put it nicely. The body style represents 1 percent of the market, IHS Automotive estimates. The research firm doesn't expect that figure to budge in coming years.
Buick has had some success with its so-called white-space strategy of targeting subsegments ignored by rivals. The early 2013 introduction of the Encore beat a slew of other diminutive crossovers to market, and the vehicle has emerged as Buick's volume nameplate. Another example: the Cascada convertible that bowed in January.
They haven't all been hits, though. The Verano was billed as a white-space play when introduced in late 2011 as a mid-$20,000s premium compact sedan. Buick will phase out the Verano this fall.
