The new China-built Envision crossover won’t be Buick’s only premiere at next week’s Detroit Motor Show, as brand officials hinted at a second ‘surprise’ debut.

Speaking to The Detroit News, Duncan Aldred, U.S. vice president of Buick, said: “We have a very special program, and we had a surprise last year, so we’ll see if we can do something this year as well.”

At the 2015 Detroit Motor Show, Buick revealed the Cascada Convertible and the well-received Avenir luxury concept car.

While GM won’t divulge what they have in store for Detroit, speculation is rife as to what it could be, ranging from a new Verano built on the latest Astra and replacements to the Enclave SUV and Regal sedan, to an Opel-based concept car.

Kelley Blue Book analyst Akshay Anand suggested to the publication that Buick may show a production version of last year’s Avenir study or a similarly large sedan to sit on top of the new LaCrosse. . “I think they need some flagship sedan to get people excited about the brand,” he said. However, as pointed out by The Detroit News staff, Buick officials told reporters in November that, for the time being,  the LaCrosse would be the brand’s top model.

Recently, Buick trademarked the ‘Tourx’ and ‘Regal Tourx’ names, which point to a taller riding station wagon, and specifically, Opel’s Insignia Country Tourer.
