In the Detroit auto GM even released a teaser shot of the production vehicle. The crossover is expected for the 2013 model year. Industry sources have said it will be built on a version of GM's front-wheel-drive Gamma subcompact platform, which underpins the Opel Meriva MPV and Chevrolet Sonic.
The Encore will join the full-sized Enclave crossover and is part of GM's continued build-out of Buick's lineup.
The Verano, Buick's first compact car in more than a decade, began arriving in showrooms last month. The Regal mid-sized sedan was launched in 2010.
GM said it plans to reveal a photo of the Encore, little by little in the weeks leading up to the Jan. 10 reveal at the auto show.
