The special models get several exterior cues designed to set them apart from the competition. Details include special 18-inch wheels with machined faces and a rear spoiler. It's all part of a larger plan to add more "design-focused" choices to the lineup.
Pricing on the Sport Touring models has not been announced.
"These new ST models underscore the importance of design choices," said Duncan Aldred, vice president of Buick, in a statement.
Previously, Buick said a new 2016 Buick Encore Sport Touring model will arrive at dealerships in the fall.
Edmunds says: Buick adds some sporty style across the lineup, giving car shoppers another reason for a showroom visit.
